Looking to reduce the RFI from a SmartSolar MPPT 150/35. Can any one advise the switching frequency(s) generated by the device? (Amateur Radio RFI concerns - HF 1.8Mhz - 30MHz, 54MHz, etc)
Many thanks -

I had massive RFI from my MPPT 250/100, tracked it down to the PV wires from the panels. I did 20 wraps of each PV wire through one of these mix 31's which are effective from 1-300 MHz from Palomar Engineering, I did the wrap within 6" of the end where it goes into the MPPT, it was like night and day.
