Power vs. Frequency
Please be noticed, the definition of Gradient is different between Italy and other
countries, the explanation as below,
-
For Italy BT/ MT: It is 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 setting is Italy BT or MT, means the inverter has to
stay on the power a
t that time and can’t increase power if frequency back to normal till this time
was up.
