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^?Switzerland Cyprus Germany^s Denmark^?Spain Finland France^s Great Britain Greece^s Croatia^s Hungary Ireland Italy Liechtenstein^?Lithuania Luxembourg Moldova^?Northern Ireland^?Norway Portugal Romania^?Slovenia^s Slovakia Türkiye^?

On 2 EU lists (CZ, EE): 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.

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.

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.

Local control with Home Assistant and evcc

Checked 2026-10-31.

not found Not found in Home Assistant core, the HACS default list or the evcc templates under this brand (checked 2026-10-31). That is not “does not work” — it means no source we read names it. Know a route?
