Pairing up the Eco-worthy 20a MPPT controller
Thanks to BFL confirming that the Eco-Worthy controller plays well when run with another controller, I felt pretty good about combining my two matched controllers. Each had one of the Bosch 245w mono ...

So I've been reading. Don't be afraid, I am enough for both of us. ;)
A buck converter is a DC to AC to DC converter. MPPT samples the array and the battery and tells the converter what the maximum output should be or tunes the system for best results.
So unless the Eco-w is shutting down the buck converter and switching to a second PWM system, the buck converter is still taking taking in higher volts at low amps and putting out lower volts with higher amps. It is just not tuned any longer because the charging is already tapered and max result are not needed.
To go any deeper requires formulas and other headache causing info.
