Fronius Solar.SOS answering your technical queries

Fronius Online Support with Solar.SOS

Fronius Solar.SOS is our solution for all technical queries from installers. The service process can be initiated online using an app or the desktop version at the installation location itself – just by using the serial number of the inverter or a state code.

In the space of a few clicks, Solar.SOS supports you with troubleshooting and ordering replacement parts. The big advantage is that with Solar.SOS you can resolve technical problems yourself as and when they arise.

  • Manage multiple accounts, all from a single account
  • All orders at a glance (case overview)
  • Rapid ordering of replacement parts
  • Check the status of orders with ease
  • Messaging function with technical support (case messages)
  • Push notifications, e.g. information on current order status
  • Access to all relevant Installation Instructions and Operating Instructions (YouTube, etc.)

Benefits of Fronius Solar.SOS


We make on-site troubleshooting easier and provide a straightforward state code request. The request is submitted directly, so there is no longer any need to call Technical Support.


Rapid ordering

No more waiting on the phone - orders for the repair or replacement of inverters or their components can be handled more quickly and efficiently giving you greater flexibility. This function can be used in the app and in the desktop version.


Get access to all relevant Installation Instructions and Operating Instructions. All video tutorials are also available to you.


One login & account - endless options

The central Fronius login page gives you access to our online tools like Fronius Solar.start (start-up app for inverters) and Fronius Solar.web (system monitoring). You also benefit from a single account in which you can manage multiple other accounts, making it easy to integrate systems from different companies, for example – and so consign tedious logging in and logging out to the past.

Solar.SOS provides a clear overview of all service callouts so that relevant information is available to you at a glance. User-defined settings can be specified for customised views. We will also keep you informed of important updates in the Notification Center.
