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.
