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 ...

Altitude makes it unfair for me to do a direct comparison.
Panels, like generators are rated at sea level. Their caraturistics at 10,000 ft are completely different.
Thin air, low humidity, extreme light levels, cooler all temps produce higher Voc and Isc. I see over 10a Isc in Denver and higher at altitude. The difference between hot and cold for me is a half a amp, not amps.
