Here's a mini split which is designed to be driven directly from solar panels with or without grid tie. If it has grid tie, which could well be your battery bank/inverter, it will use it only to supplement solar as needed. Seems like a pretty nice alternative.

For the price it would be worth a look.. I think this might be a great find Chuck ^.^d
With two ACs off the roof, there would be room for more solar panels.
