Simple question, does it hurt to keep a 12v upright compressor fridge in a caravan running, whilst on the move?? Would be powered by the standalone battery on it's own of course...( Need to work out how to wire battery and charger in is all)

It is normally run off the car by a heavy wire from the aux battery to an Anderson plug at the rear and a same size wire direct to the fridge.

8 B&S would be the minimum for both + and earth.

Anything smaller results in voltage drop.

Otherwise you would need a long extension cord for the charger LOL

Simple answer........No!

You can wire it up to run from either the 'house' battery in the van or from the battery/ies in the tow vehicle or both.

Hi Kevmac

As we have solar panels to charge our van batteries, power supply is not a worry. We run our 12 v upright caravan fridge as well as an Engel set as a freezer all the time. We have an Engel in the tow vehicle which runs off a separate battery also solar powered.

When we had a small camper, we ran an upright caravan fridge from one battery in the caravan, charged by a portable solar panel when we stopped (panel that is now on the on the tow vehicle). We also had trickle charge from the tow vehicle but that put in minimal compared to the panel even late in the afternoon.

Still want some of our rain down there ???? you can have it...
I always leave the Engle running whilst on the move as it runs off the aux batterys and they will be getting charged at the same time, if i run it when i stop only it has to cool back down again and draw power whilst not being replaced by charging ....
I would have an anderson plug to the car so the car charges the van batts and then certainally run the fridge whilest car is running so it is nice and cool and will not draw as much power to "maintain" it rather than it having to bring it down to the temp you need with no charging happining ........
Cheers to cold Albany Kev,
you know i can remember visiting the whaling station when it was operating, the sight of the blood running into the water and them cutting the blubber off and most of all the smell of the boilers .... still can smell it now if you go over there eh.....
