1. SAFETY
Your Sunforce 600 Watt 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 Turbine.
3) Listen to your Turbine should you hear any mechanical noise, maintenance may be required,
please contact Sunforce Products Customer Service.
4) After installation re-adjust and tighten the screws and bolts.
5) Adhere to proper grounding techniques as established by the NEC.
6) Your Sunforce 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 15m/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 600W 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 fire can result. In order to avoid this threat, a properly sized fuse or circuit breaker is
required in the lines connecting to the battery.

3
Choosing your Sunforce 600 Watt Wind Turbine’s location
Prior to the mounting of your Sunforce 600 Watt 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, buildings etc.
B) Distance from MPPT controller and battery bank
C) Any local zoning restrictions
D) Clearance of power lines
In general terms the higher the tower the less obstruction to air flow, leading to a more efficient chare
capacity. The minimum recommended tower height is 30 ft or 20 ft above nearby obstructions as
shown below.

6. MAINTENANCE
Your Sunforce Products 600 Watt Wind Turbine has been designed to run for long periods without
requiring any maintenance. Performance will be enhanced if you periodically inspect your system.
Review the following simple maintenance procedures and implement every six months.
Caution: Do not go near the wind turbine during operation.
Caution: The blades are sharp. Please handle with care.
• Check blades for superficial damage. Replace blades if damaged. It is important to not use blades
that are damaged, as you will lose overall balance, resulting in a decrease in efficiency. Should you
notice damage to the blades you must replace all 3. The blades are balanced as sets.
• Check the blade bolts and the hub nut for tightness.
• Check nosecone 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.
• Sunforce Products suggests replacing the blades every five years for optimal performance.
7. FAQS
(1) How does the Sunforce Products 600 Watt 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 Sunforce Products 600 Watt 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 150MPH upwards, please turn off the MPPT controller which will in turn manually apply the
braking system to protect from any over spin. Once the Turbine has stopped it is possible to lay down
the Tower to offer further protection.
(3) How long will the bearings or other wearing parts last?
According to engineering calculations, the bearings should have a 10-year 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 Sunforce Products 600 Watt Wind Turbine be connected in reverse-polarity to the battery
without causing any damage?

16
Reverse polarity will cause damage to both your MPPT controller and 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 Sunforce Products 600 Watt Wind Turbine to short-circuit the output?
No, the Sunforce Products 600 Watt Wind Turbine is designed to be short-circuited as a normal
shutdown procedure by a fuse. The function of the stop switch is to both disconnect the turbine from
the batteries as well as short-circuit the output of the turbine.
(6) Where can I locate tubing to make a tower?
Your Sunforce Products 600 Watt Wind Turbine is designed to make mounting as simple and
straightforward as possible. Should you not wish to purchase the custom tower kit feel free to utilize
schedule 40 1.5 inch steel tubing. This should be available through your local hardware outlet.
(7) What is the difference between copper and aluminum wire?
Generally aluminum wire is less conductive, so it must be bigger for the same amp load and resistive
losses as copper. Sunforce Products 600 Watt Wind Turbine uses copper or tinned copper for the
yaw wires.
(8) What battery should I choose for my Sunforce Products 600 Watt Wind Turbine?
There are multiple battery options in today’s market– flooded lead acid, absorbed Glass mat (AGM),
gel cell and NiCad. There is no definitive choice for your alternative energy needs. Normally the
choice of battery is determined by availability and pricing. Should you have questions regarding
batteries please consult a local battery supplier. Or view: www.batterycouncil.org. The capacity of
your battery bank is determined by your use. Below is a good guideline.
• 12-volt systems – 400 Amp-hours
• 24-volt systems – 200 Amp-hours

17
Possible Battery Configurations (suggested)
(9) Is lightning protection necessary?
You should ground your Sunforce Products 600 Watt Wind Turbine. Proper grounding (illustrated
below) provides protection to individuals and equipment by eliminating the possibility of dangerous
voltage. Remember a steel tower is a conduit for lightning.

18
Every wind turbine and turbine tower needs to be grounded at the tower base
even though the system may be grounded at the battery bank. Grounding the tower at its base may
help prevent shocks to persons touching the tower due to lightning or electrical faults.
Please take the time to review the National Electrical Code (NEC) and local
building and zoning regulations for complete requirements. Even in “Off Grid Systems”
there are multiple ways for tower grounding, the most common method is a copper clad steel
electrode(s) driven into the soil. Please view the following grounding diagram.
(10) What effect does radio interference have on my Sunforce Products 600 Watt Wind Turbine?
The internal circuitry of the Sunforce Products 600 Watt Wind Turbine is shielded and filtered to
prevent radio interference, and has been tested to insure electro-magnetic compatibility.
(11) What effect does my Sunforce Products 600 Watt Wind Turbine have on radio transmissions?
The Sunforce Products 600 Watt Wind Turbine normally does not affect radio transmitters. Care
should be taken, however, to route power lines from the Sunforce Products 600 Watt Wind Turbine
away from the power and antenna lines of a radio transmitter. An old ham radio operator’s trick is to
twist positive and negative wires together to provide an even distribution of EMF noise across both
wires, which serves to cancel out the electrical noise created. This technique can be used on the

19
Sunforce Products 600 Watt Wind Turbine power lines, on the radio’s power lines, and on
transmission wires. Transmission lines should always be kept as far from power lines as is practically
possible. Proper grounding of the Turbine and other system components must also be observed.
(12) Will it affect the regulation of my Sunforce Products 600 Watt Wind Turbine to install an RF
(radio frequency) filter?
An RF filter should not affect the regulation of the Turbine, but any electronic devices placed in line
with the turbine must be rated for the proper current and voltage. It is best to place any line filters on
the power lines for the load device that requires it, and as close to the device as possible.
Trouble shooting
You may require an extra person to assist with these tests.
1) Remove the blade/hub from the turbine. Replace the rotor hub nut on the rotor shaft.
2) Quickly spin the rotor shaft manually with your fingers while connecting and disconnecting the red
and black wires (turbine must not be connected to batteries).
3) With the red and black wires connected to each other, the shaft should be more difficult to turn.
When the wires are disconnected it should spin freely.
Should this not be true please contact supplier or Sunforce Products.
4) With your 600 Watt Wind Turbine connected to your battery bank, use an electric hand drill to spin
the rotor shaft.
5) Below 500 RPM, the rotor should spin freely without friction.
6) At 500 RPM and above, the Wind Turbine should be charging the battery. You should feel
resistance on the rotor shaft if the shaft is not rotating; contact your turbine dealer or Sunforce
Products. Be aware your battery banks needs to be under 12V or 24V for this testing as the Turbine
needs to read a charge.
