Re: Solar charge controller question
I went to the boat yesterday to install the new controller. Following the advice Mainesail gave me, I checked the amp and volt output of the panels with the old controller before I removed it. it wasn't a very sunny day and the angle was getting low, but the old controller was putting out 1.3 amps and only 12.8 volts. We put in the new controller and saw a jump to 2 amps and 13.1 volts. It looks like the old controller might have been the problem after all. I left the panels charging my 160a house battery and will return in 2 weeks to see the charge state. If all is well, I hope the see the little blinking light that indicates a full battery on float charge.
