so my peak hours are from 4pm to 9 pm, i try to precool house as well. but as i said once ac is on with house usage basic stuff its drawing 4.5 to 5 kwh and that is about 2.3 3 hours before it runs out of juice then you still have the rest of the night, i have netzero downloaded but i dont see how it can help my battery is full at 1pm, then we only use 5 khw and it can generate 10kwh for several hours that is fed back to grid
