I don't know how this would work in Hawaii (yet) but in my place in the Philippines I have my system set up this way. I just use a double throw/double pull switch to change between grid power and solar power. If the battery bank gets low I can just throw the switch to grid power (if it's not during a frequent brownout). Or at night if I want to keep my refrigerator and fans running on a hot night, I can do that. I can't charge my batteries with the grid power though.
