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 ...

CA T, thanks. If Vbatt was say 12.2, at what panel voltage would charging begin?
The long answer is I don't really know. As I recall the bats were fully charged but I drug down the voltage with house loads as I was interested in panel and controller outputs and what to expect. Only a few days before was the solar install completed so I had my Christmas toy to play with. :B
So, your 24v panel only had to be at 12.7v to initiate charging? Or am I misinterpreting that?
