Working Principle Video of 40kW 75kWh PV Energy Storage System

This 40kW photovoltaic energy storage system uses 64 pieces of 650W panels to collect DC power and feed it into a 40kW three-phase hybrid inverter. Solar power supplies the flour mill loads first, and surplus energy is stored in five 15kWh battery packs. It connects to the grid normally, and switches to battery off-grid power instantly during blackouts to keep factory production running steadily all day.
