2.2 Data monitoring and transmission
In system with more than one inverter, remote monitoring can be implemented through
a sophisticated communication system based on an RS-485 serial interface. A USB
port is available in the inverter to facilitate access during installation. An optional
AURORA Easy-Control system is also available for remote monitoring via the
Internet, analogue modem or GSM digital modem.
2.3 Technical Description
Figure 4 shows a block diagram of the AURORA inverter. The main elements are the
input DC-DC converters (further “boosters”) and the output DC-AC inverter. Both the
DC-DC converters and the output inverter operate at high switching frequency to
enable a compact design and relatively low weight.
Foe increased conversion efficiency, the version of the AURORA inverter does not
have a transformer therefore no galvanic isolation is provided between the input and
output. However, the AURORA inverter is equipped with the necessary safety features
to ensure safe operation in compliance with all applicable regulations without an
isolation transformer.
