36 more countries: what applies to a inverter there
No model rows for these countries — they publish no usable list, or GridFit has not parsed it yet. The state 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.
