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 ...

I would not know what is what on the circuit board.
My observation on the demo was that the PWM amps they use just happen to be the same as what the panel Isc was at the time, at different amounts at different times. Sometimes Isc is above rated. I did note that when the 230w was above its Isc, so was the 130, which means it is an insolation thing at the time, not something the controller was doing.
Jim may be onto something about what happens after Bulk and you still get more than Isc (where Isc is not over its rating at the time). Can you still do the "buck" and just not do any power point tracking?
Other MPPT controllers also drop out of MPPT and go PWM after Bulk. Do they get higher than panel Isc too after dropping out of MPPT?
