Complete the Powerwall 3 Installation and Commission the System
Important Notes on Metering
- The only supported configuration
at this time is Powerwall 3 (single or multiple) with
Backup Switch / Backup Gateway 2 / Gateway 3
- Site metering is performed by Backup Switch / Backup Gateway 2 / Gateway 3
- Powerwall 3 performs its own Solar metering
- Solar metering for AC-coupled solar is performed by Backup Gateway 2 Meter Y (AC-coupled solar cannot be installed on sites with Powerwall 3 and Backup Switch or Gateway 3)
- Neurio meters are not supported at this time. If additional metering is required, it must be performed by a Tesla 100A CT connected to Backup Gateway
Connect Powerwall 3 to the Internet
Connect Powerwall 3 to the customer's internet router via either Ethernet or Wi-Fi.
Perform Device Setup in Tesla One
If needed, navigate to tesla.com/teslaone to install Tesla One, then enter Device Setup to commission the system. See the Powerwall 3 Device Setup commissioning guide for complete instructions.
Note
Ensure Tesla One is updated to version 7.9.1 or greater.
Note
Connect to Powerwall 3 to commission the system. Do not attempt to connect to Backup Gateway to
commission.
Install the Powerwall 3 Front Cover
- Install the air intake screen over the opening at the bottom of Powerwall 3, ensuring it snaps into place.
- Clean the front edge of the Powerwall 3 enclosure and the sealing gasket on the front cover.
- Install the front cover, securing the top (2X) fasteners first, then following
with the (4X) side fasteners. Torque all fasteners to 25 in-lb with a Torx T20
bit. CAUTIONMaintain pressure to keep the sealing gasket compressed until all fasteners are installed and tightened. If the sealing gasket is not compressed, the fasteners may thread form in the enclosure, breaking the front cover mounting tabs.
