VEVOR 800W Wind Turbine Generator Kit, 12V 3-Blade Power Generator With MPPT Controller, Adjustable Windward Direction & 2.5m/s Start Speed, for Home, Farm, RVs, Boats

Unit did have a little noise when new out of the box. I have had it running for weeks now including 60 mph winds from a storm. It is breaking in nicely and makes good power. Only issue is with the controller that comes with it. Wants to auto break too often in moderate winds. Just get a better more versatile controller to get better usable output. Bearing sounds are a non issue for me after breaking in the unit.

This was advertised for use on boats or RVs, but it's too big to mount on anything smaller than a yacht, and by the time you figure that out it's too late to return it. In general I like Vevor's copies of common goods, and find them to be the best Chinese copies I've used, but they're still Chinese copies at the end of the day. This product fails miserably and is unusable unless maybe you can mount it the 10 METERS(!!!) ABOVE ANY NEARBY OBJECTS AS IT SUGGESTS IN THE MANUAL!That means it needs a dedicated steel tower column of at least 8" driven 5M deep into the ground or 2M with 500 pounds of reinforced concrete base with at least 8 wire stays!

Well built

The media could not be loaded. I purchased three (3) of these Vevor 800 watt wind turbines - One of the three was purchased from Amazon. All three had the same problems - The most critical issue is defective internal bearings - Please watch the video to hear the knocking bearing - I kept ordering this turbine hoping to finally get a good one but after three I stopped trying - I own many different types and sizes of wind turbines and have never had bad bearings before - Until this problem is resolved I cannot recommend this turbine
