SMA SPEEDWIRE/WEBCONNECT Piggy-Back
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.
