That's a bit of a pity about the bag.....

Tell me, is this fridge a 3 way or just a 12/240??

We had a fridge with no cover, my wife sewed 2 windscreen sun reflectors together to make a slip over bag.
Kept the vent areas free of course.
Free fridge ,what a bonus :+

I do hope he intends on going for a drive every day as the batteries in the car are only cranking batteries....not deep cycle.

How long are you camping for this time dea??

Here's a power consumption guide for an 80 litre fridge freezer running on 12 volts that could be used as a starting point in working out battery needs.

http://www.waeco.com.au/products.asp?id=14&subCatId2=69&subCatId=60&catId=57
Capacity: 80 Litres, holds 103 cans
Power: Av. Power Consumption: 2.9 amps/hr (@ 12V, 5°C fridge, -15°C (approx.) freezer, 32°C ambient temperature)


2.9 amps for 24 hours = 69.6 amp hours.

That is for a Waeco with a German made Danfoss BD-50F compressor whereas this one has a Acc/Zel Domus T32K compressor. So the Waeco specs quoted above may be totally irrelevant for this particular refrigerator.

Sounds to me like the guys have it pretty well sorted out with the vehicle dual battery and the extra battery on the camper.

You will soon work out how much use you will get out of your batteries.

I doubt very much that the current draw will be this low, probably more in the vicinity of 4 to 5 amps per hour when cycling.

Just make sure you are prepared dea and all will be great for you. You will have many fantastic camps.

I agree with using 4 to 5 amps as a realistic value to allow for.
It can't go over 5 amps according to the specs so that's a good worst case value.

I noticed some examples on this forum of fridge battery life calculations based on around one amp at 12 volts.
Although they weren't suggested for this fridge/freezer, they might be taken as starting points for calculations.
I was trying to suggest sources of more realistic figures as a starting point.

For this fridge/freezer any figure under 5 amps would be mainly guesswork as there are so many variables. It's not going to be left closed the whole time like in some of the tests for power consumption.
Efficiency, insulation, how hot it is, how often it gets opened letting warm air in, how much milk margarine etc warms up before being put back in the fridge, how much warm beer gets put in it :)

It might be a good idea to do a test first on battery whilst camping with 240 power available to see if there is sufficient capacity to run the fridge/freezer.

If there isn't enough capacity then switch to 240 and recalculate for next time.
