Auxially battery with isolator and solar battery maintainer

I want to do a little rewiring on Yo Ho next spring, but I haven't really thought through what I should do. As equipped by Parker, the boat came with two Group 27 wet deep cycles, connected to a battery switch. If I put the switch on both, the Yamaha's alternator charges both batteries. The boat has a 12V refrigerator which to date I have not used. It runs off the batteries, naturally. If I turn the refrig on and follow my usual pattern of drift fishing or fishing at anchor, it will naturally draw down stored battery juice. I could switch off one of the batteries while the engine is not running, and let the refrigerator run off of the battery that is still connected...but this cuts my start-up the engine margin of safety. Typically, while drift fishing or fishing at anchor, I shut down all the electronics. I keep my portable VHF on, though, but it has its own battery. What I am thinking of doing is installing a third battery, just for the refrigerator and/or the electronics I might use while at anchor. That part is fairly simple. The problem is, I'm not sure how I want to keep that particular battery charged. I'd like the engine to juice it back up, but I don't want to tie it into the regular circuit...and I don't want to mess with a bunch of battery switches that I'll forget to turn on/off or whatever. So I've been toying with mounting a solar panel on the cabin roof, one that is hooked only to the accessory battery. But that, of course, will not be enough to rejuvenate the accessory battery if the refrigerator is running. An alternative is a small nuclear-powered reactor, but...with Saddam on the lam, my usual eBay source of fissionable materials is gone... -- Email sent to is never read. Throw out the DC reefer. Buy an efficient dorm size AC reefer, and a 1000 watt inverter. parallel a second deep cycle battery to your house battery and run the inverter off that. As far as manual battery switching goes check with West Marine and intellitec for alternatives. Happy T day, Jim Throw it out? Well, it is built into a cabinet. I suppose I could use it for dry storage. In fact, that is exactly what I am using it for. I've been using a couple of Igloo ice coolers to keep food, and I was thinking the refrig, though small, might be a better solution for some fooostuff that likes to be cold, but not keep in ice or adjacent to pooled cold water. -- Email sent to is never read. |
