Been playing around with ideas for my (soon to be built?) house. I think I am close on the plan, but the components are still up in the air. Not sure if I can get Growatt grid tie approved with my provider. Any comments welcome. The main grid tied panel will be non-essentials, and the two sub panels will be essentials. It is a single house with two living areas (approx 2400sqft ranch 40'x60'), Central Texas, South West facing roof (211°) 27° pitch, 5 hours of sun. 40-50kwh usage per day.
