Jeff, yeah you are very right. I found a 600 watt for $100 that I'm going to try,its worth $100 to see if this idea works. I normal have 350-600 watts of things running when the sun is shinning anyway. That should make sure I never send power back to the grid. I'm going to put a timer on the heat pump hot water heater to only run during those times as well. This by no means is a perfect setup. But that cheapest route to use the equipment that I have just laying around. I have a meter on my house that I can use to see how much it is really helping.
