TECHNICAL FIELD

[0004] The present invention relates to systems and methods for the integration of auxiliary energy production systems, and more particularly, to an auxiliary power integration system for integrating auxiliary power sources to a power grid and/or to a load.

BACKGROUND

[0005] Wind-powered turbine and photovoltaic (PV) array auxiliary power generation technologies are available at the consumer level. Power supply systems employing auxiliary power generation systems may further include power storage systems, such as batteries, to store energy for when wind and solar power is not available. Auxiliary power generation and storage systems are often non-standardized. As such, consumers are left without a simple, cost effective means for integrating consumer owned and operated power generation systems, consumer owned and operated energy storage systems, and/or the utility power grid.

[0006] Accordingly, the need exists for power supply systems and methods that facilitate the integration of auxiliary power systems, such as renewable energy generation technologies and energy storage technologies, with the utility power grid to supply power to a load. More specifically, the need exists for configuring and auxiliary power integration system for integrating auxiliary power sources to a power grid and/or to a load.

DETAILED DESCRIPTION

[0155] Referring initially to Figure 1 of the drawing, depicted therein is an example power supply system 20 constructed in accordance with, and

embodying, the principles of the present invention. The example power supply system 20 is operatively connected to at least one auxiliary power system 22, a utility power grid 24, and a load 26. The example power supply system 20 is further operatively connected to a communications system 30 comprising a remote status monitoring and control system 32, a communications system 34, and a network switch 36. The auxiliary power nodes 22, grid 24, load 26, remote status monitoring and control system 32, communications system 34, and network switch 36 are not necessarily part of the present invention and will be described herein only to that extent necessary for a complete understanding of the present invention.

[0156] The example power supply system 20 comprises at least one power control system 40, and each power control system 40 is operatively connected to at least one of the auxiliary power nodes 22. A power supply system of the present invention may have as few as a single power control system 40 or, theoretically, an unlimited number of the power control systems 40. The number of power control systems 40 is generally related to the number and type of auxiliary power nodes 22 supported by the example power supply system 20.

[0157] Figure 1 further illustrates that each of the example power control system(s) 40 comprises a power integration system 50, a power management board 52, a device control system 54, and a communications sub-system 56. In addition, each of the device control systems 54 comprises user interface hardware 58. [0158] Turning now to Figure 2 of the drawing, depicted therein are the details of the example power control system 40 that may be used as part of a power supply system of the present invention. The example power integration system 50 of the example power control system 40 defines a grid power connector 120, three auxiliary power connectors 122a, 122b, and 122c, and a load power connector 124. The example power control system 40 depicted in Figure 2 is thus capable of accommodating up to three of the auxiliary power sources 122.

[0159] The example power management board 52 of the example power control system 40 comprises first and second relays 130 and 132. The example device control system 54 of the example power control system 40 comprises a relay controller 140, a local controller 142, a data sub-system 144, and a local memory 146. The example local controller 142 is operatively connected to or incorporates the user interface hardware 58 of the example device control system 54. The example communications sub-system 56 of the example power control system 40 comprises an output controller 150, a data input connector 152, and a data output connector 154.

[0160] The example local controller 142 is or may comprise a processor configured to run software capable of performing the configuration, data collection, and operational logic described herein. One example of the local controller 142 may be a Linux system running one or more software daemons, with a master daemon controlling the overall operational logic of the power control system 40. The example local memory 146 is operatively connected to or forms a part of the local controller 142 such that data such as configuration data, operating parameters, and status data associated with the example device control system 54 can be stored by the local controller 142 in the local memory 146 and accessed through the communications sub-system 56 and/or user interface 58. [0161] Figure 4 illustrates a page layout overview of an example user interface 160 that may be used to set, access, and/or change configuration data, operating parameters, and status data associated with the example device control system(s) 54. In particular, the example local controller 142 is configured to display the user interface 160 using the user interface hardware 58 as will be described in further detail below. The example user interface 160 is configured to be implemented as a web site accessible, by referencing a uniform resource locator (URL), over a public internet protocol (IP) network, such as the Internet, or a private local area network (LAN). The example user interface 160 thus may be accessed by a remote computing device such as the remote status monitoring and control system 32. Remote access to the example user interface may thus be wired or wireless devices containing hardware allowing access to and interaction with the example user interface 160 through the communication network 34, network switch 36, and communications sub-system(s) 56.

[0162] The device controller 54 of each of the power control systems 40 is capable of generating the example user interface 160. When the power supply 20 comprises a single power control system 40, the device controller 54 of that power control system 40, referred to as a lone device controller 54, generates the example user interface 160. The lone device controller 54 allows entry of configuration data through the example user interface 160, stores the

configuration data, generates status data, and stores the status data. A local user with access to the example user interface hardware 58 associated with the lone device controller 54 or a remote user with access to the remote status monitoring and control system 32 can view and change configuration data and view status data through the user interface 160.

[0163] The power supply system 20 may comprises a plurality (two or more) of the power control systems 40. The power control systems 40 may be identical to each other, or some of the power control systems 40 may have only a subset of the features of one or more of the other power control systems. In the example power supply system 20, the power control systems 40 are identical to each other.

[0164] When the power supply system 20 comprises multiple power control systems 40, one of the power control systems 40 is identified as a master power control system 40 and the other power control system (s) 40 is/are identified as a slave power control system 40. In the case of multiple power control systems 40, the device controller 54 of the master power control system 40, referred to herein as the master device controller 54, generates the example user interface 160. The device controllers 54 of any slave power control system 40 are referred to herein as a slave device controller 54. The master device controller 54 allows entry of configuration data through the example user interface 160, stores the configuration data, generates status data, and stores the status data. A local user with access to the example user interface hardware 58 associated with the master device controller 54 or a remote user with access to the remote status monitoring and control system 32 can view and change configuration data and view status data through the user interface 160.

