With the several series parallel type mppt setups I've looked at they all had output current drops more significant on the non shaded string than you would expect if you shaded out one leg.
I meant 24V panels all parallel with MPPT. Lower current, less resistance losses than with 12V, lower cost per panel wattage, higher cost for MPPT. The result is more output amps, though hot weather would TAD negate this.
Top-end MPPT have better algorithm, more programmability than PWM, and higher amps.
Bogart PWM is the only exception, it's hooked up to "brains" of the Tri. The Tri will control the controller, so to speak, adjusting it on the go, and clipping excessive amps up to 45A input, so you can use more panel wattage in shoulder sun. But peak amps are still 30.
