Submit SuggestionEuropean solar inverter manufacturers on this page are SMA Solar and KOSTAL Solar Electric from Germany, Fronius from Austria, Victron Energy from the Netherlands and Ingeteam from Spain. The inverter converts the direct current of the solar panels into alternating current for the home and the grid, and many models also manage a battery. A brand counts as European here when the company behind it has its headquarters in Europe.

What Europe does not offer here
None of the brands listed here is a microinverter specialist, so module-level conversion is not covered on this page. Chinese manufacturers are also major inverter suppliers and are not listed here. Inverters are normally installed by qualified installers who also take care of the registration with the grid operator. Check the warranty terms and the monitoring app, including where the data is stored.
Frequently asked questions
Are there European alternatives to Enphase?
Yes, for string and hybrid systems. See European alternatives to Enphase, and note that Enphase uses microinverters on each panel, which works differently.
