About Wind Power

Wind generators convert the mechanical energy of their spinning blades into an electric current; they do not actually store power. Sunforce Wind Generators are primarily used to recharge all types of 12/24 Volt batteries, including lead-acid automotive batteries, deep-cycle (traction type) batteries, gel-cell batteries, and heavy-duty (stationary type) batteries. When using this wind generator to run appliances on a regular basis, the use of deep-cycle marine batteries is recommended. This type of battery is designed to withstand the frequent charge and discharge cycles associated with wind power use. Attempting to run the wind generator on an open circuit without a battery may cause damage to the generator or connected equipment.

The included Maximum Power Point Tracking (MPPT) charge controller enables the 600 watt land turbine to achieve its highest possible performance by periodically tracking the maximum power point of the turbine’s output. The MPPT can be used with battery systems of either 12v or 24v DC. Its features include 12 / 24 volt automatic detection system, temperature-compensated and three-stage charge regulation, fully waterproof design, inline 40 amp fuse, and a manual/automatic braking system.

Technical Specifications
  • Power Output: 450 Watt at 12V (Max 450W) / 500 Watt at 24V (Max 600W)
  • Charge Voltage: 12V / 24V (auto detect)
  • Input Voltage: 5 - 75 Volts AC
  • Efficiency: >97-99%
  • Battery Type: 12V / 24Volt

I purchased this windmill to augment a solar panel I use to charge a 12 volt battery bank. I have a solar powered well system for watering cattle, and the solar was not keeping up during times of low light. I intend for this unit to be an augment to my current system, not the only source of electrical current. I purchased this unit because it was 200 more watts output than the most popular sun force mill, but I was sort of disappointed that it is not made in USA like the 400 watt model. It is made in Taiwan. I guess this is ok, as Taiwan is an ally of the USA, so at least it was not made in PRC.

The package arrived quickly, and everything was in order and exactly as described. I assembled the unit in just under 30 minutes. There was an extra set of screws, nuts, and bolts included, and this could be handy for fumble fingers like myself. The fasteners are of good quality, and they were all present and accounted for. I did not have to use any of the extras (yet). Also included is a electro brake switch which I am not planning on using.

I first tried to mount the mill on a 21 foot piece of chain link fence top-rail, but it buckled over in the middle. I opted for a heavy piece of tubing from the chain link fence wholesaler, and it works great. I used #10 SOJ cable for my electrical connections. The mill started turning even before I had it hoisted all the way up, and it makes a pleasant enough sound as it turns. There is some small noticeable vibrations that may be due to a small imbalance in the rotor blades or something, but nothing that seems detrimental to the mill.

I made all the electrical connections without any trouble.

The "Product Features" summary incorrectly states that it starts to "operate" at 4 mph, implying it's producing power. If you read the manual, there is a diagram that shows the turbine starts producing at 4 m/s - that's 4 meters per second, or about 9 mph, and then the power production is small. It does not produce 600W until you get up to about 30mph. That's a **lot** of wind!

I bought this from Fry's electronics years ago. i installed this after a lot of effort. it really is hard to get something that high and stable at the same time. I suggest that you set up the pole first before you buy the turbine. Finally, after many tech support emails later, i could only get a trickle of a charge. After everything looked good, Sunforce said that i did not have enough wind! I found that was not true, because I tested it blowing as fast as possible, and I still get the same trickle charge. i'm just too tired of spending more time and effort on this turbine. It is now way past the return period, and it would be hard to prove that their product is defective in small claims since i'm not an engineer. I don't buy any sunforce products now. Neither should you. Also, i suggest that you try to turn the turbine with a drill first to see if you get a charge before installing. I should have done this first myself.

I received mine in the mail free shipping from amazon in 4 days and i live here in Kodiak Alaska.I bought the 30 ft tower kit for it , but only used 17 ft of it, for now. I plugged it into my power hub plus 1800 solar generator on earth day. Putting together the turbine was basic easy and fast. The tower was easy to put up,doing the wires for the tower was easy once i figured out how to put it up by myself,it can be done. Today i put up near the tower a acu rite wind speed and direction wireless weather station. The extra power i get from wind power is Very noticeable.I have 4 solar panels that come with the gen set to charge the 4 100 amp hr batteries. Seeing power go into the batteries after daytime is a nice change. The wind we have had since i put it up...about 25 mph or so ,,, tells me i made a good choice .Winter months my solar is sip so i might even get another turbine and use the other half of the tower.. on the next good windy day ill put up a video on my you tube channel .

This turbine was used to power a remote seismic installation in Southern Wyoming. It was installed on April 6th.

It's pretty windy in Southern Wyoming, with gusts on an average day around 30 - 35 mph. At this wind speed, we saw a maximum of ~ 20Amps output at 14.5V. That's a little under 300 Watts. The average output was ~ 8 Amps, or 120W. To be fair, that doesn't take into account losses in converion to DC, and the battery bank was close to full capacity, so this may have been the controller regulating the voltage.

One odd thing the controller seems to do is apply the brake automatically when the battery bank is fully charged. This is understandable if the goal is to preserve the bearings and such. However, it creates increased stress on the blades. Much of the wind force on the blades is converted to rotational energy normally... which leads well into the next event.

On April 9th, there was a storm that rolled through the area. Max sustained wind speeds were 49mph, with gusts up to 66mph. This turbine is rated for gusts up to 115mph. The storm ripped all 3 blades off the rotor; severing some cables in our installation in the process.

I was a little worried that the output would be insufficient to power the installation; however, this was a much worse outcome, and I'm quite disappointed in the turbine. It did not output as advertised, and did not stand up to stronger winds as advertised. As other reviews have said, this seems to be a toy, and not a robust piece of reliable equipment; it lasted 3 days.
