Step 1: Reboot your Fronius system. After rebooting, check the Fronius Solar.web app to confirm that the Wi-Fi has successfully connected.

If the Wi-Fi is not connected, proceed to the Solar.start app to reconnect your Wi-Fi.

Important:

  • Make sure your modem is set to 2.4G (not 5G), as the Fronius inverter only connects to 2.4G.
  • Ensure you have a strong enough Wi-Fi signal to reach your inverter. If the signal is weak, using a Wi-Fi extender will help resolve the issue.
