- Error message
- Warning
Name of Alarm and Cause Solution
- W059
- Output power
Overload
- Yellow LED
Overload on Stand-alone output:
The alarm occurs when there is an excessive request
for power by the grid with the inverter in "Stand
Alone" mode (this can only be seen if the Stand Alone
accessory board has been installed).
• Disconnect one or more loads from the Stand Alone output.
- If the problem persists (once all loads have been
disconnected and the inverter has been switched off and back
on again), contact customer assistance.

SOH test - Warning
- No LED
* text “Bat. Warn-
SOH_L" shown on the
display in the general
information (cyclical
screens)
State of health (SOH) of battery pack low:
Indicates that the SOH level of the battery pack
(during system commissioning) is close to the
threshold below which it cannot be used. The alarm is
displayed for SOH values between 51 and 60%.
• Indicates that the useful life of the battery is about to end as
with SOH values of below 50% it should be replaced.

SOH test - Fault
- No LED
* text “Bat. Fault-
SOH_L" shown on the
display in the general
information (cyclical
screens)
Battery pack blocked through low state of health
(SOH):
Indicates that the SOH level of the battery pack
(during system commissioning) is below the threshold
for use. The alarm is displayed for SOH values below
50%.
• Indicates that the useful life of the battery is over and it must
be replaced.
- W062
- BMS Shutdown err
- No LED
Disconnection of the battery did not occur:
Impossible to disconnect the battery pack (via the
system's internal devices) following a command
(automatic or manual).
• 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.
- W063
- Force Grid
Disconnection for SA
Request
- Yellow LED
Forced disconnection from grid:
The inverter disconnects from the grid following a
command input in stand-alone mode
• This warning is not of an error but is a message informing
that the inverter has been forced to disconnect from the grid to
go into stand-alone mode

- Battery Firmware
Update Failed
- Flashing yellow
LED
* “BMS FW UPDT
ERR.” shown on the
display in general
information (cyclical
screens)
Update of battery unit rmware failed:
Indicates that the update of battery unit rmware has
failed.
• Redo the battery unit rmware update procedure.
If the error warning is shown again contact customer
assistance to check the new rmware's compatibility.

Input over-current (photovoltaic generator):
The alarm occurs when the inverter's input current
exceeds the inverter's threshold for maximum input
current.
• Check whether the composition of the PV generator enables
input current which exceeds the maximum threshold allowed
by the inverter and that the conguration of the inputs
(independent or in parallel) is carried out correctly.
- If both checks are positive, contact customer assistance.
- E002
- Input OV
- Yellow LED
Input overvoltage (photovoltaic generator):
The alarm is generated when the input voltage (from
the PV generator) exceeds the inverter's threshold of
maximum input voltage.
The alarm is triggered before reaching the absolute
threshold beyond which the inverter will be damaged.
When the inverter's input voltage exceeds the Over
Voltage threshold, the inverter will not start up due to
the generation of the alarm.
• It is necessary to measure the input voltage inside the
inverter with a voltmeter.
- If it is higher than the maximum voltage of the operating
range, the alarm is genuine and it is necessary to check the
conguration of the PV generator. If the voltage has also
exceeded the maximum input threshold the inverter could be
damaged.
- If it is lower than the maximum voltage of the operating
range, the alarm is caused by an internal malfunction and it is
necessary to contact customer assistance.
- E003
- No Parameters
- Yellow LED
DSP initialisation error:
The main microcontroller is unable to correctly
initialize the two DSPs (booster stage and inverter
stage). The error is caused by communication
problems on the inverter's internal bus.
• 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.
