Fixed Reactive Power; Reactive Power / Voltage Characteristic Q(U) - Delta RPI-M8 User Manual

6.2.3 Fixed Reactive Power

When this function is enabled, the inverter will send reactive power (ie. Q) in
relation to the fixed reactive power setting. The range is Cap 53% to Ind 53%.

6.2.4 Reactive Power / Voltage Characteristic Q(U)

After selecting "Q(U) control", User can adjust "Q" against the Grid voltage
operation curves shown in Figure 6-3.
