Buck Your Solar with a Mex Gizmo?
Mex has a thread about equalizing with this sort of gizmo http://www.amazon.com/DROK-Constant-Current-Converter-Regulated/dp/B00E8D7XYG There are many of these on ebay with different specs, so t...

..My scenario is with an ordinary PWM controller, not an MPPT which already has a buck thing in it.
I want to get more amps like the MPPT still does in PWM by using its buck thing. I got the notion that all these buck things on ebay are what is in an MPPT controller, so why not just use one with the cheapo PWM and get more amps from a panel (instead of buying a second panel)?
The MPPT and PWM controller are both buck controllers, they take a higher panel voltage and reduce it to the battery voltage.
The MPPT has the ability to track and utilize the maximum power point panel output while the PWM just averages the panel voltage at the panel current related to the sun's irradiance.
