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.

Possibly fit: accepted on other EU lists (32)

AlbaniaBosnia and HerzegovinaSwitzerlandCyprusGermanysDenmarkFinlandFrancesGreat BritainGreecesCroatiasHungaryIrelandIcelandLiechtensteinLithuaniaLuxembourgLatviaMoldovaMontenegroNorth MacedoniaMaltasNorthern IrelandNorwayPortugalRomaniaSerbiaSloveniaSlovakiaTürkiyeUkrainesKosovo?

On 2 EU lists (PL, SE): the maker has had the model certified and 2 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 (2)

SpainItaly

Above the type-A ceiling (100 kW in Spain, 11.08 kW in Italy): type B, a procedure of its own — conformity per installation, not a certificate per model.

Unknown: not confirmed (2)

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.

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