2.1 Appropriate Usage
The Sunny Central Communication Controller (SC-COM) is the central communication interface of the Sunny Central.
The SC-COM establishes the connection between the Sunny Central and the operator.
The SC-COM is used in the Sunny Central of the CP XT and the CP-US production series.
The SC-COM may only be used in accordance with the specifications of this manual. Any other use may result in personal
injury or property damage.
The data collected by the SC-COM can deviate from the data of the energy meter. The SC-COM data must not be used
for billing purposes.
The enclosed documentation is an integral part of the product.
• Read and follow the documentation to ensure proper and optimum use of the SC-COM.
• Keep the documentation in a convenient place for future reference.
2.2 Target Group Qualifications
The tasks described in this manual may be performed by qualified persons only. Skilled persons must have the following
qualifications:
• Knowledge of how the device works and is operated
• Knowledge of how to deal with the dangers and risks associated with installing and using electrical devices
• Training in the installation and commissioning of electrical devices
• Training in the installation and configuration of IT systems
• Knowledge of all applicable standards and directives
• Knowledge of and adherence to this manual and all safety precautions
Skilled persons must be authorised to modify grid-relevant parameters of connected devices.
The SC-COM distinguishes between two user groups: user and installer (see Section10.1, page40).
2.3 Safety Precautions
Damage to electronic components due to electrostatic discharge
Electrostatic discharge can damage or destroy electronic components.
• Observe the ESD safety regulations when working on the device.
• Wear suitable personal protective equipment for all work on the inverter.
• Discharge the electrostatic charge by touching uncoated, earthed enclosure parts (e.g. at the PE connection on the
doors). Only then is it safe to touch any electronic components.

Operating Manual SC-COM-BE-en-20 9
3 Product Description SMA Solar Technology AG
The SC-COM is equipped with serial interfaces to ensure the availability of these functions. These include, for example:
• Three LAN interfaces
• RS485 interface for communication with devices used for string-current monitoring
• Interfaces for the communication with internal inverter components
These SC-COM interfaces are wired during production. When installing the Sunny Central, connect the external data
cables to the customer connection terminals in the Sunny Central.
3.2 Network Concept
In order to transmit the data faster and more efficiently, the SC-COM is equipped with two additional LAN interfaces.
This enables two separate networks to be created as required. Due to the two separate networks, a faster rate of data
communication with extremely short response times is achieved. If your network has sufficient data transmission speed,
one network may be sufficient for both types of data.

SMA Solar Technology AG 3 Product Description
Control Network LAN2
In the control network, the specifications of the network operator for grid management, such as target values for active
and reactive power, are transmitted. The SC-COM transmits these specifications to the Sunny Central.
Monitoring Network LAN3
In the monitoring network, the data for monitoring and parameterisation is transmitted. The parameters can be configured
via an integrated web server and the user interface. The user interface also displays error messages and operating data.

3.4.2 Structural View and Device View
In the structural view and the device view, you can call up data of the individual devices of your PV plant. Depending on
the view, the devices are sorted and displayed differently.
Structural View
In the structural view, the user interface shows the devices in the order
in which they are connected to the data bus.
Device View
In the device view, th e user interface shows all devices sorted by device
type. Device types are, for example, all Sunny Centrals. The number
shown in parentheses indicates the number of devices of a device type.

3.5 Type Label and Firmware Version
The type label provides a unique identification of the SC-COM. The type label can be found on the top of the enclosure.
You will find the following information on the type label:
•Device type
•Serial number
•Registration ID
• MAC addresses of the LAN interfaces
The firmware version can be found in the user interface of the SC-COM. The current firmware version is displayed on the
right-hand side of the status bar.
You will require the information on the type label to use the product safely and when seeking customer support from the
SMA Service Line. The type label must be permanently attached to the product.
