📱 Fox ESS Wi-Fi Reconnection Guide (Using the App)

If your Fox ESS system shows offline in the FoxCloud app, it’s usually just a Wi-Fi issue. Most often this happens after you’ve changed your broadband router or Wi-Fi password.

Follow these steps to reconnect using the FoxCloud app.


Step 1 – Open the App

  1. Open the FoxCloud app on your phone.
  2. Log in with your installer/customer account.
  3. Tap the “MyFox” icon in the bottom right corner.

Step 2 – Select Wi-Fi Settings

  1. Tap on your inverter/datalogger device.
  2. Go to Wi-Fi Settings.
  3. Choose Reconfigure Wi-Fi.

Step 3 – Put Dongle in Setup Mode

  1. On the inverter, press the reset button on the dongle for ~5 seconds until the LED flashes quickly.
    • This means the dongle is ready for setup.

      On your phone, the app will prompt you to connect to the dongle hotspot (W-xxxxxxx ).

    • Default hotspot password: mtmt2020

Step 4 – Enter Your Home Wi-Fi Details

  1. In the app, select your home Wi-Fi (2.4 GHz only).
  2. Enter your Wi-Fi password carefully.
  3. Tap Confirm / Save.
  4. The dongle will reboot and reconnect to your Wi-Fi.

Step 5 – Confirm Connection

  • Within 5 minutes, your inverter should show Online in the FoxCloud app.

    LED indicator:

    • Slow red flash with green blinks = Connected
    • ⚠️ Rapid red flash only = Not connected (retry setup)

Troubleshooting

  • Wi-Fi not found? Ensure your router is broadcasting 2.4 GHz. Fox ESS does not support 5 GHz.
  • Wrong password? Re-run the app setup and carefully re-enter.
  • Still offline? Try resetting the dongle (hold reset for 10 seconds) and repeat the steps.
  • Weak signal? Place a Wi-Fi extender closer to the inverter.
