Buck Gizmo -Volts vs Amps ? UPDATED
Update 5 Nov. (It didn't work out as hoped) I got my little gizmo, see close-up photos here http://www.ebay.com/itm/DC-DC-15A-Converter-Buck-Adjustable-4-32V-12V-to-1-2-32V-3-3V-5V-24V-Step-Down...

So, pwm is really no different than any power supply/smart charger, in that it goes thru a cc/boost stage, followed by a cv/abs stage, all determined by battery voltage and acceptance?
And, mppt operates in cv mode during boost, and remains in cv mode during abs, all determined by the amount of power available from the solar panel? And if so, then if the batts are at 12v, and the battery's 'R' requires an additional 0.2 volts to overcome R, then amperage will be 160w / 12.2v = 13.1 amps?
And seeing as the panel's power could be continually fluctuating, it would be difficult for the OP to determine the max power point. But on a 'steady weather' day, it would perhaps be within his means?
