mppt vs pwm

And shouldn't there also be a low setpoint voltage for switching from float back into MPPT?

My MS MPPT 60 is programmable to switch out of float and back to absorption based on your programmed minutes below the float voltage. So if you use the coffee pot or microwave for enough time(adjustable) it will go back to the absorption voltage to get topped off again.

It is not really about switching from MPPT to PWM and back. The controller will do this automatic as needed to maintain the voltage settings.
