Wind Power Generators

DIY homebuilt wind generators have a lot of advantages in cost and therefore are easier for a backyard mechanical type to get into residential windpower. Some of the drawbacks to building your own, however, are trial and error type learning experiences. One such experience could be that you will learn all about overspeeding caused by excessive amounts of wind. High winds can literaly tear your unit apart in short order. This means every system should have some method to slow the blades down and protect the mechanism from harm.

One method used is to place a load on the system by using up power with an electric heater or whatnot. This makes the system work harder and resistance will keep it from spinning as fast. Still, this can burn out your alternator and leave the system wide open to overspeeding out of control. More protection thn this may be necessary.

A better design feature is to have some method of the blades automatically turning out of the wind if speeds become too high or the load on the unit is too small for the electricity being generated. You can’t keep an eye on everthing in person 24 hours a day, so it is the best bet to build in some sort of failsafe to protect it. This would be installed right on the wind generator tower.

On huge commercial wind farm generators, a computer senses the wind speeds and using an electric motor, turns the entire mechanism slightly to the side. Smaller systems such as a do it yourself homebuilt wind generator usually are equiped with an offset rotor and tail stabilizer, which will turn to one side if blown on hard enough. Others are spring loaded, and tip backwards if the wind is strong enough. These ones return to the ready position as soon as the pressure abates, due to a weight mounted in front.

A very important part to every homemade wind power generator is the electrical storage capacity of its battery bank. No matter how much power your system cranks out when the wind is blowing strong, there will always be calm periods where the turbine cuts out. This is when the inverter can suck your batteries dry if he storage capacity isn’t big enough.
Power generated from solar panels and homebuilt wind generators can be stored in a deep-cycle battery bank until you need to use it. A good rule of thumb is that your battery storage capacity should be two to four times your daily power requirements.Then you will have enough power if it becomes overcast or the atmosphere is very calm. To keep the system functioning well and to prolong the lifespan of hte batteries, they should be located in a warm building (25°C is best) but away from direct heat sources. .
Good ventilation as well as plenty of room to make repairs or adjustments is a vert good idea.
What is the difference between a deeep cell or RV battery and he one in your car? Good questioin. Automotive batteries are made to give you a quick shot of electricity for starting a cold motor. This is different form an RV battery, which is designed to provide long lasting power. Properly maintained deep-cycle batteries are made for discharging hundreds of times during their life. A deep-cycle battery bank has several batteries all wired together to provide greater capacity and higher voltages.
The entire bank of batteries directs power to an inverter which converts DC power to AC for household use. A properly functioning charge controller may be attached to the homebuilt windpower generator system to prevent overcharging the systrm and wrecking any of your batteries.
