BACKGROUND OF THE INVENTION

[0002] 1 ) Field of the System

[0003] This invention is directed to a modular solar power array providing for swappable portable power units, solar generators and existing circuit integrations.

[0004] 2) Description of the Related Art

[0005] With the renewed effort to provide renewable energy, there has been much research into solar cells. Much progress has been made in increasing the efficiency of solar cells and decreasing the cost of production. With these

improvements, there is an increasing use of solar cells for converting solar energy to electrical energy. However, there is much improvement needed to apply this power to multiple settings.

[0006] Solar power is a clean form of energy that’s natural, renewable, and free. Using a transportable solar system allows you to deliver power to remote locations without sacrificing electrical items such as emergency equipment, fridges, lights, mobile devices and more. Additionally, eliminating the need for a generator removes the need for fuel, noise and significantly reduces costs. There have been attempts to provide for portable and transportable power supplies, but none of these attempts include the ability to have a base charge for sustained charging of a load, a set of portable power units that, when combined, provide aggregated power with removable portable power units from the set for deployed power supplies. These attempts include United States Patents

5522943, 5969501 and 8203237 as well as United States Patent Application

Publications 20050093514, 20080029153, 20090127933, 201 10176256, 20120187761 , 20120202094 and 20120205975.

[0007] It has been reported that when a natural disaster occurs, electricity is typically the first important service to be lost, which can have a devastating impact for days, weeks, or even months. Without electricity, many of our most basic needs go unfulfilled (e.g. power for homes, hospitals, food storage, heating) and emergency response teams can’t offer proper assistance. Traditional generators are used but suffer from the need to use fuel which isn’t readily available as fuel vehicles cannot transport fuel to the areas in timely fashion. Additionally, communication systems cease operations making relief and assistance even more challenging.

[0008] It is therefore an object of the present system to provide for a modular system for providing power using a base power storage, portable power units, solar power input, capacitors and AC and/or DC output.

[0009] It is another object of the present system to provide power using a mobile platform to deploy power to remote locations or when power is unavailable such as with natural disasters.

DETAILED DESCRIPTION

[0027] With reference to the drawings, the system will now be described in more detail. Referring to Figure 1 , a solar power source such as a solar array 10 that can be one or more solar panels providing electrical energy. The solar panels of the solar array can be affixed to a structure such as a building roof, stand alone or portable. The solar array can be attached to a controller 12 that can transform the energy provided by the solar array to different voltage. For example, the solar array can convert produced 12- volt power to 48-volts. The solar power controller can be connected to a DC to AC converter 14 providing for the energy provided from the solar array to be converted into an alternating current. The DC to AC converter can be connected to a power input switch 16. The power input switch can be attached to an external power source such as AC source 18. The external power source can be the traditional electrical grid. The power input switch can include a power input controller that can be configured to allow power from the DC to AC converter, external power source or a combination thereof, to pass through to input power bus 20.

[0028] Portable power unit 21 can be connected to the power in bus to receive power from input power bus 20, which can charge the portable power unit. An example of a portable power unit is shown in United States Patents 9,865,903 and 10084213 and United States Application 16/1 10,947 incorporated by reference. Multiple secondary portable power units 22a through 22d can also be attached to input power bus 20 to receive power. Reserve portable power unit 24a through 24c can also be attached to input power bus 20. The portable power units can be attached to the power in bus so that portable power unit 21 is first in line in the circuit and therefore would have the least amount of resistance on the power in bus. The portable power unit with the least amount of resistance can be designated the primary portable power unit.

[0029] The portable power units can include communication ports allowing data communications between the portable power units over data network 26 which can include data hub 28. The data network can also include transceivers included in the portable power units and wireless communications between the portable power units. The portable power units can be hot swappable on and off the power bus. When removed, the portable power unit can separately be attached to an external power source such as solar panels, AC power, DC power, battery, generator and the like. A shelf or other support unit can be used to support the portable power units and can include electrical contacts which engage with electrical contacts on the portable power unit when the portable power unit is placed on the storage unit, the storage unit contacts engage with the portable power supply contacts and provide power to the portable power unit. Therefore, a portable power unit can be removed from the power in bus and used to provide power to a location remote from the power in bus. The storage unit can include a storage unit controller configured to determine the primary portable power unit, detect the presence of a portable power unit on contacts, activate the contacts when a portable power unit is present or any combination. The storage unit controller can be in communications with the portable power units and the power input switch. The storage unit controller and the power input switch can cooperate to vary the power provided to the portable power units connected to the power in bus.

