[RE-wrenches] RFI from MPPT Charge Controllers

[Larry Crutcher]

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,
