My i2000 made the same annoying noise all hte time. Sanded the blades with a fine sandpaper and primed them. Next was a layer of paint with.. sand.. yeah literal sand mixed in. Like birdsand grade. Makes the surface a little rough, but it dead silent now. Cant hear it at 25 meters ant 10ms wind. You notice it when the wind turns a bit and the turbine is tracking a bit roughly.
@@Deiphobuzz I've never heard of that idea thanks for sharing. I must admit it's quieter now having tuned the MPPT several times since then to effectively slow the rotor down . I noticed quickly the most whistling occurs following a gust then the rotor is freewheeling relative to the wind speed passing over the blades or when the MPPT was disconnected completely leaving the generator with no load so i deduced keeping the rotor loaded nicely helps the aerodynamics of the blades and avoids lots of the whistle . It still occurs to some extent but the house is 170 meters away so you never hear it there now even while stood outside and in any weather conditions but when it was first installed and the MPPT was poorly tuned you could hear it through the closed windows in even the slightest breeze!
sure seems to catch the wind very well, can you show us the meter?
Yep, that's coming soon .

This is a professional wind generator I made myself, it's not as beautiful as this one.
