- 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 sufficient 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 significantly higher than the activation
voltage, contact customer assistance.

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
influenced by the environmental conditions, so must
be made under the same conditions in which the error
occurred.
- If the value measured is lower than 75kOhm, 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 75kOhm 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.
- E020
- Internal error

Yellow LED
Failure of the test on the relay of the “Booster” (DC-DC
circuit):
Before connecting to the grid, the inverter carries out
some internal tests. One of these tests concerns the
correct operation of the booster relay. The test is carried
out by “forcing” the switching of the relay and checking
its operation.
The error is generated if a problem is found in actioning
the relay.
• 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.
- E021
- Internal error

Yellow LED
Failure of the test on the inverter's relay (DC-AC circuit):
Before connecting to the grid, the inverter carries out
some internal tests. One of these tests concerns the
correct operation of the inverter relay. The test is carried
out by “forcing” the switching of the relay and checking
its operation.
The error is generated if a problem is found in actioning
the relay.
• 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.
- E022
- Internal error
-
Yellow LED
Timeout of the tests undertaken on the relays inside the
inverter:
Execution time for the self-test carried out on the relay
of the DC_AC (inverter) circuit too high. It may indicate
a problem connected to the aforementioned relays
• 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.
