The integrated smart solar + storage + charging system developed  consists of solar power generation, energy storage, EV charging, energy management and other units to achieve power generation, charging/discharging and energy storage. Solar power generation supplys power for loads and EV charging. The excess power feeds back into the grid with tariff paid, achieving additional profit. The energy storage system can be used to store excess energy of solar power to be discharged at user’s will. The battery also doubles as an emergency backup when the grid is unstable or during power outages.
