Waeco use on 240V at home.

shouldnt be. I run mine 24/7 at home when not away. great for storing drinks and the such. I have noticed thast the mobitronics runs warm, but havent had it fail. Make sure you check every now and then that th efridge is still running, as i had the fuse i my mobitronic blow due to a powersurge. thanfully I didnt have anything in the fridge at the time.

From my understanding (and im sure someone will be able to clarify) that as it is a compresor driven fridge, similair to a household fridge, it is better if they are run all the time to keep them cycling. I dont know the science behind it, just what Ive been told and some common sense. Its similair to a house fridge, store it away and dont run it, risks not working the same again.

I guess you need to look at the economics of what you plan. At nearly $700 for a CF25 you could buy a freezer for much, much less. At $ 139 for the MPS 50 it could become a very expensive exercise to replace one or even more. I've had a MPS 50 go south at the worst time (dropped to output of only 6volts) and you can't just duck down to the Harvey Norman and get another one.

To be honest it would be much more economical to get a second hand freezer for even a third or half the price of the Waeco.

Have considered doing the same, Possibly even getting a solar panel/battery setup sorted, runs for free, keeps the deep cycle battery charged??? I think the fridges like a regular run, and batteries don't really like slowly going flat...
