Refrigerator draw on LP mode
I'm evaluating my total amp draw in order to properly size a new solar system with lifepo4 batteries and all that entails. My Fridge is a Norcold N821 2-way. The decal inside says it draws .8 amp...

Yes, I can read. (thank you!) Yes, absorbtion refrigerators ARE very efficient, (you are incorrect) that's why they are used in RV's in the first place. Ooops, ya missed that one didn't you?
Absorption fridges are quite a bit less energy efficient than compressor-based residential fridges (in terms of total energy use). The main reason they're used in RVs is that they use an energy source that is much more easily stored compactly: propane has a much higher energy density than electric batteries. A residential fridge will use somewhere in the rough vicinity of a third the power that an RV fridge will use if both are operated from AC power.
DC-powered compressor fridges are usually pretty efficient...and not all that inexpensive. Their DC consumption is higher than an absorption fridge's DC power use in propane mode, of course, since it's providing the actual energy to cool rather than just powering the controls.
