Superwind 1250 Turbine

A brief history…

SW1250 (2011)

Within just a few years of the introduction of the Superwind 350 turbine, featuring ground breaking technologies such as an auto-feathering blade set, extremely low noise levels and game-changing survival ability in high winds and storms, our best clients started asking us to consider making a larger wind turbine with the same attributes as the SW350.

As more clients started integrating our turbines into large off-grid projects (often to save underpowered solar systems), it was not unusual to see large groupings of our smallest turbines helping with the heavy lifting at high peak load sites.

In 2008 we could no longer ignore the customer demand for something larger than the Superwind 350 – and something much more dependable than the cheap and unreliable 1000 Watt turbines widely offered on the international market. We polled our customers and listened carefully to fully understand all of their needs.

The result is that we understood the new ideal 1000+ Watt turbine would include even more technology than what was in the SW350 at that time. R&D to create such an ideal turbine was not going to be fast or inexpensive to be accomplished correctly – and it should never be done (as many wind companies do) as ‘experiments on customers’ nor on the backs of small investors. If the SW1250 was going to be to the same high standards as the SW350 turbine, it would have to be a true and honest long-term investment in micro-wind technology. Believing in that vision, Mission Critical Energy Inc. and superwind GmbH signed a co-development agreement in April 2008 to develop the Superwind 1250 without government grants and with only our own private funding. As with other Superwind turbines, the development was a total ‘wind turbine system’ approach strategy – and would be designed, engineered and manufactured in Germany by superwind GmbH. And Mission Critical Energy, Inc. would provide the integration strategies, manuals and important customer feedback to loop back into our engineering & design.

In 2012 the SW1250 débuted at the Navy Leagues’ Air Sea Space Exposition in Washington D.C., letting the world know we were starting the process tooling up for higher quantity production while maintaining our high quality standards.

NEW TECHNOLOGY:

Our customers had also asked us for a full stop brake system – more than just a short circuit magnetic brake that allows the turbine to spin in high winds. What this means for our marine auhority and telecommunication customers is that no matter the wind conditions, our customers can bring the turbine to a complete stop, allowing tower climbers or technicians to safely work near the turbine at any time they need to.

OUTPUT OPTIONS:

In meeting the new USCommercial Utility Standard of 2013, the Superwind 1250 is available in 48V as well as 24V – also known as 28.8V

The Superwind 1250 actually produces its rated power of 1250 watts at only 11.5 m/s, which is below the internationally accepted wind rating speed of 12.5 m/s. The bottom line (to this data) is that we make more power at average wind speeds than anyone had hoped. Of course, energy output is a factor of available wind energy, so knowing your sites’ unique characteristics is key to planning. – click here for the actual 1250 power curve at varied wind speeds.

Even Better.

With the successful development of the superwind patent pending STAR Hub system (Synchronous-Technology-Autonomous-Rotor) released in 2017, every SW1250 now comes with this wind technology advance – as a standard component. Our Superwind 1250 continues its work in the real world making mission critical power for customers who appreciate well engineered and finely built equipment, have high load demands, and for whose sites have good available wind energy despite being in very remote areas with harsh conditions.

OPERATION:

The SW1250 turbine, like its smaller SW350 cousin, is also extremely quiet! We utilize the best balance procedures, the highest quality components and turbulator technology on our airfoils to keep vibration and noise to a minimum.

Integration of the Superwind 1250 into new or existing systems is not at all difficult. In fact, our recommended installation method always features PWM dump-load resistor systems to not only insure your batteries are being charged fully and properly, but also to protect your battery bank from harm – even in multi charging source projects.

Of course we also welcome you to contact any of our experienced staff or authorized international sales agents at any time. We are happy to help you better understand the equipment and to find out whether it will be a benefit to your project.
