Insulation fault
The Windy Boy 5000 / 6000 indicates a
ground fault by illuminating the red LED.
Defective varistor
At least one of the two thermally
monitored varistors on the DC input side
of the device has become highly resistive
and thus no longer functions correctly.
Constant operational limiting
This message is displayed if a fault
develops in the grid monitoring and/or
the independent disconnection device
(SMA grid guard). The Windy Boy 5000
/ 6000 has detected a fault in the SMA
grid guard during an internal test and
has disabled the mains supply feed-in.
This usually indicates a fault that cannot
be corrected on site. Please consult the
manufacturer (chapter 12 "Contact”
(page 67)) and discuss further action to
solve the problem with them.
Consult trained electrical personnel to correct the fault using the
"Installation manual".
