![]() This is simply a great turbine and super economical. This tested unit produced 1041 watts at 468 RPM which would be approximately 26 MPH. Since it's somewhat difficult to read the wind speed values, they are 6, 18, 26, 30 and 35 MPH. This turbine is capable of running at 1000 watts continuously without heat damage! It should be noted that at the higher end, these values will be only seen for short intervals since the turbine will furl to prevent overheating. Wind speeds have been estimated based on both known results (turbines we have on towers) and extrapolation of data based on various loading factors including wire resistance, blade TSR, heat dissipation etc. Data is for our 1000 watt turbine into a 24 volt battery bank. The following chart represents data achieved via our precision test bench. Please add $40.00 for 12 volt model due to increased size and cost of the rectifier. ![]() The turbine handled the abuse very nicely, with no overheating. During our testing period, we allowed it to freewheel (took all loads off), then we connected loads as it was spinning at great speeds. ![]() It uses both autofurling fiberglass blades as well as furling tail that will bring it out of very strong winds. We have tested this model in very strong thunderstorms here with heavy gusts. This allows a very nice disconnect, and a means to allow the cable to untwist if needed (rare). Simply cut the male end off, terminate that end at the turbine, then use it (the end you cut off) to plug into the female end at the tower base. These extension cords are perfect for the trip up the tower as they have 3 braided wires (including the ground) and can be easily unplugged if required. We use heavy duty 12 gauge extension cords on the units we have installed here from the tower to the rectifier. The rectifier is a separate unit and can be located anywhere (inside or outside). The turbine is capable of producing over 1700 watts, but 1000 watts is all you should expect to see at wind speeds in the 26 to 28 MPH range. We have tested the alternator on the test bench at over 1000 rpm. The unit begins to furl around 28 MPH and is fully furled in the high 30's. Battery charge voltage is reached at around 160 rpm. Included is a 3 phase rectifier to convert the A/C into D/C which can be used to charge batteries, or run a suitable grid tie or stand alone inverter. This is a 3 phase permanent magnet wind generator. This mill is built tough and should serve you well, even in harsh (non-corrosive) conditions.ĭon't be fooled by the units being producted that promote 900 watt outputs at 45 mph! - Just how often does that occur (and how long do you think the turbine would take that abuse without furling.) Once a year the bearings should be packed and yaw bearing greased. This turbine will last for years with minimum maintenance.
