Data transmission and check
In case multiple inverters are used, they can be monitored remotely by using an
advanced communication system based on the RS485 serial interface or on the Power
Line Modem (PLM) technology. For further information, refer to the corresponding
sections of this manual.

AURORA Technical Description
Figure 4 shows the AURORA block diagram. The main blocks are given by the input
Dc-Dc converters (also known as “booster”) and the output inverter. Both the Dc-Dc
converters and the output inverter work at high switching frequency to minimize size
and weight.
This model of AURORA is transformer-less, that means that there is no galvanic
isolation between input and output. This allows an increase in the inverter efficiency.
AURORA, on the other hand, is equipped with all the protection needed to operate
safely and to comply with existing safety regulations even without an isolation
transformer, as described in the paragraph regarding protective devices.
