The "Max. input current" is the maximal theoretical value for operation with full power when the feed-in power
is low. The device is limited to the maximum AC power.
The "max. short-circuit current (ISC
of the connected PV generator. This is the relevant value for string design and represents the absolute maximum
limit for inverter protection. The connected PV generator must be designed in such a way that the maximum
short-circuit current is less than or equal to the ISC
fore complies with IEC 61730 Class A. Under no circumstances may the design lead to a short-circuit current
greater than the ISC
