My first reaction would have to be the old adage "You get What You Pay for"
They copied / pasted the MS manual in many places.........
Looks as if they tossed in several useless features to make it look good. An example the load function which is typically only seen on low cost low power units

Doesn't that mean the 30 amper can have more total Voc and so more panels, but they have to be smaller to not go over the watts limit?
Seems backwards to me.

Hi BFL13,
The input voltage limit does not change the output of the controller. I.e.
30 amps X 12 volts = 360 watts output, 40 amps x 12 volts = 480 watts.
Since it they are both MPPT you could feed them with up to 150 volts for the 30 amp and up to 100 volts with the 40 amp.
I.e.
150 v x 2.4 amps = 360 watts for the 30 amp
100 v x 4.8 amps = 480 watts for the 40 ampBFL13 wrote:
I got lost again how the 40amper could do more watts than the 30amper but with 100v limit where the 30 has 150. So picking panels and arranging your strings and parallels must be a tricky business. ?
