5 Product Overview SMA Solar Technology AG
Operating manual SHP-US-20-BE-en-10 20
SMA Webconnect
The inverter is equipped with a Webconnect function as standard. The Webconnect function
enables direct data transmission between the inverter and Sunny Portal without any additional
communication device and for a maximum of 4 inverters per visualized system. In PV systems with
more than 4 inverters, there is the option of establishing data transmission between the inverters
and Sunny Portal via the data logger (e.g., SMA Data Manager) or distributing the inverters over
several systems. You can directly access your visualized system via the web browser on your 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 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.
SMA Smart Connected
SMA Smart Connected is the free monitoring of the inverter via the SMA Sunny Portal. Thanks to
SMA Smart Connected, the PV system operator and qualified person will be informed automatically
and proactively about inverter events that occur.
SMA Smart Connected is activated during registration in Sunny Portal. In order to use SMA Smart
Connected, it is necessary that the inverter is permanently connected to Sunny Portal and the data
of the PV system operator and qualified person is stored in Sunny Portal and up-to-date.
5.4 LED Signals
The LEDs indicate the operating state of the inverter.
