Fox ESS

Connecting your Fox ESS system to our app

To automatically transmit your meter data from Fox ESS to us and to make the most of our intelligent features, a direct connection between your system and our app is required.

This guide shows you how to set up this connection yourself in just a few steps.


To connect your system to us, you only need the credentials for your Fox ESS cloud account.
Enter these when adding your system and then select your specific system.
Finally, grant us permission to retrieve your system data and control the system.
Please note that you must use an end-user account.


Important note on AI-based battery storage control

Would you like to use our intelligent, AI-based battery storage control to further optimize your self-consumption?

Please ensure that your Fox ESS system is running at least software version 2.0 (or a newer version).

  • How to check the version: You can generally find the current software version in the system information of your Fox ESS inverter or in the online portal.
  • Update required? If an older version is installed, please contact your installer or Fox ESS support directly to perform the free update.