[0030] The portable power unit controller can be configured to determine the primary portable power unit. The primary portable power unit can be configured to determine the power level of each of the other portable power units in the data network. If a secondary portable power unit in the data network is lower than a level determined by the primary portable power unit, the primary portable power unit can instruct the secondary portable power units to charge. The primary portable power unit can balance the charging across the secondary portable power units. [0031] Referring to Figure 2, the portable power units can provide power to various loads individually or collectively. The portable power units can be connected to a power out bus 30. The portable power units can be hot swappable on and off the power out bus. If a secondary portable power unit is removed from the bus, the primary portable power unit can be informed and power from the remaining secondary portable power units can be delivered to the power out bus. If the primary portable power unit is removed, the next inline secondary portable power unit can assume the role of the primary portable power unit.

[0032] The system can include an external power controller 32 in

communications with the portable power units. The external power controller can be configured to allow power to be delivered to a load, such as to a junction box 34, from an external power source 18, from the solar array 10, from the portable power units, individually, in combination, in series or in parallel, or any combination thereof. In the example of the junction box 34, the junction box can be included in a circuit 36. The circuit can include outlets, switches and lights. When the external power controller prevents external power from entering the junction box, circuit 36 is unpowered. When unpowered, one or more portable power units can be connected to the circuit, such as by plugging the portable power unit into an outlet as shown by direct connection 38, to provide power to the circuit resulting in an“off the grid” power supply for the one or more circuits. Therefore, this system can be configured to have solar power, external AC power, portable power supply power or any combination thereof.

[0033] Referring to Figure 3, an example of a portable power unit 40 is shown. The enclosure 42 can include an interface plate 44 with various output and input connectors which can include AC power, DC power and varying voltages and amps. A battery module 46, fan 48, transformer 50 for AC to DC, DC to AC, voltage or amperage changes, display 52 and portable power unit controller 54 that can be in electrical communications in the enclosure. The enclosure can include a handle 56 and supports 58. Status indicators 60, such as lights, can be included. A door panel can cover the interface plate.

[0034] Referring to Figure 4, a solar array 10 and external AC power source 18 can be connected to a controller 12. The controller can be connected to an AC output 62 and a DC output 64. The controller can be connected to a power bus 66 that can be connected to a storage unit such as portable power unit 21. The controller can include computer readable instructions that can determine if an AC load or a DC load 67 is connected and based upon the power requirements of the load, draw power from one or more storage units according to the load. A device lookup table can us used to determine the amount of power to draw from the storage units and deliver to the load. For example, if the controller determines that the load is drawing 1 amp and about 5 volts, the controller can use this information, access a device lookup table and determine that the device is likely a smartphone. A smartphone with a depleted battery can charge in about an hour with a 1 amp, 5-volt charge course. Therefore, the controller can deliver 1 amp and 5 volts to the load for an hour at which point saturation can be reached such as when voltage peaks and the current decreases. At that point, the controller can deliver a topping charge after a certain period of time such as after 3 hours and occasionally apply the topping current until the load is removed. If the controller determines that the load is drawing 1 amp and about 10 volts, the controller can use this information, access a device lookup table and determine that the device is likely a tablet. A laptop can be as high as 25 volts. By understanding the load charge specifications, the controller can deliver the appropriate power to the load, avoid unnecessary power delivery, extend the life of the storage units and prolong the time the system can delivery power.

[0035] The portable power units can be designed in sets. A set of base power units 68 can be used to receive charging power from the controller and delivery Charing power to other storage units such as 70. One or more units from a set of delivery units 72 can be used delivery power to a load. A set of portable power units 74 can be removably connected to the power bus 66. A unit in the set portable power units can also be included in the base power set or the delivery set. A portable power unit 76 can be connected to the power bus by direct connection, cable, contacts or induction.

