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

Mode ON I OFF This switches the feature on and off. Default

mode is OFF.

*These values are only adjustable if Country setting is Italy CEI-021 or Italy A70. This means the

inverter will feed in reactive power depending on the active power once the grid voltage is higher

than Lock-in Voltage. When grid voltage is lower than Lock-out voltage then inverter would go

back to pure active power control.

For countries other than Italy, cos φ(P) control would not be effected by the grid voltage.
