4.3 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).
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 inverter and SunnyPortal 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. You can directly access your visualized system via the web browser on your end
device.
