4.2 Interfaces and Functions

The inverter is equipped with the following interfaces and functions:

Web server with user interface for configuration

The inverter is equipped as standard with an integrated web server that enables configuration of the inverter via an individual user interface. The inverter user interface can be called up directly via the web browser in a computer, tablet PC or smartphone so long as there is a WLAN or Ethernet connection (see Section8 "Using the Inverter User Interface", page34).

SMA Speedwire

The inverter is equipped with SMA Speedwire as standard. SMA Speedwire is a type of communication based on the Ethernet standard. This enables inverter-optimized 10/100Mbit data transmission between Speedwire devices in PV systems and the inverter user interface.

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 system and the Internet portal SunnyPortal without any additional communication device and for a maximum of four inverters per SunnyPortal system. In large-scale PV power plants, data transmission between inverters and the Internet portal SunnyPortal is carried out via the SunnyHomeManager. You can access your SunnyPortal system from any computer with an Internet connection.

Webconnect enables - for PV systems operated in Italy - the connection or disconnection of the inverter to or from the utility grid and the specifying of the frequency limits to be used via IEC61850-GOOSE messages.

WLAN

The inverter 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 (see Section9.17 "Switching WLAN Off", page48). In addition, the inverter has a WPS (WiFi Protected Setup) function. The WPS function connects the inverter automatically with an end device (e.g. smartphone, tablet PC or computer). You can activate the WPS function by tapping on the enclosure lid twice in quick succession. The open interface will then be signalized via the rapid flashing of the blue LED on the inverter.

Operating Manual 13SB15-25-BE-en-10

4 Product Description

The integrated WLAN interface is only designed for temperatures down to -20°C.

• Deactivate the WLAN interface at low temperatures (see Section9.17 "Switching WLAN Off", page48).

SMA Solar Technology AG

Grid Management Services

The inverter 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.

SMAOptiTracGlobalPeak

SMAOptiTracGlobalPeak is an advancement of SMAOptiTrac and allows the operating point of the inverter to follow the optimal operating point of the PV array (MPP) precisely at all times. In addition, with the aid of SMAOptiTracGlobalPeak, the inverter detects several maximum power points in the available operating range, such as may occur particularly with partially shaded strings. SMA OptiTrac Global Peak is enabled by default.

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.

Connection of the SMAEnergyMeter

If an SMAEnergyMeter is installed in the PV system, the inverter can receive data on the household energy consumption directly from this.
