When I was talking to support yesterday, they gave me an input about folks who call and say there batteries drained. But they swear they were not using anything in the house. But guess what, they had an electric spa and it was running pulling LOTS of suds. Another example was an on demand water heater that was set to max and pulled 11kwh when on.
So, as I am now playing with my system to simulate power outages, finding things that I had never thought about. And so many folks have NO idea what is running in their homes, and how much power they take, until they drain their batteries, call support, and complain its a tesla issue.
