Well done ... what was the installed cost?
Here's my dual HPWC install with a backup 14-50 (just in case something takes out the 'electronic' devices). The interesting thing installed as part of this was a gadget my electrician used to ensure that the subpanel only had either the 100 Amp circuit for the HPWCs, or the 50 Amp circuit for the 14-50 active at one time.
I'd never seen such a simple method of keeping only one breaker on at a time, but this works (I assume, haven't had the inspection yet!) and also would serve as the lockout, as there's a place for a small padlock to keep the 'flipper' from moving when it's set to one side or the other.
Details on the installation: The conduit going up and to the left goes to the main 200 Amp panel; the junction box at the upper right is where the 100 Amp circuit from the subpanel uses three-way taps to break off to feed one of the HPWCs below, and then also goes to the conduit at the top of the junction box to go up over the ceiling to the other HPWC on the other side of the garage. The load-balancing data cable goes between the two HPWCs directly in the same conduit.
(The other 'object' crossing over the conduit is the garage door track.)
Another fact I learned that was interesting is that Tesla Certified Electricians are required to submit photos of their installations back to Tesla to show that everything was done correctly.
I also used the 'Gecko Toes' devices (which I saw elsewhere on TMC) to hold the 25' cables. They work excellently; if you get these (available at Amazon), be sure to get the ones for 'water hoses', and not air hoses or extension cords.
