Connecting Powerwall to Wi-Fi

Connecting to Wi-Fi provides your Powerwall with a more stable connection to Tesla. With the Tesla app, you can configure the Wi-Fi settings of your Powerwall+ or Powerwall with Gateway 2. You can also update your network settings if you change your router or update your network connection. Your Powerwall is supported on 2.4 GHz networks with WEP/WPA1/WPA2 personal security as well as hidden SSIDs.

There are two methods for your Gateway to connect to or update your Powerwall’s Wi-Fi connection. The app will automatically select the connection method depending on your Powerwall’s internet connectivity.

If Powerwall is Disconnected from the Internet

Your Powerwall will always attempt to maintain an internet connection. However, it may disconnect from the internet if your Wi-Fi network has changed or if the local cellular network has gone offline. When your Powerwall is completely offline, a ‘Device Offline’ banner will be visible on the home screen, and recent power flow or energy data will not be visible. To configure Wi-Fi, go near your Powerwall and Gateway, and follow the steps below.

Step 1: In the Tesla app, locate your home energy site.

Step 2: Select ‘Settings.’

Step 3: Select ‘Configure Wi-Fi’ at the bottom of the screen.

Step 4: Complete the following in-app steps based on your product configuration.

  • For Gateway 1, click 'Manually Enter Details' and use the serial number from your Tesla app as the password (ex. STG1…<serial>).
  • For Gateway 2, scan the QR code located behind the glass door.
  • For Powerwall+, scan the QR code located at the top of the enclosure.
     

Step 5: If the connection fails, reset your Gateway or Powerwall+, wait five minutes and try again. You must stand next to your system during the entire setup.

  • 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.
  • Refer to your Owner’s Manual for instructions on how to reset Powerwall+. If you are unable to reset your Powerwall, contact Tesla Customer Support.
     

Step 6: 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.

Step 7: Select your home Wi-Fi network, and then enter your network password.

Note: Powerwall is supported on 2.4 GHz networks,. 5GHz networks are not supported.

Step 8: Tap ‘Connect’ to connect your Powerwall to Wi-Fi. The connection may take up to five minutes to complete.

Note: Once connected to your home Wi-Fi, your Powerwall’s power flow and energy data will begin syncing with the Tesla network. If your device does not begin reporting data within 24 hours of connecting to Wi-Fi, contact Tesla Customer Support. If you are unable to connect your system to Wi-Fi, learn more about alternative internet connectivity options.

Troubleshooting

  • If the connection to TEG fails, reset your Gateway or Powerwall+, wait five minutes, and try again.
  • A Wi-Fi signal strength between two or three bars is required for successful connection to your home network. If a signal strength of two or three bars is not achieved, relocate your access point or consider alternative connectivity options.
