Is anyone using solar panels to power the boat when not in use? I would like to keep my fridge running 24/7. I currently have 2 start batteries and 1 house battery setup. The house battery lasts about 5 days before the fridge knocks it down. The fridge I have draws an average of 265 watts/24hours according to the manufacturer.
I have a 30 watt/hour panel (actually two 15 watt panels in parallel) which I'm going to connect to the house battery through a battery tender. The tender kicks in @ 13v and off @ 14.2v. I, conservatively, figured 9 hours of sunlight/day which equals 270 watts. Forgiving any losses this should run the fridge continuously. If my numbers are correct, it should be enough to charge the battery and run the fridge during sunlight hours and let the fridge run off the battery at night.
Is my thinking correct?
