Plan Internet Connection for Solar Inverter

Lack of internet connection may impact product warranty. Consult the warranty to confirm requirements and impact. For best performance, ensure a Wi-Fi connection is configured during commissioning.

For Tesla Solar Inverter with Site Controller (Tesla P/N 1538000-45-y), an Ethernet connection can be established:

- 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 Ethernet Port for the position of the Ethernet port.

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