Please advise power requirements and usage

Just have a read through the replies in this post http://thegreynomads.activeboard.com/t63238648/240-volt-fridge/ which has also been discussed very recently. Sorry, but if you read through it you should come to the conclusion that you're simply wasting your time and money trying to do want you want, it just won't work effectively.

Hiya Shadow
I run a Hisense pigeon pair fridge & freezer, each about 3/4 size normal fridges.
Your question did not consider ambient temperature and it is a critical consideration.
My pair run around 180A/h per 24h at around 32 degree ambient and around 50A/h per 24h if under 20 degree ambient.
So basically you can halve that figure and apply it your load for a single fridge.

Real kindergarten terms you will be OK with your setup but watch your SOC on Day 2.......

As madaboutled mentions we did this just a few days ago - always worth reading other posts and/or doing a search first.

Interesting. I have a 12V 60lt fridge/freezer - two separate compartments - which I run at +2C and -12C.

With an ambient of around 20C it uses about 28Ah and with an ambient of 33C it uses 50Ah per 24 hours.

For many years I ran gas fridges and they do have an advantage when camped in one location for a while but having had the above fridge for 18 months I would not go back to a 3-way.

Having said that; 12V fridges do take a significant chunk of energy each day and that will often need a generator to replace - especially in Vic and Tas. The worst production I have seen from my 180W of solar panels over a full day was 2Ah (yes, two).

Thanks everyone, I think I need to clear my head and start calculationing again, I have another question. If I go with a proper RV Compressor Fridge do I have to have it vented outside my Camper Van the reason I ask is my Van is only a Mazda pop top Van like couriers use and the best location for the fridge is with its back facing towards the back of the front seats, is this okay or does the old Air have to go outside and if so would it be the same for household 240 volt fridge

Shadow, the only time you have to vent a fridge to the outside air is the operation involves the combustion of gas or a liquid fuel. Or in a word - NO.

Just make sure that you have enough air circulating around the rear to cool the compressor unit. It's surprising how many install compressor fridges in a cabinet and don't vent the rear properly.
