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)

Bosnia and Herzegovina?SwitzerlandCyprusGermanysDenmark?SpainFinlandFrancesGreat BritainGreecesCroatiasHungaryIrelandItalysLiechtenstein?LithuaniaLuxembourgMoldova?Northern Ireland?NorwayPortugalRomania?SloveniasSlovakiaTürkiye?

On 6 EU lists (AT, BE, CZ, EE, PL, 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.
