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 best performance, ensure Ethernet and Wi-Fi connections are both configured during device setup. Powerwall+ 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 not possible to run an Ethernet cable directly to the customer’s network router, Powerline Ethernet socket adapters may be used.
• See Powerwall+ Wiring for the position of the Ethernet port.
