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
It’s also worth noting that some of the issues get a lot easier at 230VAC
We are effectively on twice the voltage. Since P=I^2 R the effective heating is quadrupled. This makes American wiring a lot more vulnerable to overloading than Europe or China.
