Newest configuration CE RoHS 3KW independent solar system energy
1.Off-Grid solar system is composed of solar panels, controller, inverter, battery bank, solar panel mounting racks, and other accessories required for a complete system. 2.The solar panels generate electricity at daytime and charge the battery bank through the controller. 3.The battery bank gives a stable power output to the inverter which converts DC to AC to power loads, and provides power backup in rainy or cloudy days.
4.The controller gives an intelligent control of whole system process and provides various protections.

About working principle:
This is an off-grid system which uses batteries to store the solar energy, at the same time, the system can be connected with the grid for utilization of grid power. The system uses battery power in priority, but when sunshine is not so good or loads consumption is too big which caused the battery power inadequacy, then the system can switch automatically to grid power supply. Meanwhile, the system can charge the batteries with grid power until batteries are fully charged. Then the system will switch back to battery power supply.
