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

Since MPP is at the knee of the IV curve with Vmp being lower than Voc, it seems the panel voltage would go down the steep slope to the right to get the reduced power which means panel voltage is higher than Vmp during Absorption as stated by 12thgenusa above?
PWM is on/off, on near Vbatt off near Voc (no power), average of Vbatt and Voc is greater than Vbatt, as the duty cycle decreases (longer in Voc) the circuit stays open longer, longer at Voc.
