4.2 Interfaces and Functions
The inverter can be equipped or retrofitted with the following interfaces and functions:
SMA Speedwire/Webconnect
The inverter is equipped with SMA Speedwire/Webconnect as standard. SMA Speedwire/
Webconnect is a type of communication based on the Ethernet standard. This enables inverter-
optimized 10/100 Mbit data transmission between Speedwire devices in PV systems and the
software Sunny Explorer. 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, data transmission to the Internet portal Sunny Portal is carried out via the
SMA Cluster Controller. You can access your Sunny Portal system from any computer with an
Internet connection.
Class 1 wiring methods are to be used for field wiring connection to the terminals of the
communication interface.
