2.1 Intended Use
The Speedwire/Webconnect Piggy-Back is a Speedwire communication interface with Webconnect
function for inverters.
Speedwire is a wire-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 plants.
The Webconnect function enables direct data transmission between the inverters of a small-scale plant
and the Internet portal Sunny Portal without any additional communication device and for a maximum
of four inverters per Sunny Portal plant. For this, a Speedwire/Webconnect Piggy-Back must be
installed in each of the inverters. You can access your Sunny Portal plant from any computer with an
Internet connection.
The Speedwire/Webconnect Piggy-Back fulfills the following tasks:
• Set-up of a Speedwire network in small-scale and large-scale PV power plants
• Data exchange with the Internet portal Sunny Portal:
– In small-scale PV plants 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 Speedwire/Webconnect Piggy-Back is available as a retrofit kit.
