I need plans for a 600W wind generator

 


I need a small wind power generator for a trailer camper. I think what
I am looking for is a permanent magnet alternator design. It will
supply power to run up to 500W of AC loads in the trailer through a
Schumacher 750 W inverter.  I'm figuring it is probably abt 85%
efficient, so that is 575 watts input power, so I rounded that off to
600 watts input.  It needs to keep a 12V 140 amp-hr deep cycle
batttery charged up, too, so we have a little power in our camper
during (very rare) times when the wind isn't blowing. I am a good
handyman and know electrical work, and so I really want to DIY such a
generator from plans, rather than buy it.  It would be ideal if I
could just buy the alternator itself and rig up the rest myself.

as you seem to be indicating, then it won't exactly be small. Ball
park, at least 8' in diameter. Even larger if your design isn't
efficient, low tower, etc.

From my limited experience I think you will need 8-10 foot diameter blades,
a 35 foot high tower, and consistent 30 mph winds to get 600 watts.
Hopefully someone else can give you a more optimistic point of view.

Many people use a few solar panels and a charge controller for what you want
to do but probably most use a small gasoline generator and a Smart Charger.
One of the most popular is the Honda eu2000.  Yamaha also makes a similar
inverter generator that has very good reviews.  If noise is not a problem,
and you are going to be running over half load most of the time you can get
a 2000 watt Chinese generator (UST etc) for a little over $200 that, IMHO,
is far superior to many other small generators costing 2-3 times as much.  I
have a 2000 watt UST 2300 that is not very loud, is good on gas, and the
only problem I had with it was a broken muffler which they replaced under
warranty.  It has about 2400 hours on it.  I only paid about $190 for it 1
1/2 years ago.

Another option would be to build a battery charger using a car alternator
and a small engine (3-5 HP).  In spite of what you may read in my opinion
you need to bypass the internal voltage regulator and adjust the voltage
manually or your deep cycle battery will not last very long.  You need to
achieve 14.5 to 15 volts depending upon the manufacturer's recommendations
and occasionally run it for 1/2 hour or so at 15-15.5 volts for
equalization.