[0165] To facilitate proper coordination among power control systems 40 of a power supply system 20 comprising a plurality of the power control systems 40, the master device controller 54 allows entry and storage of what will be referred to herein as master configuration data. The master configuration data ensures the integrity of any configuration data necessary for proper coordination of any one or all of the multiple power control systems 40. The master device controller 54 further collects and stores what will be referred to herein as master status data and aggregate status data. Master status data includes any status data necessary for proper coordination among the plurality of power control systems 40. Aggregate status data includes data derived or calculated from at least some of the status data associated with a plurality of the power control systems 40. The master device controller 54 may further store local configuration data and at least a portion of any local status data associated with any slave power control system 40. The master device controller 54 thus maintains a copy of all configuration and status data necessary for operation of one or more of the power control systems 40 forming the power supply 20.

[0166] Slave device controllers 54 similarly are or contain computing devices capable of accessing the user interface 160 generated by the master device controller 54. Subject to security limitations (e.g., user levels and passwords), any slave device controller 54 may be used to view and alter at least some of the master configuration data, master status data, and aggregate status data, but the slave device controllers 54 do not need store master configuration data, master status data, and aggregate status data locally. While one or more slave device controllers 54 may locally store master configuration data, master status data, and aggregate status data, in the example power control system 40, any master configuration data, master status data, and aggregate status data locally stored by a slave device controller 54 is for backup or security purposes and is not used to coordinate the operation of the power control systems 40 during normal operation of the power supply system 20.

[0167] The slave device controllers 54 may store local configuration data and/or generate and store local status data. Local configuration data and local status data may be used to control operation of a particular slave power control system 40. Such local configuration data and local status data is typically not directly used to coordinate operation of the plurality of power control systems 40.

[0168] The master device controller 54 will generate aggregate status data by polling the local status data stored by any slave device controller(s) 54 and performing any required mathematical operations appropriate for generating such aggregate status data. The local status data associated with the master device controller 54 will typically be included in the aggregate status data.

[0169] As depicted in Figure 4, the example user interface 160 defines a home page 162, a system notification page(s) 164, and a global settings page(s) 166. The system notification page(s) 164 allows access to an alert page(s) 164a and a log page(s) 164b. The global settings page(s) 166 allows access to a login page(s) 166a, a system settings page(s) 166b, a regional settings page(s) 166c, a network settings page(s) 166d, a firmware settings page(s) 166e, a test page(s) 166f, and a regulatory page(s) 166g.

[0170] The web site page(s)s 164a and 164b correspond to or define web page(s) that allow access to alerts and logs, respectively, associated with warning or fault conditions to be viewed. The web site page(s)s 166a, 166b, 166c, 166d, and 166e correspond to or define web page(s) that allow the global settings associated with a particular power supply system 20 to be set. The test and regulatory page(s)s 166f and 166g correspond to or define web page(s) that allow entry and viewing of status data associated with testing functions and functions required by regulation, respectively.

[0171] The example user interface 160 further defines a solar system page(s) 170, a grid page(s) 172, a load page(s) 174, a battery system page(s) 176, a generator system page(s) 178, and a power control system page(s) 180. The solar system page(s) 170 further allows access to a solar status page(s) 170a and a solar configuration page(s) 170b. The grid page(s) 172 allows access to a grid status page(s) 172a and a grid configuration page(s) 172b. The load page(s) 174 allows access to a load status page(s) 174a and a load configuration page(s) 174b. The battery system page(s) 176 allows access to a battery status page(s) 176a and a battery configuration page(s) 176b. The generator page(s) 178 allows access to a generator status page(s) 178a and a generator configuration page(s) 178b. The power control system page(s) 180 allows access to a power control system status page(s) 180a and a power control system configuration page(s) 180b.

[0172] The status pages 170a, 172a, 174a, 176a, and 178a correspond to or define web page(s) that allow a user to view any status data associated with operation of and coordination among the auxiliary power system(s) 22 associated with each of the power supply system(s) 40. The configuration pages 170b, 172b, 174b, 176b, and 178b correspond to or define web page(s) that allow a user to enter and/or view any configuration data required for proper operation of and coordination among the auxiliary power system(s) 22 associated with each of the power supply system(s) 40. The status page(s) 180a and configuration page(s) 180b allow the user to view status data and view and/or alter

configuration data associated with each power control system 40.

[0173] Referring now to Figures 5A-D of the drawing, an example of a home page 220 that may be used as the example home page 162 will initially be described. The example home page 220 defines a main control region 222, a status region 224, a notification region 226, and a settings region 228. The example main control region 222 includes a main selection element 230, a power control element 232, a cabinet status element 234, and a plurality of system status elements 236. The example power status region 224 comprises a plurality of power status sub-regions 238. Each power status sub-region 238 comprises an identification section 240, a status section 242, and a data section 244.

[0174] The example home page 220 defines five of the power status sub- regions 238a, 238b, 238c, 238d, and 238e. In particular, the example sub-region 238a is associated with the first auxiliary power system 22a, the example sub- region 238b is associated with the grid 24, the example sub-region 238c is associated with the load 26, the example sub-region 238d is associated with the second auxiliary power system 22b, and the example sub-region 238e is associated with the third auxiliary power system 22c.

[0175] As shown by a comparison of Figures 5A and 5B, the example main selection element 230 is a dropdown box. When the user touches the arrow 230a of the example main selection element 230, the user is presented with three choices: a power supply system choice 230b, a power control system (1 ) choice 230c, and a power control system (2) choice 230d. The main selection element 230 thus allows the user to select the data to be displayed in the status region 224 of the home page 220. Selecting the power supply system choice 230b displays status data associated with the entire power supply system 20. Selecting the power supply system choice 230c displays status data associated with a first of two power control systems 40 as shown in Figure 5C, while selecting the power supply system choice 230d displays status data associated with a second of two power control systems 40 as shown in Figure 5C. The main selection element 230 thus allows the example home page 220 to be

reconfigured as necessary to view data associated with either of two power control systems 40 or aggregate data associated with the power supply system 20 incorporating the two power supply systems 40.

