UpvMax Overvoltage at DC input.
Immediately disconnect the DC input of the Windy Boy.
Otherwise the Windy Boy could be severely damaged!
Check the configuration of your system and measure the DC voltage
before reconnecting the Windy Boy to the DC voltage.
Watchdog Error message in the program code flow monitoring.
Zac-Bfr /
Zac-Srr The grid impedance is no longer within 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. The impedance is calculated from the grid
impedance and the impedance of the Windy Boy's grid connection
cable (AC cable).
Check the grid impedance and the grid connection at the Windy
Boy. Use a cable with an adequate cross-section (= low
impedance), observe the advice to this effect in the installation
manual. If the grid impedance is still too high, ask the grid operator
if the grid characteristics at the feed-in point can be altered.
