Product Description

Amazon.com

The Sunforce 44444 12-Volt 400-Watt Wind Generator harnesses the power of the wind to provide you with clean, free renewable energy. Not only can it lower your electric bill at home, but it's also a great choice for generating electricity at cabins and worksites far from existing power lines. With compatible equipment, Sunforce wind generators can even be paired with solar panels for additional, diversified power creation.


Sunforce wind generators are easy to set up and operate.
Convenient Power That Helps You Save Money and Protect the Environment
On land and at sea, people have been harnessing the power of the wind for thousands of years. With the Sunforce 44444 12-Volt 400-Watt Wind Generator, you can use the power of the wind to provide energy for your home, cabin, worksite or remote equipment. Wind power can help cut your energy bills by reducing your dependence on the main electrical grid at home, and is also ideal for many remote locations that are far from existing power lines. Unlike nuclear and fossil fuels, wind power systems are clean and pollution-free, and they require little maintenance to operate.


Wind power can significantly lower your electric bill.
Flexible Power for New or Existing Systems
The Sunforce 44444 12-Volt 400-Watt Wind Generator is an ideal addition to many new and existing renewable power systems. It provides up to 400 Watts or 27 Amps of power at maximum efficiency. The fully integrated regulator automatically shuts the unit down when the batteries are charged to minimize wear.

The Sunforce 44444 12-Volt 400-Watt Wind Generator features a durable aluminum body and lightweight carbon fiber blades that are optimized for maximum efficiency and low noise. It is completely weatherproof, and the patented high-wind over-speed technology keeps the unit safe in high wind and stormy conditions. Assembly is required, but this generator installs easily and mounts to any sturdy pole, building, or the Sunforce 44455 Wind Generator 30-Foot Tower Kit.

About Wind Power
The Sunforce 44444 12-Volt 400-Watt Wind Generator can provide an average monthly output of 38 kilowatt hours with an average 12 mile-per-hour wind speed. It requires an 8 mile-per-hour wind speed to start generating power. As the local wind speed increases, so does the power output. Since this type of generator uses wind as "fuel", it is important to choose an appropriate site. The ideal location for a wind generator is 20 feet above any surrounding object within a 250-foot radius. Wind speed increases with height above ground, so a taller mast can provide significant gains in energy production.

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-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.

This does charge batteries, but only during lots of wind.
TMCLEN
I have a theory as to why this will fix them, but I think if it's not well grounded, it would for sure ruin it!
Kellie Conn
As a primary alternate energy source however, solar is better.

First of all, this wind generator's output is preset to 14.1 volts (for charging batteries, you know. The preset can be adjusted from 13 to 17 volts, by the way). 14.1 volts divided into 400 watts is 28 amps, so the specs are correct as stated in the product description. Remember to always keep in mind the differences between 120 volt AC current and 12 to 14 volt DC current -- it's really important on this alternative energy stuff.

Naturally, you are only going to get close to the 400-watt maximum output with a steady 28 mph wind. But the unit won't "go up in smoke" at that point as some reviewer said -- all wind turbines have built in cut-out system that prevent them from going over their rated output and being damanged. C'mon, folks... the people who make these things are not dummies.

But it's true that there are not many places in the world where you get 28 mph winds blowing on a regular, continuous basis. The suggestion of other reviewers to figure on getting maybe a 15 mph average wind speed with output from the wind generator of 50 to 60 watts at 2 to 3 amps is a realistic evaluation of what most people can expect out this or any other small wind turbine on a fairly regular basis. On days when you've got more wind, you luck out and get more power is all.

That's why, for most people, the first alternative power choice is amorphous solar panels (they continue to work on cloudy days and with partial shade) because you can rely on the sun on a day to day basis more than you can on having a good steady wind consistently. The manual for this product states that the blades should start turning in a 7 mph wind, which is just a good breeze.

