We just got back from a two week cruise. We used 60 to 70 amps each day for everything. 80 to 85 degree weather. Lights, pumps a little TV and music. My refrig draws 4.6 amps when running.

Hi Bill;
It's hard to quantify a correct value because, as you stated, different outside temperatures, how full the fridge is, how good the seal is and how often it is opened; will affect the daily draw...
That being said, my fridge draws about 5 amps and the duty cycle can be as high as 40% an hour in hot weather,
 For what it's worth, we have a100W solar panel and in summer weather (when the sun shines bright and for longer days!) I get about 5.5 to 6 amps to the batteries.   *You will need to calculate the Ah depending on your stats)...  This allows us about 4 days at anchor before the batteries are down to where I would need to run the engine for a charge.  (We cruise the west coast of Canada and often don't see a dock for a week or two unless needing fuel).
Hope this is of some help.
 

I'd say about 5 amps after initial draw and runs approximately 40-50% of an hour on a warm to hot day here in Maine waters approximate temp about 75 degrees. So that would make it approximately 2.5 amps per hour and 60 amps in 24 hrs.

If this helps anyone. We have 240 watts of solar with a Kiss wind gen. We anchor out for 6 months of the year with only one night in a marina. Our fridge Is only turned off to defrost.

Bill. We came out of Lake Michigan 4 years ago and now boat Florida and the Bahamas for 6 months in the winter. We have 240 watts of solar and a kiss wind gen. Our fridge is only turned off to defrost. We have never had a issue with lacking for power with how I have our boat set up. We charge our laptops and run the 120 volt vac when needed.

Our refrigeration runs at about 75% duty cycle, so about 90 amp hours for a 24-hour period.  We're on a mooring and just use solar, so we need to average 10 amps of current into the system for the 9-hours of meaningful sunlight here in the Northeast during the summer.  We have two flexible solar panels on the bimini, each rated at 100 watts, and they ALMOST keep up.  Refrigeration, especially air-cooled units, are power hungry.

I would suspect that using an ambient temperature of 70 degrees that your duty cycle would be about 50%, so about 60 amp hours for a 24-hour period.  Best guess (given your latitude) that 200 watts of solar panel would be a good place to start.  You could always use matching flexible panels in 50 watt increments, use MC4 y-cables to parallel the panels, and dial-in almost your exact needs,

We have lived on the hook for 3 winters now of at least 5 months each. We have 240 watts of solar and we run a Kiss wind gen. Our fridge runs 24 /7 and is only turned off to defrost at times. We have never lacked fee power with our set up.
