Does any know how these kind of setups work for shared GFCI circuits? Like if I have a couple bathrooms on the same circuit as an outdoor GFCI plug I’d like to use with 1200 watts of panels, is that doable?
The devil is in the details of “a couple bathrooms”. Is it just led lights and ceiling fans? No problem, especially if it’s a 20A circuit. If for some reason you plug in a space heater and a hair dryer then you have issues. So you really to figure out what is/will be running to eliminate the risk of burning your house down.
