7.1 Description of the Parameter Functions
The following parameters can be found in the menus. Parameters marked with * may only be
changed after consultation with SMA Solar Technology. Some parameters are preset by SMA Solar
Technology and cannot be changed.
Parameters Description of function
Red.effect.pow.
P-WMod
This parameter is used to select the procedure for limiting active power.
P-W This parameter is used to manually preset the active power limit in kW.
P-WNom This parameter is used to manually preset the active power limit in percent.
Pac nominal Nominal active power of the Sunny Central.
Pac max * This parameter is used to restrict the active power. This is necessary, for
example, if the feed-in power has to be limited at the grid node.
Smax Maximum permissible apparent feed-in power
Outp.react.pow. (Parameters in this menu are displayed but not supported)
Grid decoupling / Grid voltage
VRtg
This parameter specifies the nominal line voltage of the public grid. All voltage
data given as a percentage refers to this nominal voltage (100 % = VRtg).
VCtlhLim Threshold value for triggering at overvoltage in Level 1.
VCtlhLimTm Triggering time for the threshold value at overvoltage in Level 1.
VCtlhhLim Threshold value for triggering at overvoltage in Level 2.
VCtlhhLimTm Triggering time for the threshold value at overvoltage in Level 2.
VCtllLim Threshold value for triggering at undervoltage in Level 1.
VCtllLimTm Triggering time for the threshold value at undervoltage in Level 1.
VCtlllLim Threshold value for triggering at undervoltage in Level 2.
VCtlllLimTm Triggering time for the threshold value at undervoltage in Level 2.
VCtlMin Minimum threshold value at undervoltage in Level 3.
VCtlMinTm Triggering time for minimum threshold value at undervoltage in Level 3.
Grid decoupling / Grid frequency
HzRtg
Nominal frequency of the energy supply grid
HzCtlhhLim Threshold value for triggering at overfrequency in Level 2.
HzCtlhhLimTm Triggering time for the threshold value at overfrequency in Level 2.
HzCtlhLim Threshold value for triggering at overfrequency in Level 1.
HzCtlhLimTm Triggering time for the threshold value at overfrequency in Level 1.
HzCtllLim Threshold value for triggering at underfrequency in Level 1.
HzCtllLimTm Triggering time for the threshold value at underfrequency in Level 1.
HzCtlllLim Threshold value for triggering at underfrequency in Level 2.
HzCtlllLimTm Triggering time for the threshold value at underfrequency in Level 2.
HzCtlMin Minimum threshold value for triggering at underfrequency in Level 3.
