Alarm LED
Saturation recorded on the IGBT components:
The alarm occurs when one of the inverter's active de-
vices is in a saturated state.
Once the error occurs, the inverter tries to return to normal op-
eration.
- Should the error occur sporadically, it may be caused by a
brusque 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 con-
tinue to appear and so it is necessary to contact customer as-
sistance.
- E009
- Internal error

Alarm 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
-
Alarm 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 accom-
panied by a sufcient availability of power from the
photovoltaic 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 signicantly higher
than the activation voltage, contact customer assistance.
- E011
- Ramp Fail
-
Alarm 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
-
Alarm LED
Error in the “Booster” circuit (DC-DC side) record-
ed 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 persists (once the inverter has been switched
off and back on again), contact customer assistance.
- E013
- Wrong Mode
-
Alarm LED
Incorrect conguration of inputs (set in parallel
rather than independent):
The alarm is generated solely when the inverter is con-
gured with parallel inputs. In this particular congu-
ration the inverter checks the input voltage of each of
the two channels and if the two voltages differ by more
than 20Vdc, the alarm is raised .
• Check that the setting of the "IN MODE" switch is specically
set to "PAR" and that the bridges between the two input chan-
nels have been included.
- If the conguration of the inverter is correct, check that the
input strings have the usual number of standard panels of the
usual brand and with the same inclination/orientation.
- If both the conguration of the inverter and the characteristics
of the PV generator conform with the specications, contact
customer assistance.
- E014
- Over Temp.
-
Alarm LED
Excessive temperature inside the inverter:
External temperature over 60°C. This parameter also
depends on the power which the inverter must supply
since the measurement of temperatures is done inter-
nally and is inuenced by the heat dissipated by the
components of the inverter itself
• 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 (once the ambient temperature has returned to
the range) persists, contact customer assistance. Remember
to wait the time needed to allow the inverter to cool down
- E015
- Bulk Cap Fail
-
Alarm LED
Fault recorded on the “Bulk” capacitor:
Error inside the inverter relating to a problem in the bulk
capacitors.
• 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.
- E016
- Inverter Fail
-
Alarm LED
Error in the “Inverter” circuit (DC-AC side) record-
ed by the “Booster” circuit (DC-DC side):
The alarm is generated when a problem is recorded in
the inverter circuit (DC/AC)
• 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.
- E017
- Start Timeout
-
Alarm LED
Long wait for “Inverter” regime to start up:
Error internal to inverter relating to start-up time for the
DC-AC circuit regime (Inverter)
• 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 ac-
companied by a sufcient availability of power from the
photovoltaic 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 signicantly higher
than the activation voltage, contact customer assistance.
- E018
- Ground Fault
-
GFI LED
High leakage current measured on the DC side
(photovoltaic generator):
The alarm is generated when, during normal operation
of the inverter, a leakage current to ground is detected
in the DC section of the system. It is also possible that
the inverter generates the alarm E018 message also
due to AC leakage currents connected to the capaci-
tive nature of the photovoltaic generator compared to
ground.
• Measure the insulation resistance using a megohmmeter posi-
tioned in the photovoltaic eld (positive terminal short-circuited
at the negative pole) compared to ground. The measurement is
strongly inuenced by the environmental conditions, so must be
made under the same conditions in which the error occurred.
- If the value measured is lower than 1 megaohm, a check must
be carried out by a technician/installer on the photovoltaic gen-
erator to identify and eliminate the problem.
- If the value measured is higher than 1 megaohm and the error
signal persists, contact customer assistance.
