Connecting to Tesla Gateway and Powerwall+

If you lose internet or cellular connection, view instructions on how you can monitor your system’s power flow and charge level through your web browser by connecting to your Gateway or Powerwall+.

Connecting to the Network

1. Find your password.

For Backup Gateway 1 and Non-Backup Gateway, your serial number (found in the Tesla app) is also the password.

Note: If you enter your password manually, it begins with the letter S. If the serial number on the sticker does not begin with the letter S, you must add the letter S before typing the serial number (e.g. STG123456789123).
For Backup Gateway 2, your password is located behind the door of the unit.
For Powerwall+, your password is located on the back cover of your owner’s guide.

Note: If you do not have your owner’s guide, you can find the password on a second sticker inside the Powerwall+ solar assembly enclosure.

To find the password inside the Powerwall+ solar assembly enclosure, follow these steps:

1. Turn off Powerwall+ by turning the switch on the side of the unit to the OFF position.

2. Turn off the Powerwall+ AC breaker.

3. Wait at least 30 seconds for the system to de-energize.
Note: Double check and confirm Powerwall+ has been powered off by checking the LED on the side of the unit. If the LED is off, it is safe to proceed.

4. Using a right-angle Phillips head screwdriver, loosen the captive fastener on the Powerwall+ solar assembly door.

5. Lift the door latch and the door to open the enclosure.

6. Take a photo of the password sticker.

7. Close the door, ensuring it latches shut.

8. Using a right-angle Phillips head screwdriver and tighten the captive fastener on the Powerwall+ solar assembly door.

9. Turn on the Powerwall+ breaker.

10. Turn on Powerwall+ by turning the switch on the side of the unit to the ON position.
Note: If your system contains the Tesla Solar Inverter, view how you can connect to Tesla Solar Inverter.

2. Connect to your local system network.

Open Wi-Fi settings from your mobile device and search for a network named “TEG-xxx” where xxx are the last three digits of the Gateway serial number. You will use your Gateway password to connect.

Note: If you are unable to connect, try following the instructions for connecting Powerwall+ with Backup Switch. If the TEG network you see matches the Powerwall+ serial number rather than the Gateway serial number, proceed to connect to the Powerwall+. If you do not see any TEG Wi-Fi network, ensure the system is powered on. If you still do not see any TEG Wi-Fi network, or if you do not see a TEG Wi-Fi network that matches any component in your system, contact us.

Note: If you experience trouble connecting to the network on a phone, turn on airplane mode, then turn on Wi-Fi and connect to the system’s Wi-Fi network. This prevents your phone from disconnecting from the Wi-Fi network or attempting to use a cellular connection.

How to Sign In

1. Open a web browser and enter any of the following in the address bar:

https://192.168.91.1
For Powerwall or Powerwall+ systems
- https://teg
- https://teg-XXX

Note: Turn on airplane mode then turn on Wi-Fi and connect to Tesla Gateway or Powerwall.

2. When connecting to Powerwall or Gateway for the first time, your browser may present a privacy warning. Proceed past the privacy warning and accept the site as safe. To do this, look for 'Advanced' or 'Show Details' and then click 'Proceed to' or 'Visit this Website.’

This privacy warning is shown because each Powerwall or Gateway has its own self-signed SSL certificate to support a private connection. These certificates are not pre-registered to be recognized by the browser or certificate authority. Once you accept the site as safe the first time you visit, it will save the certificate to this computer for future use.

3. Once the page loads, click ‘Login.’

4. Choose the ‘Customer’ sign-in type.

Email: Use the email you use for your Tesla Account.
Password: The first time you sign in, your password will be the last five characters of the password identified in Step 1 under Connecting to the Network.

5. Your password can be reset or customized by tapping 'Change or Forgot Password' and following the on-screen instructions.

Update Network Settings

Once you are signed in, follow these steps to change network settings:

1. Select 'Network.'

2. Select 'Wi-Fi.'

3. Select your home Wi-Fi network and enter your password. For Backup Gateway and Non-Backup Gateway, Wi-Fi network will briefly stop broadcasting while it scans for Wi-Fi networks.

4. Wait two minutes and rejoin the Gateway’s Wi-Fi network.

5. Refresh the page.

Backup Gateway and Non-Backup Gateway are only compatible with 2.4 GHz networks. If you have a dual band router that broadcasts 2.4 and 5.0 GHz networks, for all Gateway types, we recommend selecting the 2.4 GHz network.

The Gateway does not support Wi-Fi connection to Enterprise networks requiring a username or to networks with a Captive Portal sign-in.

Note: Our Customer Support team will be unable to assist with network configuration. If your Powerwall or Gateway is not connected to the Internet for an extended period of time, or has not been registered with Tesla, we may not be able to provide important remote firmware upgrades. In these circumstances, we may not be able to honor your full Limited Warranty for your Powerwall or Gateway. Review your Limited Warranty for additional information.

Monitor Power Flow and Charge Level

Once you have signed in, you will be able to monitor your power flow and charge level. This will be useful if you have lost connection to your Tesla app and want to know the status of your Powerwall.
