Interfaces and Functions
The inverter can be equipped or retrofitted 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
portals Sunny Portal or Sunny Places 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
