Self-sufficient power system
During the day, power grid or the photovoltaic power generation first supplies the load, and then charges the battery; at night, the battery discharges to supply the load, and when the battery is insufficient, the diesel generator can also supply power to the load, and can be combined with diesel generators to supply loads or charge batteries.The system can meet the daily electricity demand in areas without a power grid or with a unstable power grid.
