(ch) The inverter is equipped with the following interfaces and functions:
User interface for the monitoring and configuration of the inverter
The inverter is standard-equipped with an integrated web server, which provides a user interface for configuring and monitoring the inverter. The inverter user interface can be called up via the web browser if there is an existing WLAN or Ethernet connection to a computer, tablet PC or smartphone.
SMA Speedwire
The inverter is equipped with SMA Speedwire as standard. SMA Speedwire is a type of communication based on the Ethernet standard. This enables inverter-optimized 10 or 100 Mbit data transmission between Speedwire devices in PV systems and the user interface of the inverter.
SMA Webconnect
The inverter is equipped with a Webconnect function as standard. The Webconnect function enables direct data transmission between the inverters of a small-scale system and the Internet portal Sunny Portal without any additional communication device and for a maximum of 4 inverters per Sunny Portal system. In large-scale PV power plants with more than 4 inverters, there is the option of establishing data transmission between the inverters and the Sunny Portal web-based monitoring platform via the Sunny Home Manager or to distribute the inverters over several plants in the Sunny Portal. If there is an existing WLAN or Ethernet connection, you can directly access your Sunny Portal system via the web browser on the computer, tablet PC or smartphone.
WLAN
The inverter 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 inverter has a WPS (WiFi Protected Setup) function. The WPS function is for automatically connecting the inverter to a device in the same network as the inverter (e.g. router, computer, tablet PC or smartphone).
The integrated WLAN interface is only designed for temperatures down to -20°C.
Modbus
The inverter 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 devices is designed for industrial use and has the following tasks:
• Remote query of measured values
• Remote setting of operating parameters
• Setpoint specifications for system control
Grid Management Services
The inverter 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.
