1. SAFETY
Your wind turbine is designed with your personal safety as the first
priority. However, there are still some inherent dangers involved with
any electrical and/or mechanical equipment. Safety must be the primary
concern as you plan the location, installation and operation of the turbine.
Please read the following:
Important Safety Instructions
Please take the time to read through this manual prior to assembly.
(1) Place this instruction manual in a safe place for reference.
(2) Wait until a calm day to install or perform maintenance on your wind
turbine with activation of mechanical stop switch.
(3) Listen to your wind turbine should you hear any mechanical noise,
maintenance may be required, please contact The Products Customer
Service.
(4) After installation re-adjust and tighten the screws and bolts.
(5) Adhere to proper grounding techniques as established by the National
Electrical Code (NEC).
(6) Your wind turbine must be installed in accordance with this manual
and local and national building code. Incorrect installation may void
your warranty.
(7) Wind turbine blades spin at a potentially dangerous speed this must
be respected. Never approach a turbine in motion.
(8) Note wire size (gauge chart included) prior to wiring. Any under sizing
of wire can be potentially dangerous.

1.1 Mechanical Hazard
Rotating blades present the most serious mechanical hazard. The rotor
blades are made of very strong thermoplastic. At the tip, the blades may
be moving at velocities over 15 m/s. At this speed, the tip of a blade is
nearly invisible and can cause serious injury. Under no circumstances
should you install the turbine where a person could come in contact with
moving rotor blades.
1.2 Electrical Hazard
The wind turbine is equipped with sophisticated electronics designed to
provide protection from electrical dangers. Please note that the inherent
personal dangers from electrical current still exist, therefore caution
should always be used when connecting this and other electrical devices.
Heat in a wiring system is often a result of too much current flowing
through an undersized wire or through a bad connection. Please consult
wire guide table below.
Batteries can deliver a dangerous amount of current. If a short circuit
occurs in the wiring from the batteries, a re can result. In order to avoid
this threat, a properly sized fuse or circuit breaker is required in the lines
connecting to the battery.
Choosing your wind turbine’s location
Prior to the mounting of your wind turbine, you must carefully consider a
location.Things to consider when thinking about your location
A) Distance from any obstacles that will cause turbulence, trees,
• Locate your Turbine in windy sites so as not to disturb neighbors
and animals around. The noise and vibration element cannot be
got rid of even if this wind turbine o󰀨ers the lowest noise than any
others on the market. The better location of your Turbine requires

3
avoiding personnel or animal activities within a 33 ft (10 m) radius,
and human habitation and wildlife within a 66 ft (20 m) radius.
• The minimum recommended tower height is 22 ft (7 m) to 33 ft (10
m). The wind speed below 22 ft (7 m) constrained by the terrain is
low and chaotic.
For example: If wind in your area is more than 30 mph (13.4 m/s),
the height of 22 ft (7 m) is recommended. The higher the Turbine
stands (more than 10 m), the much stress your pole kit will sustain.
Also, the Turbine possibly brakes in extreme weather conditions.
• The rooftop may not be the best place for your Turbine. Here are
three reasons.
a. The ow is more turbulent above the rooftop and leads to the low
wind power availability.
b. The stress the pole kit sustains varies in rooftop constructions.
The evaluation and stability cannot be guaranteed.
c. The slight noise and vibration still a󰀨ect sleep for some sensitive
people and animals. The rooftop may not be the best place for
your Turbine. Here are three reasons.
B) Distance from MPPT controller and battery bank
C) Any local zoning restrictions
D) Clearance of power lines

2. SYSTEM SPECIFICATION
2.1 Specication
* The mechanical stop switch should be turned on when the wind speed
upwards 35 mph (16 m/s).
* Survival wind speed means that the wind turbine will survive at 112
mph (50 m/s) when the mechanical stop switch is turned on.
Exceeding this will result in wind turbine failure and collapse.
2.2 Performance
The following power curve shows the performance you should expect
from your wind turbine. During smooth, steady wind speed, you can
expect to see output resembling the curve illustrated below. To convert
between power and current use the following formula:

Caution 1: Any under sizing of wire can be potentially dangerous; our
warranty doesn’t cover damages caused by using incorrect wire gauge.
The distance from the MPPT to your turbine should not exceed 60 meter
for safety reasons (Be sure to include the height of tower).
Caution 2: Please review the above wire gauge table to install the correct
wires. We recommend these as the minimum wire sizes for the distance
from the MPPT to your turbine for optimal performance. Always use the
largest gauge wires that are practical and a󰀨ordable. Local, state, and / or
national electrical codes take precedence over these general recomm-
endations.

