Hi Glenn,
Sure, except for morning net operations right when the controllers are
starting up. Or, daytime on 20 meters for DX operations. Or for weak
signal work or daytime AM radio listeners...and so on. Point is to
find an alternative to the noise.
Dan,
Thanks for the suggestions. The RF noise can be picked up over 100
feet away. #1 & #2 are standard procedure. I have not tried #3 but I
have tried ferrite material on controller in and out wires, no change.
Can you suggest a part number? #4, a Faraday cage might work if the
controller is in the RV storage area and not inside on a wall.
Anyone know about the Xantrex XW, Tristar or other MPPT controllers?

Band conditions are much more conducive to distance operating and
are much
quieter at that time.

Subject: [RE-wrenches] RFI from MPPT Charge Controllers
Does anyone know of a large MPPT controller that does not produce RFI?
Specifically, customers that are SWL, AM or amateur radio operators
need RF quiet time during the day while operating or listening. All
the controller I have installed make some noise. The Outback MX60 in
my RV decimates every 40 kHz or so with broadband noise from 160
meters and up.
Does anyone know how the Xantrex SW, Tristar MPPT or Apollo do with
RFI?
Many thanks,
