I purchased a 100 Watt WindyNation Panel kit with a P30L controller about a year ago. I was fine until I noticed today no power from the panel. Blank screen on the controller - no power into the battery. How can I troubleshoot to isolate the problem? Where to start?
A inexpensive multimeter will find the trouble spot very quickly. Set it to your system voltage and check your wiring conections. The issue could be a simple lose conection or broken wire.
The problem was that my controller was not functioning. I believe that it got wet in a rainstorm. The unit was not protected. Replaced with a new controller (now protected from elements) and my panel is working again.
