WLAN
The product is equipped with a WLAN interface as standard. The inverter is delivered with the
WLAN interface activated as standard. If you do not want to use WLAN, you can deactivate the
WLAN interface.
In addition, the product has a WPS function. The WPS function is for automatically connecting the
product to a network (e.g. via router) and establish a direct connection between the product and
an end device.
Expanding the radio range in the WLAN network
In order to expand the radio range of the inverter in the WLAN network, you can install the
Antenna Extension Kit accessory set in the inverter.
Modbus
The product is equipped with a Modbus interface. The Modbus interface is deactivated by default
and must be configured as needed.
The Modbus interface of the supported SMA products is designed for industrial use – via SCADA
systems, for example – and has the following tasks:
• Remote query of measured values
• Remote setting of operating parameters
• Setpoint specifications for system control
Module slots
The inverter is standard-equipped with two module slots. The module slots are located on the
communication assembly and allow additional modules to be connected (e.g. SMA Sensor
Module). The modules are available as accessories. The installation of two identical modules is not
permissible.
SMA RS485 Module
With the assembly of the RS485 Module, the inverter can communicate with special
SMAcommunication products (Information on assembly and connection see manual of the SMA
RS485 Module). The SMA RS485 Module can be retrofitted.
Antenna Extension Kit
Within the WLAN network, the Antenna Extension Kit enables the radio range of the inverter to be
upgraded (Information on assembly and connection see manual of the Antenna Extension Kit). The
Antenna Extension Kit can be retrofitted.
Grid Management Services
The inverter is a grid support interactive inverter.
The inverter was tested in accordance with the UL1741 SA (2016-09-07) to be compliant with the
source requirements documents of the states available at the time. For connecting the inverter to the
utility grid, no additional grid monitoring equipment is necessary. A description of the tested
functions and instructions on the activation and setting of functions can be found in the technical
information "Grid Support Utility Interactive Inverters" at www.SMA-Solar.com.
