7.2.6.4.1
Power Limit
The power limit can be set by the percentage of actual/rated power. The Mode
will turn the power limiting on and off.
7.2.6.4.2
Power vs. Frequency
Please notice the gradient is different between Italy and other countries.
-
Italy BT/ MT: used to calculate the frequency of zero power. Ie. Fstop =
Fstart + Gradient * 50
-
For other countries (ex. Germany LV or MV): Gradient means the slope
of power reduction, ie/ -xx%/Hz
Recovery time is accessible only if Country is set as Italy BT or MT. This means
If the frequency is back to normal before the time runs out, the inverter has to
stay on the power at that certain period of time and it cannot increase the power.