[0176] In the example home page 220, selecting (by clicking or touching) any of the power status sub-regions 238a, 238b, 238c, 238d, or 238e brings up the solar system page(s) 170, grid page(s) 172, load page(s) 174, battery system page(s) 176, generator system page(s) 178, or power control system page(s) 180 associated with the selected power status sub-regions 238a, 238b, 238c, 238d, or 238e. The solar system page(s) 170, grid page(s) 172, load page(s) 174, battery system page(s) 176, generator system page(s) 178, or power control system page(s) 180 allow selection of the status pages 170a, 172a, 174a, 176a, 178a, or 180a or the configuration pages 170b, 172b, 174b, 176b, 178b, or 180b. [0177] Figures 6A, 6B, and 6C depict a solar system page 240, a solar system configuration page 242, and a solar system status page 244,

respectively. The solar system page 240 defines a solar system configuration button 240a and a solar system status button 240b. The solar system

configuration page 242 displays first and second solar configuration data fields 242a and 242b that display and allow alteration of solar configuration data. The solar system status page 244 displays first and second solar status data fields 244a and 244b that display solar system status data. Solar status data may be alpha-numeric, graphical, icons, or combinations thereof.

[0178] Figures 7A, 7B, and 7C depict a grid page 250, a grid configuration page 252, and a grid status page 254, respectively. The grid page 250 defines a grid configuration button 250a and a grid status button 250b. The grid configuration page 252 displays first and second grid configuration data fields 252a and 252b that display and allow alteration of grid configuration data. The grid status page 254 displays first and second grid status data fields 254a and 254b that display grid status data. Grid status data may be alpha-numeric, graphical, icons, or combinations thereof.

[0179] Figures 8A, 8B, and 8C depict a load page 260, a load configuration page 262, and a load status page 264, respectively. The load page 260 defines a load configuration button 260a and a load status button 260b. The load configuration page 262 displays first and second load configuration data fields 262a and 262b that display and allow alteration of load configuration data. The load status page 264 displays first and second load status data fields 264a and 264b that display load status data. Load status data may be alpha-numeric, graphical, icons, or combinations thereof.

[0180] Figures 9A, 9B, and 9C depict a battery system page 270, a battery system configuration page 272, and a battery system status page 274, respectively. The battery system page 270 defines a battery system

configuration button 270a and a battery system status button 270b. The battery system configuration page 272 displays first and second battery system

configuration data fields 272a and 272b that display and allow alteration of battery system configuration data. The battery system status page 274 displays first and second battery system status data fields 274a and 274b that display battery system status data. Battery system status data may be alpha-numeric, graphical, icons, or combinations thereof.

[0181] Figures 10A, 10B, and 10C depict a generator system page 280, a generator system configuration page 282, and a generator system status page 284, respectively. The generator system page 280 defines a generator system configuration button 280a and a generator system status button 280b. The generator system configuration page 282 displays first and second generator system configuration data fields 282a and 282b that display and allow alteration of generator system configuration data. The generator system status page 284 displays first and second generator system status data fields 284a and 284b that display generator system status data. Generator system status data may be alpha-numeric, graphical, icons, or combinations thereof.

[0182] With the foregoing general understanding of the present invention in mind, details of example implementation of the example power supply system 20, the power control system(s) 40, the power integration system(s) 50, and the user interface 160 will now be described in further detail.

[0183] As generally discussed above, the example power supply system 20 depicted in Figure 1 may comprise one or more of the power control systems 40, and suffixes " and "n" are used in Figure 1 in connection with the reference characters "40", "50", "52", "54", "56", and "58" to identify individual examples of the same type of element. Further, each of the power control system 40 may be connected to one or more of the auxiliary power nodes 22, and the suffixes (1 -a), (1 -b), (1 -n) are used in Figure 1 to represent the auxiliary power supplies 22 associated with the power control system 40-1 and the suffixes (N-a), (N-b), and (N-n) are used in Figure 1 to represent the auxiliary power supplies 22

associated with the power control system 40-N. The limitation on the number of power control systems 40 associated with each power supply 20 and/or auxiliary power nodes 22 associated with each power control system 40 is, theoretically, unlimited, but practical considerations may effective limit either of these elements 40 or 22 to a predetermined number of at least 1 . In the example depicted in Figures 1 -3, the example power control system 40 may be associated with up to five of the auxiliary power nodes 22.

[0184] As shown in Figures 2 and 3, each power integration system 50 defines a plurality of power nodes 22 and is configured to operate in at least one operating mode. In at least one operating mode, at least one input power signal is input to the power integration system 50 through at least one power node 22. For any given power integration system 50, the input power signal may be a utility power signal from the grid 24 or an auxiliary power signal from the auxiliary power system 22 associated with the given power integration system 50.

Further, each power integration system 50 generates an output power signal based on one or more input power signals. The output power signal may be applied to the grid 24, to the load 26, and/or to an energy storage device forming the auxiliary power system 22 associated with that given power integration system 50.

[0185] In a power supply system 20 comprising a single auxiliary power system 22 and a single power control system 40 that is not connected to the remote status monitoring and control system 32, the operating mode of the power integration system 50 may be controlled completely within the power control system 40 using the power integration system 50, the power management board 52, the device control system 54, and the user interface 58. Accordingly, when a single power control system 40 is present, that power control system 40 is capable of operating in a stand-alone manner. In this context, the device control system 54 stores parameters that are used by the power control system 40 operating in the stand-alone mode.