Wireless power transfer (e.g. induction, wireless power transmission, wireless energy transmission, or electromagnetic power transfer) allows for the transmission of electrical energy without a physical connection. A transmitter device can be connected to the power bus to generate a time-varying electromagnetic field, which transmits power across space to a portable power unit. The portable power unit extracts power from the field and can eliminate the use of the wires.

[0036] Referring to Figure 5, a solar array 10 can be connected to a distribution bus 78, The distribution bus can include computer readable instructions for determining the input power and the amount of solar power to distribute to a base power storage system 80. The base power storage can be a pennant power storage system such as batteries that is fixed in position. The base power storage is charged from the solar array 10 or can be charged with another external source such as AC power from a grid, generator or other source. The base power storage can be connected to a power input controller 82 that can include computer readable instructions for delivering power to one or more storage units or portable power units 21 through a power bus 66. The amount of power that is delivered to a storage unit can depend upon the charge of the storage unit. Storage units with less charge can be charged first so that the charge is balanced among the storage units in the set of storage units. The storage units can be connected to an output controller 84 which can be attached to a load 67. The input controller can also provide power to one or more capacitors 86. The capacitors can be also be super capacitors, so that charging time is significantly reduced. A set of capacitors can be used that include AC capacitors, DC capacitors or a combination so that the load attached to the set of capacitors can receive AC or DC power. External AC or DC power 18 can be connected to the output controller to the distribution bus so that the base power storage, storage units, capacitors or output controller can receive power from the external power source.

[0037] Referring to Figures 6A and 6B, the power system can be placed on a mobile platform 88 such as a trailer. The trailer can support storage units or portable power units 90, base power source 92 and capacitors 94. The storage units, base power source and capacitors can be placed in water resistant or waterproof containers carried on the trailer. The weight of the components on the trailer can be positioned so that approximately 60% of the weight is loaded on a front portion of the trailer and the remaining weight should be disposed on and behind one or more axles. [0038] A solar panel support 96 can be carried by the trailer and support one or more solar panels of a solar array 10. A port panel 98 can provide power output and input ports and be disposed under a cover 100 that can pivot upwards for access.

[0039] Referring to Figure 7A and 7B, a solar array 10 can be carried by the trailer and include a set of solar panels. The solar array can have a retracted position where the solar panel array is lowered reducing the height of the system for

transportation. The solar panel array can be raised upward above the trailer allowing sufficient clearance between the solar panel array and the trailer bed for access to the components carried by the trailer including the base power source, storage units, capacitors and controllers. The solar panels of the solar panel array can be joined by hinges 102 allowing the solar panels to be deployed increasing the amount of light that can breach a solar panel. A first solar panel 104a can be support by standard allowing the first solar panel to be raised and lowered. A second solar panel 104b can be hinged to one side of the first solar panel and be retracted (Figure 7A) or deployed (Fig re7B). A third solar panel 104c can be hinged to one side of the first solar panel and be retracted (Figure 7A) or deployed (Fig re7B). When deployed the solar panel array can be raised to provide clearance under the solar panel array and increase the power available to the various components from solar power. Further, the weight distribution above and the lowered solar panel array improves the performance of the trailer when in motion.

[0040] The storage units, delivery units, base power source, capacitors, output controller can include outputs such as AC, DC, USC, batter connectors, USB-C and the like. [0041] The portable power unit controller can include a computer readable medium having computer readable instructions. Various aspects described herein are directed to different methods, systems, and computer programs and instructions relating the utility and communications of the system. The portable power units can act as nodes to a network and communicate between the nodes. A microphone, speaker and display included in the portable power unit can allow users to communicate between the various portable power units. The reserve portable power units can be kept charged and in reserve conversion to a primary or secondary portable power unit or used remotely. The portable power unit controller can include a transmitter, receiver or transceiver and send information, such as status information, to another device. For example, a portable power unit can send a low power warning to a smart phone, or other receiving device notifying that the portable power unit should be charged, replaced or otherwise attended.
