Tesla PowerWall

Between installation and inspection, a part of my powerwall system failed, which shut off all power to my house for hours. Tesla came out and fixed it quite quickly, but then had to come out and do a more permanent job a couple of days later.

Last month the powerwall just stopped functioning. During the day when the sun was out, the app would say that all of my solar generated power was going directly out to the grid. However, my house continued to have power and the PowerWall continued to show it's level of charge. I called and they said they had to order a part. A week later and it just started working again. A week after that they called and said the part was in. I said it was already working, but they could install the new part for free if they wanted.

The tech comes out and says he's going to add a hard wire connection between two pieces of equipment that are less than a foot from each other in the setup for the Powerwalls, and which normally communicated for some reason via wireless. Zimba I believe he said.

A couple of hours later, and a short power outage and everything was back up and running.
