Review on Renogy Voyager 20A Waterproof Solar Charge Controller | 20 Amp | 12/24V Auto by Ryan Dillon

I haven't had this long enough to give a thorough review but I'd like to report that I haven't had any RFI issues so far. After some backyard testing and nearly 48 hours of ARRL field day at 80-15 meters, no radio interference was detected from the charge controller. It's FCC certified on the manufacturer's website, although it doesn't say what it's for. It is most likely Part 15 Class B as listed on some of their other products and is what you should look for in any equipment used with radios. I was concerned about the performance of the PWM charger, but it could handle heavy 100w SSB work all day. At midnight, when work stopped, there was still enough cargo left.
