The Speedwire/Webconnect Piggy-Back is a Speedwire communication interface with Webconnect
function for select SMA 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:
- In small-scale PV plants via a router with Internet connection
- In large-scale PV power plants via the Cluster Controller
The Speedwire/Webconnect Piggy-Back can only be used in the following inverters with at least the specified firmware version:
