The inverter converts DC power from your panels to AC for your home. Choosing the right type — string, microinverter, or hybrid — matters as much as the panels themselves. European installers increasingly recommend hybrid inverters as battery prices fall.

For string inverters in Europe, SMA Sunny Boy and Fronius Primo have the deepest track records and best local service networks. Enphase IQ8+ leads microinverters. For hybrid inverters (the right choice if you plan to add battery storage), SolarEdge, Fronius GEN24, and GoodWe dominate the residential market.
A string inverter only converts DC from panels to AC for the grid. A hybrid inverter does that too, plus it manages charging and discharging a battery bank. If you plan to add a battery within 5 years, a hybrid inverter is cheaper and more efficient than retrofitting storage to a string setup.
Not necessarily — you can add an AC-coupled battery (Tesla Powerwall, Enphase IQ Battery) to any grid-tied system. But hybrid (DC-coupled) is more efficient, simpler to install, and usually cheaper than retrofit.
String inverters typically last 10–15 years (warranty 5–12 years). Enphase microinverters carry 25-year warranties and usually outlast the panels. Hybrid inverters fall in between at roughly 10–15 years. Budget for one inverter replacement over a 25-year solar system life.
In most EU countries, grid-tied inverters must be installed by a certified electrician to comply with network-connection rules (e.g. VDE-AR-N 4105 in Germany, CEI 0-21 in Italy). Off-grid inverters may be installed DIY in some jurisdictions, but warranty is usually conditional on professional installation.
