Wind generator does not perform as described

By KeyWestCaptain
from Key West, FL
"As a 12 year live aboard boater, I depend on wind to compliment our solar array. After 8 years our previous wind generator blew its internal circuit board. I like the idea of this unit having the rectifier/ controller inside the boat. The problem is that the blades on this N power generator are so poorly balanced that it vibrates terribly. today we have 25 mph of wind. I once saw it produce 200 watts for a moment, but then the vibration takes over and it produces about 25 watts. the sound when it is vibrating is deafening. Right out of the box the bearings did not seem smooth. I guess I will install a quality bearing, and use the blades from our previous generator. The blades look like the have the same mounting holes. This unit has been producing up to 100 watts if the wind does not get over 15 mph. So the bottom line is: today the wind is blowing, and I have to turn the unit off because of vibration. The blades supplied with the Npower do not seem to be the same shape as the ones shown in the picture."

Don't bother

"I bought the wind turbine to compliment my solar array. My house is on top of a 200 ft hill and I have it on top of the house. Unless you have a constant 15 to 20 mile per hr wind the turbine will not even spin. I should have increased my solar array instead of wasting money on this."

"I bought the n power 400 watt turbine.I have it 37ft in the air.it spins easly,but it doesnt start spining at 8mph its more like 12mph to get the light on the control panel to come on.I have a 800 amp hour battery bank with solar panels ,the wind turbine does produce some power but you really need solar too.When i get 15 mph wind its making power,when its 20 or above you can watch the volt meter increase .It looks cool and works great addition to my solar"
