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.
✓ Fit: nothing to approve for this kind of device (3)
On 2 EU lists (BE, NL): 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.
This kind of device is not allowed to be connected.
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.
