2 Safety
2.1 Intended Use
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 inverter still complies with the standard after the product has been installed.
For safety reasons, it is not permitted to modify the product or install components that are not explicitly
recommended or distributed by SMA Solar Technology AG for this product.
The type label must remain permanently attached to the product.
Use the Speedwire/Webconnect data module only in accordance with the enclosed documentation
and with the local standards and directives. Any other application may cause personal injury or
property damage.
The enclosed documentation is an integral part of this product.
• Read and observe the documentation.
• Keep the documentation in a convenient place for future reference.
2.2 Safety Precautions
This section contains safety precautions that must be observed at all times when working on or with
the product. To prevent personal injury and property damage and to ensure long-term operation of
the product, read this section carefully and follow all safety precautions at all times.
Danger to life due to electric shock when opening the inverter
High voltages are present in the conductive components of the inverter. Touching live components
results in death or serious injury.
• Prior to performing any work on the inverter, always disconnect the inverter from all voltage
sources on the AC and DC sides (see inverter installation manual). Observe the waiting time
to allow the capacitors to discharge.
