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...

"-$105 buck converter with fancy readouts attached, which has way higher voltage input limit of 60v (so it can run two 12v panels in series, which the Eco-W at 42v cannot)"
What am I missing here? Two 12v panels (say 2 x 18v) would provide up to 36v, less than the E-W's 42v.
It appears to me, matching up solar panel output voltages with buck converter input voltages is not the problem... lots to choose from. The issue seems to be with finding a buck that can handle the amps output from the panel. And like with everything else, big amps cost big bucks (pun intended).
