SMA Solar Technology AG 4 Product Overview
The function of the Modbus server is available via the Ethernet interface (Modbus TCP). The
Modbus server can be used for external access to the product (e.g. via SCADA systems).
The function of the Modbus client is available via the Ethernet interface (Modbus TCP) and the
RS485 interface (Modbus RTU). The Modbus client can be used for communication with connected
Modbus devices (e.g. inverters, energy meters, I/O systems).
For the communication with connected Modbus devices, predefined Modbus profiles and user-
created Modbus profiles can be used. User-created Modbus profiles can be exported and
transferred to another product.
SunSpec Modbus
The product supports the standardized SunSpec Modbus profile via the interface of the Modbus
client (Modbus TCP/RTU). The SunSpec Modbus profile from the SunSpec Alliance contains a
comprehensive set of measured values and parameters for Modbus devices in decentralized power
generation systems (e.g. inverters, energy meters, weather stations). The product has data points of
the SunSpec Alliance and therefore conforms with the SunSpec Modbus profile of the underlying
specification version (see www.sunspec.org). Connected Modbus devices compatible with the
SunSpec Modbus profile are automatically integrated into the system with the appropriate Modbus
profile.
Plant-wide parameterization
You can use the system parameter assistant to change the parameters of connected devices at the
same time and to compare them. Simply select the desired devices from a list and change the
parameters that are suitable for simultaneous change. The status of the parameter changes is
accessible at all times.
Energy monitoring
Several SMA Energy Meters and Modbus energy meters from other manufacturers can be
connected for comprehensive energy monitoring. The product can also read out, save and display
the generation and consumption data of the meters.
In addition, energy meters (e.g. a gas meter) can be registered via the extended functions in
Sunny Portal. The meter readings can be entered manually and displayed.
FTP Push
The FTP Push function can be used to upload collected system data to a freely selectable external
FTP server. The collected system data is uploaded to the specified folder up to 1 time per hour per
day. Here, the system data is exported in an unchangeable XML format. The system data and user
data is transmitted via standard FTP protocol to the FTP server without encryption.
SMA Smart Connected
SMA Smart Connected is the free monitoring of the product via the SMA Sunny Portal. Thanks to
SMA Smart Connected, the operator and qualified person will be informed automatically and
proactively about product events that occur.
