Input voltage (Vin) higher than booster voltage
E057 (Vbulk):
- Vbulk reading error
The error occurs if the input voltage exceeds the

inverter)
Error in the check of Pin vs Pout:
E058
The error occurs if the difference between the

- Yellow LED connected correctly to the AC output
Inverter fault / Incomplete inverter closing:
E081 Fault inside the inverter or incomplete inverter closing
- Internal Error (front cover missing or not tightened, cable glands
- Red LED missing or incorrectly tightened, environmental
protection IP65 not guaranteed)
Return current to photovoltaic field:
E084
The error occurs if the input voltage is particularly low

photovoltaic panels).
E103 RSD self-test fault:
- RSD self-test fault RSD functionality is damaged
- Yellow LED
Solution
• 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 persists (once the ambient temperature has
returned to within the range), contact customer assistance.
Remember to wait the time needed to allow the inverter to
cool down
• 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
configuration 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.
• 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.
- 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.
- 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.
- If the problem persists (once the inverter has been switched
off and back on again), contact customer assistance.
• Invert two of the phases of the network wiring to the AC
terminal block of the inverter.
• If the problem has occurred during the installation phase or
during the inverter maintenance phase (therefore the cover
has been removed or the cable glands have been acted
upon), carry out the following operations:
- Disconnect the AC grid and DC input from the inverter
and check for the front cover and all the cable glands, also
checking their correct tightening to ensure environmental
protection IP65; reconnect the AC grid and the DC input and
attempt to switch the inverter on; if the problem persists,
contact customer assistance :
- If the front cover and all cable glands are present, disconnect
the AC grid and DC input from the inverter and wait 15
minutes at a safe distance, then open the inverter cover and if
no smoke/smell of burning is present, check the integrity of the
components or the presence of moisture or other abnormal
conditions; reconnect the AC grid and DC input and attempt to
switch on the inverter; if the problem persists contact customer
assistance.
• If the problem has occurred after installation or after an
inverter maintenance phase (therefore the cover has NOT
been removed or the cable glands have NOT been acted
upon), disconnect the AC grid and the DC input from the
inverter and contact customer assistance.
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.
• 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.
