things are moving along now
The insurance company is deciding how little to pay. Looks like they want to pay for the damage done by the fire, excluding the cost of the cause of the fire, the cooling unit. Time for me to find a new insurance company.
David at Sea Freeze is in the loop. Looks like it will be a two door (top freezer) refrigerator every bit as big as the Dometic. This means too big for a DC powered Dan Foss compressor. The good news is that the AC Tecumseh compressor is more efficient, drawing only 1.6A when running. A couple of fans will be added, but this should still make it less than 2A. I'll need to either use the existing inverter or add a dedicated inverter. David says to go with 3KW to handle motor starts, but I think that would be way overkill. He also says these work with modified sine wave, but I believe it will be more efficient with a true sine inverter.
What remains to be seen is just how many Amp Hours of DC are used in a day. If it uses 2A for say six hours a day at 120VAC, this would be 120AH of 12VDC. My solar is on the fringe of handling this at the moment, peaking at 15A, but will improve when I add more panels. My goal is to be able to park the RV unused in the sun with the refrigerator running and come back a few days later with everything still cold and the batteries still charged. Camping, in the winter, running the LP furnaces, watching TV, using lights, ... I expect to run the generator on occasion.
