Enphase Energy System warranties

Understanding the warranty coverage of your Enphase system is an essential part of solar ownership. Whether you're checking how long your microinverters are covered, confirming your battery's warranty period, or simply getting familiar with the system details, the Enphase App makes it easy to view all of this in one place. The information is personalized to your setup and gives you clarity on which devices are covered, for how long, and when the warranty terms began. 

This can be especially helpful if you're considering a system upgrade, planning to sell a home, or just want peace of mind knowing what support is available if something goes wrong. All the key device-level details—like serial numbers, coverage timelines, and more— can be checked through the app. 

If you purchase a home with an existing Enphase Energy System, the seller or real estate agent will hopefully provide you with the installer’s information. If not, you can track down the installer through serial numbers on the Enphase devices in your system. Just contact Enphase Support with the serial numbers, and we should be able to help match them to the system and installer.

If that installer has gone out of business, you’re still covered by Enphase warranties for any Enphase components. Plus, you can add Enphase Care to ensure even wider protection for you and your system.

As we mentioned in the first section of this tool, adding an Enphase Energy System to your home can increase its value. So if you decide to sell your home, then you and your realtor should discuss how the system adds to the sale price, and make sure they highlight this benefit for prospective buyers.

Transferring ownership: When you transfer ownership of your home to a buyer, ownership of your system transfers too. If you paid cash upfront for your system, then transferring ownership is simple.

But if you're paying for the system over time with a loan that still has an outstanding balance, or you had it installed with a lease arrangement, then you’ll need to check with your lender or solar installer to make sure the loan or lease can transfer to the new owner. The same goes with a power purchase agreement.

Documentation: Hopefully you’ve kept all the information about the system, as well as copies of approved permits and other documentation. You should provide the new homeowner with all the relevant information you have, including system warranties, performance guarantees, and details about any existing tax and utility incentives for which they may still qualify.
