Solution
E018
Ground Fault
Leakage current fail
The alarm is generated when,
during normal operation of the
inverter, a ground leakage cur-
rent is detected in the DC sec-
tion of the system. The alarm is
accompanied by the lighting up
of the red LED on the front of the
inverter. The inverter may even
also generate the E018 alarm
message for AC leakage currents
associated with the capacitive
nature of the photovoltaic array
compared to ground.
If possible, measure the insulation resistance us-
ing a megohmmeter positioned between the photo-
voltaic field (positive terminal short-circuited to the
negative pole) and ground.
If the measured value is less than 1 megohm, the
PV array must be checked by a technician/installer
to identify and eliminate the problem.
If the measured value is greater than 1 megohm
and the error warning continues to be present, con-
tact customer service.
E019
Self-Test Error 3
Leakage current
sensor self- test fail
Before connecting to the grid, the
inverter carries out an autotest
that tests the leakage current
sensor. The test is carried out by
“forcing” a current of known value
in the leakage current sensor: the
microprocessor compares the
read value with the known value.
The error is generated if the com-
parison between the read value
and the known value during the
test is not within the allowed tol-
erance.
This is an error inside the inverter that cannot be
checked externally. If the problem persists (after
switching the inverter off and then on again), con-
tact customer service. By its nature, the alarm ap-
pears only before connection to the grid.
E020
Self-Test Error 1
Booster relay self-
test fail
Before connecting to the grid, the
inverter carries out some internal
tests. One of these tests regards
the correct operation of the boost
relay. The test is carried out by
“forcing” the switching of the re-
lay and checking its functionality.
The error is generated if a prob-
lem is found with the operation of
the relay.
This is an error inside the inverter that cannot be
checked externally. If the problem persists (after
switching the inverter off and then on again), con-
tact customer service. By its nature, the alarm ap-
pears only before connection to the grid.
E021
Self-Test Error 2
Inverter relay self-
test fail
Before connecting to the grid, the
inverter carries out a test that re-
gards the operation of the invert-
er relay. The test is carried out by
“forcing” the switching of the relay
and checking its functionality. The
error is generated if a problem is
found with the operation of the
relay.
This is an error inside the inverter that cannot be
checked externally. If the problem persists (after
switching the inverter off and then on again), con-
tact customer service. By its nature, the alarm ap-
pears only before connection to the grid.
