When the grid voltage or frequency
reaches the recovery value, the
corresponding error code displayed on
the LCD will be cleared and the
inverter can start operating.

10-minute over-voltage protection (for countries except
Great Britain and Netherlands):
The inverter will automatically disconnect from the grid
within 3 s when the average voltage for a 10 min period
exceeds the set-point of 10-min Over Vtg.
Set to OFF to turn off the function.

Parameter
Explanation
Vmax-recover
Recovery value for over-voltage fault. Inverter can start
operating only when the grid voltage is below this value.
Vmin-recover
Recovery value for under-voltage fault. Inverter can start
operating only when the grid voltage is above this value.
Fmax-recover
Recovery value for over-frequency fault. Inverter can start
operating only when the grid frequency is below this value.
Fmin-recover
Recovery value for under-frequency fault. Inverter can start
operating only when the grid frequency is above this value.
Power Ramp
Rate
The ramp rate of power variation.
10-min Over Vtg
Over-voltage protection value of 10-min average voltage
10.4.7 Setting Reactive Power Regulation
For the modes Qt, Q(P) and Q(U), see “11 Appendix
IV: Power Response”.
The PF ranges from 0.8 leading to 0.8 lagging.
Leading: the inverter is sourcing reactive power to the
grid
Lagging: the inverter is sinking reactive power from the
grid.
