2.4.2 Reactive Power Regulation
The inverter is capable of operating in reactive power regulation modes for the
purpose of providing support to the grid. These various operating modes can be
enabled or disabled via the LCD menu.
y
PF
: Fixed power factor mode.
y
Qt
: Fixed reactive power mode.
y
Q(p)
: The PF of the inverter output varies in response to the output power of the
inverter.
y
Q(u)
: The reactive power output of the inverter varies in response to the grid
voltage.
2.4.3 Power Quality Response
The inverter supports two power quality response modes, which can be set via the
LCD menu.
y
Power derating for voltage variations
:
Define the response curve with four reference voltages. The power output or
input will vary in response to the voltage curve.
y
Power derating for frequency variations
:
Define the response curve with a start frequency and an end frequency. The
inverter will reduce the power output in response to an increase in grid
frequency.
