4 Product Overview
Smart Inverter Screen
The Smart Inverter Screen enables you to view the status display and to display the nominal energy throughput and
state of charge of the battery on the user interface login page. You therefore have an overview of the most important
inverter and battery data without having to log into the user interface.
The Smart Inverter Screen is deactivated by default. The Smart Inverter Screen can be activated via the user interface
once the inverter has been commissioned.
SMA Speedwire
The product is equipped with SMA Speedwire as standard. SMA Speedwire is a type of communication based on the
Ethernet standard. SMA Speedwire is designed for a data transfer rate of 100 Mbps and enables optimum
communication between Speedwire devices within systems.
The products supports the encrypted system communication with SMA Speedwire Encrypted Communication. In order
to be able to use the Speedwire encryption in the system, all Speedwire devices, except for the SMA Energy Meter,
must support the function SMA Speedwire Encrypted Communication.
SMA Webconnect
The product is equipped with a Webconnect function as standard. The Webconnect function enables direct data
transmission between the product and Internet portals Sunny Portal and Sunny Places without any additional
communication device and for a maximum of 4 products per visualized system. In PV systems with more than 4
products, there is the option of establishing data transmission between the products and Sunny Portal via the data
logger (e.g., SMA Data Manager) or distributing the inverters over several systems. If there is an existing Wi-Fi or
Ethernet connection, you can directly access your visualized system via the web browser on your smart device (e.g.
smartphone, tablet or laptop).
WLAN connection to SMA 360° app
The product has a QR code. By scanning the QR Code attached to the product via the SMA 360° app, access to the
product is established via WLAN and the connection to the user interface is made automatically.
Wi-Fi
The product is equipped with a Wi-Fi interface as standard. The inverter is delivered with the WLAN interface activated
as standard. If you do not want to use WLAN, you can deactivate the WLAN interface.
In addition, the product has a WPS function. The WPS function is for automatically connecting the product to a
network (e.g. via router) and establish a direct connection between the product and a smart end device.
Limited radio range
The WLAN interface integrated in the inverter has a limited range of 5 m.
• Take this range into consideration when establishing the WLAN connection.
Limited function in the event of frost
The integrated WLAN interface of the product is only designed for temperatures down to -20°C.
• Deactivate the WLAN interface at low temperatures (see Section 8.9, page 114).
Multicluster Communication
In a multicluster system, the masters of the clusters must communicate with each other via a separate CAN bus. The
Multicluster data module SI‑SYSCAN.BGx must be installed in each master for this multicluster communication. The
interface slot SISYSCAN is for connecting the Multicluster data module SI‑SYSCAN.BGx.
If the Sunny Islands are ordered with the communication interface multicluster CAN, the masters are delivered with
multicluster data modules.
Multicluster communication only functions with the device types SI6.0H-13 und SI8.0H-13.
