6.2.2 Active Factor cosφ(P)
Once user enables this method, inverter will deliver reactive current according to
output active power at that moment. The below figure is an example. Please refer
to 7.2.6.4.4 cosφ(P) for the settings procedure.

6.2.3 Fixed Reactive Power
Enables this method, inverter will deliver reactive power (ie. Q) according to the
fixed reactive power setting. The setting range is from Cap 53% to Ind 53%.
6.2.4 Reactive Power / Voltage Characteristic Q(U)
After selecting “Q(U) control”, User can adjust Q vs. Grid voltage operation
curves as below. The left curve is “Curve A”, the right curve is “Curve B”.
