Red LED
Ground Fault The alarm is triggered when a ground
dispersion current is detected in the DC
section of the system.
The alarm is accompanied by light-up of
the red LED on the front of the inverter.

Input Over
voltage
This alarm is triggered when the inverter
input voltage (from the wind turbine)
exceeds the threshold set for proper
operation. The alarm is triggered before
reaching the absolute threshold beyond
which the inverter will be damaged.
When the inverter input voltage exceeds
the Over Voltage threshold, the inverter
will not start because the alarm is
triggered.
It is necessary to measure the input voltage inside the
inverter using a voltmeter.
If it is higher than the maximum operating range voltage the
alarm is genuine and the configuration of the wind turbine
must be checked.
If it is lower than the maximum operating range voltage the
alarm is induced by an internal malfunction and you should
contact the Power-One Service

Parameters
Error
The main microcontroller is not able to
initialise the two DSPs (booster stage
and inverter stage) properly.
This is usually due to communication
problems on the inverter’s internal bus.
This is an internal error in the inverter that cannot be verified
externally. If the problem persists (even after the inverter
has been turned off and then on again), contact the PowerOne Service.
Bulk OV
E004
Bulk Over
voltage
Internal error in the inverter. The alarm is
triggered when the voltage at the ends of
the bulk condensers exceeds the Over
Voltage threshold.
The alarm may be due to causes external to the inverter. an
excessive inverter input voltage may be read as a state of
over voltage for bulk capacities. In this case it is advisable
to check the inverter input voltage. If the value is close to
the input OV threshold the wind turbine configuration should
be adjusted.
The alarm may also be due to causes internal to the inverter,
and in this case it is necessary to contact the Power-One
Service.

or in the input voltage, but it is not due to a malfunction
in the inverter.If the error is repeated frequently, consult
the AN “Riso and Ileak Troubles Solving Guide” on
the Power-One web portal (www.power-one.com).
If the error relates to an internal malfunction it will continue
to occur, and it is therefore necessary to contact the PowerOne Service.

The alarm may be due to causes
external to the inverter. a reduced input
voltage in the inverter (only slightly
higher than the activation voltage) that is
not accompanied by a sufficient supply
of power from the wind turbine (a state
typical of periods of low wind).
If the error message is triggered sporadically this may be
due to causes outside the inverter (low wind and therefore
low availability of power for the wind turbine). If the problem
is repeated systematically even in the presence of high
wind and with an input voltage significantly higher than the
activation voltage, contact the Power-One Service.

Check the connections on the DC side of the inverter and
repeat the commissioning procedure.
Check that the safeguards used to protect against transitory
external over voltages are adequate and in a proper state
of repair. Remove them and try again. Replace them if
necessary.
If the error is repeated frequently, consult the AN “Riso and
Ileak Troubles Solving Guide” on the Power-One web portal
(www.power-one.com).
