1. A system comprising:
a charger including a charging circuit and a discharge circuit coupled to a charging connector for an electric vehicle (EV), and the charging connector is bi-directional;
the charging circuit supplies an ingoing power from a main electric panel of a structure to the charging connector;
the discharge circuit receives an outgoing power through the charging connector and splits the outgoing power in voltage levels using a transformer; and
a manual transfer switch directly integrated within the discharge circuit that feeds backup power using the voltage levels to a sub-panel for electrical circuits of the structure during a power interruption, and the sub-panel is external from the charger and the manual transfer switch and the discharge circuit are located within the charger.
