Thanks, I have enough to start now, but I am collecting more batteries right now. I have about 6000 watts of LiIon cells, with a goal of 21000 watts. I have 1500 watts of 24 volt solar panels, and I am working on the tracking system now. I will add another 1000 watts of homebuilt panels (I have the cells here already) to give me 2500 watts charge, due to the tracking efficiency. The heat and air unit I have located will draw 1800 watts. We will see, if it needs more power than I estimate, I will add more batteries. Local wind average velocities, will contribute about 450 watts / hour, from a 1700 watt wind generator I have already located.
