Plan Internet Connection for Backup Gateway 2

Internet connectivity is required to receive the full 10-year Powerwall+ warranty, and for the customer to see their system in the Tesla App. When Powerwall+ is installed with Backup Gateway 2, the Backup Gateway serves as the system's Site Controller, meaning Backup Gateway is connected to the internet rather than Powerwall+.

Note
Do not attempt to connect Powerwall+ to the internet. Backup Gateway should only be installed with Expansion Powerwall+, meaning only Backup Gateway can serve as the connection point.

For best performance, ensure Ethernet and Wi-Fi connections are both configured during device setup. Backup Gateway will automatically select the network option with best connection.

Cellular is available only as a backup connection when Wi-Fi and Ethernet connections are lost. Cellular should not be relied on as the default connection method.

Install Ethernet Connection

  • Ethernet cable must be CAT5 (24 AWG) cable at minimum.
  • If it is not possible to run an Ethernet cable directly to the customer’s network router, Powerline Ethernet socket adapters may be used.
  • See Backup Gateway 2 Wiring for the position of the Ethernet port.
