4.2 Interfaces and Functions
The inverter can be equipped or retrofitted with the following interfaces and functions:
BLUETOOTH
Via BLUETOOTH, the inverter can communicate with various BLUETOOTH devices (for information
on supported SMA products, see www.SMA-Solar.com).
SMA Speedwire/Webconnect
The inverter is equipped with SMA Speedwire/Webconnect as standard. SMA Speedwire/
Webconnect is a type of communication based on the Ethernet standard. This enables inverter-
optimized 10/100Mbit data transmission between Speedwire devices in PV systems and the
software Sunny Explorer. The Webconnect function enables direct data transmission between the
inverters of a small-scale system and the Internet portal SunnyPortal without any additional
communication device and for a maximum of four inverters per SunnyPortal system. In large-scale
PV power plants, data transmission to the Internet portal SunnyPortal is carried out via the
SMAClusterController. You can access your SunnyPortal system from any computer with an
Internet connection.
SMA Speedwire/Webconnect enables, for PV systems operated in Italy, the connection to or
disconnection of the inverter from the utility grid and definition of the frequency limits to be used
with IEC61850-GOOSE messages.
RS485 interface
The inverter can communicate via cables with special SMA communication products via the RS485
interface (information on supported SMAproducts at www.SMA-Solar.com). The RS485 interface
can be retrofitted.
Grid Management Services
The inverter is equipped with service functions for grid management.
Depending on the requirements of the grid operator, you can activate and configure the functions
(e.g. active power limitation) via operating parameters.
