6.3.6.4.3Constantcosφ
This feature is not available for CEI 0-21 or A70.
6.3.6.4.4
cosφ(P)
This feature is available for Italy CEI 0-21 and Italy A70.
With this feature a solar inverter can regulate the power factor as a function of the actual delivered
active power.
The following graph is an example how the values could be set:

Figure 6.31.: cosφ(P) graph
There are two possible curves de ned in the cosφ(P) graph, curve A in blue (the default) and
curve B in red. Pn = nominal power
CurveA(inblueonFigure6.30)
A is identi ed from Plock-out = value from local grid operator and cosφ = 1
B is identi ed from Plock-in = value from local grid operator and cosφ = 1
C is identi ed from P = Pn and cos = cosφmax
CurveB(inredonFigure6.30)
A is identi ed from Plock-out = P = value from local grid operator and cosφ = 1
B is identi ed from Plock-in = value from local grid operator and cosφ = 1
C is identi ed from P = Pn and cos = cosφmax
