I found a bunch of cheap ones but they are only 3 amps. I need to find one that is say 15 amps (10 minimum), that takes 16.5v as it's input, up to 23V (my Voc) and will put out say an adjustable 10.5-15.0 or more volts. Ideally it is modifiable to adjust the input voltage as well as the output voltage since stock the usually only let you control the output set point.

You can add an
Emitter follower to that DC-DC convertor; it amplifies the current.
V-s is the solar panels ...
V-in is the output from the DC-DC converter ...
V-out goes to the battery.
You can put a few of these in parallel with a 1 Ohm resistor in the Base lead on each transistor.
You will need a large heat sink.
