| Description |
| This is a 30 watt high speed wind turbine generator built entirely within the USA. It was designed to produce 14-15 volts DC and .75-1.0 amps in 15-16 mph winds and it's output increases greatly as windspeed increases. I have seen these turbines produce 60+ watts in 60 mph winds.
This turbine will not function in low winds. Check your available winds before you buy any turbine.
The turbine is very compact, measuring about 20" long and utilizing a 2-blade 14" propeller. It weighs about 3 pounds. The turbine is very quiet even though it easily turns over 1000 rpm in 15-16 mph winds (verified with an optical tachometer).
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 (the motor is sealed) and is made of black, ribbed plastic.
The propeller has 2 blades and is 14" in diameter. It is made of plastic (prop color may be black or orange). Replacements are available for $6.00 each if you ever need one.
The turbine comes 99% assembled. All you have to do is bolt the tail fin to the main beam and press the prop onto the motor shaft.
This turbine can be used to charge 12 volt batteries. More wind will increase the charge rate.
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 ship the turbine in a USPS Priority Mail medium flat rate box in order to get YOU the least expensive shipping cost that is possible. We can ship 2 of these turbines in the same box at no extra cost to you.
We ship worldwide and we ship quickly. 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. The only variable will be your available wind.
