6 Active/Reactive Power Control; Active Power Control; Power Vs. Voltage; Power Vs. Frequency - Delta H9E Operation And Installation Manual

6 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.

6.1 Active Power Control

6.1.1 Power vs. Voltage

According to AS/NZS 4777.2:2020:
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.
