I got 9.8KW solar system installed and became operational in September 2019. I paid in full. Three weeks into production, Tesla app showed error message " Graph data unavailable". I contacted tech support. We couldn't resolve the issue over the phone so Tesla scheduled for Tech to come in after one week. Tech came in and determined that Hitachi inverter is fried and it needs to be replaced. Why the brand new, factory tested, inverter went bad?? Don't know.
I called them and was told it will be replaced in two weeks. Not bad.
I called again after a week to follow-up and I was told it will be 4 to 6 weeks. I said, that's not fair and tech support told me that I can get my money back in " performance review" time. I asked her when that will be and after going through my contract, she mentioned that I don't have it in my contract. Tesla didn't put that in contract and I was not even aware of this option. I got frustrated and ended the phone call.
I called again this week to get some timeline and I was told that they can't get the Hitachi inverter anymore so they are looking for another compatible inverter. Once they find it, it will be 4 to 6 weeks after that. UNBELIEVABLE! Although she sympathized with me on my situation, she couldn't do anything about it.
I am also a proud Tesla model 3 owner and that was the reason to stick with Tesla for solar panels but I regret this decision.
