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...

What's messing you up is that you're trying to fit your buck converter into the same relationship as the total function of an MPPT controller and that isn't the case. Salvo defined it above. The MPPT controller is able to control output to the battery by boosting more amps at the sake of voltage. Your buck gismo is more of a voltage source and can't vary voltage to increase amps to the battery.
That is even more mixed up than I am! :) Oh well, it is late.
The buck converter has an adjustable voltage output (CV) which you can set for a lower voltage than its input voltage, so it makes more amps out from the same wattage.
OTOH, westend may be right! :( I will post my gizmo test in a new thread.
