Interfaces and Functions
The inverter can be equipped or retrofitted with the following interfaces and functions:
User interface for monitoring and configuration
The product is equipped as standard with an integrated webserver, which provides a user interface for configuring and monitoring the product. The product user interface can be called up via the web browser if there is an existing connection to an end device (e.g. computer, tablet PC or smartphone).
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.
SMA Webconnect
The inverter is equipped with a Webconnect function as standard. The Webconnect function enables direct data transmission between the inverters and Internet portals Sunny Portal and Sunny Places without any additional communication device and for a maximum of 4 inverters per visualized system. In PV systems with more than 4 inverters, there is the option of establishing data transmission between the inverters and Sunny Portal via the data logger (e.g., SMA Data Manager) or distributing the inverters over several systems. If there is an existing WLAN or Ethernet connection, you can directly access your visualized system via the web browser on your end device.
WLAN
The product is equipped with a WLAN 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 an end device.
Limited function in the event of frost
The integrated WLAN interface is only designed for temperatures down to -20°C.
- Deactivate the WLAN interface at low temperatures ( > Switching WLAN On and Off).
Limited 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.
Captive Portal
The product is equipped with Captive Portal as standard. By scanning the QR Code attached to the product, access to the product is established via WLAN and the connection to the user interface is made automatically.
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-12 und SI8.0H-12.
Data Storage
Event messages and instantaneous values are saved in the Sunny Island. This data can be evaluated and thus the operating processes in the Sunny Island system can be traced. From this, for example, parameter settings can be derived that will e.g. increase the self-consumption of PV energy or the service life of the battery. For SMA Service, this data simplifies the analysis of any errors present and the identification of possible solutions.
The storage capacity of the inverter can be extended with the optional micro SD card. Thus, for example, data can be recorded over longer time periods, enabling extended diagnostics possibilities to be used ( > Data Storage Capacity).
Grid management services
The product is equipped with service functions for grid management.
Depending on the requirements of the grid operator, you can activate and configure the functions (e.g. active power limitation) via operating parameters.
