Fortis Wind Energy fabricates horizontal Small Wind Turbines mentioned as HAWT (Horizontal Axis Wind Turbines).
Listed below are the key aspects of our Small Wind Turbines:
- Conforms to IEC 61400-2 international standard
- Upwind, direct drive, fixed pitch, overvoltage protection and emergency braking
- Rectifier & Grid Feed Inverter in one housing
- Power curve according to frequency or voltage
- Maintenance free, 5 year warranty, installation by Fortis Certified System Partner
- Average lifetime of wind turbines is over 20 years
- Made in The Netherlands
The Passaat is our longest running wind turbine type. Thousands of Passaats have found their way across the world in the last decades. The Passaat has a maximum output of 1,4 kW and a span of 3,12 meters.
The Montana is our wind turbine that is most often sold Worldwide. With its 5 meter span it has a maximum power output of 5 kW or as the Montana-Q with 6 kW power.
The Alizé is the largest wind turbine of our product range. Just like the other Fortis Wind Energy Small Wind Turbines, all are maintenance free system. With max. 6.9 meter span blades it provides a maximum power output of 10 kW.
The concept of Fortis Small Wind Turbines:
- Reduce the number & weight of parts to a minimum
- Easy assembly of all turbine parts on site (only bolt & nuts)
- Max. 100 kg per component for easy access to unreachable areas
- Gear less drivetrain / low noise emission
- Direct driven by the turbine rotor (rotor blades)
- PMG and rotor hube form a single unit (same RPM)
- Flexible rotor lengths; adjustable rotor swept area
- Braking system by passive yaw system aligned by a tail vane
- Automatic Brake Switch as a second safety system
- Overspeed protection system is based on the aerodynamic forces on the blades and the weight of the tail
Service & Warranty:
How do we guarantee that our products live up to your expectations? For a start, we are in the wind energy business for over 35 years and the accumulated experience has made both our products as our service reliable.
A reliable system starts with the design. We will assist you in finding the right configuration for your application. Do you need On-Grid or Off-grid, or a combination of wind & sun energy and a heat pump? Our System Partner will support you.
The design of the wind turbines is to international standard conform IEC 61400-2. All our turbines are maintenance free. Using materials as stainless steel, galvanised steel and plastics, we are sure that there will be no corrosion.The blades are made of the strongest glass fibre and epoxy, to make them strong enough to withstand hail or sand storms.
If after all the turbine fails due to a defect in design or manufacture, we have a standard part warranty of 5 years after the date of production started. Download at Support the Warranty certificate for details.
It is trivially obvious, but a wind turbine needs wind.
The higher the wind speed and the smoother the air flow, the higher will be the yield of the turbine. There is a trade-off between positioning a turbine away from all buildings to ensure better air flow (Laminar) and positioning it close to the building where the electricity is used so as to minimise cable losses.
Since the prevailing wind is mostly from the South West, this direction should be clear of obstacles. A building to the north of the site will be of less influence and therefore no problem. If the wind speed is below 4 m/s on average, then we would advise you not to use wind energy due to poor yields.
Especially in the urban environment you face a disturbed air flow that will have a negative influence on your performance. Ground turbulence can also be caused by bushes or other obstacles.
