Hi. I have a 30HP mariner with a dedicated cranking battery on my boat. I want to install a 12V refrigerator which pulls 40-60W and so need a deep cycle battery. The thing is how do I keep it charged? I don't have shore power and I presume my outboard won't be sufficent. What are my options?
<br /><br />Sorry, couldn't resist. I take it this is not a trailered boat? <br /><br />I agree, I wouldn't count on the outboard to keep it charged - and it would take a boatload of solar cells. Multiple batteries in a parallel connection will give you longer run time - but without a power source you're left with bringing them home with you.<br /><br />They do make dual-powered appliances - I'm not sure...maybe you could run it on propane while in the slip and battery power on the water? I'm just guessing here - I'm thinking a propane fridge could be left unattended, but not a running generator.<br /><br />good luck...
