2.1 Intended Use
The Webconnect Data Module is a Webconnect communication interface for inverters based on the
SMA Speedwire technology.
Speedwire is a cable-based type of communication based on the Ethernet standard and the
communication protocol SMA Data2+. This enables inverter-optimised 100 Mbit data transmission
between Speedwire devices in PV plants.
The Webconnect function enables data transmission between the Internet portal Sunny Portal and the
inverters. Data transmission takes place via a router with Internet access. A PC with the software
Sunny Explorer* is also connected to the router.
* as of software version 1.04. Sunny Explorer is available free of charge at www.SMA-Solar.com.
The Webconnect Data Module performs the following tasks:
• Set-up of a Speedwire network
• Data exchange with the Internet portal Sunny Portal and Sunny Explorer via a router
A plant in Sunny Portal can consist of a maximum of four inverters with installed Webconnect Data
Module. The Speedwire network can be set up optionally with the following topologies:
• Linear topology
• Star topology
