How to Troubleshoot Your Charge Controller

By Renogy marketing team Apr 20th 2023
 

Learn how to troubleshoot your charge controller by checking for loose wires and observing LED light colors. Use a multimeter to compare the PV terminal voltage with the solar panel's operating voltage. If they match within a +/- 10% range, it's fine. If not, troubleshoot the panels. Check the battery terminal voltage and ensure it aligns with the float or boost voltage specified in the controller's manual. If it doesn't, seek professional assistance.
