transmission between the products and Sunny Portal via the data logger (e.g.,
SMA Data Manager) or distributing the inverters over several systems. If there is an existing WLAN
or Ethernet connection, you can directly access your visualized system via the web browser on your
end device.
WLAN connection to SMA 360° app
The product has a QR code. By scanning the QR Code attached to the product via the SMA 360°
app, access to the product is established via WLAN and the connection to the user interface is
made automatically.
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.
Limited function in the event of frost
The integrated WLAN interface of the product is only designed for temperatures down to
-20°C.
• Deactivate the WLAN interface at low temperatures (see Section 8.6, page 60).
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
Grid management services
The product 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.
All-pole sensitive residual-current monitoring unit
The all-pole sensitive residual-current monitoring unit detects alternating and direct differential
currents. In single-phase and three-phase inverters, the integrated differential current sensor detects
the current difference between the neutral conductor and the line conductor(s). If the current
difference increases suddenly, the inverter disconnects from the utility grid.
4.4 LED Signals
The LEDs indicate the operating state of the product.
