Gooday, I have been told that it is better to run my Engel 60 litre fridge via a power inverter so that 240 volts is achieved. I have read Robin Miller's thread 39850 and whilst informative I am rather mentally challenged when it comes to the electrical side. Thanks

Kind regards

Mike R

No, mate you are fine...Who ever told you to use an inverter is the "mentally challenged" one.

Your Engel is designed to run on 12 volt DC or 240 volt AC...Running it directly from a battery is fine...That is what it is designed to do.

Herbal Thanks will continue to run 12 volt.

Herbal is right, If you run it through a inverter it will probably flatten your battery twice as quick.

AS Herbal said, the person who told you doesn't know how an Engel fridge works. Not sure if mentally deficient but info/concept deficient.

Any 240v AC fed to it is reduced to around 12v DC so it's own internal converter can produce around 22v alternating power for the compressor.

I use that 22v to run additional computer fans inside the case to shorten run time and aid cooling efficiency.

Hi Ross,

Can you confirm the source power for the extra fan, is it 12v DC or 22v AC ? As I hadn't heard of a 22v fan before. Certainly 12 v fans, they are cheap and plentiful.

Herbal, mate remember the design of the Engel is a portable fridge that can also run on 240, not a household static fridge that can go off road.
Run it and love it on 12 volt, there is only one way you can go wrong on 12 volt, trying to run it on crappy small wiring and/or cheap connectors. Give it a healthy power feed and it will be very happy. Voltage drop at the fridge is not your friend.

Yarda, mate I did not say it was a household static fridge...

What I did say in part was - Running it directly from a battery is fine...That is what it is designed to do - ;)

Sorry Herbal, a brain fart on my part. My comment was meant to be for Mike. Sorry again for the confusion.

Hi Mike

We have two Engels and always run them on 12 volt, and often use one as our freezer.

Last trip up the Hay river track the 12v. side of our 39lt. engel went kaput at Birdsville.
The 240v. was ok.
I zip tied my small inverter from Jaycar to fridge handle running the fridge on 240v. and it kept everything cold for the next month and a half.
Also have an extra fan in the cabinet for faster cycling

As well as introducing another loss and reducing efficiency, by runnijg your fridge on 240volt inverter you have just introduced an unprotected source of 240v supply into a moving vehicle...that is not at all clever.

remember the engel already has a purpose designed inverter to run the 22 volt motor from the 12 volts.

cheers
