We are developing a 2000 sq.ft. home at an off-grid location in Hawaii. Due to the fact that most of the solar systems in Hawaii are grid-tie, our solar subcontractor does not have a terrible amount of experience with 100% off-grid systems utilizing batteries and a generator. I would be grateful for a little input on your end:
The system:
30 SolarWorld SW 280 mono panels
Outback GS 8048A inverter
16 Rolls S550 batteries (20.5 Kwh)
1 Generac 10kw generator
The house will have electric appliances (range, oven, dish-washer, laundry and dryer). We recognize this is not ideal, but plan on using these appliances mostly during the day-time (we are located on the dry side of the island with heaps of sunshine) and staggered (not running everything at once). Nevertheless, we will still probably use about 10Kwh of juice at night (dish-washer, tv, lights, etc.).
My main concern is the generator. I would like a system that supports the batteries anytime the load is at a certain level or if the batteries reach a certain point of depletion. Not sure if the Generac is ideal for this... Also, does the Outback GS 8048A include generator support? Or would we be better served with a different inverter.
Your input is greatly appreciated.
