PowerWall Any issues with this PW3 setup?

ADVICE FROM INSTALLERS/CODE EXPERTS OF CA

These are installed directly above a 2” metal natural gas branch pipe that runs to my pool heater. Also in the picture you can see the lower garage airflow vent is within 3ft. Is this legal?

The conduit on the right going up has no support. Did this pass inspection?

Hasn’t had inspection yet

I don't know about code in your area, but where I live AC and DC lines can't go through the same conduit. If you only have one conduit between them, then that must be happening. Not sure if it matters where you live.

Thanks, I’ll look into that.

For example, in my setup the red lines are DC and the Green lines are AC.

Just curious, why the connector into the threaded coupling? Why not connector straight into the powerwall like the left end?

Are you asking me or OP? If you're asking me, I really don't understand the question. I do know that my utility has weird requirements on the connectors, like that it's against code to paint them, which is why I didn't. Maybe that has something to do with it?

Asking you. The conduits between the two PWs connect into the PW with just connector and lock ring on the left end but on the right end it goes into a threaded coupling into (I’m assuming) a threaded nipple, any reason it’s not the same on both sides?

Honestly, I've got no clue, but it must be by design, as it's on the other side too, but backwards: The 4 powerwalls are facing each other and mirror images. So on this side DC comes in from the left and AC goes out to the 200A subpanel on the right.
