Supported Versions - nathanmarlor/foxess_modbus GitHub Wiki

FoxESS occasionally updates the inverter firmware in incompatible ways.

We support a number of different manager versions for different models, but not all. If we don't support your manager version, you can ask FoxESS to update your inverter.

By default, this integration will try and talk to your inverter as if it was running the latest manager version. If you're running an older manager version, you can select an older version in the settings: go to Settings -> Devices & Services -> FoxESS - Modbus -> Configure -> Version settings.

Inverter	Supported by default	Selectable in settings
