I'm midstream in the process of having Power Walls installed onto my existing 17KW solar system. I'm hung up in the design process and have encountered the bad internal Tesla communication between customer service, engineering and operations ( installation). I originally asked for 3 PW2 installed to match my 3 solar system groups ( SunnyBoy 7000 #1, SunnyBoy 7000 #2 and 18 Enphase ). I wanted this because I'm in Northern CA and PG&E shut off my power last fall tiwce for 4 days each. I want to be able to store enough power during backup to run the next day with some margin for lousy days. But the engineer said it could figure out how to do it and designed a 2 PW2 system. They began the install process but I asked if they could take another look and try to do a 3 PW2 system aligned with my 3 solar inverters and power production.
I still over produce in the summer but I should be able to store most of my late fall and winter production. I've measured my home power with me being careful and I use on average about 24KWH/day. 3 PW2 will give me up to 14.5x3= 43KWHrs which seems comfortable. My winter production exceeds the 3 PW2s capacity of 43.5KWHrs.
Then everyone at Tesla disappeared for about 2 months and the customer service person I then got knows nothing about PW2s, power or installs. He cannot answer any questions. Its absurd. I was worried the 'new" engineer he said was on my project did not know all the issues. They kept asking me if I wanted my well pump backed up and that was a hang up. I told 3 different Tesla people that I don't use the well for home water and it doesn't need to be backed up as I told the first engineer. My customer service person said he was told doing so would make my 3 PW2 system "more streamlined". I asked what does that mean? Then they scheduled a site visit which I thought was great so I could explain what I had.
The day of the site visit came and went and nobody showed standing me up for 4 hours on a Saturday 2 weeks ago. They said they were sorry and said it would be this last Monday. That was the last I heard and nobody came called or emailed me yet again. I begged to speak with the engineer and was told Tesla doesn't do that. I told him I spoke with the first engineer 3 times. So he arranged a call with the new engineer who told me that the well was the only thing not backed up and doing so would make things easier. I told him about my pool at 50AMPs which "is not backed up" and he said "oh". So he said he would start over and now he knew why the I kept saying no to the well since it doesn't provide drinking water. Nobody talks to anyone.
Sorry about the long story. Does anyone have a good Tesla contact email where I could straighten this mess out. Since my Tesla contact doesn't know anything about engineering, communication, Electricity, PW2s, install requirements or schedules, he is useless. His lack of understand leaves me begging to speak with someone who understands minor details like the pool and why a "streamlined design" means nothing but there must be some important hidden misunderstanding that needs to be found. I'm concerned about installation issues since I built a wall near my PG&E service entrance, sent them photos but I haven't a clue if its ok and I've been stood up twice with site visits. Tesla is in big trouble if this kind of thing is happening to everyone.
I added a photo of my 7'x7' installation to see if anyone here sees any issues.
thanks
