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 ...

Interesting that the 245s get the same amps (just under 16) the 230 gets.
On the Eco-W, perhaps Jim can confirm if ever noticed, but I believe I have seen this several times now.
After you get to your high set point and Bulk ends, it drops to the Float voltage set point so it is supposedly now in PWM. Panel Isc is say 8.5a, but the controller readout might still be showing (confirmed by Trimetric) you are getting say 11 amps and are in Float.
I thought PWM meant you can't exceed panel Isc. Does that mean the Eco-W is really in MPPT during Float? This would be before battery voltage drops below 13.2 so it can return to Bulk.
