Reconnecting your Gateway

Configuring Powerwall Wi-Fi Connection

Next Steps

Initial Steps

  • Ensure Correct Wi-Fi Connection: All connections require a 2.4GHz home internet connection. If your current internet plan and router only allow 5.0GHz connection, contact your internet provider to resolve this issue.
  • Wi-Fi Strength: Ensure that the connection to your system is strong enough to operate. If your connection isn't strong, you may need to consider the use of a Wi-Fi extender. There are two methods of testing your connection:
    • Quick Method: Seeing how many bars of internet connection your smartphone or tablet receives when standing next to your system.
    • Accurate Method: Measuring your connection strength via website or app. We personally recommend using WiFiman by Ubiquiti.
  • Downloading the Tesla App: If you haven’t already, download and install the Tesla app on your smartphone or tablet from the App Store or Google Play Store. If you don’t know your login credentials, please raise a support ticket with SolarHub and we will assist you.

Reconnecting your Gateway

Step 1: Locate Wi-Fi Configuration Page 

  • When you log into the Tesla app, you may be prompted to choose a tesla product. Select your Home Energy Site. 
  • Click on the ‘Settings’ tab and scroll down and select ‘Wi-Fi’ at the bottom of the screen. 

Step 2: Connecting to the Gateway 

  • Depending on the product you own, there are two different methods to reconnecting your system. 
    • For Gateway 1, click 'Manually Enter Wi-Fi Network' and use the serial number from your Tesla app as the password (ex. STG1…<serial>). 
    • For Gateway 2, click on "Scan for Networks" and scan the QR code located behind the glass door. 
  • If the connection fails, reset your Gateway, wait five minutes and try again. 
    • To reset Gateway 1, press the reset button behind the metal door for approximately one second. 
    • To reset Gateway 2, press the reset button behind the glass door for approximately one second.

Step 3: Connect to Home Network 

  • On your Tesla app, accept the request to join your Powerwall's local ‘TEG-xxx’ Wi-Fi network, where ‘xxx’ are the last three alphanumeric characters of your Powerwall serial number. Wait a few minutes for your phone to connect to Wi-Fi. 
  • Select your home Wi-Fi network, enter your Wi-Fi password and finally, click ‘Connect’. 
  • It may take anywhere between 2 – 10 minutes to connect. 

Configuring Powerwall Wi-Fi Connection

  • From the Home Energy Site main screen, open “Settings” and scroll down to “Wi-Fi". 
  • Select the Wi-Fi network you would like your Powerwall connected to and enter your network password. 

Next Steps

When reconnecting your battery and gateway back to the internet, your home data may be delayed. In majority of cases, your system should communicate back to your home monitoring relatively fast. If this isn't the case, give the system 24 hours to reconfigure and the issue should be fixed.

If this process is unsuccessful, raise a support ticket with SolarHub’s Support and Service Team for further assistance.
