Reactive power control, reactive power standard curve cos φ = f(P)
•
For VDE ARN 4105, the curve cos φ = f(P) should refer to curve A. The set default
value is shown in curve A.
For TOR, the curve cos φ = f(P) should be curve B. The set default value is shown
in curve B.
For CEI 0-21, the default value of PFLockInPoint is 1.05. When Vac> 1.05Vn,
Pac> 0.2 Pn, curve cos φ = f(P) corresponds to curve C.
*) If the grid-connected power of the inverter ≤4.6kW, the Power Factor is 0.95 at
1.0 power; if the grid-connected power of the inverter > 4.6kW, the Power Factor
is 0.90 at 1.0 power.
