Error Codes | |||
Code | Code Type | Meaning | Solution |
Interferrence | Internal fault | SEE CODE 77 BELOW | |
DI MEAS | Installation problem | Indicates that the inverter has detected a leakage current that is too high (.90MA) or a suddeng change od mote than 30MA in the leakage current. This error message is usually cause by a problem with the installation of the grounding conductor in the AC side. | Installer to attend site |
!PV-Overvoltage! | Overvoltage DC | SEE CODES 34xx | Disconnect DC, check the manual and measure/check the pv-system |
Bfr-Srr | Error AC-side | Inverter isn't detecting any power from the electricity grid. This may be because no power is available from the grid or it may be that the power coming from the grid is not complying to the parameters set inside the inverter. | This error would normally occur during a grid failure, if you still have electricity connected to your property then check your AC isolator or circuit breaker. If both the Isolator and CB are 'on' and the problem persists ESD customers should submit a support ticket |
Fac-Bfr | Error AC-side | ||
Fac-Srr | Error AC-side | Power frequency not in range | This error would normally occur during a grid failure, if you still have electricity connected to your property then check your AC isolator or circuit breaker. If both the Isolator and CB are 'on' and the problem persists ESD customers should submit a support ticket |
FacFast | Error AC-side | ||
Imax/overcurrent | Overvoltage AC | overcurrent on the AC side. This message usually only appears in transformer inverters and is displayed if the electric current on the AC grid is higher than specified or if there are direct current components in the grid current | ESD customers should submit a support ticket |
K1- close/ K2-close | Internal fault | Disturbance of Grid Relays | If the messafe only appears very rarely (a maximum of once or twice a week) no further action has to be taken, In this case, the next step is to continue to monitor the device. I the distubrance occurs frequently, for safety reasons the inverter switches to the "Permanent Disable Mode" and the yellow LED is continuisly illuminated.If this occurs, inverter needs to be replaced with the warranty |
K1- Open/K-2-Open | |||
Riso | Installation problem | The Riso error message indicates that the inverter has discovered a ground fault in the PV Array or that the PV modules insutaltion resistance (R-Iso) is too low | ESD customers should submit a support ticket |
Vac- Bfr | Overvoltage DC | inverter isn't detecting any power from the electricity grid. This may be because no power is available from the grid or it may be that the power coming from the grid is not complying to the parameters set inside the inverter. | This error would normally occur during a grid failure, if you still have electricity connected to your property then check your AC isolator or circuit breaker. If both the Isolator and CB are 'on' and the problem persists ESD customers should submit a support ticket |
Vac-Srr | Overvoltage DC | ||
101-103 | Grid Error | The gird voltage or grid impedance at the connection point of the inverter is too high. The inverter has disconnected from the utility grid. | ESD customers should submit a support ticket |
202-205 | Grid Error | The utility grid has been disconnected, the AC is damaged or the grid voltage at the connection point of the inverter is too low. The inverter has disconnected from the utility grid | |
301 | Grid Error | The ten-minute average value of the grid voltage is no longer within the permissible range. the grid voltage of grid impedance at the connection point is too high. The inverter disconnects from the utility grid to maintain power quality. | |
302 | Grid Error | The inverter has reduced its power due to a too-high grid voltage to ensure grid stability. | |
401-404 | Grid Error | The inverter has disconnected from the utility grid. A stand-alone grid or a very large change in the power frequency was detected | |
501 | Grid Error | The power frequency is not within the permissible range. The inverter has disconnected from the utility grid. | |
601 | Grid Error | The inverter has detected an excessively high proportion of direct current in the grid current. | |
701 | Frequency out of range | Frequency not permitted > Check parameter - The power frequenct is not within the permissible range. The inverter has disconnected from the utility grid. | |
901 | No PE-Connection | The grounding conductor is not correctly connected. | |
1001 | L-N Swapped | The connection for L and N is swapped | |
1101 | Installation problem | A second Line conductor is connected to N | ESD customers should submit a support ticket |
1302 | installation problem | L or N not connected | ESD customers should submit a support ticket |
3301-3303 | Unstable | There is not enough power at the DC input of the inverter for stable operation. The Inverter cannot connect to the utility grid. | Customer: Ensure that the PV array is not covered by snow/debris or otherwise shaded |
3401-3402 | Overvoltage DC | Overvoltage at the DC input. This can destroy the inverter. This message is signalized additionally by rapid flashing of the LEDs. | ESD customers should submit a support ticket |
3501 | Insulation | The inverter has detected a ground fault in the PV array. | ESD customers should submit a support ticket |
3601 | Leaking Current | The inverter has detected a residual current due to temporart grounding of the PV array | Restart System |
3701 | residential Current | Overvoltage at the DC input. This can destroy the inverter. This message is signalized additionally by rapid flashing of the LEDs. | ESD customers should submit a support ticket |
380,138,023,805 | DC overcurrent | Overcurrent at the DC input. The inverter briefly interrupts feed-in operation. | ESD customers should submit a support ticket |
6001-6438 | self diagnosis | Lost internet connection - can occure when internet is down or passwords changed. | Restart system/check internect connection and passwords |
64 | self diagnosis | ||
64xx(any 4-digits starting with 64) | self diagnosis | Interferance- no yield loss here | Full system restart |
6501-6502,6509 | self diagnosis | Inverter has switched off due to high temperature | Customer to Clean the cooling fins on the rear of the enclosure and the air ducts on the top using a soft brush. Ensure that the inverter has sufficient ventilation. Ensure that the ambient temperature does not exveed +40deg. Ensure that the inverter is not exposed to direct solar irradiation. |
6602-6604 | self diagnosis | Overload | call SMA with the ff info from customer. Device type and serial number of the inverter, How long has the error been present for now? Is it sporadic or continuous?, Has restart User-added image been performed yet?, Are there error messages or is the device beeping? |
6801-6802 | self diagnosis | Input A Defective | |
6901-6902 | self diagnosis | Input B Defective | |
7401/74 | Varistor problem | at least one of the inverter's thermally monitored varistors is defective | Varistors to be checked/replaced. SMA requires an elecrician to check the varistors first and then if required, warranty claim |
7701 | self-diagnosis | shifter neutral point/ star point. This can be caused by larger consumers on the grid, for example air conditioners, pumps, large motors and lifts or by faulty installation. | ESD customers should submit a support ticket |
