Operating the PV inverter
notes:
In the formulas on the previous page, the
parameters mentioned are named differently
as in the menu page
Curve a (in blue) Figure 6.30
Point A = Plockout = Lower Power
Point B = Plockin = Upper Power
Point C = Lower limit • cosφ
Curve A is followed when Lower Power is not
equal to Upper Power
Curve B (in red) Figure 6.30
Point A (Lower Power) = Point B (Upper
Power)
Point C = Lower limit • cosφ
Curve B is followed when Lower Power =
Upper Power

Lock-in Voltage*
230-253 V
241.5 V is default value and is 1.05Vn (Vn =
230V)
Lock-out Voltage*
207-230 V
230 V is default value (adjustable at 0.98 Vn
to Vn; Vn=230V). When the grid voltage ≤ the
Lock-out voltage
