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

A MPPT controller switches to PWM mode after float for two reasons. There is no longer the loss with the battery being at a higher voltage and the battery could not accept the additional current anyways. The extra current is still there, just not being used to charge with.
Also, with the 12v's in series the Isc stays the same as with one panel but the voltage doubles. That excess voltage creates extra amps even in float IF you pull a load. Again my panels that have a Isc of 10a produce 16a out of the controller even in float.
