Max input voltage/amperage for MPPT charge controller

Normally an MPPT charger is rated for the amps that it puts into the battery. The current from the panels is a concern for your wiring size. By design most MPPT chargers are "buck" type converters, bringing a higher DC volts down to a lower DC volts (to the battery). So the current from the panels will be less than the current to the battery.