1. Under normal situations, the green V LED should be lit once connected
to a battery.
2. When the SET button is pressed, the green V and I LED’s will be lit alter
nately, the voltage, current and total accumulated wattage (kWh) mea
surements will be shown on the LCD screen.

3. If the green V and I LED’s ash at the same time, it means that your
system is in its protection (brake) mode. To evaluate the problem,
further press the SET button, and the LCD display will show a set code
PR1~PR7. Refer to the description listed above to know what each
code stands for.
System protection: Your MPPT charge controller, equipped with
sensors inside the unit, comes with four main protection functions.
Self-protection: The MPPT charge controller has a temperature sensor.
Temperature of the internal circuitry is moderated by an internal fan that
is activated at 45°C (110°F).When the temperature exceeds 65°C (150°F),
the MPPT will apply both the fan and braking system to prevent damage.
Protection for Battery: The MPPT charge controller can sense the
voltage of battery and the current output/input to battery. If the parameter
of voltage and current is wrong, then the braking system will be turned
on.
Protection for Wind Turbine: The MPPT charge controller can sense
the rotation speed of wind turbine. If the rotation speed is over the
setting value in program, the braking system will be turned on. The latest
version of MPPT charger controller is also equipped the phase detector
technology. If the AC output wave from generator is incorrect, that means
the generator may be damaged. At that moment, the MPPT will apply the
braking system and the LED lamp to warn users.
Protection for No Battery Connection: When the MPPT charge
controller shuts down due to the abnormal battery and improper
connection; it will cause free-spin issues. At 150 RPM and above, the
MPPT charge controller should apply the braking system automatically
and the power from the wind turbine should be cut o󰀨 at once. The wind
turbine will turn on and brake repeatedly. Under safety condition, please
check the battery wire and function as soon as possible.

3.2 Mechanical Stop Switch
The MPPT controller has an integrated battery controlled braking
mechanism. Further to this protection we have incorporated a secondary
level of safety and convenience with a mechanical 3-phase AC brake.
During periods of high winds (upwards of 35 mph / 16 m/s) it is strongly
advised to utilize both MPPT brake and mechanical stop switch. The use
of mechanical stop switch will not a󰀨ect the voltage of your battery.

Mechanical Stop Switch
Turbine

We strongly advise the activation of the mechanical stop switch during
any maintenance of or around your Turbine. This will prevent the blades
spinning and voltage to be transferred. Likewise during initial installation
please activate the mechanical brake. The final step in installation of
Turbine, controller, and battery should be release of this mechanical stop
switch.
The mechanical stop switch is pre-wired for your convenience with 10
AWG wire and battery terminal connections. Place the corresponding
wires (Red, Black, Blue) from the mechanical stop switch into the MPPT
input terminals. They should match the same colored wires from your
Turbine. Your Turbine and stop switch share input terminals on the MPPT,
this provides a parallel connection.
Test the connection of your mechanical stop switch at the point of initial
installation. Push the brake “ON”. You should see the Turbine stop
its rotation. Continue to apply this brake during the remainder of your
installation. Should the Turbine continue to spin, check your terminal
connections. Do not approach the Turbine without activation of this
mechanical stop switch under any circumstance !
• It is strongly advised to test both mechanical stop switch and MPPT
periodically.
• The mechanical stop switch is pre-wired with 10 AWG wire, this should
not be altered.
• The mechanical stop switch should be placed close to your MPPT in a
dry ventilated environment.
• For multiple turbine applications please use one mechanical stop switch
for each wind turbine.
• This mechanical stop switch has been designed specically for your wind
turbine; it should not be incorporated into other models.
