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...

Chum Lee,
The absorption fridge in my class C uses 5.7 KWH per day (measured with a kill-a-watt meter). That is with an ambient temperature of about 68 f (20 c).
Running it from solar would require 1100 watts of panels and 4 SiO2 batteries (6 would be better).
It would use less 120 volt power to run a residential fridge.
Duty cycle is 2:3 (measured).
Thanks for your post. I do appreciate what you do. I am a professional paid engineer. (and a **** good one at that) I deal with reality everyday. When I say/suggest my solar panels generate 140 watts, I'm not talking about the manufacturers published wattage, I'm talking about what they actually do, . . . sitting here, right now. I keep track. Currently, I have 3-240 watt Kyocera panels flat mounted on the roof, an MPPT controller and a 1000 watt PSW inverter. I'm not giving away all the details of what I do to make it work. Hire me if you want to know.
