A Brief Outline of Our Warranty Models



Fronius Warranty

The Fronius Warranty offers warranty protection for the material over the entire service life.
 


Fronius Warranty Plus

The Fronius Warranty Plus covers the material, servicing, and transport costs.
 

Essential: The latest software version

The inverter software must be regularly updated in order to ensure smooth operation of the photovoltaic system.

Ongoing inverter software updates not only guarantee a low failure rate and better serviceability of the device, they also ensure optimal system performance.

Two Options for Regularly Updating Inverter Software

  • Bringing the PV system online in Fronius Solar.web**: With this option, an inverter update can be started online. Fronius reserves the right to carry out updates automatically.
  • Manual checking and, if necessary, update of the inverter software every 3 months

Purchase warranty extensions for even greater protection

Reliability, a long service life and sustainability play a crucial role for PV system owners, just like they do for Fronius.

This is why we are offering you the option to extend the warranty for up to 20 years. System owners thereby benefit from the uniquely high-quality service of our Fronius Support team reliably and in the long term.  

Fronius warranty extension 

The Fronius Warranty Extension is a cost-effective way to protect system owners against risks. If a claim is made, Fronius will provide the relevant materials, and the warranty holder does not have to pay for the spare part.

Fronius warranty extension plus 

The Fronius Warranty Extension Plus provides you with comprehensive cover. If a claim is made, in addition to the material costs, Fronius also covers labor costs for removing and installing the spare part, as well as any transportation costs.  

 

* Warranty conditions and services may vary depending on the country and region. Fronius accessories are excluded from product registration. The prerequisite for free warranty extension is registration of a new Fronius inverter, which was commissioned after 09/01/2023, in Fronius Solar.web. For further requirements or limitations of the warranty, please refer to the warranty conditions for your country.

 ** The prerequisite for this is the maintenance and provision of an Internet connection.
