I only use these types of fridge units when there is a sufficiently large solar array and battery bank in place. That means a battery of at least 300 amp/hours and the solar to charge it.
The 5 amp rating that you see listed is at 100% duty cycle. It has been the experience of many of my clients that the actual draw from a fridge powered b a Danfoss compressor is more like 40-50% of the rating, as the unit does not operate continually.
With that in mind, a 5 amp rating would turn into a 2-2.5 amp/hour draw. Over the course of 24 hours, that would be about 60 amp/hours max. Any properly designed and installed solar charging system will replace that amount of power easily, usually by early afternoon.
