VEVOR 500W Wind Turbine Generator, 12V Wind Turbine Kit, 5-Blade Wind Power Generator with MPPT Controller, Adjustable Windward Direction & 2.5m/s Start Wind Speed, Suitable for Home, Farm, RVs, Boats

We live in Iowa where there is a lot of wind. Added this to our garden solar array to run some lights and irrigation controller. Works well and does what it claims. I have 2 complaints. First complaint is mounting. They provide a collar that goes on the top of "a pipe." Unfortunately, that pipe isn't something you can just order. Nobody provides it and the dimensions are not clear. Finally found the right diameter at Lowe's in the electrical section after browsing several with collar in hand. I believe it was a 1.25" threaded steel pipe. $70 for 10 feet. They put 2 screw holes in the upper part of the collar to attach the turbine, but didn't put any in the bottom half to secure it to the pipe. They expect you to weld it on. Two threaded holes on the bottom would have been very handy and wouldn't require a weld joint. So far, we're getting lucky with it just sitting on the pipe - hasn't blown off yet in 30 mph gusts. My second complaint is the lack of information about the 3 wires that come out of it. Turbines are AC power, so they have 3 wires. You'd think there would be a Load, Neutral and Ground, but it doesn't seem to matter - it works no matter how they are connected.

good quality works well good value for the money.

Takes a consistent breeze to get it going. Very quiet.

After installing unit I had trouble with the controller drawing 10 amps off the batteries and not charging. I contacted there tech support, opened a ticket and all I got was a repeat of the installation manual that has nothing to do with the problem. After all the time installing you can’t really send it back. I just want it to work!!!

estoy muy satisfecha: es un equipo confiable, ecológico y que realmente aporta a la autosuficiencia energética. Lo recomendaría a cualquiera que busque aprovechar la energía del viento para su hogar o proyecto. Lo que más me ha gustado es que aprovecha incluso vientos moderados para generar electricidad, lo que lo hace muy útil en días nublados en los que los paneles solares no producen lo suficiente. Su construcción se ve sólida, con materiales resistentes a la intemperie, y hasta ahora no he tenido problemas de corrosión ni de fallos en las aspas.

Does not output anywhere near 500watts even at 50mph winds in a coastal region.

Great for off the grid camping. Saved me on those overcast days.

It looks good, easy to install. The problem is I can’t get the blades turning in a 15 mph wind, strong enough to shake the pole. It would spin in a gust of stronger wind but stop when it died down. Larger longer blades needed.
