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 ...

BTW I've never understood or perhaps appreciated how a PWM controller can charge at Isc.
I've connected panel wires together to measure Isc. Great but guess what? Yup the voltage is 0V, so how does the battery get charged? Capacitance or inductive energy in the controller?
