Off-grid solar power generation system uses solar panels to convert solar energy into electric energy under light, and to power the load through the solar charge controller, and to recharge the battery; in overcast weather or no light, through the solar charge and discharge controller by the storage battery to the DC load power supply, At the same time, the battery also directly to the independent inverter power supply, through the independent inverter inversion into alternating current, to power the AC load.

Off-grid solar power generation system is widely used in remote mountainous area, no electricity zone, island, communication base station and other application sites. The system is composed of PV array, Solar charge controller, battery group, Off-grid inverter, DC load and AC load.
