Display Message Causes
E005 The alarm occurs when there
Comm.Error are communication problems be-
Internal Communi- tween the control devices inside
cation Error the inverter.
E006 The alarm appears when the in-
Output OC verter output current exceeds the
output overcurrent threshold of
Output Overcurrent the inverter.
E007 The alarm appears when one of
IGBT Sat the active devices of the inverter
IGBT Saturation is in saturation state.
E009 Error inside the inverter
Internal error
E010 Voltage at a specific part of in-
Bulk Low verter input circuit is not sufficient
Low Bulk Voltage for grid connection.
The alarm can be triggered by
causes external to the inverter:
a low inverter input voltage (just
above the activation voltage) that
is not accompanied by sufficient
availability of power from the pho-
tovoltaic array (typical condition
of periods of insufficient sunlight).
E011 Error inside the inverter regarding
Ramp Fail the time for starting steady state
Bulk ramp timeout operation of the DC-DC circuit
part (Boost).
It can be caused by an external
string voltage too low or due to
reduced power from PV arrays
(typically in the morning).
E012 Error inside the inverter regard-
DcDc Fail ing the operation of the DC-DC
Boost module error circuit part (Boost).
Solution
Error inside the inverter that cannot be checked ex-
ternally. If the problem persists (after switching the
inverter off and then on again), contact customer
service.
Error inside the inverter that cannot be checked ex-
ternally. If the problem persists (after switching the
inverter off and then on again), contact customer
service.
Once the error appears, the inverter attempts to
resume normal operation. If the error occurs spo-
radically, it may be caused by a sharp transition of
the grid voltage or the input voltage but is not at-
tributable to inverter malfunctioning. If the error is
associated with an internal fault, it will continue to
appear; contact customer service.
Error inside the inverter that cannot be checked ex-
ternally. If the problem persists (after switching the
inverter off and then on again), contact customer
service.
If the error warning appears sporadically, it can be
attributed to causes external to the inverter (insuf-
ficient sunlight, and therefore little power available
from the PV array).
If the problem appears systematically even in con-
ditions of high sunlight and with input voltage sig-
nificantly higher than the activation voltage, contact
customer service.
If the alarm is present early in the morning it could
be useful to increase the starting voltage to al-
low the grid connection of the inverter when more
power is available from the PV array. If the problem
persists (after switching the inverter off and then on
again), contact customer service.
