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 thermoplastic 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 any obstacles that will cause turbulence, trees,
• Locate your turbine in open and windy sites so, the turbine will be expo-
sed to winds properly and the benet can be maximized.

• 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 the 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
may get damaged in extreme weather conditions.
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 from MPPT controller and battery bank.
D) Any local zoning restrictions.
E) Clearance of power lines or any overhead connection.

*The 400W wind turbine operates in between 0-15V output voltage, we highly
recommend using 8 AWG wire and maintaining a distance of 30-60 meters.
between the turbine and battery. Using an inappropriate wire gauge will
result in wind turbine failure.
**Please activate the manual brake when the wind speed exceeds 30 mph (13
m/s). The survival wind speed means the turbine can survive the winds up to
112 mph (50 m/s) when the brake is manually activated. Exceeding the wind
speed 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:

2.3 System Protection
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.
12V Volt Systems, AWG / Metric Wire Size mm
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.
The distance from the MPPT to your turbine should not exceed more than 40
meters for safety reasons (Be sure to include the height of the turbine). The
distance between the MPPT and the battery pack should be kept as low as
possible and shouldn’t be more than 3 m and the wire gauge used should be
6 AWG or 16mm2 or at-least 8 AWG.
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 affordable. Local, state, and/or national
electrical codes take precedence over these general recommendations.

2.4 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 and battery 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 7). 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!

6. MAINTENANCE
Your wind turbine has been designed to run for long periods without
requiring any maintenance. The performance will be enhanced if you
periodically inspect your system. Review the following simple maintenance
procedures and implement them every six months.
Caution 1: Do not go near the wind turbine during operation.
Caution 2: The blades are sharp. Please handle with care.
• Check blades for supercial damage, replace the blades if damaged.
It ' is important to not use blades that are damaged, as you will lose overall
balance, resulting in a declined performance. Should you notice damage to
the blades you must replace all 3, these blades are balanced as sets.
• Check the blade bolts and the hub nut for tightness.
• Check nose-cone for cracks and tighten nuts.
• Wipe any excess dirt build-up from the blades.
• Check all electrical connections to make sure they are tight and free from
corrosion.
• Check the voltage of your battery bank with a Multi-meter and clean the
terminals.
• We suggest replacing the blades every ve years for optimal performance.

7. FAQS
(1) How does the wind turbine control power and RPM in high winds?
Your Turbine’s operation will be halted to reduce the risk of damage due
to overcharge and over-spin of the rotor blades. This process of braking is
handled internally through your Turbines electronics.
(2) What is the maximum wind speed the wind turbine will survive and do I
need to take it down in a storm?
Your wind turbine is designed to operate in most climatic conditions. Should
you expect or experience winds of 110 MPH upwards, please manually
activate the brake. Once the Turbine has stopped it is possible to lay down the
Tower to oer further protection.
(3) How long will the bearings or other wearing parts last?
According to engineering calculations, the bearings should have a 10year life
span in 12 mph (6 m/s) average wind speed sites. Bearing life will vary from
one application to another; however, you should expect at least a five-year
performance in adverse conditions and 10 years in normal conditions.
(4) Can the wind turbine be connected in reverse-polarity to the battery
without causing any damage?
Reverse polarity will cause damage to your battery if not quickly remedied.
Always double check any wiring to reduce the risk of reverse polarity. Your
turbine is equipped with polarity protection to reduce the risk of damage,
but it is still possible to degrade your wiring and cause damage to the overall
system.
(5) Will, it hurt my wind turbine to short-circuit the output?
No, the wind turbine is designed to be short-circuited as a normal shutdown
procedure by a fuse. The function of the stop switch is to disconnect the
turbine from the batteries as well as short-circuit the output of the turbine.
