Manual just says max 15 amp fuse
I assume this fridge draws 10/12 amps at 12v near continuous.
The minimum I see is 6 batteries and 600+ watts solar.
Plan to have a small generator to use as needed. With a generator you can get by with less battery and solar until you see what works.
This is why most use a propane fridge.
Read the yachting forums. These 40 year old fridges are thrown overboard and replaced with modern Danfoss compressor, 12V DC fridge/Freezers that are much more reliable and use 1/3 the amps. 200W solar and 2 6V GC2,s are what you would need extra for a modern 12V compressor fridge. For what the OP has, at least 3 times that amount. My 5 years experience with a similar sized 12V fridge as the OP is that 50% cycling was the max for us depending on as many as 6 factors which adds up to around 65AH/day being the highest draw/day.
