Unless I missed it your not installing air conditioning, is that correct? Those of us who live in the south east USA (Florida, Georgia, Alabama, Mississippi) pretty much consider A/C mandatory. I know where you live it usually does not get as hot or humid as it does for us. I really like your idea of barely using the generator, mostly relying on the solar to keep your house batteries charged. I'm not sure that we could do that here in the south east. The energy draw of even a single A/C unit would probably require so much battery bank (To run all night) that it would be impracticable, and so many square inches of solar panels it would not be possible because you would need more sq/in than the total of your roof. I do remember seeing a link in a thread recently, (Might have been this one) where somebody was asking about a unit intended for RV use that is roof mounted and looks similar to a "Normal" RV A/C unit but is actually an evaporation or "Swamp cooler". They use far less electricity than a compressor driven "Normal" A/C system but with the high humidity in our region, they are all but useless for decreasing the air temperature so where we really need it, they are not a viable option.
Another quick comment on the A/C. If I had expected to spend much time South (including international destinations) or East, I would've gone with a 12 or 24V DC unit and it would've been a bigger priority in the design. There are a number of product offerings in the 5,000 to 7,000 btu range that would get the job done with a decent battery bank. I also did some testing last summer with a couple of the "Swampy" 12VDC evaporative coolers. They did fine in Utah's climate in a small space. I never tested the larger rooftop evaporative products because of the "splash factor". If we end up in a situation where we need to run A/C all night, my electrical system has an automatic generator start (the inverter/charger, charge controller, battery monitors, and control panel all communicate using the "Xanbus" protocol), so if we're not plugged into shore power and the batteries are down to where the inverter can't support the loads, the generator will kick on automagically.
