Data Transmission and Check

When more than one inverter is used, remote monitoring can be implemented through
a sophisticated communication system based on an RS-485 serial interface. An
optional Aurora Easy-Control system is also available for remote monitoring via the
Internet, analog modem or GSM digital modem.

AURORA Technical Description

Figure 4 shows a block diagram of AURORA. The main blocks are Dc-Dc input
converters (also called "boosters") and the output inverter. Both DC-DC converters
and output inverter operate at a high switching frequency to enable a compact design
and relatively low weight.
This version of AURORA does not include a transformer, i.e. with no galvanic
insulation between input and output. Without the transformer, conversion system
efficiency is further enhanced. Moreover AURORA is equipped with protections to
guarantee safe operation and compliance with safety standards, even without the
transformer, as described in the paragraph about protections.
