Questions shoppers ask
Which brand of home batteries & power has the best warranty?
On paper, Tesla Energy scores highest, with 10 years of full coverage and longer coverage on some parts. Enphase covers everything longest, at 15 years.
Is a long warranty on home batteries & power really that long?
Often not for the whole product. Many longer warranties cover only certain parts after the first year or two, and you usually pay for the labor. The bars above show full and partial coverage separately.
Do I need to register to get the warranty?
6 of 16 brands require registration for some of their coverage, often within a set number of days. Keep your receipt either way.
