3.3 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.
The product user interface can be called up via the web browser if there is an existing connection
to an end device (e.g. computer, tablet PC or smartphone).
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
inverter 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 inverter has been commissioned.
Display of I-V characteristic curve
On the user interface of the product, a characteristic curve can be generated from current and
voltage values of the PV array per MPP tracker. Using this I-V characteristic curve, problems in the
PV array can be detected at an early stage.
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.
