Delta RPI-H3

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.
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%.
