Interfaces and Functions
The inverter can be equipped or retrofitted with the following interfaces and functions:
User interface for configuration and monitoring
The product is equipped as standard with an integrated webserver, which provides a user interface for configuring and monitoring the product.
Once the connection has been established to the smart device, use a terminal (e.g. smartphone, tablet or laptop) to connect to the product's user interface using a web browser.
Smart Inverter Screen
The Smart Inverter Screen enables you to view the status display and to display the current power and consumption on the user interface login page. This gives you an overview of the most important product data without having to log into the user interface.
The Smart Inverter Screen is deactivated by default. The Smart Inverter Screen can be activated via the user interface once the product has been commissioned.
SMA Speedwire
The product is equipped with SMA Speedwire as standard. SMA Speedwire is a type of communication based on the Ethernet standard. SMA Speedwire is designed for a data transfer rate of 100 Mbps and enables optimum communication between Speedwire devices within systems.
The products supports the encrypted system communication with SMA Speedwire Encrypted Communication. In order to be able to use the Speedwire encryption in the system, all Speedwire devices, except for the SMA Energy Meter, must support the function SMA Speedwire Encrypted Communication.
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 13 inverters per visualized system. In PV systems with more than 13 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.
Wi-Fi
The product is equipped with a Wi-Fi 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 a smart end device.
Expanding the radio range in the WLAN network
In order to expand the radio range of the inverter in the WLAN network, you can install the Antenna Extension Kit accessory set in the inverter.
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
Module slots
The inverter is standard-equipped with two module slots. The module slots are located on the communication assembly and allow additional modules to be connected (e.g. SMA Sensor Module). The modules are available as accessories. The installation of two identical modules is not permissible.
Antenna Extension Kit
Within the WLAN network, the Antenna Extension Kit enables the radio range of the inverter to be upgraded (Information on assembly and connection see manual of the Antenna Extension Kit). The Antenna Extension Kit can be retrofitted.
SMA Sensor Module
The SMA Sensor Module has different interfaces for connecting various sensors (i.e. temperature sensor, irradiation sensor, anemometer or energy meter). The SMA Sensor Module converts the signals of the connected sensors and transmits them to the inverter. Information on installation, connection and configuration can be found in the manual for the SMA sensor module. The SMA Sensor Module can be retrofitted.
SMA I/O modules
The SMA I/O module enables the inverter to perform grid management services. Information on installation, connection and configuration can be found in the manual for the SMA I/O module. The SMA I/O Module can be retrofitted.
Multifunction Relay
The inverter is equipped with a multifunction relay as standard. The multifunction relay is an interface that can be configured for the operating mode used by a particular system.
SMA ShadeFix
The inverter is equipped with the shade management system SMA ShadeFix. SMA ShadeFix uses an intelligent MPP tracking system to determine the operating point with the highest output during shading conditions. With SMA ShadeFix, inverters use the best possible energy supply from the PV modules at all times to increase yields in shaded systems. SMA ShadeFix is enabled by default. The time interval of SMA ShadeFix is usually 6 minutes. This means that the inverter determines the optimum operating point every 6 minutes. Depending on the PV system or shading situation, it may be useful to adjust the time interval.
String-failure detection
The string-failure detection measures the total current of every input and continuously calculates the mean values for the inputs in question. The total currents are compared with the mean values. If a total current exceeds or falls short of the mean value by the set tolerance value, an event is reported. Marginally increased total currents are reliably detected over several query intervals and distinguished from typical current fluctuations of the PV array. String-failure detection is deactivated by default and must be activated. In addition, the tolerance value can be set via the user interface and the mean values read off.
Surge arrester type 1 and 2
On the AC and DC side, the inverter is equipped with slots for type 1 and 2 surge protection devices. The surge protection devices limit dangerous overvoltages. The surge protection devices can be retrofitted.
Universal mounting system (UMS_Kit-10)
The universal mounting system enables wall mounting of the inverter or serves as platform for higher mounting on the ground. The universal mounting system is available as an accessory.
