Solar Controller Question

[Ed Gray W0SD]

I have a MPPT controller and they produce a lot of radio interference.  
 From what I understand PWM also cause radio interference.  I believe
that the older "diversion" controllers are quiet.  Normally they would
waste a lot of energy but if one were running enough equipment so the
battery was being drained faster than it was being charged I assume
there would not be much energy waste.

My question is those of you who operate with a fairly good size panel
and need a solar controller what do you use that produces no radio
interference.  I am looking at what would be set up for a RV or a good
sized boat or a day or two portable operation for something like the US
Island QSO party coming up.  We would want to run 100 watts with the K3.

This would be a 12 vdc system with something in the range of 100-140
watt panel.  Probably two 6 vdc deep cycle batteries.

Look for a Genasun GV10-PB.  MPPT, dead quiet. I'm using one with a pair
of Trojan 6V flooded lead acid batteries and a couple of 60W panels. The
link below may be the best price.

Ed,

I've been using a Morningstar Prostar PS15M for several years, connected between my G.E. 72 watt solar panel and a bank of AGM batteries in the shack. The batteries run my K3, KX3, and KAT500, in addition to a 12v desk lamp. I have zero RFI from this device.

I use KI0BK's Solar controller, $40 plus shipping, controls up to 170 watt panels, has PP connectors, no RFI. Built by a ham. Note that input and output are configured differently. Well satisfied.

I don't recall the model number, but the Morningstar I encountered on a
sailboat was quite noisy.
