6.6.2 Multi-Function Interface
The inverter is equipped with a slot for multi-function interfaces. This slot is designed to connect a
simple multi-function relay or an SMA Power Control Module. The interface can either be retrofitted,
installed at the factory according to a specific order, or included in the regular scope of delivery.
Multi-Function Relay
You can configure the multi-function relay for various operating modes. The multi-function relay is
used, for example, to switch fault indicators on or off (for information on installation and configuration,
see installation manual of the multi-function relay).
SMA Power Control Module
The SMA Power Control Module enables the inverter to implement grid management services and is
equipped with an additional multi-function relay (for information on installation and configuration,
see installation manual of the SMA Power Control Module).
6.6.3 Communication Interface
The inverter can optionally be fitted with an extra communication interface (e.g., RS485). This
communication interface enables the inverter to communicate with special SMA communication
products or other inverters (for information on supported products, see www.SMA.de/en).
The interface can either be retrofitted, installed at the factory according to a specific order, or included
in the regular scope of delivery.
You can only set the operating parameters of the inverter via SMA communication products. You can
set the country data set of the inverter via the two rotary switches in the inverter only prior to
commissioning or within the first ten operating hours.
Display of parameters
Depending on the type of communication, RS485 or Bluetooth, the parameters and
messages are displayed differently on the communication products.
Example of how the country data set parameter is displayed:
• For communication with RS485: "CntrySet" parameter
• If you are using Bluetooth: parameter "Set country standard"
