Added a bridge rectifier to isolate the components and prevent feedback. Once fully tested will update. still working ok ### ⭐ No stars *by C***B on Reviewed in the United Kingdom on 30 October 2018* After finally wiring this up, I was very angry to find the the charge controller was defectiveIt’s not showing me the amp going in from the solar panels.
