For testing purposes (FAT) feeding transformer should not be less than 20% of the unit
nominal current or following breakers or fuses.
2.1.4
System Rated Cos Phi ID120
Enter the system rated Cos Phi.
2.1.5
System Rated kVA
ID213
Enter the system rated kVA.
2.1.6
System Rated kW
kW
ID116
Set the the rated active power of the system.
2.1.7 Nominal
DC
ID1805
This value is used as a reference point for DC Voltage reference instead of Grid Nominal
Voltage.
Recommended to set to highest DC Source voltage of the system.
Based on:
Grid voltage: Grid Nominal Voltage * 1.35
Generator Voltage: Motor/Generator nominal voltage * 1.35
DC-DC Converter: Maximum battery DC voltage.
2.1.8 Parallel
AFE
ID1501
Set this to 1 if more than one unit is connected to same DC bus.
0 = Single AFE
1 = Parallel AFE
When you select parallel AFE, DC drooping is set to 3.00% and modulation is
synchronised to reduce circulating current if the drives are in a common DC bus.
