Description
11.20 Reconn.PowerRamp 2 Time after reconnection in which the power limit at the
inverter output increases from 0 to the nominal power
11.21 StartingPowerRamp 2 Power rise time from 0 to nominal power
11.22 ReducePowerFreq 2 Grid frequency threshold at which the inverter output
power limit is enclosed
11.23 OverFreqDroop 2 The percentage decrease in the inverter output power
limit as the grid frequency increases above the
response threshold
11.24 CosPhi 2 Specifies the output current power coefficient ( cosφ)
and type reactive power (capacitive / inductive)
generated by the inverter