[0186] In a power supply system 20 comprising multiple auxiliary power nodes 22 and multiple power control systems 40, the mode in which the plurality (two or more) power integration systems 50 operate is coordinated among the plurality of power control systems 40 using the power management boards 52, the device control systems 54, and the communications sub-systems 56 of the plurality of power control system 50. When multiple power control systems 40 are present as shown in the example power supply system 20, the operation of those power control systems 40 is coordinated using the communications sub-systems 56. In this scenario, one of the power control systems 40 will be identified as a master power control system as generally described above, and the remaining power control systems 40 are identified as slave power control systems. The master power control system 40, and in the example power control system 40 the master device control system 54 associated therewith, will control at least some functions of the slave power control systems 40.

[0187] The example communications sub-system 56 allows communication among the master and slave power control systems 40 and, optionally, between any given power control systems 40 and the local status monitoring and control system 28 and/or the remote status monitoring and control system 32. The example communications sub-system 56 is configured to communicate status monitoring and control data with the power integration system 50 and device control data with the device control system 54. The status monitoring and control data is used to perform routine, non-time critical functions such as determining status of the power integration system 50 and any auxiliary power system 22 associated therewith. The device control data is used to perform time critical functions such as coordinating operating mode changes among the plurality of power control systems 40.

[0188] The example power supply system 20 thus facilitates the integration of auxiliary power nodes 22 to define a power system configuration appropriate for the particular configuration of hardware forming the example power supply system 20. Further, the exact nature of the hardware selected to form the example power supply system 20 need not be known in advance.

[0189] Figure 2 shows that the example communications sub-system 56 further comprises a cable assembly 320 that extends between the data input connector 152 and the data output connector 154. The example cable assembly 320 comprises a first conductor pair 322, a second conductor pair 324, a third conductor pair 326, and a fourth conductor pair 328. The first and second conductor pairs 322 and 324 are connected to the data sub-system 144 of the device control system 54. In the example communications sub-system 56, the first and second conductor pairs 322 and 324 form transmit and receive cables of an ethernet based communications system, but other standard or non-standard communications systems may be used in addition to or instead of an ethernet based communications system. The third conductor pair 326 is further operatively connected to the relay controller 140. The fourth conductor pair 328 is further operatively connected directly to the local controller 142.

[0190] The communications system implemented using the first and second data pairs 322 and 324 is capable of transmitting status monitoring and control information, and in particular is capable of data associated with non-time critical functions carried out by the power control system 40. The third and fourth conductor pairs 326 and 328 carry device control data used for time critical functions carried out by the power control system 40. The third and fourth conductor pairs 326 and 328 thus allow time critical functions to be coordinated and implemented in real time or near real time.

[0191] The output controller 150 controls the output switch array 156 to connect the data output connector 154 to or disconnect the data output connector 154 from the data sub-system 144, the relay controller 140, the local controller 142, and the data input connector 152. In particular, when the local controller 142 determines that the output data connector 154 of a given power control system 40 is connected to the input data connector 152 of another of plurality of power control systems 40, the output switch array 156 is configured to be in a closed configuration. When a given power control system 40 is the only power control system 40 of the power supply system 30 or is the last power control system 40 of a plurality of power control systems 40, the output controller 150 is controlled to open the switches forming the switch array 156 to disconnect the data output connector 154 from the data sub-system 144, the relay controller 140, the local controller 142, and the data input connector 152. When the output data connector 154 of a given power control system 40 is connected to the input data connector 152 of another of a plurality of power control systems 40 forming the power supply system 30, data may be carried between any of the plurality of control systems 40.

[0192] Turning now to Figure 3 of the drawing, an example power integration system 50 that may be used by the example power control system 40 will now be described in further detail. The example power integration system 50 depicted in Figure 3 comprises an inverter 420, a DC bus 422, an AC bus 424, a first DC/DC converter 426, and a second DC/DC converter 428. The example power integration system 50 depicted in Figure 3 forms a part of an example power control system 40 that supports first and second DC auxiliary power nodes 22a and 22b and an AC auxiliary power source 22c. The example first DC auxiliary power source 22a is formed by a battery 430, the example second DC auxiliary power source 22b is formed by a photovoltaic array 432, and the example AC auxiliary power source 22c is formed by a generator 434.

[0193] The inverter 420 is operatively connected between the DC bus 422 and the AC bus 424. The first DC/DC converter 426 is operatively connected between the battery 430 and the DC bus 422. The second DC/DC converter 428 is operatively connected between the PV array 432 and the DC bus 422.

[0194] The example power integration system 50 additionally comprises a first mode control switch 440, a second mode control switch 442, and a third mode control switch 444. The first mode control switch 440 is connected between the inverter 420 and the AC bus 424. The relays forming a part of the power management board 52 form the second mode control switch 442. The third mode control switch 444 is connected between the generator 434 and the AC bus 424.

[0195] The local controller 142 of the example power supply system 40 depicted in Figure 3 is operatively connected to the inverter 420, the DC bus 422, and the AC bus 424 to sense a status of the inverter 420 and voltages on the buses 422 and 424. The example local controller 142 is further arranged to control operation of the inverter 420 and mode control switches 440, 442, and 444 to control the operating mode of the power supply system 40 and power integration system 50 forming a part thereof.

[0196] The example integration system 50 may be configured to handle up to three of the auxiliary power nodes 22a, 22b, and 22c as shown in Figure 3.

However, the integration system 50 may integrate any one or any combination of two of the auxiliary power nodes 22a, 22b, and 22c. [0197] In any configuration, the local controller 142 is capable of sensing a DC voltage on the DC bus 422 and an AC voltage on the AC bus 424. Voltage data representing these DC and AC voltages can be stored in the local memory 146 and used for control of the example integration system 50. This voltage data, along with data representing other status information such as the state of the first, second, and third mode control switches 440, 442, and 444 (e.g., power management switches 130 and 132), can also be stored in the local memory 146 by the local controller 142 as status data. Such status data can be later downloaded from local memory 146 through the local controller 142 and/or transmitted to the local status monitoring and control system 28 and/or the remote status monitoring control system 32 if the example power supply system 20 is connected to the communications system 30 as depicted in Figure 1 . In particular, any of the configuration data or status data stored by the local controller 142 can be accessed, altered, and/or viewed using the user interface 160 running accessible to any of the local controllers 142 or the remote status monitoring and control system 32 as generally described above.

