400w Vertikale Windturbine Windkraftanlage Flanschdesign 12v Schiffseinsatz

Look great, but hardly produce electricity. Don’t buy it.

I was able to install them finally found some more mounting hardware to put it up on a pole took me about two weeks to find what I needed item would be better if it was sold with the amount that would hook up onto a pole which wasn’t included factory mounting hardware runs about $100 was able to install it with a pole and some mounting hardware for about 25.00

Instructions don't explain which way the blades should be installed.At the time of purchase, the price was great. Might be cheaper or more expensive now, not sure. But I got it for the price back then.

I’ve been powering my nav/com board for the past two years with this turbine and 8 small solar panels (GPS, VHF, depth sounder, front-camera monitor, horn, recharging station) without a single problem. This thing has spun so fast in a storm that it looked like a pink globe and it produces a decent current even in slight breezes. Love it!

Good product!! Good quality and works well. You well need to modify it a bit but overall, happy with the product.

No hace ruido y trabaja muy bien para mi sistema off grio

Exceeded my expectations,would like to have as a package with pole.

Came very quickly, well packaged. Looks great. It was a Christmas gift so we won't be able to get it up until spring but everything appears to be just as advertised! Can't wait to put it to work!!

I bought one of these on a whim to supplement my off-grid solar array with a bit of help at night. Unit appeared high quality. Powder coated motor, high quality hardware - -washers AND Lockwashers - (almost unheard of these days). Drilling was to spec and pieces went together easilly. I mounted it on a 1.25 inch black pipe with a threaded flange from an orange home chain store. The drilled holes almost match the 4 pattern flange holes. (A dremel tool helps.) Major Kudos to a Chinese company for putting out glossy photographic instructions with a professional quality English translatio!. (Much better than some I've seen.!) As noted, output can be inconsistent in gusty winds, and you really need to be honest with yourself about how much wind is blowing at the mounting location vs. the treetops. Also, as noted, the controller will track wind gusts with lag. This will work best in a location with steady winds. I don't get as much as I hoped for, but on very windy nights, my overnight battery voltage drop is noticably less than it was before I installed it. Lastly, laws of physics say the wind pressure (I.e. power) goes up with the square of the wind speed more or less, so although it will generate power at lower wind speeds, don't expect much until you get steadily above 20mph or so.

I like this product’s simplicity and clean design. It works like a charm! I bought it to add on to my solar power system and it’s been great Provided the pricce don’t go up, I plan to purchase one or two more.
