Name of Alarm and Cause Solution
- E001
- Input OC
- Yellow LED
Input over-current (photovoltaic generator):
The alarm occurs when the inverter's input current
exceeds the inverter's threshold for maximum input cur-
rent.
• 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 over-voltage (photovoltaic generator):
The alarm is generated when the input voltage (from the
PV generator) exceeds the inverter's threshold of maxi-
mum input voltage.
The alarm occurs before reaching the absolute threshold
over which the inverter is damaged.
When the inverter's input voltage exceeds the Over Vol-
tage 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gura-
tion 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 cannot initialise correctly 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 (once the inverter has been switched off and back
on) persists, contact customer assistance.
- E004
- Bulk OV
- Yellow LED
“Bulk” over-voltage (DC-DC circuit):
Error inside the inverter. The alarm is raised when the
voltage at the heads of the bulk capacitors exceeds
the Over Voltage threshold (internal unchangeable th-
reshold).
• The alarm may be triggered by causes external to the inverter:
- An excessive input voltage can be recorded as a condition for
bulk over voltage. In this case it is advisable to check the inver-
ter's input voltage and should this value be close to the input OV
threshold, review the conguration of the photovoltaic generator.
- Excessive grid voltage could cause the bulk voltage to rise in
uncontrolled fashion with a consequent protection intervention
and hence generation of the alarm. In these cases the alarm is
transitory and the inverter automatically restarts
- The alarm may be triggered by causes inside the inverter and in
this case it is necessary to contact customer assistance.
- E005
- Comm.Error
- Yellow LED
Communication error inside the inverter:
The alarm occurs when there are communication pro-
blems between the control devices inside the inverter.
• 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.
- E006
- Output OC
- Yellow LED
Output over current:
The alarm occurs when the inverter's output current
exceeds the inverter's threshold for maximum output
current.
• 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.
- E007
- IGBT Sat
- Yellow LED
Saturation recorded on the IGBT components:
The alarm occurs when one of the inverter's active devi-
ces is in a saturated state.
Once the error occurs, the inverter tries to return to normal ope-
ration.
- Should the error occur sporadically, it may be caused by a bru-
sque 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 continue
to appear and so it is necessary to contact customer assistance.
- E009
- Internal error
- Yellow LED
Error inside the inverter:
Error inside the inverter
• 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.
- E010
- Bulk Low
- Yellow LED
Low “Bulk” voltage (DC-DC circuit):
• The alarm may be triggered by causes external to the
inverter: a reduced input voltage on the inverter (just
above the activation voltage) but which is not accompa-
nied by a sufcient availability of power from the pho-
tovoltaic generator (typical condition of the stages with
limited irradiation)
- 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 signicantly higher than
the activation voltage, contact customer assistance.
- E011
- Ramp Fail
- Yellow LED
Long wait for “Booster” regime to start:
Error internal to inverter relating to start up time for DC-
DC circuit regime (Booster)
• 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.
- E012
- DcDc Fail
- Yellow LED
Error in the “Booster” circuit (DC-DC side) recorded
by the “Inverter” circuit (DC-AC side):
Error internal to inverter relating to operation of the DC-
DC circuit regime (Booster)
• 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.
