My Model S experience has been nothing short of stellar and I felt going in that my Powerwall project would be the same. For a time it seemed to go well and now it has crashed and burned. The utility co which seemingly makes its own rules on the fly is dictating the project and has been adding extra cost items and really horrid installation requirements. One of these would involve wrapping the house in conduit to place a “utility cutoff” on the front of the house. Not only would this look horrid but it is unnecessary and just bad engineering as it would create a permanent line loss by running all of my energy through an additional 100+ feet of wire.
That’s on the utility but Tesla never pushed back against this and included it in their drawings which I had to get from the utility co, as Tesla never provided them.
At this point, I’m communicating with different T people in different cities, none of whom will take ownership of this project or even communicate with me other than to put me off and say, “let me (find someone who knows something) and get back to you.
Having to get the drawings from the utility is pretty bad because I consider them the enemy. T is not advocating on my behalf, just quietly and without consultation with me adding idiotic design attributes.
T people have been nice and polite but they don’t seem to know what they are doing and are content to let the utility make a pig’s breakfast of this project and five figures worth of my money.
Communication from T has ceased so I guess it is up to me to start pulling the plug on this job. The utility clearly won here and that’s not entirely Tesla’s fault but assuring me all was going well while hiding major changes from me has reduced my opinion of the company. If they can’t do this, they need to exit this market.
Full disclosure: The conduit wrap referenced would go through a water heater cabinet with water and gas lines which is a no-no. Tesla never bothered to contact me to learn of obstructions and simply added this to the drawings which again, I had to learn about from the utility. I am less than pleased.
