Im leaving my boat on mooring
for 2 months over Christmas/New years, and worried that the solar panels
might over- charge the batteries in the tropical sun. Wondering if I should dis-connect one or both panels
I'm using 2x 135 watt pannels on a digital 25 amp charge controller (blue sky 'solar boost 2000e), with 400 amp hours of gel batteries.
I intend to turn all systems off (except automatic bilge
pumps) and don't need much juice. The batteries are quickly full (14 volts) in the tropical sun. My worry is if the charge controller fails, I might cook my batteries, or worse...
