Monitoring and data transmission
User interface
The inverter is able to provide information about its operation through the
following instruments:
• Warning lights (luminous LEDs)
• LCD display showing operating data
• Mobile app and webserver
• Data transmission on the dedicated RS-485 serial line. The data can be
collected by a PC or a data logger equipped with an RS-485 port. Con-
tact the ABB support service with any queries about device compatibility.
Measurement tolerance
The data supplied by the inverter may differ from measurements taken
by certied measuring instruments (e.g. output meters, multimeters and
grid analysers); since the inverter is not a measuring instrument it has
wider tolerances for the measurements it makes.
The tolerances are generally:
±5% for real-time measurements with output power below 20%
±3% for real-time measurements with output power above 20%
±4% for all statistical data.
