I recently got myself a CMG-2430 PWM charge controller(pretty cheap I know) and a 12v deep cycle battery. The problem is that the charge controller doesn't charge the battery when I connect the solar panel. ....I know that is a cheap solar charge controller but I really what to ask you guys about opinion because I might just have missed something simple. Here are all the informations about the solar panel, charge controller and battery and after that I will give some more info about the problem.
Solar panel Pmax: 20.0 W Ipmax: 1.20 A Vpmax: 16.9 V Isc: 1.24 A Voc: 21.5 V
Battery Voltage: 12 V Capacity: 20 Ah Initial current: less than 5 A
Solar Charge Controller (CMG-2430) Voltage: 12V/24V automatic Current: 30
Now, when there is no sun (or the solar panel is disconnected) it show's the moon symbol and when I connect the solar panel it does change to the sun symbol but shows 0.00 A even in full sun, and when I check the current on the battery it does confirm that is not charging. Maybe you guys have an idea of what could possibly be wrong.
I did find the problem....I finally opened the controller and guess what. ...it has a black spot and a burned moosfet near the solar input. ....thanks everyone anyway!
