Warranty comparison

Enphase 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

Enphase

Asks less of you across labour, conditions and term length.

On warranty terms alone, Enphase asks less of you. Neither pays toward labour on the lines in this catalogue, so the truck roll is yours either way.

What separates them

  • Neither pays toward labour on the lines in this catalogue, so the truck roll is yours either way.
  • Enphase has the longer parts term at 25 years, against 10 years.

Enphase

Checked 16 August 2026

Enphase IQ8 microinverters carry 25 years, applied from Enlighten activation, so the thing to confirm is that activation happened. In the United States Enphase also pays labour: $200 per truck roll plus $25 per replaced microinverter, and a paid Labor Protection Program extension stretches labour cover to five or ten years from activation.

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.

Warranty terms change and differ by country. This is a reading of the manufacturer's published document on the date shown, not legal advice, and not a substitute for the document that applies to the model you installed.
