Fixed Power Factor Cosφ(Vde-Ar-N 4105,Cei 0-21); Cosφ(P) (Vde-Ar-N 4105,Cei 0-21); Fixed Reactive Power In Var(Cei 0-21) - Delta RPI-H3 Owner's Manual

target value variably adjustable by remote control (or other control
technologies) will be specified by the network operator in the transfer station.
The setting value is either
1. fixed power factor cosφ (VDE-AR-N 4105 ,CEI 0-21)
2. displacement factor/active power characteristic curve cosφ(p)
(VDE-AR-N 4105 ,CEI 0-21)
3. fixed reactive power in Var.(CEI 0-21)
4. reactive power/voltage characteristic Q(U). (CEI 0-21)
6.2.1 Fixed Power Factor cosφ (VDE-AR-N 4105,CEI 0-21)
Users can set power factor from Cap 0.8 to Ind 0.8 (inverter would stop
reactive power control if output power is below 20% rated power). \
6.2.2 cosφ(P) (VDE-AR-N 4105,CEI 0-21)
Once user enables this method, inverter will deliver reactive power according
to output active power at that moment. Figure 6-2 is an example.
Cap 0.9
Ind 0.9
6.2.3 Fixed Reactive Power In Var.(CEI 0-21)
Once user enables this method, inverter will deliver reactive power (ie. Q)
according to the fixed reactive power setting. The setting range is from Cap
48.4% to Ind 48.4%.
