Short-circuit withstand
strength (IEC 60439-1)
Maximum allowable prospective short-circuit current:
50 kA or 65 kA (only with F296 in the 600 V model).
When you use temporary grounding (connect two sets of grounding cables to
the connecting knobs of the AC and DC busbars and PE of the inverter): The
maximum permitted prospective short-circuit current decreases to 45 kA /
1 s. To maintain the 65 kA rating, the fault current duration must be limited to
0.5 s. If the connected grounding cables and clamps are not equivalent to the
prospective short-circuit rating of the inverter, the total rating will be lower.
Frequency 45 to 65 Hz withstand with nominal dimensioning (grid-compliance may
require disconnection at stricter values).
Imbalance The inverter does not cause imbalance.
Voltage dips Max. 0% Refer to the Firmware manual.

The graph illustrates inverter operation at the nominal AC voltage and
nominal ambient (50 °C) temperature. At 35 °C, up to 110% power available.
