7 Active/Reactive Power Control
There are 2 settings for active power and 4 settings for reactive power control that can
be configured based on the requirement of the local network operator.
The parameters are set according to the requirements of the selected country.
A change to the parameter settings may result in the approval being lost.
7.1 Active Power Control
7.1.1
Power vs. Voltage
According to AS/NZS 4777.2:2015 (6.3.2):
The volt–watt response mode varies the output power of the inverter in response to the
voltage at its terminal. The inverter should have the volt–watt response mode. This mode
is enabled by default.
7.1.2
Power vs. Frequency
According to AS/NZS 4777.2:2015 (7.5.3):
When a grid frequency disturbance results in an increase in grid frequency which
exceeds 50.25 Hz, the inverter shall reduce the power output linearly with an increase
of frequency until fstop is reached, where fstop lies in the range 51–52 Hz. The default
set-point for fstop shall be 52 Hz.
