Termtech Sussex Installation

Postby Conundrum » Sun Feb 17, 2013 9:47 pm

Sussex installation of a 500W wind turbine. This turbine is using a specialized 12V controller instead of our usual 24V controller.

It doesn't look like that tower is very straight. Does it work if it isn't level?

Thats an optical illusion. It was actually level but the hill makes it look like its off.

With most turbines it is very important to keep them level because of the way the tail regulates the turbine speed. In high winds, the nacelle is forced out of the prevailing wind by an uneven aerodynamic force on the blades. The tail stays in to the wind and the 'head' turns to slow the blades. The danger of having a tower that isn't level is that when the nacelle is turned out of the wind due to a high wind speed, the tail relies partially on gravity to return to position. If the tower isn't level it can remain in a turned condition.

Part of the suggested annual maintenance is to go to the base of the tower and make sure the tower is still level.

I'm just curious:
Why was a different controller used?
What was special about it?

It is a hybrid controller that can toggle between 12 and 24v output. It was used because the system built previous was 12v, and it was easier to use a specialized controller than to convert the remainder of the system.
