Does Sungrow SG string inverters work locally with Home Assistant?

Yes, according to the public sources: the HACS integration “Sungrow Local” talks to it over the local network, read-only as far as we can tell; evcc supports it locally and lets evcc control it.

Firmware updates can open or close local access — check the integration's own page before you buy, and your installer before software changes export limits or charges a battery from the grid.

The other 36 countries: a inverter there

No model rows for these: they publish no usable list, or GridFit has not read it. Each gets one answer by the same rule as the grid view — the maker's own document first, then the country's type-A ceiling, then what the lists read say.

Fit by the maker's document (12)

Sungrow's own document names these countries — the grid operator still decides at the application.

On 7 EU lists (AT, BE, CZ, EE, NL, PL, SE): the maker has had the model certified and 7 grid operators accept it. Nothing is checked in these countries themselves: where there is no list the grid operator reads the maker's certificate for that country — ask the maker or installer for it; where a list exists that GridFit has not read, check the model there.
