Installation Manual SB25-30TLST-21-IA-en-13 21
4.8 Slot for 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, an SMA Power Control Module or a fan retrofit kit. The multi-function
interface can be retrofitted or installed at the factory according to a specific order.
Multi-Function Relay
You can configure the multi-function relay for various operating modes. The multi-function relay is
used, for example, to switch on or off operation or fault indicators which are required by standards
in some countries, e.g. IEC 62109-2 (for information on installation and configuration, see installation
manual of the multi-function relay). In order to meet the requirements of IEC 62109-2, either the
multi-function relay must be used as fault indicator and configured accordingly or a connection to
Sunny Portal must be available and the fault alarm via e-mail must be activated in Sunny Portal
(for information on fault alarm via e-mail, see the Sunny Portal user manula at www.SMA-Solar.com).
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).
Fan Retrofit Kit
The fan retrofit kit is used for additional inverter cooling at high ambient temperatures and also has a
multi-function relay (for information on installation and configuration, see the fan retrofit kit installation
manual). The fan retrofit kit and the SMA Power Control Module cannot be operated in parallel.
4.9 Operating Parameters
Various operating parameters control the functionality of the inverter. Apart from the country data set,
the operating parameters of the inverter can only be adjusted using an SMA communication product
(information on the parameters can be found in the Technical Description "Measured Values, Operating
Parameters and Event Messages" at www.SMA-Solar.com). You can adjust the country data set before
commissioning or within the first ten feed-in hours via two rotary switches in the inverter (see Section
6.5.2 "Setting the Country Standard and Language using the Rotary Switches" (page 49)).
4.10 Grid Management
The inverter is equipped with grid management functions.
Depending on the requirements of the network operator, you can activate and configure these
functions (e.g. provision of reactive power, active power limitation) via operating parameters.
For detailed information on the parameters of these functions, see the Technical Description
"Measured Values, Operating Parameters and Event Messages" at www.SMA.de/en in the
"Technical Description" category of the respective inverter.
