(1) 25 % Pn/min for initial connection and 10 % Pn/min for reconnection.
(2) Not applicable for initial connection and 10 % Pn/min for reconnection.
(3) 30 s for initial connection and 300 s for reconnection.
(4) For Italy, the over- / under- frequency protection value and time can be
controlled by the SPI function or a remote command via RS485
communication. Please refer to “11.2.6 Interface Protection System
(SPI)” for details.
3.2.4 Active Power Regulation
Over- / Under- Voltage Response
Only applicable to Italy. The power response to the grid voltage variations can
be set via the LCD, the details are described in “11.2.4 Volt-watt Response”.
Over-Frequency Response
The over-frequency response for the country Italy is described in “11.2.5
Frq-watt Response”.
The over-frequency response for the other countries is described in “11.1.4
Over-frequency Response”.
Under-Frequency Response
For the country Germany, when there is a decrease in grid frequency which
exceeds the Start value, the inverter will increase the power output linearly with
a decrease of frequency until the End value is reached.
