What causes Trafo-Temp-F error on SMA WINDY BOY 3300 Inverter?
The Trafo-Temp-F error on your SMA Inverter means that temperatures in the transformer have exceeded the permissible limit. If this problem recurs, check the heat dissipation of the inverter, as described in Section 8.2.
What should I do if my SMA Inverter displays 'Vpv-Max' error?
If your SMA Inverter is showing 'Vpv-Max', it indicates overvoltage at the DC input. Immediately disconnect the small wind turbine system from the inverter. Turn off the line circuit breaker, stop the small wind turbine system, and disconnect all DC connectors. Check the DC voltage: if it exceeds the maximum input voltage, check the system design. If it's under the limit, reconnect the system as described in section 5.5.4. If the message persists, disconnect the inverter again and contact SMA Serviceline.
Why does my SMA WINDY BOY 3300 show 'ACVtgRPro' error?
If the SMA Inverter displays 'ACVtgRPro', it means the grid voltage at the connection point is too high. Check the grid voltage at the inverter's connection point. If the grid voltage is 253 V or more due to local grid conditions, ask the utility operator to adjust the voltage at the feed-in point or to agree to an alteration of the limit value 'ACVtgRPro' for voltage quality monitoring. If the grid voltage is continually within the acceptable range and this error is still displayed, contact the SMA Serviceline.
What does it mean when my SMA WINDY BOY 3300 Inverter shows 'Vac-Bfr' or 'Vac-Srr'?
If your SMA Inverter displays 'Vac-Bfr' or 'Vac-Srr', the grid voltage is no longer within the permissible range. Check the grid current and grid connection on the inverter. If the grid voltage is outside the acceptable range due to local grid conditions, ask the utility provider if the voltage can be adjusted or if it would agree to changes in the monitored operational limits (Vac-Min and Vac-Max). If the grid voltage is within the tolerable range, yet the errors persist, contact the SMA Serviceline.
What should I do if my SMA WINDY BOY 3300 Inverter shows Trafo-Temp-W?
If your SMA Inverter shows the Trafo-Temp-W error, it indicates that the transformer has reached an unacceptably high temperature. Check the heat dissipation as described in Section 8.2.
What to do if I see a warning/disturbance on my SMA WINDY BOY 3300 Inverter?
This message appears for safety reasons and ensures that the SMA Inverter does not connect to the electricity grid. Please inform your installer.
What does 'Watchdog Watchdog Srr' error mean on SMA Inverter?
If the SMA Inverter displays 'Watchdog Watchdog Srr' often, contact the SMA Serviceline, as it indicates an internal disturbance during program operation.
What to do if SMA Inverter shows Vac-Bfr or Vac-Srr errors?
If your SMA Inverter displays "Vac-Bfr" or "Vac-Srr" faults, it indicates the line voltage is outside the permissible range. You should check the line voltage and grid connection on the inverter. If the voltage is outside the correct range due to grid conditions, contact your network operator to see if adjustments can be made. If the voltage is within range but the errors persist, contact the SMA Service Line.
What to do if my SMA WINDY BOY 3300 Inverter displays 'EEPROM dBh' error?
If the SMA Inverter displays 'EEPROM dBh', it means the EEPROM data is defective. Contact the SMA Serviceline.
What does 'Riso' error mean on my SMA WINDY BOY 3300 Inverter?
If the SMA Inverter displays 'Riso', the electrical insulation between the small wind turbine system and ground is faulty. Check the system insulation and check the system for ground faults as described in section 9.3.1.
