Why Tesla Powerwall Stuck In Standby Mode? (With Solution)
Problem 1: Weak or Unstable Connectivity
If the distance between the Powerwall and your router or access point is too far away or there are obstacles in between, the Wi-Fi signal might be too weak or unstable.
This can prevent the Powerwall from connecting to Wi-Fi or cause frequent disconnections.
Solution
Make sure the router or access point and the Powerwall are close to each other and there are no obstacles in between.
You can test the signal strength using your phone or another device near the Powerwall. If the signal is weak, you may need to relocate your router or access point, use a Wi-Fi extender, or consider alternative internet connectivity options.
Problem 2: Powerwall Not Commissioned Properly
If the Powerwall is not commissioned properly, it might not be able to broadcast its own Wi-Fi signal or connect to your home Wi-Fi network.
This can happen if the Powerwall is not installed correctly, the commissioning process is interrupted, or the Powerwall firmware is outdated.
Solution
To troubleshoot the Powerwall and ensure that it is commissioned correctly, you need to go near the Powerwall and Gateway, and follow the steps below:
1. In the Tesla app, locate your home energy site.
2. Select ‘Settings.’
3. Select ‘Configure Wi-Fi’ at the bottom of the screen.
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.
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+.
6. Accept the request to join your Powerwall’s local ‘TEG-xxx’ Wi-Fi network, where ‘xxx’ is the last three alphanumeric characters of your Powerwall serial number. Wait a few minutes for your phone to connect to Wi-Fi.
7. Select your home Wi-Fi network, and then enter your network password. Note: Powerwall is supported on 2.4 GHz networks. 5 GHz networks are not supported.
8. Tap ‘Connect’ to connect your Powerwall to Wi-Fi. The connection may take up to five minutes to complete.
Problem 3: Wi-Fi Security Not Set Properly
If the Wi-Fi security settings of your router or access point are not compatible with the Powerwall, it might not be able to connect to Wi-Fi or authenticate successfully.
This can happen if the Wi-Fi network is hidden, has a complex password, or uses an unsupported encryption method.
Solution
Make sure the Wi-Fi security settings of your router or access point are compatible with the Powerwall.
The Powerwall supports 2.4 GHz networks with WEP/WPA1/WPA2 personal security as well as hidden SSIDs.
If your Wi-Fi network does not meet these requirements, you may need to change the settings of your router or access point, or create a separate network for the Powerwall.
Alternatively, you can use a wired Ethernet connection or a cellular connection to connect the Powerwall to the internet.
Additional Troubleshooting Tips
If none of the above solutions work, you can try the following tips to fix the problem of Tesla Powerwall not connecting to Wi-Fi:
1. Check the Wi-Fi settings on your phone or device that you use to connect to the Powerwall. Make sure the Wi-Fi is turned on and you are connected to the same network as the Powerwall.
You can also try forgetting and reconnecting to the network, or restarting your device2.
2. Check the status of the Gateway and the Powerwall on the Tesla app. If the Gateway is offline, you may see a grayed-out or blank power flow screen.
If the Powerwall is offline, you may see a red exclamation mark on the battery icon. You can also tap on the battery icon to see more details about the Powerwall status.
3. Check the LED light on the right side of the Powerwall to determine its status. If the LED is on (solid), it means the system is idle and has no faults.
If the LED is on (fading), it means the system is enabled and charging or discharging. If the LED is on (flashing), it means there is a fault present. If the LED is off, it means the system is not enabled or switched off.
4. Check the wiring and connections of the Powerwall and the Gateway. Make sure they are secure and not damaged.
If you see any signs of heat damage (smoke, burning smell, or any other signs of burning), do not touch the system and contact Tesla Customer Support.
5. Check the firmware version of the Powerwall and the Gateway. You can find the firmware version on the Tesla app by tapping on the gear icon and selecting ‘System Information’.
The latest firmware version as of December 2023 is 21.40.3. If your firmware version is lower than that, you may need to update it manually or wait for the automatic update.
6. Check the Wi-Fi network name and password. Make sure they are correct and do not contain any special characters or spaces.
You can change the Wi-Fi network name and password on the Tesla app by tapping on the gear icon and selecting ‘Configure Wi-Fi’. You will need to scan the QR code on the Gateway or the Powerwall to connect to their local Wi-Fi network.
7. Check the Wi-Fi signal strength and interference. Make sure there are no other devices or appliances that may interfere with the Wi-Fi signal, such as microwaves, cordless phones, or Bluetooth devices.
You can also try changing the Wi-Fi channel or frequency on your router or access point to avoid congestion or interference.