[0198] The example local controller 142 may be configured such that the local controller 142 controls the PMB controller 140, the inverter 420, and the mode control switches 440, 442, and 444 such that the integration system 50 changes operating modes in a timely and coordinated fashion within the context of the overall power supply system 20.

[0199] Additionally, if the local controller 142 of the master power control system 40 determines that the utility power signal on the AC bus 424 thereof is outside of predetermined parameters, the local controller 142 of that master power control system 40 directs the PMB controllers 140 and local controllers 142 of any slave power control systems 40 to direct the local controllers 142 of those slave power control systems 40 to switch to an operating mode in which the AC power signal is generated by one or more of the auxiliary power nodes 22. This switch over may be accomplished by, for example, communicating zero-crossing information such that the change from utility mode to standby mode is coordinated among the various power control systems 40. The local controller 142 of the master power control system 40 of any given power supply system 20 thus is capable of communicating directly and in real time, or relatively directly and in near real time, through the dedicated third and fourth conductor pairs 326 and 328 rather than using the data sub-system 144. Accordingly, operation of the example power supply system 20 is not adversely affected by any delays introduced by the communications system used to implement that data sub-system 144.

[0200] The example user interface hardware 58 may be any appropriate hardware, such as a touch screen, display screen, keyboard, mouse, or the like, for communicating information to and receiving information from a user. In this context, the local status monitoring and control system 28 will further define or define a user interface system that allows users with physical access to the example power supply system 20 to control (e.g., configure) and/or monitor the status of the power supply system 20 and any power control systems 40 forming a part thereof, any auxiliary power nodes 22 connected thereto, and any grid 24 and/or load 26 to which the power supply system 20 is connected.

[0201] The remote status monitoring and control system 32 may be used to facilitate configuration of the example power supply system 20 and of the power control systems 40 forming a part thereof from a remote location and/or from a portable device that is not physically connected to the example power supply system 20 such as a smart phone or tablet. The remote status monitoring and control system 32 will typically comprise or be connected to a user interface device (not shown) such as a touch screen, display screen, keyboard, mouse, or the like. In this context, the remote status monitoring and control system 32 will further define or define a user interface system that allows users without physical access to the example power supply system 20 to control (e.g., configure) and/or monitor the status of the power supply system 20 and any power control systems 40 forming a part thereof, any auxiliary power nodes 22 connected thereto, and any grid 24 and/or load 26 to which the power supply system 20 is connected. The remote status monitoring and control system 32 may provide the same, greater, or lesser functionality to the user than the local status monitoring and control system 28 depending on factors such as user identity, safety, privacy, and security.

[0202] The operating modes of any individual power integration system 50, any individual power control system 40, or the power supply system 20 in its entirety will depend on factors such as the specifics of the hardware forming a given power supply system 20 and/or parameters determined by the local status monitoring and control system 28 and/or remote status monitoring and control system 32. For example, the status monitoring and control systems 28 or 32 may be configured to alter the operating mode of any one or more power control systems 40 forming the power control system 20 based on the market price of electrical power at a particular point in time. For example, the power supply system 20 may be configured to sell power, including stored power, back to the electrical power utility when the spot price is high and to purchase power from the electrical power utility when the spot price is low. As another example, when the spot price of electrical power is high, the power supply system 20 may be configured to use generated and/or stored power rather than purchase electrical power so long as possible. As yet another example, the power supply system 20 may be configured to store power when the spot price is low and sell the stored power to the utility only after the spot price increases.

[0203] A power supply system 20 of the present invention can easily be configured to switch among any such modes as allowed by the specific hardware configuration defined by a particular implementation of that particular power supply system 20.

[0204] Turning now to Figures 1 1 -128, a detailed example of a detailed example of the user interface system 160 will now be described.

A. USER PROFILES AND USER GOALS

[0205] This section describes the various types of users of the power control system 20 and how the example user interface system 160 may be configured to allow appropriate access to the configuration and/or operating parameters of the power control system 20. The example user interface 160 may be referred to below as "Ul" or "the Ul". The term "SkyBox" may be used below to refer to a power control system 40 of a power supply of the present invention.

[0206] Typically, the power control system 20 has the following types of user profiles: Public; Owner; Installer; and Administrator. Each user profile, apart from Public, has an associated password. Additionally, users of the power supply system 20 typically operate in one of the following environments: Residential installation (e.g., homeowner has system installed on house); commercial installation; and/or microgrid.

[0207] Each Profile on the system has a defined set of permissions. A List of Possible User Profile Permissions that an account can have is set forth below. For each secondary item in the list, the selection is mutually exclusive. Account authentication should be designed in such a way that the permissions associated with a particular user profile may be changed.

[0208] List of Possible User Profile Permissions: Status:

o Read Only: Can view all status information.

Action Buttons:

o Limited:

^■ Start Generator

Remote Login is intended to provide increased security specifically for systems that allow access of the Ul through a local area network or wireless network. The following Remote Login Method provides a method to authenticate users connecting via remote methods. [0212] Remote Login Method:

1 . An Owner, Installer, or Administrator user profile can decide to

enable remote login user security, and if enabled assign a unique remote login password.

a. Remote login password are suggested to follow the

recommendation displayed in the Information Dialog Remote Password Advisory message.

