13 Function Description
SMA Solar Technology AG
By supplying reactive power, the inverter 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.
