Title:
INTELLIGENT ENERGY-SAVING DEVICE FOR ENERGY STORAGE INVERTER SYSTEM
Document Type and Number:
WIPO Patent Application WO/2019/169593
Kind Code:
A1
Abstract:
An intelligent energy-saving device for an energy storage inverter system. According to the device, a load access detection circuit is additionally arranged between a control module of an energy storage inverter system and an AC output unit of the energy storage inverter system; the load access detection circuit is used for detecting whether the AC output unit is accessed by a load, and feeds back a detection result signal to the control module; and the control module is used for conducting and disconnecting power supply of a power consumption unit. Since a load access detection circuit is additionally arranged between a control module of an energy storage inverter system and an AC output unit of the energy storage inverter system, the control module disconnects power supply of a power consumption unit when the AC output unit is not accessed by a load, and the power consumption of the system itself in an offline state is reduced, thus the energy utilization rate is maximized while the service life of a battery is prolonged.
