- Error code
- Error message Name of Alarm and Cause
- Warning
Battery unit blocked through low state of health
- W054 (SOH):
- SOH Low ( Fault ) Indicates that the SOH level of the battery unit (during
- normal operation) is below the threshold for use. The
alarm is displayed for SOH values below 60%.
- W055
State of charge (SOC) of battery unit low:
- Battery Low ( 0% )
Indicates that the battery is completely dead.
- No Icon
Problem with battery unit (power) connection
- W056
cables:
- Power Engage
Error detected on the power cables between the
- (On)
inverter unit and the battery unit.
- W059 Overload on Backup output:
- Output power The alarm occurs when there is an excessive request
Overload for power by the grid with the inverter in "Backup"
- (On) mode.
State of health (SOH) of battery unit low:
- W060
Indicates that the SOH level of the battery unit (during
- COMMISSIONING -
system commissioning) is close to the threshold below
SOH test - Warning
which it cannot be used. The alarm is displayed for

SOH values between 51 and 60%.
Battery unit blocked through low state of health
- W061
(SOH):
- COMMISSIONING -
Indicates that the SOH level of the battery unit (during
SOH test - Fault
system commissioning) is below the threshold for use.
- No Icon
The alarm is displayed for SOH values below 50%.
Disconnection of the battery did not occur:
- W062
Impossible to disconnect the battery unit (via the
- BMS Shutdown err
system's internal devices) following a command

Input over-current (photovoltaic generator):
- E001
The alarm occurs when the inverter's input current
- Input OC
exceeds the inverter's threshold for maximum input
- (On)
current.
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.
- E002
The alarm is triggered before reaching the absolute
- Input OV
threshold beyond which the inverter will be damaged.
- (On)
When the inverter's input voltage exceeds the Over
Voltage threshold, the inverter will not start up due to
the generation of the alarm.
DSP initialisation error:
- E003 The main microcontroller is unable to correctly
- No Parameters initialize the two DSPs (booster stage and inverter
- (On) stage). The error is caused by communication
problems on the inverter's internal bus.

installed, it is advisable to force the battery to recharge using
the electrical grid (charge in AC). Otherwise it is necessary to
have good energy production and low absorption of domestic
loads to carry out the recharging of the battery (charge in DC).
and the battery unit. Particularly check the connectors have
been installed correctly and that there are no breaks in the
cables connecting the two units.
- If the problem persists (once the inverter has been switched
off and back on again), contact customer assistance.
- If the problem persists (once all loads have been
disconnected and the inverter has been switched off and back
on again), contact customer assistance.

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
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.
- If the problem persists (once the inverter has been switched
off and back on again), contact customer assistance.
