    Default MorningStar MPPT 60A max pv watts at 24V

    Hi there i now have 6x 220w ( 1320w) connected to a MS MPPT60 running at 24v so the limit announced is 1600W.
    I want to add another 2 panels so i will have a total of 1760W, even if this is a bit upper than the max allowed what will be the behavior will it blow up or not ?
    i expect that in peak will not use more than the 1600w but that additional 160w will not damage the controller ?

    in morningstar grid calculator this setup appear as valid, any one using a mppt60 with more pv watts than the max capacity ?




    i have send an email to Mstar but no answer...
    Regards

    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.
