60 Cell Panel vs 24v Bank MPPT and PWM UPDATE
UPDATE--results with MPPT posted 1 June. Got a chance to run this test today with no clouds but a slight haze up high so not quite 1000 insolation, showed as 8.93Isc vs rated 9.0, however that did ...

Hey, keep emotions out of it. And stop being a cry baby!
If there isn't adequate voltage headroom the controller won't output any current in mppt mode. But that doesn't mean you can't get production out of the controller. The controller switches to pwm mode.
You haven't proven the controller is operating in mppt mode. Just stating it's in boost mode doesn't cut it.BFL13 wrote:
Salvo, you are being a real PITA about this. You first said it was the Vmp that would prevent any amps, but now that you can see the controller finds higher Vmps to keep the amps coming, you are still arguing!
The results are the results! If you don't like them get your own results or get somebody else besides me to get some and see if you like those any better!
Gee whiz!
The instant it went from Bulk to Float, "panel voltage" went from 31 (near Vmp) ( as it had been steadily since being 29v) to 35 (near Voc same as with PWM). You can interpret it all you like. That's what happened.
