Yes it seemed that way to me and he did quote some 'infant" failures (eg failures quickly like yours). I'm just sad for you and discouraged about installing sp b/c even if I use a good company (not tesla) the inverter that is most used seems unreliable
Yes, it's been a bummer, I'm definitely in that infant mortality category. Day 13 of my Solar/PW outage, after failing less than two weeks after commissioning. Still broken.
However, I did just receive a text from my Tesla installation contact, with no information... other than to indicate that somebody will be out to look at the inverter this week. Not sure if they'll be ready and stocked up (replacement inverter) to fix it, or will just be diagnosing the issue on site. As usual, communication on the support/service side is cryptic at best. And again, on the sales/installation phase communication was actually pretty good, and surprisingly proactive. It's just not the case after they got my money.
One update I will add, is that I'm lucky this happened in the fall season. Despite my fears of being on a Demand charge rate plan, with NO solar or battery to offset my peak/demand period it's turning out to be not "too bad" cost wise. Because we're headed into the fall, our AC usage has dropped to to about 20% of what it is during the summer here in Arizona. Enough that I can pre-cool the house prior to the 2-8pm peak demand period, and pretty much cruise through that peak demand window with minimal AC usage. During the summer, a similar outage could have resulted in a total $500 electric bill for the month.
So taken together, with extremely cheap off-peak rates (3.6 cents/kWhr) I've managed to minimize peak demands. It still means instead of a $45-50 bill as I figured I would have for my October bill (SRP charges $32 base fee each month no matter what)... I'm still going to be around $90 for this months bill. So this extended delay is costing me, but I have to admit not as much as I feared just because the time of year this occurred, and because the cheap rates during off peak actually have more to do with reducing costs than Solar in my case, during the fall/winter months.
