What's the difference between our turbines and the other inexpensive turbines ?
Realistic, accurate output ratings. We could pump up our output ratings like many others but we don't. Our ratings are real world ratings, not something with no basis in reality. Be careful of cheap turbines with high output ratings. They are WAY overrated. Cheap turbines with high output ratings are like honest politicians, they don't exist.
Welded Steel frame. We build our turbines to last. We don't use plastic for frames because it doesn't last.
Steel hub. We build our hubs to last. We don't use plastic as a hub material because it doesn't last.
Blades made on CNC milling machine by a machinist. Our blades are milled to a consistent airfoil to make them balance better, run smoother and produce more torque. Most, if not all of the blades seen on ebay, are not consistent, not balanced and will eventually destroy the bearings in your generator.
Professionally engineered and manufactured. After 21 years and 141,000 micro wind turbines sold worldwide, we know what we're doing. We have 42 dealers worldwide and produce about 100 turbines per week for them.
Be careful what you buy. If it sounds too good to be true, it is.
We use 100% recycled packing material.
Customs fees, taxes, duties are the buyers responsibility.
This is a new 3-blade 50 watt low speed wind turbine generator model 2, built entirely within the USA. It was designed to produce a maximum of 34vdc and 2 amps in perfect test conditions. You may or may not see the same results in the real world due to variations in installation, wind and many other variables.
Output is computed using open voltage times direct short amps. This turbine is a great compliment to your solar panels and in decent winds will trickle charge your battery. Cut in speed is around 15 mph.
This is a medium speed wind turbine. Excessive wind can damage this turbine.
The turbine is very compact, measuring about 20" long and utilizes 3 blades each being 12" long.
The prop hub is made of .076" steel.
The arbor that connects the hub to the motor shaft is machined from 6061 T-6 aluminum and has 2 allen set screws to keep it securely fastened to the shaft.
The turbine weighs about 3 pounds.
A suitable pole with a 1" I.D. is needed to mount the turbine.
Your wiring (14 gauge for runs up to 50 feet) should be run from your battery, up through the pole and then through the turbine downtube on to the top of the turbine frame where it is then connected to the wires running from the turbine motor.
If you leave 24" of slack in the wire at the bottom of the pole wire twisting is normally not a problem.
A blocking diode is already installed so that the turbine will not discharge your battery when the wind is not blowing.
The turbine frame is made from 3/4" steel square tubing and is capped on each end. The downtube is welded to the bottom of the frame and is made from 7/8" O.D. round steel tubing. The entire frame is then painted black.
The tail fin is made of fiberglass reinforced plastic. The motor is securely fastened to the frame and will not come loose.
The motor cover is purely cosmetic and is made of black, ribbed plastic.
The propeller blades are made from PVC plastic pipe and may or may not have some scuff marks on them from shipping.
Replacement blade sets as well as any other parts are available if you ever need one.
The turbine comes 95% assembled. All you have to do is bolt the tail fin to the main beam, bolt the blades to the prop hub and install the hub onto the arbor. We reccomend the use of Blue Locktite threadlocker.
This turbine can be used to charge 12 volt batteries, run a string of LED lights and even works with some grid-tie inverters. More wind will make your battery charge faster.
We have sold several thousand of these turbines over the years and they have been used sucessfully by boaters, farmers, ranchers, RVers, campers, hunters and science classes all over the world.
We can ship 2 of these turbines in the same box at no extra cost to you.
We ship worldwide and we ship quickly. A USPS tracking number is automatically sent to your Paypal email address when we ship.
The turbine is professionally packaged to aviod damage during transit. We use recycled packing material exclusively.
Each and every one of these turbines is tested for both function and output 3 times before boxing. The motor is tested when it is unboxed. It is tested again after the blocking diode is installed. The final test is done after the motor is installed onto the frame.
Every turbine leaves our facility functioning exactly as described.
Please remember that you are buying the least expensive micro wind turbine on the planet and adjust your expectations accordingly.
Any and all taxes, duties or import fees are the sole responsibility of the buyer.
We expect payment within 24 hrs of auctions end.
