One of our oldest Communications Customers said “Every off-grid project is a Picasso”. We understood the meaning: while some of these extremely remote power projects might not be works of art, they are all most certainly ‘one of a kind’; rarely ever the same site, setting or integration. Mission Critical Energy and superwind’s management have decades of international off-grid experience with wind, solar and other remote power and energy storage systems. Part of our commitment to our industry is sharing this knowledge with our clients and staff – something our customers do appreciate.
Our Mission Critical Energy Team understands that there is value we can add – and there are some things best left to others (suppliers and contractors) typically closer to the actual site. The items below go into more detail how we can help our customers.
The front line of our product education strategy is our well trained customer service staff in both North America and Europe. We welcome customers to contact us directly at either Headquarters location – Mission Critical Energy Inc. in the USA, or superwind GmbH in Germany – should they have any questions regarding the superwind turbines or integrations.
Through a number of industry organizations such as the American Solar Energy Association (ASES), The National Defense Industry Association (NDIA) , the Wireless Independent Providers Association (WISPA), and many others, we often present seminars and white papers that are available to the industry. Please visit our News & Event or our Resources sections to see the newest information and schedules.
We have also provided training at the request of Colleges and Universities and at Trade Association Regional Training Centers (including the IBEW).
Depending on the customer need or industry organization’s interest we will gladly consider providing your group with educational materials, educational presentations and if needed: hands on training.
Charge Regulator SCR 12V – 24V
The SCR Marine Charge Regulator has been especially designed for use with the Superwind 350 wind generator, 12V or 24V. It allows the user to fully charge batteries, while also protecting battery banks from overcharging via a diversion load control, as well as temperature compensation.
Wind charge controllers are very different from solar charge controllers in that they are designed to electrically maintain the load correlation with the battery bank while simultaneously producing power above the ever changing battery state of charge. This allows the batteries to be properly charged based on ideal temperature-compensated charging rates and consumer demands.
The Diversion mode initiates when the batteries have reached their maximum charging voltage; the SCR Marine´s PWM
circuit automatically diverts the wind turbine´s surplus power to the diversion resistor block. With this technology, even when batteries are fully charged, the wind turbine continues operating (provides useable power generated when there is ample wind) providing real time power to other electric consumers (loads) as they come online automatically or when switched on manually.
Charge Regulator SCR 48 V for Superwind 350/48 V Wind Turbine
A SCR 48 V Charge Regulator has been specifically designed for use with the Superwind 350 / 48 V wind generator and guarantees optimum charging of the batteries. As long as the actual charge voltage is below the maximum charge voltage level; the current from the wind turbine is fed directly to the battery.
Charge current flow to the battery is indicated by an illuminated GREEN “Charging” LED.
Once the batteries have reached their maximum charge voltage, the PWM circuit diverts the wind turbine’s surplus power to the dump load power resistor in order to keep the voltage constant. This state of charge is indicated by an illuminated ORANGE “Diversion” LED.
Superwind 1250 Turbines, or, the 48v superwind 350
Morningstar Tri-Star 60 (TS-60) Charge Controller Morningstar’s TS-60 ‘ TriStar’ is a three-function controller that provides reliable wind power and solar battery charging, load control or diversion regulation. It is rated at 60 amps, with settings for either 24 or 48 volts DC. An external dump load resistor set does not come with this controller – this item is available from superwind (see below).
External Dump Load Resistor
Superwind 350 Turbines in 12 or 24 volts come with a commercially rated dump load resistor that are designed for enclosed integrations. For those with the need for an external (outdoor rated) dump load system, we make a waterproof one-piece commercial resistor. These external rated dump load banks are ideal for working with either the Schneider C40 or Morningstar TS60 charge controllers.
Superwind 1250 Turbines – All superwind 1250 turbines include an external (outdoor rated) dump load resistor when the turbine is purchased. These external rated dump load banks are ideal for working with the Morningstar TS60 charge controllers in diversion regulation mode.
When we started designing the superwind 350 turbines 15 years ago, and the superwind 1250 in 2008, we kept in mind the limitations and disappointment customers faced from other wind providers in having to buy, and worse yet, ship, expensive dedicated mast systems for their turbines. Thanks to great customer input, any superwind turbine can be installed on locally sourced mast structures, saving shipping costs and often resulting in more appropriate integrations. Ironically, many superwind turbines have been working now for years, after being installed on masts once occupied by other brands’ failed turbines!
After helping thousands of clients acquire and integrate wind turbines around the world,we have collected quite a large variety of mast and tower integrations into our knowledge base. A majority of our customers in the commercial and industrial worlds do allow us to share this information with other clients. We also have the lateral thrust data to help your tower engineer or contractor understand the real world wind loadings, so as to build the best support for your site.

Superwind 350 Turbine Mast Strategy
Instead of forcing customers into a ‘one fit’ clamp-over design for masts, superwind developed an internal bushing mast integration system for all superwind 350 turbines, allowing for great variation in mast structures and materials. The system is based on a fixed Yaw-Shaft size that can fit into different sized mast mounting bushings that can then fit into standard tube and pipe sizes available in the world. These bushings are typically stainless steel, but for certain applications we also make several sizes in Delrin (saltwater-proof plastic). A quick look to the bushing section of our SW350 Manual illustrates that most of the masts work around the use of any 2” schedule 40 metal pipe (very common materials in North and South America) as well as E.U. standard pipe sizes. The mast can be aluminum pipe, cast drill pipe, steel, stainless, etc.
Superwind 1250 Turbine Mast Strategy and Mounting Flange
Because of the weight and higher loadings (the 1250 has 4 times the swept area of the superwind 350) the internal bushing system of our smaller turbine was not appropriate for the 1250. Instead, we created a standardized flange system that is heavy duty enough to mount the turbine, and easy to assemble using standard tools.
The 1250 turbine Yaw Shaft itself makes up the top of the flange pairing allowing a strong tight connection to the top of the desired mast. This smart design allows for a wide range of mast integrations and allows for a variety of mast fabrication materials that can be used – often sourced locally to the project site.
FMR-1250 Mounting Flange Ring
Drawings to make your own flange to weld to the top of any quality metal mast system, pipe or tapered pole are available and FREE – but based on real customer interest, we also sell an optional pre-made flange ring (part number FMR-1250). The ring is pre-drilled, a mirror face to the turbine base flange, and ready to weld onto any high quality steel mast. Shipping this flange mounting ring only, rather than the entire mast, is a cost saving strategy for your superwind integration.
Again, we are big believers in using local contractors – and we will assist the customer, their fabricators, and their installation crews with all the information and support possible. We have a number of mast related downloads available including the drawings for the superwind 1250 mast ring, as well as our well known “Border Box” 10’x10’ sea-can integration system.
Most our customers who have asked for the 1250 to be built had permanent mast towers in mind. These integrations could be free standing tapered mast poles, guided telescoping pipe stands, or the tops of properly sized triangle towers. What is important is not to just account for the 1250 turbine’s weight, but more importantly the 360 degree lateral thrust forces (from the wind itself) on the mast structure as well as the wind turbine. Again, since our 1250 turbine blades ‘feather’, the lateral thrust produced by the superwind 1250 is much lower than other similar sized wind turbines. Also remember that just because the superwind 1250 turbine is larger than the 350, doesn’t mean it cannot be made useful in mobile or re-deployable applications. A simple hinged base system combined with a properly sized hand crank or winch may allow for easy installation as well as rapid and repeated deployment.