2. If enabled, a public remote user would be required to login using the remote login password before they could go to the home screen.

a. Once logged in, they would have same profiles and

responsibilities we share today for public users (including the ability to further log in as Owner, Installer, or Administrator). b. Remote login would time out according to the Security

lockout timer during periods of inactivity.

c. Remote login would also end upon closing the browser

window.

3. Remote Login can be enabled/disabled through the Global settings.

4. The Remote login password can also be viewed and changed

through the Global settings.

5. Profiles and permission remain the same for the public user defined in section 3.1 .

B. GENERAL PRINCIPLES OF EXAMPLE USER INTERFACE 160

[0213] As generally described above, the example user interface 160 can be accessed from multiple devices including: GUI touchscreen on power control system 40 (e.g., small resistive touch LCD); mobile phone/tablet connected using the communications system 30, or computer using the communications system 30.

[0214] To enhance user comfort, the example user interface 160 should comprise standard user interface elements such as buttons (active or disabled), text labels, data fields, touchscreen keyboard, scroll arrows, and the like. The example user interface system 160 further operates in one of a view mode, an edit mode, and a user input mode. View mode is the standard mode. While in View mode a user can only observe values, but cannot change them. In Edit mode, the user can edit values by interacting with various Ul input elements.

[0215] When in View Mode input elements like text boxes, dropdowns, and toggle switches should not be visible. Only the value should be shown. When in Edit mode fields should have the appropriate input element around them indicating that they can be changed. For regular fields this is a text box; for a dropdown field it's a dropdown selection; for a binary choice toggle it's a button with a slider. In the example user interface 160, the user must press 'Edit' before being allowed to change any fields by entering Edit Mode.

[0216] Logic flow when changing between View and Edit modes will proceed as follows:

1 . Navigate to screen with editable fields. User is in View Mode and cannot change values.

2. An edit button will appear at the top of the screen.

[0217] These requirements do not apply to the Wizard, which by design requires user input and should be presented entirely in Edit Mode. Examples of screens provided herein are intended to show screen content and layout only. They are not intended to document the View Mode to Edit Mode process unless otherwise stated.

C. DETAILED DESCRIPTION OF EXAMPLE USER INTERFACE 160

[0218] This section defines detailed user interface designs for an example configured for a generic power control system 40, and any specific variable values, minimum, maximum, or range is for illustrative purposes only.

[0219] The example user interface uses what is referred to herein as a "base screen" as a container for more complicated Ul elements with which a user may interact. A base screen can present one screen from a page at a time. Much like sliding a magnifying glass or viewport over a piece of paper, each screen has a fixed width and height, but a page can be made up of any number of screens. In general, a user navigates between pages by following links and between screens by scrolling up and down.

[0220] The example user interface 160 employs the following types of user interface elements: buttons, numeric/text input, password input, dropdown input, toggle input, multiple choice, dialog boxes and pop-ups, toasts, information dialog, warning dialog, error dialog, fault dialog, help tool-tips, page layout overviews, screen templates, and the like.

1 . Home Screen

[0221] As generally discussed above, the example user interface 160 described herein employs a home screen as shown in Figure 1 1 . The example home screen of Figure 1 1 provides a high-level overview of major system components and serves as the top-level page for the navigation structure of the user interface 160.

[0222] To provide meaningful information "at a glance", as shown in the drawing Figure 1 1 , the home screen employs the following color scheme to indicate status information: Green - system or component is in use and functioning normally; Black - system or component is turned off and awaiting manual activation; Gray - system or component is not available or not present; Yellow - system or component is operating in an alternate mode or state from that denoted by green; Red - system or component is returning a fault and cannot be activated until the fault is corrected.

[0223] The example home screen depicted in Figure 1 1 comprises six major groups of functionality. The most prominent group contains the five status tiles for each system component. The next largest group contains the icon status area and the SkyBox selection dropdown. The SkyBox power button on the left and inverter button on the right make up the last part of the white upper tile. Finally, the global settings button and notification button are on the upper right and upper left parts of the screen respectively.

^■ Fault State: Red color, when you push the button SkyBox will attempt to clear all present faults and restart. If successful at clearing the faults and restarting, the button will change to the ON state.

^■ Disabled State: Grey color, pushing the button has no effect.

This happens when the system controller determines that the system is in limbo mode because of various software or hardware communication issues. Details about the failure should be available in the alerts & logs screen. Service by a technician may be required to restore operation.

2. User Login

[0236] If a user attempts to access a setting or screen which requires permissions not granted to their current active profile, they should be given the opportunity to log in to the appropriate profile which has those permissions. This screen allows a user to login to a different profile with appropriate permissions so they can access restricted components. The login screen will only appear if access to particular components of the system has been restricted.

[0237] The user login screen of the example user interface system of Figure 1 1 has two screens. A Profile Selection Screen as shown in Figure 16, and a Login Screen as shown in Figure 17. If a user is already logged in, but they do not have permission to access a particular feature, the login screen will appear. The only active options will be ones that have permission to perform that action. The other options will not be shown.

[0238] Depicted in Figure 18 is an Automated User Login Scenario: Solar Status. A user using the Public Profile navigates to Solar Status by tapping the Solar Tile on the Home Screen. At the top of the screen, a Configure button is displayed on the Navigation Bar. When pressed, the Configure button will change pages to the Solar Configuration screen. When the user attempts to enter Edit Mode by pressing the Edit button they will be shown a login screen, allowing them to select the appropriate profile and login as required as described above. Once the password is entered successfully, the user is logged in to their chosen profile and moved to the page they were trying to access in Edit Mode.

[0239] Only one user is allowed to edit configuration at a time - subsequent users should be notified that the requested fields are not available for the moment while the first is editing. Resolution of multiple users may be resolved as follows.

1 . Edit mode is entered by pressing the "Edit" or "Configure" button that appears in the upper banner of the screen.

