FAQ

Does inverter long warranty mean high quality?

The European Sunny Boys are only warrantied for 5 years. iPhones only have a one year warranty. Does that mean Apple products aren't reliable? Enphase offers a 25 year warranty on their inverters but only one year on their monitoring. Does this mean their monitoring is not as reliable as their inverter? Of course not. 

Offering long warranties have very real costs. If we were to offer a 25 year warranty, we would have to hold a higher reserve on our balance sheet, making our products more expensive. We think that our customers would rather have our high quality products at a lower cost.
