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 ...

awesome, thanxx!
I'm just looking at the feasibility of those 'low voltage' 24v panels some have. Yes, at 12.7v, that would not get you far, but that's just a jumping off point. As insolation increases with sun rise, the process would continue. My point is, it seems likely 30+v are not required to charge a 24v bank, using pwm... 30v should suffice... and that is only when Vbatt has risen to Vabs. And with solar generally being at a low charge rate, that should not occur until well into the charge cycle.
