Isn't the solid state units attempting to maintain a consistent 6v? Doesn't that defeat the purpose of a voltmeter? You are wanting to see the variations in voltage, not look at a meter showing you a constant reading as the voltage varies. Once the voltage dropped below some level it would not be able to correct for it, but what you end up with is an idiot light, on or off.
