OK, sounds well researched. I have friends that spend their lives fixing alternators and buying more and more generating equip instead of fixing their fridges. I have 480W of solar and no genset or wind genny, I very occasionally need to run the engine, possible 3-4 hours per year for charging. For the T'stat, the start current of the inverter could be a problem, they have a big capacitor that charges, an Automobile 12V relay would extend the current rating. There is a company "R Parts" that has (expensive) electronic stats. There have been reports of short compressor life on fridge compressors used on inverters.
