Product Description

The Sunforce 44444 400 Watt Wind Generator uses wind to generate power and run your appliances and electronics. Constructed from lightweight, weatherproof cast aluminum, this generator is also a great choice for powering pumps or charging batteries for large power demands. With a maximum power up to 400 watts or 27 amps, this device features a fully integrated regulator that automatically shuts down when the batteries are completely charged. The 44444 is virtually maintenance free with only two moving parts, and the carbon fiber composite blades ensure low wind noise while the patented high wind over speed technology guarantees a smooth, clean charge. 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. The 44444 uses a 12-volt battery (not included) and measures 27 x 44 x 44 inches (LxWxH)

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.

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.

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.
