8.9.2.4 DNO Power Control
For some PV installations, the local grid operator (Distribu-
tion Network Operator, DNO) may require the possibility to
reduce the power output of the PV plant by remote com-
mands. In such case, a Telecontrol receiver must be in-
stalled. Refer to section 10.3.1.
8.9.2.5 Frequency dependent Power Control
The SunMaster CS can reduce its output power
autonomously if the grid frequency exceeds the nominal
value. Refer to section 10.3.2.
8.9.2.6 Reactive Power Control
The CS inverter can produce reactive power with different
control mechanisms. The reactive power control settings
can be used to change the inverter behaviour. Refer to
section 10.5.
