    Weight: 40 lbs (18 kg) Upon opening, carefully inspect each of the blades to make sure there are no fractures or cracks in the surfaces. Although the Skystream rotor blades are comprised of a durable compression molded fiberglass, damage can occur to the blades during shipping. Once inspected, be sure to set them away from the construction site and protect them from any damage until they are ready for assembly.

    1-3 Skystream Options There are a number of options that can enhance the experience of using a Skystream wind appliance. Although your Skystream will operate without them, we suggest reviewing this chapter. Contact Southwest Windpower or your dealer if you have questions.

  • Page 9: Skystream Project Preparation

    Proper siting is essential to a well performing wind generator. The taller the tower, the more energy your Skystream will produce but keep in mind, this will also increase the cost of the installation. It is extremely important to balance performance (tower height) to installed cost in order for you to achieve the lowest cost of energy and quickest payback.

  • Page 10: Tower Types

    Like your utility, the local planning and zoning authority may or may not have experience with an individual installing a small wind generator at their home or small business.The most important issue is the height of the tower. Prior to purchasing your Skystream tower, check for local zoning limitations.

  • Page 11: Installation

    You will notice the rotor shaft on Skystream is extremely difficult to turn.This is normal. As a safety precaution, the default position of Skystream is in brake mode when the inverter is disconnected from the utility-supplied power.The reason is if there is a fault in the utility line, Skystream must shut down to prevent back feeding of electricity into the line while it is being repaired.

    Again, it is extremely important to install in accordance with local and national zoning regulations. Note: Only 20 Amp circuit breakers may be used to connect Skystream to AC service panel. Refer to Fig. 3, wiring diagram. 2-1-6 Checking correct grid connectivity Fig.

  • Page 15: Installing Skystream On A Tower

    2-2 Installing Skystream on a Tower There are several types of towers that can be used with Skystream. It is essential that Skystream is installed on a properly engineered tower. One of the leading causes of wind generator failure is use on a poorly designed tower.

  • Page 16: Mounting Skystream To The Tower

    Though Skystream is thoroughly tested at the factory, it is very important to conduct one more test prior to erecting the tower. Skystream should be wired and mounted to the top of the tower.The blades should not be attached.To do this test, you must have all wires and breakers installed with at least one disconnect switch open (off).

  • Page 19: Key Operating Characteristics

    Skystream will begin producing power in a wind of approximately 8 mph (3.5 m/sec). At that speed the blades will rotate at approxi- mately 120 rpm. As the wind speed increases the blade speed will also increase until at about 20 mph (9 m/sec) wind speed the blade speed achieves a rotational speed of 325 rpm.This is Skystreams rated speed.

    3) What should I do if I’m expecting a severe storm? The Skystream is designed for very high winds, but it is always a good idea to shut Skystream down if there is going to be a severe storm to protect against any flying debris.

    IMPORTANT SAFETY INSTRUCTIONS READ THESE INSTRUCTIONS IN THEIR ENTIRETY BEFORE INSTALLING. Professional installation highly recommended SAVE THESE INSTRUCTIONS. This manual contains important instructions for raising, lowering and leveling the tower that must be followed. In this guide Read these instructions in their entirety before beginning the installation. TIP: Helpful information Be extremely careful of overhead power lines.

  • Page 38: Introduction

    One - Introduction These instructions require use of Southwest Windpower’s Hinge and Gin Pole Kits, which were specifically designed for this application. Additionally, these instructions assume a bolt kit was purchased and the correct foundation nuts, bolts and washers are available. Once the tower is raised into position the hinge and gin pole are removed.

  • Page 39: Set Up & Preparation

    Two - Set Up & Preparation Carefully read and perform the following steps to prepare for raising the tower. TIP: Approximately 90 feet • Determine the three foundation bolts to be used to mount the hinge.The hinge (43 meters) are required to raise the tower vertically is installed in the direction the tower will be “tilted down”.
  • Page 40 • Tighten the hinge plate nuts such that the top of the hinge plate is 4 1/4” (10.8 cm) from the top of the foundation bolts. WARNING: The 4 1/4” height adjustment is VERY important to insure the foundation bolts will clear 4.25”...

  • Page 42: Raising The Tower

    Three - Raising the Tower Refer to your Skystream Owner’s Manual for directions on mounting Skystream on the tower. If you have not raised a tower before it is also recommended to first raise the tower without the turbine. Raising the tower without the turbine provides the opportunity to prac- tice the procedure without risking damage to the turbine.

  • Page 43: Lowering The Tower

    Four - Lowering the Tower WARNING: Use extreme caution Lowering the tower is essentially the reverse of raising the tower.The same pre- when lowering the tower. Keep well cautions should be observed, including positioning the hinge so the tower base away and to sides of tower and cable.

  • Page 44: Leveling The Tower

    To level the tower: • Level the tower on a calm day to minimize movement of Skystream. Start by loosening all the upper foundation nuts about a full turn. • Loosen and lower the four nuts on the “sides” of the foundation base plate. In other words the tower should be supported by the four “corner”...
