Marine Turbine for Wind Power at Sea!

Marine Turbine

This Marine Turbine is high power and self-regulating, going into a silent stall mode in high winds and stopping any charging when the batteries are full.
This marine turbine is specially reinforced to weather harsh environments in open sea or on the shore. Included MPPT charge controller optimizes charging for longest life and best efficiency!

Frequently Answered Questions

1. How does this Marine Turbine operate in high winds?

This Micro Wind Turbine’s operation will be halted to reduce the risk of damage due to overcharge and over spin 15 of the rotor blades. This process of braking is handled internally through your Turbines electronics.

2. What is the maximum wind speed this marine turbine can withstand, and what if there is a storm?

Your marine 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 exceptionally adverse conditions and 10 years in normal conditions.

4. Can the Marine Turbine be connected in reverse-polarity to the battery without causing any damage?

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 Marine 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. What about a Mounting Tower?

This 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. This Wind Turbine uses copper and tinned copper for the yaw wires.

8. Which battery should I choose?

There are many battery options that will work, and this turbine will charge both 24V or 12V systems. OM recommends AGM Batteries because of their durable longevity, lack of maintenance, and additional safety and environmental benefits.

9. Is my Marine Wind Turbine really protected from salt corrosion?

Yes! All components have been rigorously tested to perform under marine conditions.

10. Is lightning protection necessary?

Yes, proper grounding provides protection to individuals and equipment by eliminating the possibility of dangerous voltage. Remember a steel tower is a conduit for lightning. 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.

11. What about radio interference?

The internal circuitry is shielded and filtered to prevent radio interference, and has been tested to insure electro-magnetic compatibility. The wind turbine normally does not affect radio transmitters. Care should be taken, however, to route power lines from the Marine 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 Marine 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 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.
