Procedure:
1. Ensure that the Sunny Central is in the operating state "Stop".
2. Log into the user interface.
3. Change the parameter Q-VarMod (see Section 6.2, page 40).
4. Change any parameters associated with the selected mode.
5. Use the parameter PwrMonErrMod to select the desired inverter behavior in the absence of setpoint specifications
as follows:
6. If SubVal has been selected, enter the proxy values for normal feed-in operation and for operation outside of normal
feed-in operation, as follows:
7. In the parameter PwrMonErrTm configure the time lapse until recognition of the absence of setpoint specifications.
8. Confirm the parameter entry with [Save].
8.2.1.2 No Reactive Power Control: Off Mode
The reactive power setpoint is limited to 0 kVAr. This setpoint cannot be controlled.
PFCnstAnIn The reactive power setpoint is imported via the analog input for setpoint specification. The analog
value is converted into a displacement power factor cos φ.
PFCtlW The displacement power factor cos φ is set as a function of the feed-in power. The dependency is
depicted by a configurable characteristic curve.
VArCtlVol The reactive power is set as a function of the line voltage.
VArCtlVolHystDb The provision of reactive power helps perform voltage-stabilizing measures in the event of
overvoltage or undervoltage. The parameterization is carried out by means of a reactive
power/voltage characteristic curve.
VArCtlVolHysDbA The provision of reactive power helps perform voltage-stabilizing measures in the event of
overvoltage or undervoltage. The parameterization is carried out by means of a reactive
power/voltage characteristic curve and an activation power.
Parameter block
The parameter Q-VARMod can only be changed in the operating state "Stop". The entry will not be accepted in
any other operating state.
Setting Description
LastVal If specified via communication: utilization of the last value received. In case of analog
setpoints: utilization of the last valid mean value.
SubVal Utilization of the configured proxy values. SMA recommends use of the proxy values when
setpoint specifications are effected via analog signals.
Parameters Description
Q-VArSubValRun Proxy value for the reactive power setpoint in feed-in operation
PF-PFSubValRun Proxy value for the displacement power factor in feed-in operation
PF-PFExtSubValR Proxy value for the excitation of the displacement power factor in feed-in operation
Q-VArSubVal Proxy value for the reactive power setpoint outside of feed-in operation
PF-PFSubVal Proxy value for the displacement power factor outside of feed-in operation
PF-PFExtSubVal Proxy value for the excitation of the displacement power factor outside of feed-in operation
