To run the A/C you will need either shore power or a generator no matter which way you go.
My thinking when I picked my direction was that:
A. Inverter technology has come a long way in the past 20 years.
B. Running a dual A/C D/C system is double the work
C. Residential appliance and fixtures are as a rule cheaper than RV/marine dedicated units.
The single down side in my opinion is that I give up about 10% of my battery capacity to inverter overhead.
I use a modified sine wave converter, two years now with no ill effects to any of my devices or appliances.
The switches on my transfer switch look like regular household light switches, albeit with three positions. (They don't show well in the dark photograph)
The fact that I am opinionated does not presuppose that I am wrong......
