4 Product Overview
SMA Solar Technology AG
Installation Manual SBSxx-US-10-IA-xx-12 17
SMA Webconnect
The inverter is equipped with a Webconnect function as standard. The Webconnect function
enables direct data transmission between the inverters and Internet portals SunnyPortal and
SunnyPlaces without any additional communication device and for a maximum of 1 inverters per
visualized system. In PV systems with more than 1 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. 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 two Modbus interfaces.
One interface can be controlled via Ethernet and the other interface via RS485. The Modbus
interface via Ethernet is designed for industrial use – via SCADA systems, for example – and
deactivated as standard. The Modbus interface via Ethernet must be configured via the user
interface of the inverter (if necessary). The Modbus interface via RS485 is used for data exchanges
with an energy meter. The Modbus interface via RS485 must be configured via the user interface of
the inverter and set on the energy meter accordingly.
The Modbus interface via Ethernet has the following tasks:
• Remote query of measured values
• Remote setting of operating parameters
• Setpoint specifications for system control
• Controlling the battery
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.
