@feld @mhoye I used to work for a power company and the only way they let you run your house on solar power was you had to have a big switch to flip between grid and autonomous. Then the problem was if you dropped below a certain level of usage, you got put on standby power which raised your rate, and made it not economical. but yeah it was set up this way because it was difficult at the time to prevent frying linemen when there was still a hot wire because of someone's house. Apparently this is figured out now though we just have to get the equipment switched which will take decades.
