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 ...

In the summer 0f 2013, I let the magic smoke out of my MS SS 10 PWM controller. Within a week, I had installed an MS MPPT 15.
I rewired the two 85W panels to series.
The maximum I ever observed from the PWM was a little over 9A. Almost immediately, I observed over 10A with MPPT. That is about an 11% increase.
I believe I get more daily AHs now with MPPT.

Last summer in MI saw 10.5 amps many times out of my ss-10 pwm with two 80 panels in parallel during bulk mode. Measured it with a Sears Clamp on AC/DC amp meter
I have to imagine the differences could be due to panel specs, and perhaps quality?
