The other 36 countries: a hybrid 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.

Possibly fit: accepted on other EU lists (25)

On 6 EU lists (AT, BE, CZ, EE, NL, SE): the maker has had the model certified and 6 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.

Unknown: not confirmed (11)

Whether a list or a rule applies is not confirmed yet.

s = from search results, ? = unverified; without a mark the country page was opened. The state per country comes from the EU+ grid-connection table; each country page says more.

Rows are matched by maker and a normalised model code; the “as written” line shows exactly what each list says. Check the list itself, and your grid operator, before you install.

brand route, model unconfirmed No integration or template names this code. Solinteg has 3 families with a local route; whether this model belongs to one of them is not confirmed:

Know which family it belongs to? Fix the row: the family's model-code pattern then claims it.
