A meter socket adapter (MSA) for connecting a battery energy storage system (BESS) to a household microgrid through a meter combo load center. The MSA includes: a housing matching an electricity meter and a meter socket in the meter combo load center; a plurality of power conductors that connect among the electricity meter, the meter socket, and BESS; a meter interconnection device (MID) switch for connecting a utility grid or one or more distribution energy resource (DER) devices to supply power to household loads in the household microgrid; a MID driving circuit for driving the MID switch to close or open; and a MID connection detection circuit to verify an electrical connection of a closed MID switch.

A photovoltaic (PV) shutdown system for a PV power generation system includes a mid-circuit interrupter (MCI) controller and at least one MCI with two terminals. The two terminals of the at least one MCI are arranged for connection with the MCI controller, a maximum power point tracking (MPPT) system, and a PV string. The PV string includes PV modules connected in series. The MCI controller is arranged to turn on the at least one MCI by providing supply power and turn off the at least one MCI by terminating the supply power.
