- E001Error codeE001 Input OC (Input Overcurrent)
- E002Error codeThis alarm is indicated when the inverter input voltage (coming from the PV array) exceeds the operating threshold. 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 generate the alarm and not start
- E003Error codeThe main microcontroller is unable to correctly initialize the two DSPs (boost stage and inverter stage). This is usually due to communication problems on the internal bus of the inverter
- E004Error codeError inside the inverter. The alarm is raised when the voltage at the ends of the bulk capacitors exceeds the Over Voltage threshold
- E005Error codeThe alarm occurs when there are communication problems between the control devices inside the inverter
- E006Error codeThe alarm appears when the inverter output current exceeds the output overcurrent threshold of the inverter
- E007Error codeThe alarm appears when one of the active devices of the inverter is in saturation state
- E009Error codeInternal error
- E010Error codeVoltage at a specifci part of inverter input circuit is not suffci ient 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 suffci ient availability of power from the photovoltaic array (typical condition of periods of insuffci ient sunlight)
- E011Error codeError inside the inverter regard ing the time for starting steady state 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)
- E012Error codeError inside the inverter regarding the operation of the DC-DC circuit part (Boost)
- E013Error codeIncorrect confgi uration of inputs (set in parallel ra ther than independent): The alarm is generated solely when the inverter is con fgi ured with parallel inputs. In this particular confgi ura tion the inverter checks the input voltage of each of the two channels and if the two voltages differ by more than 20Vdc, the alarm is raised
- E015Error codeBreakdown recorded on the “Bulk” capacitor: Error inside the inverter relating to a problem in the bulk capacitors
- E016Error codeError in the “Inverter” circuit (DC-AC side) recorded by the “Booster” circuit (DC-DC side): The alarm is generated when a problem is recorded in the inverter circuit (DC/AC)
- E017Error code
- E018Error codeHigh leakage current measured on the DC side (pho tovoltaic 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
- E019Error codeFailure of test on sensor to measure the leakage cur rent (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 micropro cessor 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
- E020Error codeFailure of the test on the relay of the “Booster” (DC- DC circuit): Before connecting to the grid the inverter carries out in ternal tests. One of these tests concerns the correct ope ration of the booster relay. The test is carried out by “for cing” the switching of the relay and checking its operation. The error is generated if a problem is found in actioning the relay
- E021Error codeBefore connecting to the grid, the inverter carries out a test that regards the operation of the inverter 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
- E022Error codeTime taken to execute the autotest carried out on the relays of the DC-AC circuit part (inverter) is too long. This may indicate a problem associated with the aforesaid relays
- E023Error codeThe error is generated if the direct component of the current supplied to the grid exceeds the threshold of 0.5% of the rated operating current. The error does not stop the inverter; instead the inverter tries to connect to the grid again. Sporadic repetition of the error is a sign of large grid distortions or sudden changes in sunlight; whereas systematic repetition of the error warning will be a sign of an inverter fault
- E024Error codeError inside the inverter
- E025Error codeBefore connecting to the grid, the inverter measures the insulation resistance of the PV array compared to ground. If the insulation resistance measured by the inverter is less than 1 MOhm, the inverter does not connect to the grid and shows the “Riso Low” error. The causes may be: - Damaged PV module(s). - Junction box(es) not properly sealed, allowing water intrusion; - Loose connections between modules allowing humidity leakage; - Poor quality cable junctions; - Presence of unsuitable (trigger voltage lower than the characteristics of the PV array strings) or damaged overvoltage surge arresters outside the inverter in the DC section. - Presence of humidity inside the photovoltaic module
- E026Error codeWrong measurement of the reference voltage inside the equipment
- E027Error codeError in the internal measurement of the grid voltage (imposed by regulations) to have a measurement redundancy (2 measurements on the same parameter carried out by two different circuits)
- E028Error codeError in the internal measurement of the grid frequency (imposed by regulations) to have a measurement redundancy (two measurements on the same parameter carried out by two different circuits)
- E029Error codeError in the internal measurement of the insulation resistance of the PV array compared to ground (imposed by regulations) to have a measurement redundancy (two measurements on the same parameter carried out by two different circuits)
- E030Error codeHigh leakage current (DC side): Error in the internal measurement (made when the in verter is grid connected) of the leakage current of the DC side (PV generator) compared to ground (set by law) in order to have a redundant measurement (2 measu rements on the same parameter made by two different circuits)
- E031Error codeOutput relay damaged: Measurement of internal voltage on heads of the output relay outside of range. There is too great a difference in voltage between the input and output of the grid connec tion relay
- E032Error codeImbalanced output currents: Measurement of the unbalance in the output voltage (made across the three phases) outside of range (only in triphase models)
- E033Error codeLow ambient temperature: Temperature outside the inverter below -25°C
- E034Error code“IGBT” circuitry not ready: Error inside the inverter
- E036Error codeAverage of the measurements of grid voltage out side of range: The average value of the grid voltage (sampled every 10 minutes) does not fall within the permitted ranges. The grid voltage in the point connected to the inverter is too high. This may be caused by too high a grid impedance. In the fni al stage of the timeout, the inverter limits the po wer to check whether the grid voltage has stabilised into regular parameters. If this does not happen, the inverter disconnects from the grid
- E037Error codeLow value of the insulation resistance (only with the “Amorphous” mode activated): This error can occur only should the “Amorphous” mode be on. This function is on only in inverters equipped with a grounding kit and serves to monitor the voltage at the heads of the grounding resistance. The error occurs when the voltage at the heads of the resistance con nected between ground and the pole of the photovoltaic generator exceeds 30V for more than 30 minutes or 120V for more than one second
- E046Error codeError during the automatic check of the string volta ges (only in models with the “fuse-control” board): In some inverter models it is possible to carry out the check test of the polarity of the strings connected to the input (e.g.:TRIO-20.0/27.6kW). This error signal occurs when, during the test stage, an inverted string is recorded
- E049Error codeError in the “AC feed-forward” circuit: Error inside the inverter
- E050Error codeAn electrical arc has been detected on DC cables. This error latches the inverter in a disconnected state
- E051Error codeInternal memory error
- E053Error codeSelf-Test performed by AFD board failed. The board will try another self-test after user turns inverter off and on
- E054Error codeWiring box is not communicating with the inverter
- E055Error codeAFD confgi uration is incorrect
