The other 36 countries: a plug-in solar 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.

Accepted on other EU lists (12)

Switzerland Germany^s Spain France^s Great Britain Greece^s Hungary^s Italy^s Liechtenstein Lithuania^s Montenegro Romania

On 2 EU lists (AT, BE): 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.
