Before my install day, I was never asked where I wanted my Powerwalls mounted (5/2020 order, 6/2020 install). I first learned that my Powerwalls were going to be installed outside on the wall by my meter during an on-site home assessment from a site survey employee of my local Tesla Energy office. This was
after Tesla already had permits for my job. My order and install went months faster than I was expecting, so maybe I should’ve pushed for more details the various times I called in with other questions.
I asked the employee performing my site-survey if I could put my Powerwalls in my garage, on the opposite side of the wall that my design had them going. He included my request in his notes but told me that sometimes the notes that they put in from a survey are never read or followed up on. He said in the worse case I could discuss it with the crew on install day, and usually they can install them like I wanted it despite the design specifying otherwise.
To my surprise, I received the same notice as the OP the very next morning (Wednesday) after my site survey and the install date was for the following Tuesday. Shortly after, I received a call from a scheduler asking if they could move my job up to the next day (Thursday), only 2 days after my site survey. The scheduler told me that any notes from my site survey the day prior were already reviewed and they viewed my job as a simple one that didn’t require any re-design as a result of the site survey. I should have tried to get a concrete answer (from who, I don’t know) on where the Powerwalls would be going.
The next day the 2 crews showed up (solar panels and Powerwall) and reviewed the design plan before starting their work. The Powerwall crew lead showed me where they would be mounting the Powerwalls outside. I asked him if he could put them inside on the opposite side of the same wall and he said no problem. He told me that the warning of a $2,000 fee applies to more difficult late requests like if I wanted the Powerwalls on the back exterior wall of my home as opposed to the side wall towards the front corner of my house.
My inspection was performed virtually due to my county’s COVID policy. I don’t know if they passed my inspection via my original design with the Powerwalls outside, or if Tesla updated something so that my inspection considered that the Powerwalls are actually in my garage.
