During peak power consumption, the energy storage system can convert the stored DC power into AC power through the inverter and release it to the power grid, thus reducing the power pressure during the peak period; during low power consumption, the excess power from the grid can be converted by the inverter and then stored in the batteries for use in future peaks.
