Exceeding the max. input current of the inverter does not pose any danger to it as long as the max. short-circuit current of the selected inverter is not exceeded. Please refer to the data sheet or the manual of the respective inverter for the max. short-circuit current.
If the max. input current is exceeded, the inverter limits the available PV module current to the value of the max. input current of the inverter.
