5.2.2 DC Box (B)
On the external front panel are fixed the
handles of the DC switches. The panel is
removable and allows access to the fuse box
and DC overvoltage dischargers.
5.2.3 55kWp Modules area (C)
This is the core of the PVI-XXX.0(-TL). Here,
there are two
1
DC/AC conversion modules
connected, capable of converting the
photovoltaic energy into electrical energy
compatible with the distribution grid.
Each module has several signal LEDs and an
interactive display. The modules can be
extracted by first removing the interlocking
front panel. This latter is provided with a
removable and washable filter.
5.2.4 AC Fuses area (D)
Removing this panel you can access the
fuses on the AC line of each module. In
addition, two transparent windows allow to
inspect if one or more fuses are faulty.

If there is a PVI-55.0(-TL) version, there is
only one module present.
5.2.5 Framework (E)
This group, called Framework, contains the
B, C and D areas and it may be complete
(100kW
version), or certain electro-
mechanical elements corresponding to the
superior module may be missing in the
upper part (50kW version).
5.2.6 Enumeration of the 55kWp
Modules
The enumeration of modules is similar to
the one indicated in Figure 5-1. The lower
module will always have the number 1,
while the final number depends on the
AURORA PVI-XXX.0(-TL) model (e.g. for the
model from 275kW the enumeration ranges
from 1 to 5).
NOTICE
The enumeration of modules must not be
confused with the serial number of the
single module. The use of enumeration of
single modules facilitates the connections
on the DC side (where there are labels
with the corresponding enumeration).
