In that case, I recommend ten Fair-Rite #31 clamp-ons sized so that 
their inner diameter fits the cable pair -- that is, both current 
carrying conductors. They should be placed at each noise source. You'll 
need to know about the system -- whether it is a single central inverter 
that's making the noise, or multiple inverters at each panel. If there 
are multiple inverters, I'm recommending ten at each inverter.
