3.3.4 Description of the operational status
No (or low) input voltage
The Windy Boy 5000 / 6000 is in
Standby mode. This situation occurs
when the input performance at the
Windy Boy 5000 / 6000 is too low for
feeding the mains supply (DC input
voltage < approx. 80 V) and for
satisfying the on-board power
requirements.
Initialization
The on-board computer of the Windy
Boy 5000 / 6000 is presently in the
initialization process. The DC input
voltage of the Windy Boy 5000 / 6000
lies between approx. 80 V and approx.
120 V. The power is adequate for the on-
board power requirements but
insufficient for mains supply feed-in or for
data transmission.
Working mode
The Windy Boy 5000 / 6000 has
successfully passed the measurement
electronics and SMA grid guard self-tests
and has begun feed-in operation.
The Windy Boy 5000 / 6000 is working
normally and is feeding electricity into
the mains supply. It is converting the DC
voltage from the wind turbine according
to the V/I characteristic curve defined by
