Well, after
months of calling and begging them to send somebody out, somebody
FINALLY came today as scheduled yesterday.
Armando from Tesla was here for about an hour, and I didn't want to get in his way, so I just caught a snap of his equipment:
He ended up having to take the entire inverter off of the wall mount to do the procedure. He talked about how he was the one who worked with the engineers to basically create/refine the process. They insisted that he could do it without taking it off the wall, and he kept telling them "Have you ever actually had to work on one of these things?"
Anyways, I caught the tail end of the procedure: he had the pump connected to one nozzle on the radiator, and another hose was connected to a different nozzle. He locked down the pour hole on the pump, and in doing so, some fluid came out of the other hose, which he then put into the white bucket to drain. I believe that's where he kept the extra coolant. Sorry, I didn't catch the brand. :-}
I guess this was after topping off, to ensure that everything was completely full.
After that, he reattached the inverter's hoses, and remounted it to the wall.
Based on what I saw I guess things could *technically* be done while mounted, but you'd need extension hoses for everything. Maybe that's why the engineers thought it was possible to do w/o taking it down. Oh, it occurs to me that the reason you'd want to lay the inverter down flat is because it'd be a pain-in-the-ass to remove/reattach hoses while it's mounted, as fluid would start spilling out everywhere. [
GRAVITY, who knew?]
At any rate, the great news is:
IT SEEMS TO HAVE WORKED!!
Since about 10AM, the system has been on and the app reports very reasonable (and
uninterrupted) output:
So very very excited that it's running as expected!
