20A in the controller name. Does it represent capability for max AMPs coming from the PV(s), or max amps charging battery?

The 20 in 100/20 refers to the battery charging current.

That particular MPPT can also accept up to 20A solar short circuit current.

You haven’t stated what battery voltage and type also can make a difference as the 100/20 can be used on 48v systems, in which case over 1000w of panels could be connected.

I'm running quad 320w on mine with a 2 in series, 2 in parallel configuration. And I actually have two sets of that with two controllers.
