(PVI-10.0/12.5-OUTD-xx Rev:1.2)
The block diagram shows model AURORA PVI-10.0/12.5-OUTD-xx with its two
input Dc-Dc converters and each converter is dedicated to a separate array with
independent Maximum Power Point Tracking (MPPT) control. This means that the
two arrays can be installed in different positions and orientations. Each array is
controlled by an MPPT control circuit. In the wind version, the two converters are
connected in parallel to rectifier output.
Thanks to its high efficiency and generously sized heat sink, the AURORA inverter
provides maximum power operation in a broad range of ambient temperatures.
The inverter is controlled by two independent DSPs (Digital Signal Processors) and
one central microprocessor.
Connection to the distribution grid is then monitored by two independent computers,
complying with the electrical standards both concerning system power supply and
safety.
AURORA operating system communicates with the relevant components to analyse
data.
This process ensures optimal performance levels of the whole units, as well as a high
efficiency under all insolation and load conditions, always in full compliance with the
applicable directives, standards and regulations.
