Name of Alarm and Cause Solution
- 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 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.
- 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 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.
