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:
• Setup of a Speedwire network in small-scale and large-scale PV systems
• 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 software version 1.06
• The Modbus interface* of the Speedwire/Webconnect data module is designed for industrial
use and offers the following functions:
– Remote querying of measured values
– Remote setting of parameters
– Specification of setpoints for PV system control
The Speedwire/Webconnect data module is available as a retrofit kit or pre-installed in the inverter.

* For information on which of the supported SMA inverters (see Section 2.4) support the Modbus interface of the Speedwire/
Webconnect data module, refer to the datasheet "SMA_Modbus-DB-en.xlsx" at www.SMA-Solar.com.
