A brief open circuit voltage of up to 1600 V
dc
(max. 15 hours a year) is admissible for the device.
Due to the brief open circuit voltage exceedance, there is no guarantee that the integrated overvoltage pro-
tection will work correctly if the ambient temperature is > 40°C.

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
max
.)" defines together with open circuit voltage (U
DCmax
) the characteristic of
the connected PV generator. This is the relevant value for string sizing and is the absolute maximal limit for in-
verter protection. The connected PV-Generator must be designed, that the max short circuit current is below
or equal to the ISC
max
of the inverter under all foreseeable conditions and therefore complies with IEC 61730
Class A. In no condition the design may result in a greater short circuit current than ISC
max
of the inverter [See
