SMA Solar Technology AG
The system must be registered in the classic Sunny Portal if the inverter is integrated into a local
network and connected to the Internet via this network. With this connection, you have the
possibility to view the data online in real time.
If the inverter is connected to the Internet via the cellular network, you must register the system in
Sunny Portal powered by ennexOS. The communication with the inverters is optimized with regard
to the data volume and availability of the inverter. No data can be viewed in real time. Note that
the inverter must be equipped with a firmware version ≥ 2.04.88.R for connection via the cellular
network.
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
The inverter can be retrofitted with the SMA RS485 Module.
By installing the SMA RS485 Module, the inverter is able to communicate with the energy meter of
the SMA Revenue Grade Meter Kit.
Class 1 wiring methods are to be used for field wiring connection to the terminals of the
communication interface.
