10.2 Error Messages
If an error occurs, the Windy Boy generates a message, which is dependent on the
operating mode and the type of error detected.
Error Code
Description
!PV-
Overvoltage!
!DISCONNECT
DC !
Overvoltage at DC input.
Immediately disconnect the inverter from the PV generators!
Otherwise, the inverter may be damaged.
Check the configuration of your system and measure the DC voltage
before reconnecting the inverter to the DC voltage.
ACVtgRPro
The average grid voltage over 10 minutes is no longer within the
permissible range.
This can be due to either of the following reasons:
•
The grid voltage at the connection point is too high.
•
The grid impedance at the connection point is too high.
The inverter disconnects to allow compliance with the voltage
quality of the grid. Check the grid voltage at the Windy Boy's
connection point. If, due to the local grid conditions, the grid voltage
increases to 253 V or more, ask the grid operator whether the
voltage at the feed-in point can be adjusted, or whether they agree
to an alteration of the threshold value ACVtgRPro (operating
parameter: ACVtgRPro) for voltage quality monitoring. If the grid
voltage is continuously within the acceptable range, yet the
"ACVtgRPro" error is still displayed, contact the SMA hotline.
Bfr-Srr
Internal measurement comparison error or hardware defect.
Contact SMA if this error occurs frequently.
derating
Once the Windy Boy enters the "Derating" mode, it displays the
"derating" warning until the next time the device is switched off. If
this warning appears frequently, check the heat dissipation of your
device.
dFac-Bfr /
dFac-Srr
The changes in grid frequency are outside the permissible range
("Bfr" or "Srr" is an internal message which has no meaning for the
user).
The Windy Boy disconnects from the grid in order to avoid potential
damage or islanding. If possible, check the grid frequency and
observe how often major deviations occur. If repeated deviations
occur and this is causing "dFac-Bfr" or "dFac-Srr" errors, ask the grid
operator if they agree to a modification of the operating
parameters. Discuss the proposed parameters with the SMA hotline.
