The Tesla installer tested wifi reception and signal was fine. Installer said that the gateway is in this "new" inverter model is built in. There must be a LAN port somewhere (see pic of my inverter) as I may want to run a LAN cable at some point in the future. There is no separate gateway box and I don't have any powerwalls. Where is the LAN port? I am waiting on PTO from utility at present
Thx
