485 Data Module Type B or SMA Power Control Module
The 485 Data Module Type B is a communication interface which enables wired communication
via RS485 with special communication products (for information on installation and wiring, see
installation manual of the 485 Data Module Type B and RS485 cabling plan at www.SMA-
Solar.com). Depending on the type of communication, the operating parameters and messages are
displayed differently on the communication products.
Example: How the country data set parameter is displayed
For communication with RS485: parameter CntrySet
For communication via Bluetooth or Speedwire/Webconnect: parameter Set country standard
The SMA Power Control Module enables the inverter to perform grid management services (for
information on installation and configuration, see the installation manual of the
SMA Power Control Module at www.SMA-Solar.com).
If you want to use the 485 Data Module Type B or SMA Power Control Module in parallel with the
multifunction relay in the inverter, you must ensure that no more than 30 V DC or 25 V AC are
connected to the multifunction relay.
Multifunction relay
The multifunction relay is designed for several operating modes which you can select according to
your requirement. All operating modes are described in another section (see Section 8.6, page 45
). There is a different connection procedure depending on which operating mode you select (see
Section 6.5.1 "Connection Options for the Multifunction Relay", page 31).
The operating mode of the multifunction relay is set by default to Fault Indication or FltInd. If you
choose a different operating mode, you must use a communication product to set the operating
mode of the multifunction relay after commissioning, and adjust further settings for the operating
mode, if necessary (see Section 8.6 "Setting the Operating Mode of the Multifunction Relay",
page 45).
Error message required by standard
In some countries, signaling of errors is required by standards, e.g. IEC 62109-2.
• In order to meet the requirements of IEC 62109-2, a display device signaling an error
must be connected to the multifunction relay or the inverter must be registered in
Sunny Portal where the fault alert must be activated (for information on fault alert via
Sunny Portal, see Sunny Portal user manual at www.SMA-Solar.com).
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.
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.
