SMA Solar Technology AG Troubleshooting 9 Troubleshooting If the inverter displays other blink codes or error messages than those described below, contact the SMA Service Line. You will also find a description of display messages during operation, status messages and measurement channels in the user manual provided.
SMA Solar Technology AG Troubleshooting 9.2 Error Messages When a fault occurs, the inverter generates a message which depends on the operating mode and the type of the fault detected. Message !PV-Overvoltage! Description and corrective measure Overvoltage at DC input !DISCONNECT DC! Overvoltage can destroy the inverter. Corrective measures Disconnect the inverter from the mains immediately. 1. Disconnect the miniature circuit-breaker. 2.
SMA Solar Technology AG Troubleshooting Message EEPROM Description and corrective measure Transition fault while data is being written or read from EEPROM. The data is not relevant for safe operation. EEPROM dBh This fault 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 Service Line.
SMA Solar Technology AG Message Earthfault Troubleshooting Description and corrective measure The electrical insulation between the PV plant and earth is defective. The resistance between the DC plus and/or DC minus connection and earth is outside the defined limit range. Corrective measures • Check the insulation of the PV plant. ROM Shutdown Vac-Bfr Vac-Srr • Check the installation for earth faults as described in Section 9.3.1 "Checking the PV Array for Earth Faults" (page 57).
SMA Solar Technology AG Troubleshooting Message VpvMax Description and corrective measure Overvoltage at DC input. The inverter may be damaged. Corrective measures Vpv-Max Immediately disconnect the inverter from the mains. 1. Disconnect the miniature circuit-breaker. 2. If an external DC switch-disconnector is available, disconnect it. 3. If an Electronic Solar Switch is installed, remove it. 4. Remove all DC connectors. 5.
SMA Solar Technology AG Troubleshooting 9.3.1 Checking the PV Array for Earth Faults 1. Disconnect the inverter from both the DC and AC sides as described in Section 7.2 "Opening the Inverter" (page 45). DANGER! Risk of lethal electric shock • Only touch the cables of the PV array on their insulation. • Do not connect strings with earth faults to the inverter. NOTICE! Excessive voltages can destroy the measuring device. • Only use measuring devices with a DC input voltage range up to at least 1 000 V. 2.
SMA Solar Technology AG Troubleshooting Result ☑ You have found an earth fault. Measure • The installer of the PV array must remedy the earth fault in the affected string. You can determine the location of the earth fault as described below. • Do not reconnect the faulty string. ☑ You have found no earth fault. • Commission the inverter as described in Section 6.1 "Commissioning the Inverter" (page 38). It is likely that one of the thermally monitored varistors is defective.
SMA Solar Technology AG Troubleshooting 9.3.2 Checking the Function of the Varistors Varistors are wear parts. Their functional efficiency diminishes with age or repeated strain as a result of overvoltage. It is therefore possible that one of the thermally monitored varistors has lost its protective function, and thus the red LED is lit. Position of varistors You can determine the position of the varistors using the illustration below.
SMA Solar Technology AG Troubleshooting Result ☑ There is no conducting connection. Measure The respective varistor is defective and must be replaced. Varistor failure is generally due to influences which affect all varistors similarly (temperature, age, induced overvoltage). SMA Solar Technology AG recommends that you replace both varistors. The varistors are specially manufactured for use in the inverter and are not commercially available.
SMA Solar Technology AG Decommissioning 10 Decommissioning 10.1 Unmounting the Inverter CAUTION!
