Abstract
A method of retrofitting an electrical panel includes removing an interior from a panel housing of the electrical panel. The method includes installing a microgrid interconnect device (MID) into the panel housing into a position formerly occupied by the interior, connecting first and second lines and a neutral line of the panel housing to the MID, and installing the interior onto MID, with the MID between the interior and a back interior surface of the panel housing. The method includes connecting respective busses of the interior to the MID.

A method of retrofitting an electrical panel comprising:
- removing an interior from a panel housing of the electrical panel;
- installing a microgrid interconnect device (MID) into the panel housing into a position formerly occupied by the interior;
- connecting first and second lines and a neutral line of the panel housing to the MID;
- installing the interior onto MID, with the MID between the interior and a back interior surface of the panel housing;
- and
- connecting respective busses of the interior to the MID.
A microgrid interconnect device (MID) comprising:
- a switching device;
- a first line connector electrically connected to the switching device and configured to connect to a first line of an electrical panel;
- a second line connector electrically connected to the switching device and configured to connect to a second line of the electrical panel;
- a first load connector electrically connected to the switching device;
- and
- a second load connector electrically connected to the switching device;
- wherein the switching device is configured to switch back and forth between an ON state and an OFF state,
- wherein in the ON state, the switching device electrically connects the first line connector to the first load connector and electrically connects the second line connector to the second load connector, and
- wherein in the OFF state, the switching device electrically isolates the first line connector from the first load connector and electrically isolates the second line connector from the second load connector.
An electrical panel comprising:
- a panel housing defining a back interior surface and including a first line and a second line;
- an interior in the panel housing;
- and
- a microgrid interconnect device (MID) in the panel housing between the interior and the back interior surface, wherein the MID is connected in electrical series between the interior and the first and second lines in of the panel housing.
