The Speedwire/Webconnect Piggy-Back is a Speedwire communication interface with SMA Webconnect function for Sunny Boy 3000-8000US and SB6000TL-11000TLUS (-10, -11 & -12) 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.
