Advice on solar panels
Here's the situation. I have a Catalina 34 with the basic Adler-Balbour refrigeration unit in my ice box. I believe my unit pulls about 3 amps when the compressor is running.
My house batteries consist of 4 x 6v batteries, each one putting out approx 230 amp hours.
I want to leave my icebox running Sunday night when I leave the boat and have it still on when I get back on Friday. Boat is unplugged so no battery charger is working.
I don't mind if my batteries run down some by the time I get back on Friday, but of course I don't want them dead either.
How big of a panel do I need to keep my batteries not necessarily fully charged, but still with a decent charge when I get back and turn on the charger?
When we get to the boat, it takes a good 24 hours for the icebox to get to a good temp. And then, 24 hours later, I'm heading home.
