Page 3: Overview
SeaHawk can also be connected to the power grid. The SeaHawk turbine consists of a .762 meter x 1.2 meter (2.5 ft. diameter, 4 ft. high), 63.5 - kilograms (140 lb) wind turbine rated at 1,000 watts and a multi-function turbine and system controller made by MorningStar Corp.
Page 4: Cautions And Warnings
Significant points of interest 3. Identification Each SeaHawk vertical axis wind turbine has a serial number located on the bottom of the generator. The Serial Number is also written on the box that the turbine came in. We recommend writing it here as well: PacWind SeaHawk Serial No.:...

42.75 m/s (95 mph). The SeaHawk just appears as wind loading at that point and the wind simply goes around the SeaHawk as it is putting out full power. The SeaHawk puts out maximum power at about 27 m/s (60 mph).
Page 7 D. SeaHawk Wiring The basic electrical schematic for the SeaHawk is shown in Figure 5. The SeaHawk’s PMG produces three-phase alternating current (AC) that varies in voltage and frequency with the rotor speed. The AC power is rectified to direct current (DC) power by a rectifier module inside the PMG.

203.2 mm (8 in). If you are using the SeaHawk Tilt.Tower then the SeaHawk will bolt directly in place. If you are mounting the SeaHawk to a different type of tower then you will need to ensure that the tower meets the requirements for SeaHawk towers (see Appendix) and that it has a proper adapter fitting for attaching the SeaHawk tower mount casting (also defined in the Appendix).
Page 9 7. MorningStar TriStar TS-60 Controller Installation A. Electrical System The general electrical configuration for SeaHawk and hybrid system installations is shown in Figure 8. In most cases the loads will be D.C. and can be directly connected to the battery bank.
Page 10: Trouble-Shooting
A basic trouble-shooting guide is located in the MorningStar TriStar TS-60 manual. For operational problems with the SeaHawk wind and for problems or symptoms not found in the MorningStar TriStar TS-60 manual, please contact the Service Department at PacWind at:...
Page 11: Appendices
Appendix 1 Installation Planning The location and height of the tower for the PacWind SeaHawk wind system will be important factors in determining the overall performance of the system. Average wind speed is influenced by many things and may vary considerably within a relatively small region, particularly in complex terrain.
Page 12 The SeaHawk wind turbine must be placed on a tower that is tall enough to give the cage proper exposure to the wind. Putting a wind turbine on a tower that is too short is like installing a solar system in the shade.
Page 13 Table 2: Variation in wind speed and expected relative energy output with tower height. We do not recommend mounting the SeaHawk to a home and we suggest caution if installing one on a larger, more substantial, building. Our concerns are 1) the forces on the turbine and mounting system are substantial and homes are not designed structurally for them, 2) the air flow around and over a home or building is complex and can cause considerable turbulence.
Page 14 As a general rule, wire runs over 100 meters (330 ft.) if buried or 200 meters (650 ft.) if installed overhead should be avoided because of their high costs. On the SeaHawk it is not possible to use transformers to increase the wire run voltage because the wire run is direct current (DC).
Page 15 If a wiring junction is made at the base of the tower then a watertight junction box should be installed for the connections. The recommended wire sizes for the SeaHawk wind turbine are shown in Table 3. The listed distances include the height of the tower.

Page 18: Appendix 3 Basic Tower Requirements
Appendix 3 BASIC TOWER REQUIREMENTS For the SEAHAWK Wind Turbine Customer supplied towers for the SEAHAWK Wind Turbine should meet the following minimum requirements: Tower Height: 9 m (30 ft) minimum, though we recommend 18 m (60 ft) or higher Design Wind Speed: 54 m/s (120 mph) Turbine Weight: 35.8 kgs (79 lbs)
Page 19 Materials: We recommend low-carbon steel towers, with careful attention given to weld quality. Stress risers and brittle materials must be avoided because of the possibility of fatigue and cracking. We do not recommend aluminum be used due to the risk of cracking. Fasteners should be U.S. Grade 2 or Grade 5 or equivalent.
