This invention is a three-in-one V2G home energy system using the bidirectional AC / DC module inside an EV charging station. It links an EV battery, home storage battery, solar system, grid and household loads without a separate storage inverter. The charger converts vehicle DC power to AC for grid export or home supply, enabling V2G, V2H and V2X. It can also charge or discharge home storage, transfer stored energy to an EV, support simultaneous AC and DC charging of two vehicles, optimise solar-only charging and manage household energy priority.
