PV off-grid system:
PV off-grid system is stand-alone system that is not connected to grid or other generator. Off-grid system powers the loads independently, widely applied to regions without power, field working, communication station.
Parts in PV off-grid system:
PV off-grid system mainly consists of solar module, battery, solar charge controller, and cable. DC-AC inverter will be added for if in AC off-grid system.
Principle of PV off-grid system:
At daytime, solar module converts solar energy into electricity, which will be stored into battery and power the load. At night, the electricity in battery will power the load.
