Solar system not fully charging battery
My battery is not at all charging completely as the controller indicates around 30% charge only. I used to get around 6 hours of good sun light at present.
I checked the current from the panels to controller, it is only delivering 3 A in total from both panels, even if I disconnect any one panel, the current remains the same.
The voltage output is around 15 V for both panels when connected to controller, I have checked by replacing my controller with another one, but it also gives the same result.
My battery is fairly new one. I got around 6 A from individual panels when checked in short circuit mode.
I can't understand why the panels are not delivering current to battery as if it seems like battery does not require it.
