Setting Parameters
Changing certain parameters may prevent disconnection from the grid if the new values
exceed those given in the standards of the country of installation. If these parameters are
changed to values outside the standard range, an interface protection must be installed
external to the inverter in accordance with the requirements of the country of installation.
These parameters can only be displayed with the Aurora manager Lite
interface SW.
The table below shows the parameters that can be changed and the
range of values that may be set for each:
Parameter Description Setting range
Set U>> Grid over-voltage (OV) threshold (extended range) Unom … Unom x 1.3
Set U<<
Grid under-voltage (UV) threshold (extended range) 10V … Unom
Set F>> Grid over-frequency (OF) threshold (extended range) Fnom … Fnom + 5Hz
Set F<< Grid under-frequency (UF) threshold (extended range) Fnom - 5Hz … Fnom
Set U> Grid over-voltage (OV) threshold (restricted range) Unom … Unom x 1.3
Set U> (10Min) Over-voltage (OV) threshold (average grid voltage value) Unom … Unom x 1.3
Set U< Grid under-voltage (UV) threshold (restricted range) 10V … Unom
Set F> Grid over-frequency (OF) threshold (restricted range) Fnom … Fnom + 5Hz
Set F< Grid under-frequency (UF) threshold (restricted range) Fnom - 5Hz … Fnom
Set Uconn> Max. permissible voltage during checks prior to grid connection Unom … Unom x 1.3
Set Uconn< Min. permissible voltage during checks prior to grid connection 10V … Unom
Set Fconn> Max. permissible frequency during checks prior to grid connection Fnom … Fnom + 5Hz
