12v MPPT and 24v MPPT vs 24v PWM Test
Got a chance to try out comparing amps to the battery using MPPT vs PWM on a 24v battery bank and comparing those with the usual MPPT on 12v with my 230w panel. The bank is four 6s, so it was easy ...

Seeing as mppt use watts, it seems to me an increase in watts would be required; not an increase in voltage, necessarily?
Perhaps there are just different ways to view how the charging gets accomplished. :@
