Hi to all you very knowledgable people out there. (Grovel Grovel)
Dumb Blonde Chick here!
I'm sure I am going over ground already covered, but can't find the info I need. Perhaps someone would be kind enough to point me in the right direction.
Can I run the existing
battery power from my car to a caravan in order to be able to have the caravan fridge running whilst travelling from point A to B - through an Inverter of course (I'm not that dumb :))
I have already purchased a 800W Modified Sine Wave Inverter (but can return if unsuitable)
How does one go about this transformation, if possible.
Thanks
Selena

Hi Selena
Before you set fire to your Vehicle and Caravan, get your local
Auto Electrician, to wire in a Anderson Plug, and
check your caravan
wiring, you might have a problem with Insurance if the lot goes up.
some Technical minded people can do it some cant.
Cheers

Our van has a three way Frig (I thought all vans did?) Anyway, when having our tow bar etc fitted to the vehicle, the Auto electrician simply wired through the flat plug connection that connects clearance lights, blinkers etc. I think it is commonly caller a "hot" wire? Anyway it works.
We had him set it up so as when the vehicle ignition is switched off it cuts the power to the Frig. Apparently Fridges will flatten your vehicle battery very quickly if the frig is left running while you are parked. Hope that helps. Cheers.

Selena,
If your caravan fridge is a three-way absortion unit, they can draw a fair amount of current and if your wiring is not up to the job you may not actually be getting 12 Volts at the fridge terminals. This is the reason people are suggesting you have an auto electrician upgrade you wiring.
Sometimes it is not practical to use the 50A Anderson plug. A possible alternative is to change to a 12 pin flat connetctor and use the 30 A pins. This connector has auxiliary terminals which can take heavier guge wire.
If you are wiring the caravan fridge from the cars cranking battery you should perhaps think about having an auto electrician install a solenoid operated from the ignition switch or a "smart" separator installed so that the you isolate the fridge from car battery when the car's engine is not running. Pain in the proverbial if you go sight seeing for a couple of hours and when you return you don't have enough charge in the battery to start the car.
Regards,
Rosscoe
