A firmware update of the Wattpilot can only be carried out via the Solar.wattpilot app for Android and iOS.

The package 'Fronius Solar.update/Agilo' contains the latest software for Fronius Agilo inverters. It can be executed via Fronius Solar.Service software.

We recommend reloading the country setup of the inverter (e.g. Setup DE, Setup ES, etc.) after a firmware update to apply all changes to the memory. Please consider that reloading the country setup sets all grid parameters to their default values. If any individual parameters, that differ from the national norm, are required, you have to make these changes again manually via the inverter display.
