Is my inverter fit for the grid operator's list in Slovakia?Is my wallbox fit for the grid in Slovakia?
Does my inverter work locally with Home Assistant and evcc? — the two marks at the right of each row
Loading the table…
✓ fit: on the list✓ fit by the maker's document — the grid operator decides✕ not fit: refused, expired or not allowed nothing known — never “not approved”Hover or focus a cell for the list's own word, a condition or date, firmware and the row.
Column head: list = the country has a public list · cert. = no list, the grid operator checks the maker's certificate · — = nothing to check for this class.Local = the best route on your network: control / read / cloud / brand route.Smart home = who talks to it, Home Assistant then evcc, each mark coloured by its own route: local control · local, read only · cloud only · brand route, model unconfirmed · empty = not found. Marks are GridFit's own glyphs, not the projects' logos.
Phases and rated power (kVA) come from the Austrian, Swedish and Belgian lists. No list carries MPPT counts: those are the makers' own datasheets, read so far for Deye, Fronius, GoodWe, Kostal, SMA (model codes exactly as the sheet writes them); “–” means not collected, never “none”. The list is the authority; this is a cross-reference.
Slovakia: partial list
A list exists but is partial: frozen, members-only, a certificate register rather than an approval list, or not reachable.
