Sounds like per the usual, the big failing of Tesla in general is just their communication.
Yeah, at some point you would think it would cost them enough money that they would fix the communication issues. Here, they had two inverters routed to the job site. In my case, they installed the wrong panels, then had to pay a crew to come out a second time to install the correct panels at a later date. I had to have my design redone several times due to miscommunications internally, so extra hours charged by the engineers. All that adds up over time, and I can’t imagine our cases were that unusual.
