What does 'K1-Close K1-Open' error mean on SMA WINDY BOY 3300?
If the SMA Inverter displays 'K1-Close K1-Open' often or several times in succession, contact the SMA Serviceline, as it indicates a fault during relay test.
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 'Bfr-Srr' error on SMA Inverter indicate?
If the SMA Inverter displays 'Bfr-Srr' often, contact the SMA Serviceline, as it indicates an internal measurement comparison fault or hardware defect.
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.
Why does my SMA Inverter show 'Fac-Bfr Fac-Srr FacFast' errors?
If your SMA Inverter is showing the 'Fac-Bfr Fac-Srr FacFast' error, the grid frequency is no longer within the permissible range. If the grid frequency is within the tolerance range, yet the errors are being displayed often, contact the SMA Serviceline.
What does 'dZac-Bfr dZac-Srr' mean on my SMA Inverter?
If the SMA Inverter displays 'dZac-Bfr dZac-Srr', it means sudden changes in grid impedance exceed the permissible range. Check the grid impedance and observe how often major deviations occur. If repeated frequency variations occur and this is causing the errors, ask the utility operator if it would agree to modify the operating parameters (dZac-Max). Discuss changing the operating parameter with the SMA Serviceline.
Why is my SMA WINDY BOY 3300 showing 'Trafo-Temp-W' error?
If the SMA Inverter displays 'Trafo-Temp-W', it means the transformer has reached an unacceptably high temperature. Check the heat dissipation.
What causes 'Trafo-Temp-F' error on my SMA WINDY BOY 3300?
If the SMA Inverter displays 'Trafo-Temp-F', the temperatures in the transformer have exceeded the acceptable limit. If this problem recurs, check the heat dissipation of the inverter, as described in section 8.1.
How to fix 'Zac-Bfr' or 'Zac-Srr' error on SMA WINDY BOY 3300?
If your SMA Inverter displays 'Zac-Bfr' or 'Zac-Srr', the grid impedance has left the permissible range. Check the grid impedance and grid connection on the inverter. Use an AC cable with an adequate cross-sectional area (low impedance). If required, check and re-tighten the screws on the AC terminals. If this fault recurs, 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.
