Hi,
The only one I'd consider is the Platinum Cat. Very low power draw, but location is an issue.

Catalytic Heaters? No pwr draw.
One drawback to the cat heaters, mr. buddy etc. (or any unvented propane heat source) is that for every gallon of propane burned, you'll get an additional 3 quarts of water added to the interior air as a combustion byproduct. (CxHy= heat +CO2 +H20). Doing that every day for a week in colder weather could end up with moisture issues for you. Add this to the water vapor from the stove, oven, and persperation, and it can get out of control.
This was the reason I quit using a cat heater in my small 14' trailer in the winter.
Now, if the RH is very low, this may work and function as a humidifier.
Not an issue with a vented flame such as a furnace or WH since the combustion air is vented outside.
FWIW we can go 3-4 days w/o any solar, generator etc. quite comfortably in our trailer in cold weather (well, cold for the PNW, not necessarily cold for where you are) including running the furnace with 4 T-125 GC batteries, about 500AH, before I'm down to 50%SOC. With your 850AH, and solar, going a week may not be an issue for you even with running a furnace.
