14. Choosing A Suitable Tower
Choose a matching tower. The tower must at least:
1. Withstand a thrust force from the turbine of
750 N
2. The tower top must not deflect more than
1°
from the vertical under 50% load
3. The tower resonance frequencies must not be between
10
-
50 Hz
4. The tower top meter must have a diameter of
60 mm
5. The tower top must exceed the height of the surrounding trees, buildings etc.
A wall thinkness of at least 3 mm is recommended. Only steel towers should be used. Guy
wires may be used if needed.
Firmly tighten the two turbine securing screws (yellow markings). Make sure that both
screws are evenly tightened. The nacelle must be fixed in an absolutly parallel position
to the ground.
13. Finalizing The Electrical Installation
Check the whole electrical installation and write down your wiring diagram.
Document all settings of your storm control system and of your inverter by taking pic-
tures. Without photographic documentation your warranty is void.
As soon as the turbine is provided with sufficient wind speed the inverters will invert
power into the grid.
The inverters will work on standard 230V and 110V AC grids. The inverters are set up for
the SkyWind only and may not work with other turbines or solar panels.
