Warranty Process & Information

At Fronius, we have been making power electronics equipment for over 70 years. At our ISO 9001 certified production plants, we make only high quality products that we proudly stand behind.
Fronius inverters are built to last and withstand most wear and tear, but they are not indestructible power electronics. In the event that your inverter needs to be serviced, we have our warranty procedures and services for you.

Fronius Warranty Extensions
For security beyond the duration of the standard Fronius Warranty, you have the choice to extend the warranty duration fee-based up to 10, 15 or 20 years. For your maximum flexibility, we offer different warranty extensions. See this document for more information.
Our service process
In the event that your inverter needs to be serviced, you must follow our policy and procedure for warranty returns and repairs. Please see the document Declaration of Consent on the right.
