Fronius offers extended warranties of up to 20 years for the Fronius IG, Fronius IG Plus and Fronius IG central inverter series.

Fronius inverters with nominal outputs of 1.3 to 40 kilowatts come standard with a five-year manufacturer's warranty.
This can now be extended to 10, 15 or 20 years for the string inverter series Fronius IG and Fronius IG Plus.
The warranty period for Fronius IG central inverters can also be extended to 10 or 20 years.
 
The extended warranty guarantees that system operators can have devices repaired or replaced even after the standard warranty period has expired.

Applying for an extended warranty for Fronius inverters: 

The extended warranty can be ordered simply via an item number like an inverter or any other Fronius system component.
This can be done right when you order the inverter or up to six months after the system is installed.
A corresponding certificate will be provided as proof of the extended warranty.
