unctionality and components of the equipment
Configurable relay (ALARM relay)
The inverter is equipped with a configurable switching relay, which can be
used in different operating configurations that can be set in the dedicated
menu. A typical example of its application is closing the contact when an
alarm is triggered.
Remote switching on and off (Remote ON-OFF)
This command can be used to switch off/switch on the inverter via an
external (remote) command.
This function must be enabled in the menu and, when it is active,
switching on the inverter will not only be dictated by the presence of the
normal parameters that allow the inverter to connect to the grid, but will
also depend on the external on-off command.
Reactive power feed into the grid
The inverter is able to produce reactive power and can feed this power
into the grid when the phase factor is set. Managing the feed can be
controlled directly by the grid company via a dedicated RS485 serial
interface or set by the display or through the configuration software,
Aurora Manager LITE.
Power feeding management modes vary according to the country of
installation and the grid companies. For detailed information on the
parameters and characteristics of this function, please contact ABB
directly.
Limiting the active power fed into the grid
The inverter, if enabled and set using the display or the configuration
software, can limit the amount of active power fed into the grid by the
inverter to the desired value (expressed as a percentage).
Data transmission and control
The inverter or a network of several inverters can be monitored locally
or remotely by using the integrated web server or dedicated mobile app.
The system also has an RS-485 serial interface (public communication
protocol “Modbus RTU”).
SD card
The inverter is equipped with a slot for insertion of an SD Card memory.
The maximum size of the SD Card is 4 GB. Its main function is to allow
the inverter firmware to be updated in a few simple steps.
The most up-to-date inverter firmware version is available from the
