Quick Guide: Commissioning Powerwall 3 or Powerwall 3AC in Tesla One

Note
Unless otherwise specified, any step referring to 'Powerwall' is applicable to Powerwall 3 or Powerwall 3AC. Steps that apply to only one Powerwall model are explicitly called out, with colored borders around the Tesla One screenshots for added clarity.
  1. Launch device setup in Tesla One:
    1. Launch the Tesla One app and log in with your Tesla Partner Portal account credentials.
      Note
      See Install / Update Tesla One for instructions to install Tesla One if it has not already been installed on the commissioning phone.
    2. Select Begin Install > Scan QR Code.
    3. Scan the QR code on Powerwall to join its Wi-Fi network and launch device setup.
  2. Configure the internet connection:
    Note
    • Internet connectivity is required to receive the full 10-year Powerwall warranty, and for the customer to see their system in the Tesla App.
    • For customers without a strong Wi-Fi connection, ensure that Ethernet is connected.
    1. Select Networking > Wi-Fi.
    2. Select the customer's Wi-Fi network to connect.
    3. Select Test Connection to verify that Powerwall is connected to the internet.
  3. Check for Powerwall software update and install if available:
    1. Select Software > Check for Update.
    2. If an update is available, select Perform Update and choose either Download on my phone (if this option is available) or Download on the Tesla device.
      • Download on my phone or sideloading allows you to download an update to your commissioning phone rather than directly to Powerwall. This method saves time, as cell phones generally have a much stronger and more reliable mobile connection, allowing for a faster download. The update downloaded on your commissioning phone can also be used repeatedly, meaning no software download is required until a new software version is available; at that time, the new update can be downloaded to the phone.
        Note
        If this option is not available, select Download on the Tesla device.
      • Download on the Tesla device allows you to download an update directly to Powerwall rather than to your commissioning phone. This method is often used when Powerwall is connected to the Internet via customer's Wi-Fi or Ethernet.
      Note
      To learn more, see the Update Powerwall 3 Software.
    3. Follow the onscreen prompts to download the software update.
      Note
      Wait for the update to be downloaded and installed. Powerwall will reboot and a Lost connection to Tesla Energy Gateway message will display; connect to Powerwall again and select Software to confirm the update was successful.
  4. Select System > Devices to check the connected devices.
    Note
    The Devices page must display all devices; if a device does not appear, check the communication wiring for errors.
  5. Powerwall 3 : Configure maximum power / current output:
    1. Select System > Devices > Powerwall 3 > Max Current Output.
    2. Select the desired maximum current / power output from the dropdown menu.
    3. Select Confirm Max Output > Reduce Current Output.
      Note
      Once the setting has been confirmed, it cannot be changed by the installer. Contact Tesla Support if the setting must be changed.
  6. Configure energy metering:
    1. Select System > Metering.
    2. Select Gateway Primary Meter X and select what the CTs are measuring from the Location dropdown. If the CTs are not measuring anything, select None.
      Note
      Meter X has a CT for each conductor (i.e., CT1 for L1, CT2 for L2, and CT3 for L3).
    3. Select Gateway Secondary Meter Y and select what each CT is measuring from the Location dropdown. If a CT is not measuring anything, select None.
    4. If necessary, follow the onscreen prompts to complete the configuration of energy metering.
  7. Configure settings:
    1. Select Settings > Grid Code and choose the Country, Region, Distributor, and the grid code standard, and ensure that the Voltage/Frequency selected for the site is correct.
      Note
      If a dropdown menu does not have the desired option, select All Other or select the option that most closely resembles the desired region.
      Note
      You cannot change the grid code while the system is running.
    2. Powerwall 3: Select Solar Installation Type to choose from one of the below options:
      Note
      Powerwall 3AC is a storage-only device, meaning PV strings cannot be connected (at present or in future). If PV strings are connected to Powerwall 3AC, it will shut down and the following alert will be displayed until the PV strings are disconnected.
      • Select Solar Panel when the customer's house has solar panels installed on top of the existing roof.
      • Select No Solar if solar is not installed.
      Note
      This field is required so that Powerwall functions properly, and so the Tesla app uses the correct graphics.
  8. Powerwall 3 or Powerwall 3AC: Assign backup phase:
    1. Select Settings > Phase Detection > Detect Phase.
    2. In case of single Powerwall, ensure that the phase assigned to the Powerwall is selected as a Backup Phase.
    3. In case of multiple Powerwall units, ensure that each Powerwall has been correctly assigned to the phase it is physically installed on. If the Backup Phase selected is incorrect, select the correct one from the Backup Phase dropdown.
    4. If a Powerwall's phase is undetected, check the alerts tray to determine how to proceed, and run phase detection again if necessary.
  9. From the landing page, select Start System and allow devices to update and self-test. You can select System to view the progress. Once all devices are updated and self-tests are completed, you can see a green check mark next to each of the devices.
    1. If solar is connected, select Powerwall 3 to ensure that the solar inverter is active and solar is producing.
  10. Complete system registration:
    1. Select Registration > Installer Info and enter your contact information.
    2. Select Continue to proceed to the customer registration.
      Note
      Customer registration will fail if the system is not running. Ensure the system is running before trying to register it.
    3. If the customer is available, select Show a code or Text the customer to allow the customer to enter their information. Both of these methods open the Tesla app to the Add Products page; the customer can also navigate to Add Products manually. See Registering Your Powerwall for more information.
    4. If the customer is not available, select Customer is Unavailable and complete the registration form on their behalf.
      Note
      The customer email address entered during registration is the link between the product and the customer's Tesla account. Please ensure that the email address is entered correctly and is the one used by the customer for their Tesla account.
    5. Select Done to return to the landing page.
  11. Resolve any alerts displayed at the bottom of the page.
    Note
    See Address Alerts for more information about resolving system alerts.
  12. Perform backup test:
    1. Select System Tests > Backup Test, select the system configuration from the Backup Type dropdown, and then select Begin Backup Test.
    2. Monitor the system as the backup test progresses. If the solar is not installed and the integrated DC isolator is in its Off position, select Solar is not expected.
    3. If needed, select Reconnect To Grid to end the test.
    4. Once the test has successfully completed, select Done to return to the landing page.
