Frustrated with Solar City
When Powerwall 1 was first announced, I signed up to be on the waiting list and never heard another word. In the interim, I had a solar system installed by a local company and paid extra to get the SolarEdge 7600AUS that was specified as the only inverter that would work with the Powerwall. I also had the company leave room in the closet with the inverters for the Powerwall.
When the Powerwall 2 was announced, I again signed up and put down the $500 deposit. I was finally contacted by Solar City to do their site survey. The guy who came out to do the survey knew absolutely nothing about the Powerwall and couldn't answer any questions and said all he knew how to do was measure and take pictures, which took him a couple of hours.
I then received the purchase agreement, which said the Powerwall could not be installed where I had asked them to, even though I know there is plenty of room for it next to the inverters. They said it would have to be installed next to the electrical panel and could not be wired into the inverter. They also said I need a Main Panel Upgrade for $1,900. When I called the number given on the agreement to question their proposal, I reached a "Legacy Energy Specialist" who said they were my contact and any questions I had would be relayed to engineering and they would answer within 5 or 6 days. So I asked my questions about the placement and need for the panel upgrade and the possibility of the Powerwall doing a whole-house backup if I handle the loads in the case of an outage. About a week later got an email stating that the only inverter that could be used with the Powerwall 2 was the Delta 7.6 inverter, which I had never heard of and is not listed on the Tesla Energy website, and that if I wanted to stay with my existing 200 Amp panel, in order to do whole house backup, I'd need three Powerwalls. They said only loads of 30 Amps or less can be backed up so that's why I needed the panel upgrade so they could install a load center and gateway to handle all of my 30 Amp and lower loads. I said I have a subpanel in the garage that is connected to the main panel through a 100 Amp breaker and all of its loads power everything in an addition that was added to the main house, so I asked if those loads would be included in the backup through the load center, and they couldn't answer the question. I again asked if I could speak to the engineer and was denied and told it would be another 5 or 6 days before I could get an answer.
I then asked about the possibility of going to another installer and was told that I could cancel my order with Tesla and start all over with someone else who would order the Powerwall from Tesla directly. That doesn't sound right, either. Has anyone else experienced this kind of response from Solar City? Any suggestions on how I should proceed? Thanks, and sorry this is so long.
