Lots of good information here. Thanks everybody.
The last big gotcha: need to have a class 1 or class 2 ethernet cable that connects the gateway and powerwall, and if planning to but these in very far away places (e.g. gateway at the meter, and PowerWall in the basement where the solar inverters are for temperature control), run this or leave a conduit that you can fill later if you can do it without 360 deg of bends, etc. The Tesla installers use an ethernet cable that has a mains insulation rating so they can put it in the high voltage conduit. Note that you cannot just use regular ethernet cable even outside of a conduit since the instructions require class 1 wiring methods for the comms.
Do not make the mistake of thinking that sections of the code referring to communications refer to data transmission that is not associated in any way with a utility that provides voice or data distribution over a wide area.Code does not allow communications wiring to be installed in the same raceway as power wiring.
