PacWind SeaHawk Owner's Manual - Caution
applications. For rocky soils, or runs underneath roadways, we recommend that the underground
wire run be installed in conduit. 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.
Maximum Current:
60 amps
Caution
Installing wire sizes larger than those recommended will increase the maximum current produced
by the turbine.

Table 3: Recommended Wire Sizes for the
SeaHawk
Note: These wire sizes have been engineered to provide optimum rotor loading for the
SeaHawk
wind turbine.
Deviation from these recommendations can result in decreased performance from your machine and / or
unnecessary additional wire-run costs. The use of a wire gage one size larger than the recommended size is
recommended if aluminum wire is used.
Before assembling the wind turbine the tower wiring must be in place, though not necessarily
permanently affixed. We recommend that you leave at least 30 cm (12 in) of free wire at the top
of the tower for making the electrical connections to the wind turbine.
E. Other System Components
A complete remote power system will include other electrical components such as a solar array
(optional), a battery bank (required), a dump load (optional), and an inverter (optional). These
components are sometimes called the “balance of system” or BOS equipment.
The wind turbine and the other BOS equipment are electrically connected in a “DC-bus”
architecture, as shown in Figure 6. The DC-bus architecture is robust and very flexible, allowing
endless options for multiple and differing components.
The unifying feature is that all of these components are electrically connected to the positive (+)
