Ok, so my suggestion is simple, connect those 3 panels in Series, not parallel.I believe the voc is 22.3v unless I’m looking at the wrong panels on the renogy website. And the controller is an epever tracer bn with mt50. I had an epever tracer an model a month ago when this started happening.
The solar controller can handle the voltage and you will reach a voltage sooner to get it to start outputting.
