Stop EMI / RFI Interference in Off Grid Solar PV Systems

I also tried adding a 0.1 Uf capacitor to the other terminals on the charge controller but the only one that was effective is the one on the negative terminal of the solar panel input. As they say, your mileage may vary so its worth a try adding a capacitor on the other terminals as well. Like I stated earlier, using the AM/FM radio to see the additional capacitors will make a difference for you is a great tool.

In conclusion, I am pleased with the results of eliminating EMI from my solar PV system. My ham radio station has no RFI interference on 80 through 10 meters. I also have no interference on 2 meters.
