6.4 General setting example
Please note that the following example only represents a starting point for operating
with a wind generator.
• is set to the lowest possible value:
This achieves an early switch-on of the Windy Boy 5000 / 6000.
• is set to the same value of :
This achieves an early mains supply feed-in. If the wind turbine does not properly
start, or the Windy Boy frequently switches on and off, it is recommended that you
increase in (e.g.) 10 V steps.
• is initially set to approx. 10 % below the maximum MPP voltage
of the Windy Boy 5000 / 6000:
In this case the slope of the ramp function is relatively flat. The maximum output
power is only reached with a relatively high DC input voltage, which avoids
"braking" of the wind generator through excessive power consumption. This
setting is especially suitable in locations with little or weak wind. Once the
properties of the wind generator are known, then the reduction of the
parameter may be necessary, in order to extract the maximum
power from the wind generator even at low DC input voltages (low wind speeds).
The ramp function will then be steeper.
• is set to the maximum value:
Here, the Windy Boy remains connected to the mains supply, even at low DC
input voltage levels, and "waits" for the next gust of wind. This delays an early
switch-off of the Windy Boy.
• is set to the minimum value:
This achieves a reduction of the switch-on time (please observe the regulations of
the energy supplier responsible).
Contact the manufacturer of your wind generator for the typical properties of
your generator (voltage/power characteristic).
Only change the operating parameters when you know exactly what you are
doing!
