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.
Additionally,
this
device
must
keep
the
MG
Rover
Wind
Turbine
under
an
electrical
load
while
the
MG
Rover
Wind
Turbine
is
not
charging
the
battery
bank.
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
