Hi, A nice little video comparing mppt vs pwm with the batteries in bulk mode. mppt vs pwm

Apparently a pwm controller applies the battery voltage to the panels during float or absorb.
No. The panel's voltage is dragged down to battery voltage. . . always. At higher SOC the battery voltage is climbing, current is dropping and panel voltage will continue to climb. This is the major reason for a controller. Batteries can't tolerate voltage beyond a certain level and certainly not approaching Voc.
Right.
