Our relationship with Tesla energy has gone badly sour. After an initial high quality install witnessed by our contractor – who himself does solar and who stated that the team that installed the panels and powerwalls was "a real A-team" – we had a second smaller 8 kW system installed in our rental property (Right next door to our new house) with again 2 powerwalls. Both systems worked flawlessly one installed in January of 2020 (12 kW) and the other in June of 2020 (8 kW) – until they didn't.
Everything seemed to be going again smoothly with that second system, until both systems went down on the same day, August 13, 2020. Somehow – and don't ask me how this works – a lightning strike on the back Powerline that feeds both houses took out the Gateway computers in both systems. But affected nothing else in either house. Nothing. How this might work from the standpoint of a lightning strike into a main power line – either pre-or post-house transformer – is not clear to me, And Tesla of course has no explanation either. Whether this reflects some unusual vulnerability of the Gateway system is also unclear. Tesla would not discuss whether or not this had happened To other systems (fried Gateway wiring status post lightning strike), claiming to not know . . . . or not have those statistics . . . . or it's above my pay grade, 1000 similar excuses. Not impressive performance for a technology company.
It took three months to get these two Gateway computers repaired, with Tesla changing, and canceling appointments several times, and giving me a different story every other week about parts and availability. I was initially sent the bill for this charging me for taking the solar panels off the roof, Reflecting the distracted service technicians erroneous cut and paste! I still have not gotten an accurate or intelligible bill with parts or labor itemized in a proper fashion.
I was able to inspect the wiring in the two Gateway computer systems and sure enough the lines in the computer that monitor the 240 grid voltage were fried and fused. I'm frankly still not clear how a single lightning strike took out both Gateway computers and did nothing else to damage electronics or wiring in either house but be that as it may, it was after the Gateway computer repairs that the real circus started. I thought getting the Gateway computers repaired would be the hard part – I was naïve.
The smaller system showed an error message that the powerwall circuit breaker needed to be reset. Of course that was not a problem, and one of the powerwalls simply became unresponsive sometime after the Gateway repair. I'm still not clear whether the powerwall worked briefly for a time or whether it never worked status post lightning strike. The person who did the Gateway computer repair who struck me as a competent technician came out and looked at the powerwall but couldn't figure out what was wrong, and admitted that they did not know. Somehow he communicated to Tesla that the Powerwall issue was "force majeure" and secondary to the lightning strike - as a proven fact and not as a hunch which is all it was.
I've spent literally an hour explaining to Tesla (and to the new rotating service technician du jour which changes week to week) that no one in fact has proven what is wrong with the powerwall and that there is no unambiguous evidence that it was damaged from lightning. From that point forward, Tesla did not want to repair the powerwall, or even send anybody out to diagnose it, but they were more than happy to sell me a new one for full price plus installation, and take the old one off my hands giving me nothing for the damaged or dysfunctional one. I said no thanks, and that I wanted an actual diagnosis of the powerwall and proof that it was damaged from lightning. They pretty much declined to do that and essentially are now refusing any assessment of the powerwall other than simply my anteing up $11,000.
Obviously, it's in Tesla's best interest to pawn off a warranty repair as force majeure if that indeed is what this is. I still don't know. Neither does Tesla. I've made approximately 30 phone calls, had two or three appointments made that were canceled for no reason. Customer service technicians routinely echo the non-proven assertion that the powerwall was damaged by lightning, and that Tesla is not responsible in any way for this – even to the point of denying diagnostic work to confirm whether or not in fact there is anything that looks lightning fried in the one powerwall that is off-line. I've communicated to them that we are very close to adversarial process. They seem used to hearing this and are not impressed.
I'm at the end of my rope and I really regret buying this second system from Tesla. Who else in the Florida area has had experiences like this with the Tampa crew in terms of powerwall issues? I'd like to join the class action if there are enough people who have had this kind of experience Florida Tesla energy.
Another option would be if there is a third party in Florida that actually repairs powerwalls. Tesla claims that they don't repair them they just replace them. I'm not even sure how that could be true. Like I said I don't trust anything Tesla says at this point.
