Plan Internet Connection for Powerwall

Internet connectivity is required to receive the full 10-year Powerwall warranty, and for the customer to see their system in the Tesla App.

Cellular is available for commissioning and as a backup connection when Wi-Fi or Ethernet connections are lost. Once Powerwall has been registered to the customer, they can configure a Wi-Fi connection using the Tesla app. For customers without a strong Wi-Fi connection, install an Ethernet connection as follows.
