7.2.6.4.1
Power Limit
User can set percentage of actual or rated power to limit inverter's output power.
Inverter will start the action once user set Mode as "ON". On the contrary, inverter
will stop power reduction and back to MPP Tracking once user set Mode as
"OFF".
7.2.6.4.2
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 at that time and can't increase power if frequency back to normal till this time
was up.
