Video: Working Principle of 3.5kW/5kWh Hybrid PV Energy Storage System

This 3.5kW/5kWh hybrid PV energy storage system uses four 590W solar modules to capture sunlight and generate DC power. The hybrid inverter converts DC into AC to power household loads such as refrigerators and washing machines. Excess solar energy charges the 5kWh battery. When sunlight is insufficient, the battery discharges to supply loads. The system can automatically switch among PV, battery and utility grid, delivering stable power and reducing grid electricity consumption.
