Troubleshooting SMA Solar Technology AG Message Derating dZac-Bfr dZac-Srr EEPROM EEPROM dBh EeRestore Fac-Bfr Fac-Srr FacFast Description and corrective measure The "Derating" operating mode is a normal operating mode that may occur occasionally and can have several causes. Once the inverter enters the "Derating" mode, it will display the "Derating" warning until the next total shutdown of the device (at the end of the day). Corrective measures • Check heat dissipation, as described in section 8.1 ”Checking Heat Dissipation” (page 41). Sudden changes in grid impedance exceed the permissible range ("Bfr" or "Srr" are internal messages of no relevance for the user). For safety reasons, the inverter disconnects itself from the grid. Corrective measures Check the grid impedance and observe how often major deviations occur. • If repeated frequency variations occur and this is causing "dZac-Bfr" or "dZac-Srr" errors, ask the utility operator if it would agree to modify the operating parameter (dZac-Max). • Discuss changing the operating parameter with the SMA Serviceline. Transition disturbance during reading or writing of EEPROM data. The data is not relevant for safe operation. • The disturbance has no effect on the performance of the inverter. EEPROM data is defective, the device has switched off because the loss of data has disabled important functions of the inverter. Corrective measures • Contact the SMA Serviceline. One of the duplicate data sets in the EEPROM is defective and has been reconstructed without loss of data. • The error message only serves to inform you and has no effect on the performance of the inverter. The grid frequency is no longer within the permissible range ("Bfr" or "Srr" is an internal message of no relevance for the user). For safety reasons, the inverter disconnects itself from the grid. Corrective measures • If the grid frequency is within the tolerance range, yet "Fac-Bfr", "Fac-Srr" or "FacFast" faults are still being displayed, contact the SMA Serviceline. 48 SB33_38-IEN100540 Installation Guide
SMA Solar Technology AG Troubleshooting Message Imax K1-Close K1-Open MSD-Fac MSD-Vac NUW-Timeout MSD-Timeout Offset Riso ROM Description and corrective measure Overcurrent on the AC side. This fault code is displayed if the current in the AC grid is larger than specified. Corrective measures • Check the system design and grid conditions. Fault during relay test. Corrective measures • Contact the SMA Serviceline if this problem occurs frequently or several times in succession. Internal measurement comparison fault or hardware defect. Corrective measures • Contact the SMA Serviceline if this disturbance occurs frequently. Internal measurement comparison fault or hardware defect. Corrective measures • Contact the SMA Serviceline if this disturbance occurs frequently. Internal measurement comparison fault or hardware defect. Corrective measures • Contact the SMA Serviceline if this disturbance occurs frequently. Internal measurement comparison fault or hardware defect. Corrective measures • Contact the SMA Serviceline if this disturbance occurs frequently. The "Derating" operating condition is a normal operating condition that occurs prior to grid monitoring. If "offset" is displayed as an error, then there is a disturbance in the data logging. Corrective measures • Contact the SMA Serviceline if this disturbance occurs frequently. The electrical insulation between the PV system and ground is faulty. The resistance between the DC plus and/or DC minus connection and ground is outside the defined limit range. Corrective measures • Check the insulation of the system. • Check the system for ground faults as described in section 9.3.1 ”Checking the PV Generator for a Ground Fault” (page 52). The inverter's firmware is faulty. Corrective measures • Contact the SMA Serviceline if this disturbance occurs frequently. Installation Guide SB33_38-IEN100540 49
