Re: MorningStar MPPT 60A max pv watts at 24V
As long as you do not exceed the maximum input voltage--The MPPT charge controller will simply limit (or "clip") the output current to the maximum current rating of the charge controller on a cool / clear day when the sun is near noon. MPPT controllers, by their design, have the inherent ability to safely control/limit there output current (and voltage).
PWM controllers cannot directly control/limit their output current.
So, don't worry.
20x BP 4175B panels (replacement) + Xantrex GT 3.3 inverter for 3kW Grid Tied system + Honda eu2000i Inverter/Generator for emergency backup.
