Name of Alarm and Cause Solution
- E010
- Bulk UV
- Yellow LED
Low “Bulk” voltage (DC-DC circuit):
The alarm can be caused by causes external to
the inverter: a reduced input voltage on the inverter
(just above the activation voltage) but which is not
accompanied by a sufcient 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 even in conditions of
high irradiation and with input voltage which is signicantly
higher than the activation voltage, contact customer
assistance.
- E011
- Ramp Fault
- 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 persists (once the inverter has been switched
off and back on again), contact customer assistance.
- E012
- Internal error
- Yellow LED
Error in the “Booster” circuit (DC-DC side)
recorded by the “Inverter” circuit (DC-AC side):
Error inside the inverter regarding the operation of the
DC-DC circuit part (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.
- E014
- Over temperature
- Yellow 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
internally and is inuenced 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 persists (once the ambient temperature has
returned to within the range), contact customer assistance.
You must remember to wait for the time necessary to allow the
inverter to cool down.
- E015
- Cap. Fault
- Yellow LED
Breakdown recorded on the “Bulk” capacitor:
Error inside the inverter regarding 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
- Internal error
- Yellow LED
Error in the “Inverter” circuit (DC-AC side)
recorded by the “Booster” circuit (DC-DC side):
The alarm is generated when a problem is detected in
the inverter circuit part (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
- Internal error
- Yellow 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 can be caused by causes external to
the inverter: a reduced input voltage on the inverter
(just above the activation voltage) but which is not
accompanied by a sufcient 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 even in conditions of
high irradiation and with input voltage which is signicantly
higher than the activation voltage, contact customer
assistance.
- E018
- Leak fault
- Red 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
capacitive nature of the photovoltaic generator
compared to ground.
• Measure the isolation resistance using a megohmmeter
positioned in the photovoltaic array (positive terminal short-
circuited at the negative pole) compared to ground. The
measurement is strongly inuenced 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 generator to identify and eliminate the problem.
- If the value measured is higher than 1 megaohm and the
error signal persists, contact customer assistance.
- E019
- Internal error
- Yellow LED
Failure of test on sensor to measure the leakage
current (DC side):
Before connecting to the grid the inverter runs a
self-test regarding the sensor for the leakage current.
The test is carried out by “forcing", in the sensor of
the leakage current, a current with a known value:
the microprocessor compares the value read with the
known value.
The error is generated if the comparison between the
read value and the known value during the test does
not fall within the allowed tolerance.
• Error inside the inverter and cannot be checked externally.
By its nature, the alarm only occurs prior to connection to the
grid
- If the problem persists (once the inverter has been switched
off and back on again), contact customer assistance.
