3 Product Overview SMA Solar Technology AG
3 Product Overview
3.1 System Overview
The Power Plant Controller assumes the park management function in large PV systems. The PV system can combine both
central inverters and decentralized string inverters, which are monitored and controlled by Cluster Controllers.
Figure1: Principle of signal transfer in a PV system with Power Plant Controller
In the Power Plant Controller, the setpoints for grid management services are received and compared with the values
measured at the point of interconnection. Based on this comparison, the Power Plant Controller calculates the required
output values and transmits these values to the central inverters and the Cluster Controllers or the Inverter Manager.
The Power Plant Controller can receive setpoints digitally, analog, and via Modbus protocol. The setpoints are
transmitted by the grid operator or by a higher-level SCADA system via Modbus protocol.
The measured values that the Power Plant Controller receives are measured at the point of interconnection, processed by
a network analyzer, and transmitted to the Power Plant Controller as analog values or via Modbus protocol.
Transmission of the output values from the Power Plant Controller to central inverters, Cluster Controllers and the
Inverter Manager takes place via Modbus protocol.

13.1 Structure of the System Network
Two networks can be connected to the Power Plant Controller. This means that the output values can be transmitted to
two PV system networks.
The Power Plant Controller delivers the output values for the Cluster Controllers and the output values for the
Sunny Centrals via separate LAN interfaces.
To ensure the correct transmission of the output values, the following rules must be observed:
• If Sunny Centrals and Cluster Controllers are installed in the system, we recommend that they are organized in
separate networks.
• If the Sunny Centrals and Cluster Controllers have to be operated in the same network, only one network can be
used for transmission of output values. In this case, the time interval for transmitting output values is extended to at
least the time interval determined for the Cluster Controller.
13.2 Principle of the Communication Network
The Power Plant Controller communicates with the connected devices, with the network analyzer, the grid operator, and
the SCADA system via Modbus protocol.
The Modbus protocol is a communication protocol that is based on a client-server architecture.
Figure16: Principle of the communication network of the PV system with Power Plant Controller (example)
13.3 Scaling of the Analog Measuring Channels
The Power Plant Controller can process both analog and digital measured values.
If a network analyzer is used, the measured values are scaled automatically.
Analog measured values are measured at the point of interconnection and converted by a transducer into values that the
Power Plant Controller can process. Since the transducer can deliver values for active power, reactive power, voltage or
frequency, the input values at the Power Plant Controller must be scaled. This is the only way that the
Power Plant Controller is able to convert into technical values and continue processing the measured values from the
values supplied by the transducer.
For scaling, the possible range of the converted values and the range of the measured values must be entered in the user
interface (see Section7.9 "Selecting the Signal Source and Adjusting the Scaling of Measured Values", page34).
Operating Manual PPC-BE-P7-en-13 57
13 Appendix SMA Solar Technology AG
The range between x0 and x1 refers to the converted values. This range is dependent on the measurement signal used
and on the analog input to which the converted values are supplied.
Measurement signal Analog input Measurement range of
the analog signals
Standard signal voltage Onboard ‒10 V

The range between y0 and y1 is the range into which the Power Plant Controller scales the converted values. This is
equivalent to the measurement range.
Within the measurement range is the range in which the valid measured values occur. The lower valid measured value
corresponds to yMin, the upper valid measured value corresponds to yMax
Range of the converted

x0 = ‒32,768
x1 = 32,767

x1 = 32,767
x0 = 0
x1 = 32,767
Example: Scaling of analog input values
Analog voltage signals in the range from ‒10 V to +10 V are received at the analog input. The analog-to-digital
converter of the Power Plant Controller uses this to generate a digital signal in the range of ‒8.192 to +8.192. The
measured value processing in the Power Plant Controller calculates the reactive power value from this signal, and then
limits it to the permitted range from ‒15 MVAr to +15 MVAr.
Lower value for the range of valid measured values:
yMin = ‒20 MVAr
Lower signal value supplied by the transducer:
x0 = 8.192
Lower value of the measurement range:
y0 = ‒15 MVAr
Upper value for the range of valid measured values:
yMax = +20 MVAr
Upper signal value supplied by the transducer:
x1 = 8.192
Upper value of the measurement range:
y1 = +15 MVAr

13.4 Output Value Specification Under Fault Conditions
If transmission of the setpoints under fault conditions is not possible via Modbus protocol, the Power Plant Controller uses
a substitution value or the last transmitted value. This is set for each specific system by SMA Service.
Basically, three communication errors are possible:
Error type Control of the
Power Plant Controller
The operator setpoints are not
received by the
Power Plant Controller.
Actual values from the network
analyzer are not received by the
Power Plant Controller.
Output value transmission to the
devices is disturbed
Once the error in transmitting the setpoints of the Power Plant Controller via Modbus protocol has been eliminated,
transmission of the output values calculated by the Power Plant Controller to the devices of the PV system automatically
recommences.
The output values are calculated with
the last valid setpoint or with a
substitution value.
New output values cannot be
calculated. The controller switches to
manual operation and transmits the
last valid output value or a substitution
value.
Depending on the parameterization,
the connected devices work with the
last valid output values received or
with a substitution value.
Parameterization
Parameterization is carried out at the
Power Plant Controller.
Parameterization is carried out at the
Power Plant Controller.
Parameterization is carried out at the
connected devices.
