I’m a little wary of plug-in solar in the US. Some of the bills propose allowing 1200 watt panels which can overload wiring depending on what else is on the circuit and how in the wall wiring is run. Limiting plug-in panel wattage to, say, 400 watts might be necessary
In Germany, it’s limited to more like 800 watts (and I think some other safety regulations). As I understand it, it’s generally worked without this being much of an issue despite millions of plug in solar installs (primarily for balcony solar)
