1. SAFETY
Your wind turbine is designed with your safety as the 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 carefully read the following:
Important Safety Instructions
Carefully go through this manual before initiating the wind turbine
installation.
(1) Keep this instruction manual safely for future reference.
(2) Wait for a sunny day to install or for maintenance work on your wind
turbine with the activation of the manual stop switch.
(3) Listen to your wind turbine if you hear any mechanical noise, maintenance
may be required, please contact the Products Customer Service.
(4) After installation, double-check all the screws and bolts to make sure they
are tightened.
(5) Adhere to proper grounding techniques as established by the National
Electrical Code (NEC).
(6) Your wind turbine must be installed as per this user manual and the local
and national building code of your region. Incorrect installation may void
your warranty.
(7) Wind turbine blades spin at a potentially dangerous speed, this must be
respected. Never approach near to the turbine when it is in motion.
(8) Note wire size (gauge chart included) before 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 glass fiber & polypropylene and the blades may
reach velocities over 15 m/s. At this speed, the tip of the blades are nearly
invisible and can cause serious injury. Under no circumstances the turbine
should be installed in locations where a person could come in contact with
its moving rotor blades.
1.2 Electrical Hazard
The wind turbine is equipped with sophisticated electronics designed to
protect from electrical dangers. Please note that the inherent personal
dangers from electrical current still exist, therefore caution should always
be taken while connecting this and other electrical devices. Heat in a wiring
system is often a result of excessive current owing through an undersized
wire or a weak/damaged connection. Please consult the wire guide table
below.
Batteries can deliver a dangerous amount of current. If any short circuit
occurs in the wiring from the batteries, can result in a re break-out. 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
Before the installation of your wind turbine, you must carefully consider a
location. Things to consider when selecting your wind turbine location.
(A) Height and Distance from obstacles like buildings, trees:
• Install the wind turbine in open and windy sites so, the turbine will be
exposed to winds properly and the benet can be maximized. A distance
of 7-10m should be maintained.
• 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.

B) Distance from human habitat.
• Install your turbine with some distance from the human activity areas as
not to disturb your neighbors and animals around. The noise and
vibration element cannot be got rid of even if this wind turbine offers
the lowest noise than any others on the market. The better location of
your turbine requires 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 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 low wind
power availability.
b. The stress the pole kit sustains varies in rooftop constructions.
Evaluation and stability cannot be guaranteed.
c. The slight noise and vibration still aect sleep for some sensitive
people and animals.
C) Distance between the wind turbine and battery bank.
D) Any local zoning restrictions.
E) Clearance of power lines or any overhead connection.

* The Manual stop switch should be activated when the wind speed upwards
of 30mph (13 m/s).
* Survival wind speed means that the wind turbine will survive at 112 mph (50
m/s), when the Manual stop switch is turned on. Exceeding this will result in
wind turbine failure and collapse.

2.3 Wiring Requirements
12V Volt System, AWG / Metric Wire Size mm
Please refer to the recommended wire gauge table and select
the appropriate wire size for your system.
Distance between Turbine
and Battery Bank 0 - 30 ft. (0- 9 m) 0 - 70 ft. (0- 21 m)
Wire Gauge 10/6 mm 8/10 mm

7
Caution 1: Any usage of under-sized wire can be potentially dangerous; our
warranty does not cover damages caused by using an incorrect wire gauge.
Distance between turbine and the battery pack should be kept as low as
possible and should not exceed more than 30 meters for safety reasons (Be
sure to include the height of the turbine).
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
between the wind turbine and the battery pack for optimal performance.
Always use the largest gauge wires that are practical and affordable. Local,
state, and/or national electrical codes take precedence over these general
recommendations.
3. SYSTEM PROTECTION
3.1 Digital-controlled MPPT
Your turbine comes equipped with state of the art overcharge protection.
When the temperature of the turbine exceeds 80°C (176°F) your turbine will
automatically shut down and apply the braking system to your wind turbine
to prevent damage.
High battery voltage protection 14.8V
Overcharging current protection 20A
Over-speed protection ≤1200 rpm
Overheat protection for the generator ≤900 rpm and 70 sec.

3.2 Manual Stop Switch
The wind turbine has a built-in controller with braking device protection.
Further to this protection, we have incorporated a secondary level of safety
and convenience with a manual brake.
During periods of high winds (upwards of 30 mph, 13 m/s) it is strongly
advised to utilize your manual stop switch. The use of your manual stop switch
will not aect the voltage of your battery.
We strongly advise the activation of the manual stop switch during any
maintenance of or around your wind turbine. This will prevent the blades from
spinning and voltage to be transferred.
Likewise during initial installation please activate the manual brake. After the
installation of the turbine manual stop switch should be released.
The manual stop switch is pre-wired for your convenience with 8 AWG wire
and battery terminal connections. The wire conguration is explained in the
diagram below (page 9). Connect the corresponding wires of the manual stop
switch to the turbine. The red (+) wire of the stop switch should match with
the red wire of the turbine. The yellow wire (BRAKE) of the stop switch should
match with the yellow wire of the turbine. They should match the correct
wires from your turbine. This provides a parallel connection.
Test the connection of your manual 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 manual stop switch under any
circumstance!

5. INSTALLATION PROCEDURE
Step 1 : Open box and ensure all parts are present.
Step 2: Carefully observe windmill layer for easy and quick installation.
Step 3: Install the wind turbine to your chosen tower and fasten the bolt
securely by using the hex key (The Yaw Shaft includes a rubber spacer to
ensure the connection is secure).
How to select your tower: The outside diameter of the iron pipe should
be 48.3 mm, the thickness of the iron pipe should be at least 1.9 mm.
Caution: Ensure that rubber spacer is attached to the tower pole prior to
turbine installation, otherwise the turbine will be too loose and unable to
sustain vibrations.

12
Step 4 : Fasten the blades on the hub with nuts by using the hex key and
unilateral open wrench. (Make sure that all of the bolts are secured with nuts.)

13
Step 5 : Fit the nose cone onto the hub by applying a gentle pressure to
ensure a secure t.
Step 6 : Final product diagram.
Note : The wind turbine pole kit is not included with the unit.

14
Caution:
After installing, check and make sure that there is no ange/ coupler/ support
cable ring lies within 1.7 m from the wind turbine center/ hub. Cylindrical
shape poles are recommended for installing the turbine and there should be
sucient free space/ gap between the pole and the wind turbine blades as,
during the wind gust, blades bend a little towards the inside. Refer the image
below for a better understanding.
