Step 2:
Place a flat washer on a bolt. Slide the bolt through its respective hole on the blade and
hub. See Picture A in Figure 5 above. On the backside of the hub, attach the k-‐lock nut to the
bolt as shown in Picture B of Figure 5 above. Repeat this process until all the blades are bolted
to the hub.
It is necessary to tighten the k-‐lock nuts to a torque of 9.0 lb-‐ft (12.1 N·∙m).
Section 4.0: Final Assembly of the MG Rover Wind Turbine
The MG Rover Wind Turbine is now completely assembled and mounted on the
tower. Before continuing, look over the entire wind turbine to be sure everything is attached
correctly and securely. In particular, pay special attention to all fastener connections and wire
connections.
Section 5.0: Locating a Site for the MG Rover Wind Turbine
If mounted incorrectly, trees, buildings and other tall objects will block the wind available to all
wind turbines. For best performance of the MG Rover Wind Turbine, it should be mounted 20
feet above all objects within a 100 foot radius. If you are mounting the MG Rover Wind Turbine
on a sailboat or recreational vehicle (RV), it will probably not be possible to mount the Rover
Wind Turbine 20 feet above all objects within a 100 foot radius. In this case, mount the MG
Rover Wind Turbine as high as safely possible and, also, mount it in a location where it has the
best unobstructed access to the prevailing winds of your site.
Section 6.0: Main Operational Characteristics of the MG Rover Wind Turbine
Electricity production and regulation
The MG Rover Wind Turbine produces energy by capturing kinetic energy from the wind. The
wind is captured by blades which use the wind’s kinetic energy to rotate a three phase AC
permanent magnet alternator. The rotation of the permanent magnet alternator (PMA)
produces electrical power which is transferred from the PMA to ground level by three electrical
wires.
At ground level the three phase alternating current (AC) produced by the
PMA is rectified to direct current (DC). This is accomplished by using a three phase bridge
rectifier. Once the three phase AC is rectified to DC, the electricity is used to charge a 12 or 24
volt battery bank.
The MG Rover Wind Turbine requires a device in place to prevent the battery bank from being
overcharged.

To
accomplish both these tasks, a device called a diversion load (or dump load) charge controller is
used. In the most simple terms, a diversion load charge controller is a voltage monitoring
device. The diversion load charge controller monitors the voltage of the battery bank. When
the voltage of the battery bank reaches a level that indicates the battery bank is fully charged,
the diversion load charge controller disconnects the MG Rover Wind Turbine from the battery
