I have something like loud clicking noise
across most frequencies on bands from MF to VHF
. I believe it's my el-cheapo solar
charge controller. Here is why:
1. With all consumers of electricity off, it's clicking.
2. With the battery
disconnected from the controller, it's still clicking, but in a different way (slower, and with several second pauses between series).
3. With solar panels
disconnected from the controller, or at night, there is no clicking at all.
The controller in question is Renogy 30 Amp PWM, Renogy 30 Amp PWM Charge Controller - SolarSyn
Should I get a new controller (which one), try to add some chokes to the output wires, or?
By the way, "Positive Ground Controller" sounds odd, doesn't it? So far I've no idea what that's all about, but my ground is negative, like everyone else's.
