[Elecraft] OT: Battery and charger recommendations for 50 watt solar panel

What can you tell us about RF noise from the Morningstar charge 
regulators when the wiring between panels, regulator, and battery is 
very close to antennas? I'd be willing to bet it varies widely from one 
regulator family to another.

Another critical point -- current drawn from the panels and fed to the 
battery is pulsed DC, so should be viewed DC 100% modulated by DC square 
waves. ALL wiring in the charge path must be twisted pair to minimize 
radiation from it to nearby antennas.

At my place of work we have several of their MPPT and PWM controllers in service, some as much as 10 years now. I use their Prostar PWM controller on my personal standalone system with a 100 watt panel and a modest lead acid battery. In my experience their more compact Sunsaver products work well too and both are available on Amazon.
