Reconnecting your Fox ESS inverter to new Wi-Fi

Your Fox ESS inverter talks to the internet through a small Wi-Fi dongle plugged into it. If you get a new router, change broadband provider or change your Wi-Fi password, the dongle loses its connection and the app stops updating. Your solar and battery keep working as normal. Only the monitoring stops.

Before you start

• Your Wi-Fi must be 2.4 GHz. Fox ESS says setup may fail on a 5 GHz network. Many routers broadcast both, often with similar names. If you're not sure, check your router's settings or ask your broadband provider.
• Have your Wi-Fi name and password ready.
• Stand close to the inverter with your phone.
• Make sure you're logged into the FoxCloud app with your own account.

Reconnecting in the FoxCloud app

1. Open the app and tap Me.
2. Tap WLAN Configuration. The app will look for nearby devices.
3. Pick your inverter's dongle from the list and tap Connect Network.
4. Choose your home Wi-Fi, type the password carefully and tap Next.
5. Wait while it connects, then tap Finish.

It can take a little while for fresh data to appear in the app, so give it some time before checking again.

If it doesn't work

• Double-check the password. It's case-sensitive.
• Make sure you chose the 2.4 GHz network, not the 5 GHz one.
• If your router is far from the inverter, the signal may be too weak. A Wi-Fi extender near the inverter can help.
