Well, I finally got our Total Energy Detective system up and running properly this afternoon. Had to do some final tweaks but it works. I may have some noise issues and may need to get a filter but over all it is doing well. I am going to get another set of readers and just check the garage usage. Pretty much the car is connected to the garage. If you want a good system The Energy Detective 500 is a good choice. You can monitor main solar and net and single circuits if you want. It is amazing how much power an electric water heater uses. Gotta get that solar hot water done asap. That alone will save a bundle. Even though we have solar we do use more than we make.
