I know these threads generate a lot of white noise, pun intended, but here goes.

I am planning a trip to the cape taking my 5 metre boat, the boat is going on a barge from Cairns to Seisia, I will have a 60 lt fridge in the boat and I need constant power to it.

Question 1 What is the smallest solar panel I would need to charge the battery while the fridge is running, probably in freezer mode under the deck and under a boat cover, so well shaded.

Question 2 will the outboard power keep up charge to the battery with the fridge running as a fridge, under the deck.

My outboard is a 2013 75 Honda it's alternator puts out 44 amps 554 watts and battery charging is 35 amps, does anyone know how effective this would be charging the on board battery ( generic ) and a Gel-Tech 8G31DTM it's specs are 780 MCA 550 CCA 98 AH @ 20 hours, the batteries will be separated.

My thoughts on operation, I would like to mount the solar panel above and to the bait board on the rear of the boat, this is why I would need a small panel, so when the engine is off the battery can charge, is it also possible to use the engine and the panel together once we are on the water or would I have to disconnect the panel.

I hope that's enough info thanks in advance.

Steve.
