Enphase warranty for home batteries & power

60/100 Warranty ScoreRanked 3 of 16 brands
The short version

Enphase covers home batteries & power in full for 15 years, with no partial coverage after that. That full coverage is longer than most of the 16 brands we compared, which typically cover nothing in full. Some of this coverage only applies if you register the product.

From Enphase's published warranty, checked October 2026.
