I agree with
John & Deborah. Presuming your battery is OK.
If you that amount of sola,r the 10 X 6 = 60ah/day, and if in hot 40 degree temp the fridge will be running almost all the time if not all the time. Just one humble Engel will use around 50AH/24 hrs. It will be on at night and the sun isn't.
That alone will be nearing the borderline of what you can make/need and if you use a TV and lights then it won't ever charge up under that situation.
You will have to build in around 100% more solar than you think is needed to cover most situations.
Does your fridge have lots of cool air being supplied to the condenser grills by a fan to move the hot away?
Does your fridge have far more insulation over the case, far more than just a the common thermal jacket.?
Is it in the back of a 4wd where the temps, although 40C outside in the air is probably 50 inside the 4wd.
Some people have fridges in a box on the drawbar = absolute disaster and as hot as you can get there.
When traveling my two fridges have a doona or sleeping bags over the cases to give a good thermal buffer so the fridge can do its job.
