I have something like that I bought here in the US but the power generated won’t power the whole home. It does charge my emergency battery though for when the power is out.
Right but the way I understand it is if you get the plug in style and let it generate some power during the day it will offset your usage and save you money on the bill.
Yes, lile that. There are also types (like the Anker generators for mobile homes / boats etc) which can run stand-alone, but the German balkony solar panels just add cheap supply to the domestic power use by plugging it into the household AC system.
No reason it can’t be done on 120v (from a technical level). In fact, most solar inverters in the US could do this at a technical level as they basically do the same thing, just on a larger scale (higher current and therefore are wired in to electrical panels rather than through outlet as outlets have lower current limits). All you need is the inverter to synchronize its AC output to match grid. If you had a smaller inverter, you could just connect it to an outlet (ignoring building codes, insurance, and other non technical reasons). So the choice is then to have centralized larger inverters or smaller inverters per panel or 2. If you live in a very densely populated area where you can only pit a panel or 2 on a balcony or you don’t have control of your electrical panel, then the small inverter method makes sense.

I think you guys running 220 through the whole house is why we don’t have that stateside, just a guess.

to power the whole home you need a hell of a lot more than the balcony ones. but every little bit helps.
