Data transmission and monitoring

If more than one inverter is used, they may be monitored, even remotely, by using
an advanced communication system which is based on the RS-485 serial interface.
The AURORA Easy-Control system is also available as an option, and allows the
remote monitoring of the system via the Internet or a GSM modem. Furthermore, a
system of radio monitoring is also available as an option (PVI-Desktop + PVI-
Radiomodule) to obtain a remote data display terminal, connected wirelessly.

Technical description of AURORA

Fig. 1 shows the block diagram of AURORA. The main blocks are the input DC-
DC converters (known as "boosters") and the output inverter. Both the DC-DC
converters and the output inverter work at a high switching frequency to enable a
compact design and a relatively low weight.
This version of AURORA has a high frequency transformer, i.e. a transformer with
galvanic isolation between input and output. The high frequency transformer allow
galvanic isolation between the primary (DC side) and the secondary (AC side),
maintaining very high performance in terms of energy yield and export. AURORA
is equipped with all of the protections necessary for a safe operation, in compliance
with the applicable regulations as described in the paragraph on protective devices.
