Another fridge question

Interesting to note that the 9 cuft NovaKool fridge has the same outside dimensions as the 6 cuft Norcold absorbtion fridge.

We can easily handle the power for the 9 cuft compressor fridge if the Norcold poops out with 490W solar and 4 6V GC-2 batteries.

The OP is on grid power.

9 cu.ft fridge with a big freezer compartment - about 60-70 AH daily draw - is a lot of burden on 490W solar. In December in Mexico my 490W system barely harvests 30 AH on a dark day with some rain, and such days do happen sometimes. Probably would harvest 90 AH on a good day - which would still be marginal with 9 cu.ft. fridge. OTH, with propane fridge 90 AH is more than I need, batteries are full and floating all afternoon.

People "asking" about compressor fridges, especially fridges over 9 cu.ft, don't usually have solar and are don't plan on having one. They simply want a shore home experience - in a small box of trailer, which is hardly possible to achieve anyway, but this is what they and their family want :)

It is normal for compressor fridges (both 12V and 120V) to need less cabinet space than same volume propane fridge. The cost of 12V units with variable speed is about 3 times the cost of 120V units with fixed speed.

I was referencing the post from Copperhead which had to do with a mid sized compressor fridge which is what the OP was asking about.

5.2A(9 cuft) x 12 hr.(50% cycling)= 62.4AH. Maximum solar =26A x 4hr(mid day)= 104AH.(490W)
4.4A(7.5 cuft) x 12 = 52.8AH =18A x 4hr = 72AH (330W). I have not accounted for solar gain in the less than optimal hours of daylight.

Looks like, with our camping style, there shouldn't be any problems feeding a compressor fridge with our present set up if we replaced the current 6 cuft RV fridge with a 9 cuft NovaKool9000 unit.

Appologise to the OP if I got off topic.
