Working Principle Video of 12kW/32kWh PV Energy Storage System

This 12kW/32kWh PV energy storage system adopts 18 pieces of 650W panels divided into two series strings for convergence. DC power flows into the hybrid inverter. Solar power supplies loads first on sunny days, with surplus energy stored in two parallel 16kWh lithium batteries. Batteries discharge for power supply under weak sunlight, supporting off-grid operation or grid connection.
