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 ...

Remember the controller uses PWM to charge with all of the time. The buck converter is always taking whatever the panel provides and turning it into a wash that the controller decides what to create and feeds that to the PWM. I believe it does this by adjusting the voltage of the output of the bulk converter to what the battery needs and the amps available at that voltage is what you get.
In absorb and float the controller is holding a voltage and there is no need for MPPT. That doesn't mean the bulk converter is going off line or I wouldn't see 45a out of my three panels in series running at 102 Voc with an array current of 10a. It's nice knowing my batteries are still being charged while I run the air conditioner.
