SMA SUNNY CENTRAL 900CP XT - Q at Night Depending on the Grid Voltage: Varctlvol Mode

10 Function Description
SMA Solar Technology AG
User Manual 103SCCPXT-E7-BA-en-58
The analog value is converted to a setpoint for power limitation. Here, the parameter QoDQmax is the end point of
the linear characteristic curve.

Consultation prior to parameter change
The parameters of this mode can only be selected or changed after consultation (see Section13 "Contact",
page153).
The reactive power is set as a function of the grid voltage. The reactive power setpoint is adjusted in stages.
