Finally got around to buying one of those Waeco compressor fridges, (CFX65 litre)
Also brought a 130 watt solar panel and a 120 amp hour battery,
Hoping to make it the six days but has anyone had any experience with
using these things and how many days should I expect before I'm off to the shop to buy ice,,,

check how much your panel produces,and how much your fridge draws.

Waffles is not waffling. On this occasion at least!

In my experience that should be fine.

If your fridge should drain your battery below a certain level it could I believe shorten the life of the battery. This is to be avoided.
A charge controller will monitor the battery level, regulate charge going into the battery (I think) and cut power to the fridge at a certain point if the level of charge in the battery gets too low.
Your panel may have a controller thing on the back to send a constant level of charge to the battery.

The idea is to keep the battery as charged as possible, as they drop off fairly quickly when drained and take a lot to get them back up again. This is assuming you've got a deep cycle and not a motorbike battery you bought from a bloke you met at the pub. I'd think you'd be fine without the controller but definitely worth considering for the future.

The controller would be a fraction of the cost of what you've already invested and well worth it. It can also tell you how much power you're using, how much the panel is putting in etc etc and a whole load of other crap you probably wont care about. It does not indicate when the non alcoholic beverages are sufficiently cooled, you'll be on your own with that one I'm afraid.

I would think you should be fine. I've got a compressor fridge (upright so less efficient than the chest style I assume you have), one panel (either 80 or 120w) & I believe 200 amp hours of batteries.

I run the fridge, lights (a little), charge a mobile. Last year I was fine for the six days with the panel pretty much keeping the battery topped up as well as power consumption at the end of the week.

A guy nearby me had 1 small panel and an engel which was very cold.

I'd make sure the fridge was cold and stocked before you leave, they operate more efficiently when full as it doesn't have to use power cooling the air inside. I use an ice box as well, but that is the manner of my rolling.

Rest easy. Remember to point the panel towards our earth's 'sun' and you'll be camping like a king.

Remember its always best to camp under the shade of a big tree, a hot van will really cause your food to spoil, and use Queensland Licence plates as this would avoid the extra hours of sun from the Daylight Saving States

Thanks for the great advice youngbill,,,
Will look into getting a charge controller,
The battery we are planing to get will be expensive (AGM 120)
So its not worth breaking it (and I'm very good at breaking things)

I also have Queensland Plates so that should give us an extra hour
Thanx greybeard

Shirley. Check with someone other than me about the controller plus maybe a charger to complicate things further.

Greybeard your participation has been noted. Well done!
