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 important to note that Europe has 220/240v by default so most household wiring is robust to higher wattages at lower amps.
The top amperage is typically about the same as in the US, actually, at least where I am: 15-16 amps. So we get 3000 watt kettles instead of 1500, and such.
