Working Principle Video of 3kW 2.5kWh Off-Grid Solar Energy Storage System

This is a 3kW 2.5kWh off-grid solar energy storage system. Four 650W PV modules harvest solar energy, and the generated DC power flows into the 3kW hybrid inverter. A matched 2.5kWh lithium battery stores surplus electricity. During daytime, solar power can directly supply loads or charge the battery. At night, the battery supplies power through inversion. Modularly installed, the whole system adapts to highland environments with dust and large temperature differences, meeting basic household power demands for lighting, TVs, fans and more.