2. If one user is currently in Edit mode, the Edit/Configure buttons on all other active sessions shall change to read "In Use" 3. At a minimum, Ul should allow only one user to be in an edit mode at a time. However, if it is possible it would be preferred if the Ul could allow multiple concurrent sessions to be in edit mode, as long as they are in separate areas. In other words, one user could be allowed to make changes in the Battery tab if another user is making changes in the Grid tab.

4. If multiple users attempt to enter edit mode simultaneously, the users shall be prioritized in the following order:

1 . Physical device

2. Another Skybox connected on the same LAN

3. A computer or device connected on the same LAN

4. SunSpec

5. Optics

3. Setup Wizard

[0240] The example user interface 160 implemented by the example power control system 40 may employ a Setup Wizard may function as follows.

• The first time the wizard is run, the user has Administrator privileges

without having to ask for them to log in. They are automatically an

Administrator as long as they remain in the Wizard.

• If the wizard is run again, the user must log in at the Installer level or

above, before they are allowed to go through the questions.

• If the user runs through the Wizard as an Installer, they cannot change the password for the Administrator account. Users can only change

passwords for their own level or lower levels.

• Owner level does not have permission to run the Wizard.

[0241] The Setup Wizard will identify the language preferred by the user and allow the user to load existing settings saved during a previous session using a USB drive. If the user does not have access to existing settings, the user is then prompted by the Setup Wizard to set Display Settings, Internet Settings (if available), and verify whether a firmware update may be required and a USB drive with a valid update package has been inserted into the system. The Setup Wizard then allows the user to input Regional Settings.

[0242] The Setup Wizard next allows the user to identify which components have been connected to the power control system(s) 40 as shown in Figure 19. In Figure 19, all selections are active by default (green with white lines) when the screen first loads. When an item is selected, the fill color turns grey and the icon lines become black. If an item is inactive when the user proceeds to the next screen, the questions relating to that entire section are skipped. If an item is active, then the questions for that section are shown. The user cannot proceed to the next screen unless at least two items are active.

[0243] An example of Setup Wizard configuration pages allowing the configuration of the power control system 40 for a particular solar system is depicted in Figures 20, 21 , and 22. The details of the function of the solar system configuration web pages depicted in Figures 20-22 will be explained in further detail below.

[0244] An example of Setup Wizard configuration pages allowing the configuration of the power control system 40 for a particular grid environment is depicted in Figures 23-33.

[0245] Figure 23 allows the user to define the nature of the grid connection and operates as follows.

1 . Operation:

• Only one of the four buttons may be enabled at a time.

• One of the four must be selected if they have grid. • "Non export" should be default.

• If user selects a new button, the previously selected option should be deselected.

A. Net metering with backup:

• Description: This selection maximizes energy harvest, has

unrestrained selling of power to the utility, and batteries are primarily reserved for backup.

• Behavior: PV is harvested and provided to loads and sold to the utility. Batteries are primarily reserved for backup. If the cost of utility energy varies, the batteries may be discharged during time periods where the cost of utility power is greater than the cost of battery power.

B. Self consumption:

• Description: This selection minimizes use of grid energy but excess generation is allowed to be sold to the utility in preference to going open-circuit. This application is typically used in regions where the cost of utility power is greater than the reimbursed rate for energy sold.

i. If selected, display a follow-on screen (figure 28) with these inputs:

• GridZero™ max threshold (kW)

• Minimum reserve (%SOC)

• Behavior: Skybox operates in parallel with grid, and will modulate output to displace grid power wherever possible with battery and PV power, up to the GridZero max threshold and down to the Minimum reserve (%SOC). Batteries are cycled. Once batteries are recharged and if all loads are met, Sky Box may export excess energy.

C. Non export • Description: This selection maximizes Self supply, but power is not allowed to be exported;

i. If selected, display a follow-on screen (figure 28) with these inputs:

• GridZero™ max threshold (kW)

• Minimum reserve (%SOC)

• Behavior: SkyBox operates in parallel with grid, and will modulate output to displace grid power wherever possible with battery and PV power, up to the GridZero max threshold and down to the Minimum reserve (%SOC). Once batteries are recharged and all loads are met, the array may be open circuited to prevent excess generation.

D. Maximum independence:

• Description: This selection maximizes Independence.

• Behavior: Skybox attempts to remain off-grid wherever possible. If the system is overtaxed or battery is depleted, Skybox will connect to grid and/or generator, transfer loads over to the AC source and recharge batteries from allowed sources. This mode does not export power to grid.

[0246] Figure 24 illustrates a Setup Wizard screen that allows the user to set max threshold and minimum reserve (% SOC) for the power control system 40.

1 . Attribute label: GridZero™ max threshold (kW):

• Description: sets the boundary thresholds for GridZero™ operation to offset grid consumption

• Behavior: If user selects either Self consumption or Non export as grid use, then present this screen

2. Minimum reserve (%SOC)

• Description:— • Default: 50%

[0247] Figure 25 allows the user to identify whether the cost of energy varies throughout the day. If yes, the system displays a schedule screen as shown in Figure 27. If no, the system displays a flat rate screen as shown in Figure 28.

[0248] The example Time of Use Schedule screen of Figure 27 functions as follows.

a. There are two modes of behavior "View Mode" and "Edit Mode". i. View Mode: The user has access to the options "Add" and "Delete" and can use the arrow keys to navigate between Time of Use schedules. The user can edit the four fields by selecting them. The user is in View Mode as long as the form is pristine and none of the fields have been edited. ii. Edit Mode: The user enters Edit Mode by changing an

existing field, or adding a new schedule entry. The user has access to the options "Apply" and "Cancel". The user cannot use the arrow buttons to navigate between schedule entries. The user must save their changes by pressing "Apply" or discard them by pressing "Cancel".

