Re: Realistic expectations for my house batteries
When we bought the boat ONE of the minor things the surveyor missed was the batteries were stuck in the bilge, not in a box, not secured in any way, and not even flat.
The bilge wasn’t working so I made a box under the nav table seat. It takes the 4 GC2 batteries arranged with one long and one short dimension on a side. It is not “tight” and there is a bit of a hole in the middle but it is a very compact arrangement. It’s a bit hard to describe the arrangement, but they do not lay side by side, or end to end. It’s not ideal, but it’s what I have.
My “charging arrangement” is two solar panels each with an MPPT controller, both panels charge the bank, a wind generator through charges the bank and has a divert load, the engine which goes through a charge isolator so it charges both the house and start batteries, and a Honda generator with a very old school heavy 12VDC charger, it puts out 50 amps and will get the batteries to about 15.5 V. The charger is not hooked up. When I want to use it, very infrequently, I clamp it onto the batteries and plug it into the generator. If it dies I’m out $150 (it’s not “Marine”, it’s not “smart”).
