- E005 Communication error inside the inverter:
- Comm.Error The alarm occurs when there are communication prob-

The alarm occurs when the inverter's output current

exceeds the inverter's threshold for maximum output

Solution
• Error inside the inverter and cannot be checked externally.
- If the problem (once the inverter has been switched off and
back on) persists, contact customer assistance.
• Error inside the inverter and cannot be checked externally.
- If the problem (once the inverter has been switched off and
back on) persists, contact customer assistance.
Once the error occurs, the inverter tries to return to normal op-
eration.
- Should the error occur sporadically, it may be caused by a
brusque transition of the grid voltage or of the input voltage, but
is not due to a malfunction by the inverter.
- If the error is connected to an internal breakdown, it will con-
tinue to appear and so it is necessary to contact customer as-
sistance.
• Error inside the inverter and cannot be checked externally.
- If the problem (once the inverter has been switched off and
back on) persists, contact customer assistance.
- If the error signal occurs sporadically, it may be due to causes
external to the inverter (limited irradiation and so limited power
availability from the PV generator).
- If the problem occurs systematically also in conditions of high
irradiation and with input voltage which is significantly higher
than the activation voltage, contact customer assistance.
• Error inside the inverter and cannot be checked externally.
- If the problem (once the inverter has been switched off and
back on) persists, contact customer assistance.
• Error inside the inverter and cannot be checked externally.
- If the problem persists (once the inverter has been switched
off and back on again), contact customer assistance.
• Check that the setting of the "IN MODE" switch is specifically
set to "PAR" and that the bridges between the two input chan-
nels have been included.
- If the configuration of the inverter is correct, check that the
input strings have the usual number of standard panels of the
usual brand and with the same inclination/orientation.
- If both the configuration of the inverter and the characteristics
of the PV generator conform with the specifications, contact
customer assistance.
• Check that the inverter is not exposed to direct sunlight. Wait
for the temperatures to which the inverter is exposed to return
to the operating range and for the inverter to cool down.
- If the problem (once the ambient temperature has returned to
the range) persists, contact customer assistance. Remember
to wait the time needed to allow the inverter to cool down
• Error inside the inverter and cannot be checked externally.
- If the problem persists (once the inverter has been switched
off and back on again), contact customer assistance.
• Error inside the inverter and cannot be checked externally.

off and back on again), contact customer assistance.
- If the error signal occurs sporadically, it may be due to causes
external to the inverter (limited irradiation and so limited power
availability from the PV generator).

irradiation and with input voltage which is significantly higher
than the activation voltage, contact customer assistance.
