Connecting Photovoltaic Power into Building
Connecting Photovoltaic Power into Building
(OP)
We are testing some solar panels and are trying to backfeed about 600 watts of power into our system through an existing GFCI receptacle. The GFCI keeps tripping. Grounding is installed per manufacturer, but inverter is 240 volts AC output and is passed thru 240/120VAC transformer before connecting to receptacle. I wonder if that could be an issue.

The breaker would have to be only a 3 to 6A size, unlikely an available item. Fuses a better option. The risks involved are yours and not inconsiderable. It cannot be seen as any kind of permanent installation until redone according to the NEC which may require a GFCI on the circuit.
