Working Principle Video of 22kW/45kWh PV Energy Storage System

This 22kW photovoltaic energy storage system adopts two sets of 11kW hybrid inverters. Twenty-eight 585W solar panels generate DC power and connect to inverters directly. On sunny days, solar power supplies household loads preferentially, and surplus electricity charges three 15kWh battery packs. When sunlight is insufficient, batteries discharge and convert DC into AC power to supply loads. The system realizes self-consumption of solar energy and can operate stably off-grid.
