[PVI-XXX.0-YY(-TL) - Rev:1.0]
The left cartridge refers to the high module,
while the right cartridge refers to the lower
module.
In the Master-slave version a single
OVR device is provided. In this case,
the fault signalling takes place on
both displays of the framework.
16.1.4.2 Check of the AC fuses
For this inspection, it is not necessary to
open the AC panel and switch off the
inverter: you can visually check if the fuses
are intact through the appropriate windows
(Figure 16-5).
The state of the fuse is signalled by a small
lever above each fuse: when the fuse is
intact, the lever is horizontal and attached
to the fuse box; in case of interruption the
lever will be vertical.
16.1.4.3 Check of the DC fuses
In case of a broken fuse, the inverter could
fail to detect sunlight and always indicate
that there is no sun.
For this inspection, it is necessary to open
the AC panel and switch off the inverter: you
can visually check if the fuses are intact
through the appropriate windows (Figure
16-5).
16.1.5
Check of warning cards
and signalling devices
Check that all labels bearing warnings or
indications are intact and well bonded to
the chassis of the inverter. In particular, the
danger labels should always be clearly
visible.
16.2.
Replacement of faulty battery
NOTICE
This component must be replaced only by a
qualified technician.
To remove the battery, the module must be
withdrawn from its seat.
Each 55kWp module present in the inverter
has a Lithium buffer battery of CR203 type2.
Its function is to keep the internal watch
powered for statistical calculations.
If the system signals “Battery Fail” on the
display, contact your dealer for possible
replacement.
If the battery fails, the system will
still function, even if the energy data
will not be correct.
