1. Working principle:
Off-grid Solar power systemis that solar panel charges the solar energy after sunshine to transfer into the electric power and store in the battery, through the controller’s over-charging and discharging protection and invert transformation, supply to electric appliance.

This system configuration is for reference, it can be adjusted based on actual condition and requirement.
4. Features of solar power system:
1. Off grid solar power system is mainly used for application with relatively-small power consumption, and the areas have no grid network coverage, or grid power is unstable or outage condition.
2. It’s composed of solar panels, controller, inverter, battery bank, solar panel mounting racks, and other accessories required for a complete home solar power system.
3. The battery bank gives a stable power output to the solar inverter which converts DC to AC to power loads, and provides power backup in rainy or cloudy days.
4. The solar panels generate electricity at daytime and charge the battery bank .
5. The off grid home solar power system provides grid power bypass in case of battery power shortage when sunshine is not enough.
6. All the off grid home solar power system configurations are worked out by scientific calculation and design.
