Warranty comparison
SolarEdge vs SMA
The same four questions asked of both: how long on parts, how long on labour, what has to be registered, and what has to stay true.
Checked 16 August 2026
On warranty terms
SolarEdge
Asks less of you across labour, conditions and term length.
On warranty terms alone, SolarEdge asks less of you. Neither pays toward labour on the lines in this catalogue, so the truck roll is yours either way.

SolarEdge's standard 12 year inverter term needs no registration and starts at the earlier of installation or four months from shipment. The only clock is the paid extension: if the customer wants 20 or 25 years, it has to be bought within 24 months of shipment. The commissioning app handles registration itself.

SMA
Checked 16 August 2026
SMA's US residential inverters carry a 10 year factory warranty. Registering in SMA's Online Service Center is how the warranty record attaches to the unit, and it is the door to paid extensions later, which can be bought any time during the factory term up to 20 years total. No dated deadline was found.
