BLUETOOTH
Via BLUETOOTH, the inverter can communicate with various BLUETOOTH devices (for information
on supported SMA products, see ). The BLUETOOTH interface can be
retrofitted.
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 10/100 Mbit 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 Sunny Portal without any additional
communication device and for a maximum of four inverters per Sunny Portal system. In large-scale
PV power plants, data transmission to the Internet portal Sunny Portal is carried out via the
SMA Cluster Controller. You can access your Sunny Portal 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 SMA products at 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.
Fault indicator relay
The inverter is equipped with a fault indicator relay which will signal faults depending on the type
of output device connected. You can connect your own load to this relay (e.g. warning light,
acoustic signal) (see Section 6.4 "Connecting the Fault Indicator Relay", page 28).
All-pole sensitive residual-current monitoring unit
The all-pole sensitive residual-current monitoring unit detects alternating and direct differential
currents. In single-phase and three-phase inverters, the integrated differential current sensor detects
the current difference between the neutral conductor and the line conductor(s). If the current
difference increases suddenly, the inverter disconnects from the utility grid.
