4.2 Interfaces and Functions

RS485 interface

The inverter can communicate via cables with special SMA communication products via the RS485
interface (information on supported SMA products at www.SMA-Solar.com). The RS485 interface
can be retrofitted.

SMA Speedwire/Webconnect

SMA Speedwire/Webconnect is a type of communication based on the Ethernet standard, and
allows you to connect the inverter to a Speedwire network. Webconnect allows for data exchange
between the inverter and Sunny Portal. Sunny Portal is an Internet portal which allows you to
monitor PV systems and to visualize and present PV system data.

Multifunction relay

You can configure the multifunction relay for various operating modes. The multifunction relay is
used, for example, to switch fault indicators on or off (for information on installation and
configuration, see installation manual of the multifunction relay). The multifunction relay can be
retrofitted.

SMA Power Control Module

The SMA Power Control Module enables the inverter to implement grid management services and
is equipped with an additional multifunction relay (for information on installation and configuration,
see the installation manual of the SMA Power Control Module). The SMA Power Control Module
can be retrofitted.

SMA OptiTrac Global Peak

SMA OptiTrac Global Peak is an advancement of SMA OptiTrac and allows the operating point of
the inverter to follow the MPP precisely at all times. In addition, with the aid of
SMA OptiTrac Global Peak, the inverter can detect the presence of several maximum power points
in the available operating range, such as may occur particularly with partially shaded strings.
SMA OptiTrac Global Peak is enabled by default.

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.

Surge arrester type II

Surge arresters of type II limit dangerous overvoltages. Surge arresters of type I can be retrofitted.