I have this wind generator hooked up to
8 6 volt deep cycle batteries powering my 2 bedroom
off grid home. we run 2 televisions dvd players and compact
flourescent lights for bedrooms and kitchen without
having to turn on our generator. We dont have a microwave,
and our refrigerator runs on propane. But after using our loud
generator for 2 months at $15.00 for gas on a daily basis, The machine
will pay for itself quickly, The noise is minimal.The sounds it makes reminds me of birds chirping. You could not use it to run vacum cleaners
washer dryers and things like that but if you need a little energy for
lighting and small appliances this wind generator is great.

I installed this unit to reduce the use of my generator for my off-grid RV. The power output is so insignificant that it will never pay for itself. Unless you live in an area with non-stop 20/25 mph wind, it will never do the job. Think of how long it takes a 2-amp trickle charger to bring a battery up to full charge. This puts out less than 2 amps on a windy day. I purchased a Kyocera Solar KC130TM - 12 Volt, 130 Watt Solar Panel With Junction Box. The solar panel had an immediate impact on my bank of batteries. I watched my battery bank go from 12.1 volts to 12.9 volts in less than an hour. The cost of the solar panel and charge controller was less than half of the wind generator/tower combination with a much higher life expectency.

Verified Purchase
6 years ago, I bought my first Air-X ( that's the model with the Southwest Windpower brand on it, this is their product) which ran for 2 years, then had a minor failure, fixed under warranty. It then lasted about a year, and the circuit board failed yet again. Again, it was warranted. The next failure, however, was not. So, I bought a kit from SWWP to "update" the turbine to the new "Air Breeze". That lasted 2 months, and it utterly melted down inside. It was a toxic swamp of caustic material from the insulation and other materials inside, which had gotten hot.

That was fixed under warranty and lasted ... a month. Then, I bought one of these. It was installed temporarily for about 4 months, and then moved to replace the dead Air Breeze (failed yet again, 3rd time). It lasted a month, and it too, melted down inside. Yes, the same location, the same load, the same everything the original one made 3 years without major issue, has now been through 4 rebuilds in a year and a half. In fact, I have had no significant use ANY of the generators since the original Air Breeze conversion. They have either sent me parts, or replacement generators (takes up to 2 months to get warranty fixes) and every one of them has failed the first time any significant weather system has come through. The Sunforce branded model worked through 4 months in a semi-sheltered area, and weathered ONE storm. It was taken down, stored for 2 months, and reinstalled in the original location for my first Air-x, and it died when the first rainstorm came through, as it melted down and the insulation or whatever it is, is literally dripping out the bottom of the unit, which is still on the tower. I'm not taking it down until I figure out what to do with it.

We have been involved with this product from the mid 90's. Initially the manufacturer (Southwest Windpower) had potted regulators inside the nifty cast aluminum housing on their 303 wind-machines. After installation the machine ran great (except for the unbelievable noise from the blades) for about 2 weeks until the uncooled regulator overheated and self destructed. We were living off the grid in a very remote part of Samoa at the time and literally depended on the output from our wind turbines and solar panels. We had a lot of experience with older types of permanent magnet wind generators and spruce (wood) blades. Our older Redwing generators never gave us any trouble except for the necessity to periodically replace the brushes. Southwest Windpower was contacted after our early debacle and this was the beginning of many overseas phone calls and 99 email correspondence over 4 years, fighting with them to stand behind their product and do some actual real world testing of their product. These people had a great idea but the bugs were not worked out and we were their unwitting test subjects. Jay Yaeger, Dave Snowberg, Sean Hickey: all Southwest Windpower muckety mucks get a big thumbs down for their lack of followup and support.
Initially Southwest Windpower was coerced into sending us replacement parts. Later after much wrangling we did mange to have the company send us updated versions/replacement machines. Many, many hours of troubleshooting for them, pulling wires, dismantling our installation, re-installation...etc. We installed these and guess what : more overheating and failures. In one long distance telephone conversation with Jay Yaeger at Southwest Windpower I asked him if they did any wind tunnel testing to be certain these machines would stand up to hours and hours of use.
