My Monitoring Is Offline
Here is a support article outlining the steps to get your solar inverter back online after a Wi-Fi disconnection.
Solar Inverter Wi-Fi Reconnection Guide
When your home Wi-Fi network changes or your router is replaced, your solar inverter can lose its internet connection, which stops your energy generation from updating in the monitoring app.
Follow the step-by-step instructions below for your specific hardware.
Fox ESS
Prerequisite: Ensure your home router is broadcasting a 2.4 GHz network, as Fox ESS dataloggers require this to connect.
-
Open the FoxESSCloud (or FoxCloud) app on your smartphone and tap "Me" in the bottom right corner.
-
Select "WLAN Configuration" or "Connect to Wi-Fi".
-
The app will search for nearby Fox hardware. If your inverter does not appear automatically, tap the option to scan the QR code, which is located on your inverter's Wi-Fi dongle.
-
You now need to connect to the dongle's local network. From your phone's Wi-Fi settings, look for an available network SSID that starts with "W" and ends with the last 7 digits of your Wi-Fi dongle's serial number.
-
Return to the Fox app. In the available networks list, select your home broadband router's network name (SSID).
-
Carefully enter your home Wi-Fi password and submit. You will receive a confirmation screen once the inverter successfully pairs with the network.
This video visually guides you through the Fox ESS app settings and the exact steps to pair your data logger with a new Wi-Fi network.
Duracell Energy
Reconnecting a Duracell Energy (Dura-i) system requires connecting directly to the inverter via Bluetooth.
Note for multi-inverter setups: If your inverters are running in parallel, you must turn off parallel mode via the toggle switch in the app before starting, and turn it back on once all units are successfully reconnected to the internet.
-
Connect your smartphone to your home's 2.4 GHz Wi-Fi network and ensure you are standing within 2 meters of the inverter with your phone's Bluetooth enabled.
-
Open the Dura-i app and tap the "Local Access" button on the login screen.
-
Select your inverter from the drop-down list (the serial number will begin with a "BLE" prefix).
-
When prompted, select "End User". (If asked for a Bluetooth password that you don't know, quickly tap the Bluetooth symbol 3 times to reset it).
-
Once connected to the inverter dashboard, tap "Settings" at the bottom right.
-
Scroll down to "WLAN" and enter your home Wi-Fi SSID and password.
-
Press "Ok". You will see a countdown—wait until you see two green ticks, which confirms the system is successfully connected to your Wi-Fi.
Tesla
Depending on how your system was installed, you will reconnect your system via your Powerwall, Tesla Solar Inverter, or Gateway.
-
Stand close to your Tesla Gateway or Powerwall and ensure your phone's Wi-Fi is turned on.
-
Open the Tesla app, locate your home energy site, and select "Settings".
-
Scroll to the bottom of the screen and tap "Configure Wi-Fi".
-
Follow the in-app prompts. The app will ask your phone to join the hardware's local network, which is typically named "TEG-xxx". Accept this request.
-
Once connected to the internal Wi-Fi, return to the Tesla app. Select your preferred home Wi-Fi network from the list of available networks.
-
Enter your home network password and tap "Connect".
-
It may take up to five minutes for the system to sync and confirm the connection to the internet.
