- E058
- Internal error

Yellow LED
Error in the check of Pin vs Pout:
The error occurs if the difference between
the measured value of input power and
that of output power is greater than the limit
imposed internally to the inverter.
• 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.
- E074
- Internal error

Yellow LED
Communication error inside the inverter:
The alarm occurs when there are
communication problems between the
control devices inside the inverter.
• 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.
- E077
- Internal Error
-
Yellow LED
Error in the system configuration:
Error inside the inverter
• 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.
- E078
- Riso Test fail
-
Yellow LED
Riso test error:
Problem detected during the Riso test
phase.
• 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.
- E079
- Wrong Sequence
-
Yellow LED
Incorrect Phases connection
(Only triphase models) The phases have
not been connected correctly to the AC
output
• Invert two of the phases of the network wiring to the AC
terminal block of the inverter.
- E084
- BackFeed OC
-
Yellow LED
Return current to photovoltaic field:
The error occurs if the input voltage is
particularly low (typically in the evening in
conditions of low irradiation) and indicates
a return current from the inverter to the
photovoltaic panels).
If the error occurs in the evening or in conditions of low
irradiation, it must not be considered a problem but a protection
intervention for the photovoltaic field.
- If the error occurs with good irradiation conditions, switch
the inverter off and back on again; if the error persists, contact
customer assistance.
8.10.3 Power limitation messages
The equipment can signal possible output power limitations which may occur on the basis of:
• settings made by the user
• settings required by the grid standard of the country of installation
• protective devices inside the inverter
The limitation messages can only be verified on the Web User Interface on “Status Summary” section (“MAIN menu”).
