Stand-alone Operation Check

Confirm that the DC Switch-Disconnector on the outside of the inverter, the grid-tied breaker in the home breaker box, the
breakers in the back-up breaker box, and the switch inside the storage battery unit are the OFF position. Activate power as
explained in the following procedure.
Supplying power to improperly connected wires will damage the inverter or storage battery unit.
