- Error code
- Error message Name of Alarm and Cause
- LED status
Grid frequency outside of range:
- E028 Error in the internal measurement of the grid
- Internal error frequency (imposed by regulations) to have a
- Yellow LED measurement redundancy (2 measurements on the
same parameter carried out by two different circuits).
- E029 Internal overvoltage on the measurement of the
- Mid Bulk OV "Mid bulk":
- Yellow LED Error inside the inverter (only triphase models)
High leakage current (DC side):
- Error on the internal measurement (performed when
- E030 the inverter is connected to the grid) of the DC side
- Internal error
(PV generator) leakage current with respect to ground
- Yellow LED (required by regulations) to have a measurement
redundancy (2 measurements of the same parameter
carried out by two independent circuits)
Output relay damaged:
- E031 Measurement of internal voltage on heads of the
- Internal error output relay outside of range. There is too great a
- Yellow LED difference in voltage between the input and output of
the grid connection relay.
Imbalanced output currents:
- E032
Measurement of the unbalance in the output voltage
- Internal error
(made across the three phases) outside of range (only
-
Yellow LED
in three-phase models)
- E033
Low ambient temperature:
- Undertemperature
Temperature outside the inverter below -25°C
- Yellow LED
- E034
"IGBT" circuitry not ready:
- IGBT not ready
Error inside the inverter
-
Yellow LED
Inverter awaiting "remote ON" command:
- E035
The inverter has been switched off remotely (remote
- Remote Off
OFF) and remains in waiting state for the signal that
- Yellow LED
will switch it on again (remote ON).
Average of the measurements of grid voltage
outside of range:
The average value of the grid voltage (sampled every
10 minutes) does not fall within the permitted ranges.
- E036
The grid voltage in the point connected to the inverter is
- Internal error
too high. This may be caused by a grid impedance that
- Yellow LED
is too high. In the final stage of the timeout, the inverter
limits the power to check whether the grid voltage
has stabilised into regular parameters. If this does not
happen, the inverter disconnects from the grid
Low value of the isolation resistance (only with
the "Amorphous" mode activated):
This error can appear only if the "Amorphous" mode
is enabled. This function is enabled only in inverters
- E037
equipped with grounding kit and is used to monitor
- Riso Low
the voltage at the ends of the grounding resistor. The
- Red LED
error appears when the voltage at the ends of the
resistor connected between ground and pole of the
photovoltaic generator exceeds 30V for more than 30
minutes or 120V for more than one second.
Solution
• 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.
• 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.
• 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.
• 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.
• 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.
• Wait for the temperatures to which the inverter is exposed to
return to the operating range.
- If the problem persists, contact customer assistance. You
must remember to wait for the time necessary to allow the
inverter to warm up.
• 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.
• Switch the inverter back on remotely. If the unit does not
switch on, disable the remote on/off function and switch the
equipment off completely and then switch it on again.
- If the problem persists (once the Remote ON/OFF function
has been reactivated), contact customer assistance.
• Check the grid voltage in the connection point to the inverter.
- If the grid voltage differs from the range due to the conditions
of the distribution grid, ask the operator to adjust the grid
voltage. If the operator authorises a change to the inverter's
parameters, agree the new limits with customer assistance.
• Check for the presence and correct contact between the
two terminals of the grounding resistance installed inside the
inverter
• 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 1 megaohm, 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 1 megaohm and the
error signal persists, contact customer assistance.
