This is a 10-blade, 250 watt low speed wind turbine generator built entirely within the USA. Output is computed using open voltage times direct short amps measured at the turbine in perfect test conditions. It was designed to produce a maximum of 30 vdc and 8.5 amps in perfect test conditions. You may or may not ever see this output in the real world due to variations in installations, winds and many other factors that affect turbine output. This turbine normally starts turning in 8-10 mph winds after it has been run-in. It may require a bit more wind when it is first installed. 

Since this is a low speed turbine I do not reccomend running it in winds much over 25 mph. Excessive wind can damage the generator.

The turbine is very compact, measuring about 25" long and utilizes 10 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 6 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 large 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 successfully by boaters, farmers, ranchers, RVers, campers, hunters and science classes all over the world.

We ship the turbine in a USPS Priority Mail large flat rate box in order to get YOU the least expensive shipping cost that is possible. We can ship 3 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 avoid 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.
