mppt vs pwm
Hi, A nice little video comparing mppt vs pwm with the batteries in bulk mode. mppt vs pwm

I thought there was "Shunt" vs "Series" for "PWMs" where Series means doing Absorption with constant voltage and tapering amps. (like the LandStar eg)
Now it seems "PWM" came in after "Shunt" so "Shunt" is not PWM. So what do you call it to distinguish it from "MPPT"? But MPPT came in later on too. (After PWM -Series?) And once there was PWM you get PWM-Shunts that have FET switching? Gads!
Now we seem to call any controller with no buck converter in it, "PWM" and any controller with one, "MPPT" since it seems you always get the MPPT included when you get the buck converter.
So you can use the PWM Solar30 (and other 12/24 ones) with your 24v array if you also wire your 12v batts to be 24v. But you can use your MPPT 12/24 controller with 12 or 24v array and leave the batts 12v
