4 Product Description
4.1 Speedwire/Webconnect Data Module
The Speedwire/Webconnect data module is a Speedwire communication interface with Webconnect
function for inverters.
Speedwire is a cable-based type of communication based on the Ethernet standard and the
communication protocol SMA Data2+. This enables inverter-optimized 10/100 Mbit data
transmission between Speedwire devices in PV systems. The Webconnect function enables direct data
transmission between the inverters of a small-scale PV system and the Internet portal Sunny Portal
without any additional communication device and for a maximum of four inverters per Sunny Portal
system. For this, a Speedwire/Webconnect data module must be installed in each of the inverters.
You can access your Sunny Portal system from any computer with an Internet connection.
The Speedwire/Webconnect data module performs the following tasks:
• Set-up of a Speedwire network in small-scale and large-scale PV power plants
• Data exchange with Sunny Portal:
– In small-scale PV systems via a router with Internet connection
– In large-scale PV power plants via the Cluster Controller
• Data exchange with Sunny Explorer from version 1.06
• For PV systems in Italy: Connection to or disconnection from the utility grid and definition of the
frequency limits to be used with IEC61850-GOOSE messages
• The Modbus interface* of the Speedwire/Webconnect data module is designed for industrial
use and has the following tasks:
– Remote query of measured values
– Remote setting of parameters
– Setpoint specifications for system control
The Speedwire/Webconnect data module is available as a retrofit kit or is pre-installed in the inverter.