1 . If the user attempts to exit the ToU schedule wizard, and they have unsaved changes, a warning dialog box should appear stating "Do you want to discard unsaved changes?", with two options "Yes" and "No". Selecting "No" will return the user to the schedule screen. Selecting "Yes" will exit the user from the ToU entry wizard.

b. If no schedule entries exist, the user is in view mode and the only available option is "Add". Attribute Label 1 : Begin date

a. Description: User input to set the beginning date of a rate schedule time block. The rate schedule time block is ended by the beginning of the next time block.

• If the schedule was a new schedule created with the "Add" button, then SkyBox should return to the previous record in View Mode if one exists.

• If an existing schedule was being edited, those changes should be discarded and the user should be returned to View Mode for the schedule they are viewing.

[0249] In Figure 28, the user enters a flat rate for cost of energy. When the value of Rate is greater than the value of the Battery $/kWh (IE, grid power is more expensive than battery power), the system may give preference to self supply (GridZero™), powering loads from PV and battery up to the GridZero™ max threshold (kW) and down to the Minimum reserve (%SOC). When the value of Rate is less than or equal the value of the battery $/kWh, Skybox shall give preference to Selling excess PV production.

[0250] Figures 29 and 30 illustrate Demand charge reduction screens. Figure 29 allows the user to determine whether demand charges apply to maximum kW peaks. If yes, the batteries may be discharged to support loads that exceed a given threshold in order to reduce utility demand charges. If Yes is selected in Figure 29, a follow-on screen is displayed allowing the user to set a Grid support threshold value (kW) as shown in Figure 30.

[0251] Figures 31 and 32 depict Grid Connection Demand Cap screens that may be displayed by the Setup Wizard. In Figure 31 , the user is allowed to enable external CT, and, if external CT is enabled, Figure 32 allows the user to enter CT settings.

[0252] Figure 33 illustrates a Grid Interconnection Profile that allows the user to select a grid interconnection profile such as IEEE 1547, HEC01 , HEC02, CA Rule 21 , AS4777, and VDE410. Any selection made here should be mapped to the configuration screen. Selecting a standard should auto populate the grid interconnection fields with the associated default value

[0253] Figures 34-38 illustrate user interface screens that allow the user to configure the interaction of the power control system 40 with the load 26. The page depicted in Figure 34 is displayed only if a generator is not selected. If no generator is connected to the power control system 40, the output node 22 normally associated with a generator is reassigned to be a controllable load output. In particular, the fifth power node or electrical connection of the example power control system 40 can be reassigned to be an output which can be energized or de-energized independently of the primary output. In this case, Figure 34 allows the user to use the generator connection as a separate, controllable output. If the user answers Yes, the generator tile on the home screen is changed to represent a controllable load and to display load oriented settings in status and configuration.

[0254] Accordingly, Figures 35 and 36 are displayed only if the generator connection is used as an output. Figure 35 determines when the output defined by the generator connection is used to supply power to the loads connected thereto, and, if a timed schedule is selected, Figure 36 allows the user to determine the load operating schedule.

[0255] If the generator connection is not used as an output and a generator is connected thereto, the load configuration pages depicted in Figures 37 and 38 are displayed to the user. Figure 37 allows the user to enable load management battery runtime, while Figure 38 allows the user to define how to implement load management battery protection.

[0256] Figures 39-48 illustrate screens displayed by the Setup Wizard to allow configuration of the power control system 40 for a particular battery system connected thereto. The details of the function of the battery system configuration web pages depicted in Figures 39-48 will be explained in further detail below.

[0257] Figures 49-55 illustrate screens displayed by the Setup Wizard to allow configuration of the power control system for a particular generator system connected thereto.

[0258] In the example web page depicted in Figure 49, all selections are enabled by default, with the exception of "This generator is manual start".

Multiple selections are allowed. If "manual start" is selected, all other selected items are cleared. If "manual start" is selected and another item is selected, manual start is cleared (ie, system can either be manual start or any and all of the automatic start options, but not both). Active checkbox items should have a green background to indicate that they are "ON".

[0259] The following list explains the effect of selection of each item depicted in Figure 49:

1 . If the battery is discharged too low = ags_start_on_soc_enabled is true.

2. If the load is too high = ags_start_on_load_enabled is true.

3. Exercise = ags_exercise_enabled is true.

4. There are quiet times when this generator should not run =

ags_quiet_enabled is true.

5. If any of the above options are selected ags_enabled is also set to true. 6. If This generator is manual start is selected ags_enabled,

ags_start_on_soc_enabled, ags_start_on_load_enabled,

ags_quiet_enabled, ags_exercise_enabled are all set to false.

[0260] The details of the function of the generator configuration web pages depicted in Figures 50-55 will be explained in further detail below.

4. System Notification

[0261] Example system notification web pages will now be described with reference to Figures 56 and 57.

[0262] The system notification alerts page depicted in Figure 56 is accessed by pressing the notification icon in the top left corner of the home screen. It contains two tabs: Alerts, and Logs. The button next to the tab name shows a number which indicates the amount of unread notifications in that tab. The Alerts tab is selected in Figure 56

[0263] If the user clicks on this number, a dialog box will appear asking them if they would like to mark all notifications as read. The user also has the ability to mark individual messages as being read by clicking on them. If user is logged in as Public profile, the login prompt shall be provided if they click either unread notifications number. The system may configure such that only certain user profiles are allowed to mark messages as read.

[0264] When the Log tab is selected, a log of system notifications is displayed as shown in Figure 57.

5. System Status [0265] Example system status web pages indicating the status of the power supply system 20 and/or power control system(s) 40 forming a part thereof (referred to in the drawing as SkyBox) will now be described with reference to Figures 58-62.

[0266] The web page depicted in Figure 58 contains various graphs related to overall system usage by all major components of the power supply system 20, power control system(s) 40, and/or any auxiliary power nodes 22 operatively connected thereto.
