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 (24)

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

On 3 EU lists (BE, PL, SE): the maker has had the model certified and 3 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.

Other procedure: over the type-A limit (1)

Italy

Above the type-A ceiling (11.08 kW in Italy): type B, a procedure of its own — conformity per installation, not a certificate per model.

Unknown: not confirmed (11)

Albania?Bulgaria?Georgia?Iceland?Latvia?Montenegro?North Macedonia?Malta?Serbia?Ukraine?Kosovo?

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.
