You can see how excited I am to use the energy created by our pv solar panels. They had been charging the batteries for the last 48 hours. Solar power is a sort of use it or loose it thing. Once the batteries are charged up the panels energy will go to waste (unless some other load is in place). Today I shut off our grid power, turned on our solar power. I proceeded to run inside our trailer and turn on a air conditioner and swamp cooler. Now we are using our solar setup to its full potential.
