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

I often wake to 12.4 or 12.5v and even tracking the sun the controllers don't ramp up to peak amps without the coffee pot pulling down the voltage temporarily. Once that has happened they will stay at peak until absorb is hit.
So at 12.5v my MPPT system is wont go peak and at a voltage low enough to get it to do so the PWM is really at a disadvantage via losing watts.
For each of us different conditions exist. Gear, expected temps, altitude and weather all play a part in what we choose. Formulas and theory don't always that those things into consideration. Only side by side testing in a unique situation will give a person the answer to what is best in their situation. Even that is hard to set up fairly.
