III. System Working Principle

1. During daylight, solar panels convert sunlight into direct current (DC) electricity.
2. DC electricity passes through the inverter, converted into alternating current (AC) to directly power household appliances.
3. Excess AC electricity is converted back to DC by the inverter for storage in the battery.
4. At night or on cloudy days, DC electricity from the battery is converted into AC by the inverter to power household appliances.

In case of power outages, the inverter automatically switches to emergency power supply mode, powering household appliances.
