[Elecraft] Solar Controller Question

[James Bennett]

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.

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.

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.
