4 Product Overview
SMA Solar Technology AG
Operating manual SBxx-1AV-41-BE-en-12 19
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
RS485 Interface
The inverter is equipped with an RS485 interface as standard. The inverter can communicate via
cables with SMA communication products or with up to three gateways for the TS4 module
technology via the RS485 interface (information on supported SMAproducts at www.SMA-
Solar.com).
Integration of TS4-R module technology
The inverter is equipped with an RS485 interface and the Cloud Connect function as standard to
integrate the TS4 module technology. Up to three gateways in line topology can be connected to
the inverter via the RS485 interface. The use of a separate Cloud Connect Advanced
communication unit is not required. The Cloud Connect function has the following functions:
• Easy integration of the TS4 module technology components into the system
• Easy commissioning and configuration via the user interface of the inverter
• Visualization and monitoring via Sunny Portal
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.
Parallel Operation of the DC Inputs A and B
You have the option of operating the inverter DC inputs A and B in parallel. As a result, and as
opposed to normal operation, several parallel-connected strings can be connected to the inverter.
The inverter automatically detects the parallel operation of the DC inputs A and B.
