A: The battery is charged with electricity at a lower cost to prepare for peak demand times. The charging power is intelligently adjusted according to the time-of-use electricity price.
B: During the daytime peak demand period, the load is supplied by the battery instead of the grid.
C: When there is sufficient sunshine during the day, photovoltaic power generation is prioritized to supply the load, and the excess is charged to the battery, and the remaining power is finally connected to the grid.
D: During the evening peak period, the battery is prioritized to discharge to the load, reducing the amount of electricity purchased by the grid.
