Interfaces and Functions
The product is equipped with the following interfaces and functions:
User interface for configuration and monitoring
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.
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 WLAN or Ethernet connection, you can directly access your visualized system via the web browser on your end device.
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.
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 of the product is only designed for temperatures down to -20°C.
- Deactivate the WLAN interface at low temperatures ( > Switching WLAN On and Off).
Modbus
The product is equipped with a Modbus interface. The Modbus interface is deactivated by default and must be configured as needed.
The Modbus interface of the supported SMA products is designed for industrial use – via SCADA systems, for example – and has the following tasks:
-
Remote query of measured values
-
Remote setting of operating parameters
-
Setpoint specifications for system control
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.
All-pole sensitive residual-current monitoring unit
The all-pole sensitive residual-current monitoring unit detects alternating and direct differential currents. In single-phase and three-phase inverters, the integrated differential current sensor detects the current difference between the neutral conductor and the line conductor(s). If the current difference increases suddenly, the inverter disconnects from the utility grid.
