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

It makes sense to me that pwm does basically nothing, voltage wise, while in bulk. It seems correct to suggest pwm simply sits back, while Vbatt and Rcircuit determine the voltage necessary for charging. Once the setpoint is reached, and cc changes to cv, then the pwm does its thing.
For example, if I set a converter/charger to 14.8v, and the battery is at 12.2v, the voltage will start out in the high 12 to low 13v range, not 14.8v. So it is the battery and circuit that determine the necessary voltage, not the charger. Likewise, although 17 volts may be available from the panel, they will not go into the bank during bulk stage.
