They use Hawaii since there is a great mix of sun and also a lot of rain, especially with all the storms they have been having so the system gets rung out really well.

THAT sounds like a crock!
We build battery based systems. We can even link an existing grid-tie system to our battery inverter system. It is cheaper overall if you do the battery based system from the beginning.
Our latest offering is similar to an essentials circuit generator. The inverter output is connected to all 110VAC circuits, which never lose power. "intermittent" loads are operated only when the generator runs.
You gain the benefits of year round solar helping save money, but with the addition of a whole house UPS. Larger inverter banks are available which allow some or all of the high demand circuits on the "essential" side.
Installed in Texas, a 4000 square foot house with two 3.5 ton A/C units can be run with our smallest 220VAC Mi-Grid system, with a 20kW Natural Gas Generator. Installed cost is around $35K, but depends on distance to electric and gas lines. Permits are extra.
