Charge controller Question
Hello to all. I have a question about my controllers. I have been running 9 110 watt panels with a new Midnight Classic 150. The panels are hooked up in parallel and on a good summer day create about 4.5 KW. currently I am doing about 2.7 KW a day. I have been using 4 12 volt 425 AH batteries at 24V. I just added 6 285 panels with 3 panels hooked in series. and at the end of today I only created 1.7 KW. So the question is why? I am also running a Midnight Classic 150 on the second set of panels.
