SMA Solar Technology America LLC
SMA Webconnect
The inverter is equipped with a Webconnect function as standard. The Webconnect function
enables direct data transmission between the inverters of a small-scale plant and the Internet portals
Sunny Portal and Sunny Places without any additional communication device and for a maximum
of 1 inverters per visualized system. 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
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.
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 inverter is a grid support multi-mode 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.
Secure power supply operation
In case of a grid failure, the secure power supply operation supplies the loads with energy from the
battery. You can connect a standard outlet and a standard switch to the inverter. You can connect
a load with a maximum of 16 A and 120 V to the outlet. The load is supplied with energy form the
battery during grid failure. The switch is used to activate and deactivate secure power supply
operation.
The secure power supply operation is not automatically activated in the event of a grid failure,
neither is it automatically deactivated once the utility grid is available again. If the utility grid fails,
the load supply must be activated manually by activating the switch. The inverter automatically
regulates the energy supply of the outlet after activating the switch. When the utility grid is
available again and the load can be supplied by this again, the secure power supply operation
must be deactivated manually by switching the switch off.
