10.8 Operating states of SkyWind NG
a) Open circuit (
DANGER!
)
If the turbine would not be connected to a charge controller/grid inverter and the storm control
system it would rotate without load.
This state would be extremely dangerous as the rpm will
increase ever further until the rotor blades disintegrate!
Do not mount rotor blades to the
nacelle if the electric installation is not finished and working properly. In case of an emergency
use the OFF switch of the the turbine. Never remove cables or contacts or even touch the
cables once installation is finished.
b) Normal operation
If the generator is connected to the grid inverter or charge controller it will generate power.
The rpm is regulated by the controller. The turbine should be rather quiet since all energy gene-
rated is immediatly converted into electricity and discharged through the cables.
c) Brake/Shut
-
off
If the turbines main switch is set to OFF or if the storm control detects too high winds the turbi-
ne will be shut
-
off. The rotor blades will almost stop rotating within seconds and the turbine
will stop generating power immediately. The generator is heating up during this process. The
turbine can continue working after one hour, either because the storm control reactivates the
turbine automatically or because the main switch is set to ON. The main switch may never be
used more than once per hour.
After reactivation the turbine will resume operation in normal operation.
A turbine operating without load might not only disintegrate, the in-
creased loads on tower and structure might also damage or destroy
your tower and foundation.
A SkyWind NG turbine must work smoothly in normal operation mo-
de. Should you find that the turbine vibrating or not generating power
check all aspects of the system.
Install the AC main switch as shown in the wiring diagrams. Any fuse
or RCCB must be installed outside of the system (before the main
switch)
NEVER AND NOT FOR A SINGLE SECOND IS IT ALLOWED TO OPERATE
THE TURBINE WITHOUT LOAD IN OPEN CIRCUIT MODE!
