(PVI-10.0/12.0-I-OUTD(-S)-400 Rev:1.3)
The block diagram shows the AURORA PVI-10.0/12.0-I-OUTD-S-400 model
with two independent converters on DC-DC input. Each of these converters is
dedicated to a separate array with an independent Maximum Power Point Tracking
(MPPT) control. This means that the two arrays can be installed in different
positions, facing in different directions. Each array is controlled by an MPPT
control circuit.
Due to the size and high efficiency of AURORA thermal dissipation system, this
inverter guarantees operation at maximum power in a wide range of ambient
temperatures.
The inverter is controlled by two independent DSPs (Digital Signal Processors),
and by a central microprocessor.
Connection to the power supply grid is thus controlled by two independent
controllers, in full compliance with the regulations current for electrical power
supply and its safety.
AURORA operating system communicates with related components in order to
carry out data analysis.
All of this ensures the optimal operation of the entire system, as well as a high
yield in all isolation and load conditions, always fully respecting the relevant
directives, laws, and regulations.

Protections
2.4.1
Anti-Islanding
In the event of a failure in the local distribution grid due to the power supply
provider, or if the machine is shut down for maintenance operations, AURORA
must be physically disconnected in a safe manner, in order to guarantee the
protection of those working on the grid, all in full compliance with the applicable
national standards and laws. In order to avoid any islanding operations, AURORA
is equipped with an automatic disconnection system, a protection known as “Anti-
Islanding”.
The AURORA PVI-10.0/12.0-I is equipped with an advanced anti-islanding
protection system, all in accordance with the relevant national standards and laws.
