8.2.1.12 Measures for Voltage Support through Parameterization of Reactive Power/
Voltage Characteristic Curve: VArCtlVolHystDb Mode
By supplying reactive power, the Sunny Central performs voltage-stabilizing measures in the event of overvoltage or
undervoltage. The parameterization is carried out by means of a reactive power/voltage characteristic curve.
The characteristic curve can be flexibly configured by parameterizing the slope, a type of deadband through two voltage
points, and a hysteresis.

The SMA Service Line must be consulted prior to selecting or configuring the VArCtlVolHystDb mode.
