Question: Homemade wind turbine, 12v to 120v inverter..need help plz ^_^?

Ok i plan to make a wind turbine for a off grid hunting cabin so i can have electricity! i plan on hooking up the turbine generator to 12v car batteries 2 or 3 or 4...then use a 120v inverter...does this mean i have 120v of power or no? could i power a 110v fridge from this set up? and lastly if i add more batteries 12v...does that increase to 24v 36v etc...? or does it still have a 12v current? thanx in advance for any help...i plan to make something similar to this to give you guys an idea!! http:/ / www.mdpub.com/ Wind_Turbine/ index.html thanx for your response....an alernator from a car will not work as it requires a very high rpm to charge the batteries that a wind turbine is incapable of.... but on the other hand the led lights is a very good idea as they require less energy and have a 10 year lifespan...thanx allot for your help both of you guys answered allot of questions i had and also supplied extra insight...and i would hate to choose a best answer here so if you dont mind i will let the community choose..ok thanx for everything guys

>could i power a 110v fridge from this set up? No. Way too small of a system to do that. >to 12v car batteries 2 or 3 or 4 Car batteries are terrible for this application. You need batteries designed for "deep cycle " usage. >if i add more batteries 12v...does that increase to 24v 36v etc...? That depends on how you wire them! >or does it still have a 12v current? The words "12v current " don't make any sense. >then use a 120v inverter...does this mean i have 120v of power or no? As long as you supply it with the correct voltage & current input and don't overload it. >i plan to make something similar to this to give you guys an idea!! - His system only has enough power to run a laptop & a few low power lights. - He built his charge controller from spare parts he had laying around. This should tell you something about how much he knows about electronics compared to you. There is plenty of information on the Internet about wind powered generators. You need educate yourself a great deal more before you try to build a generating system out of surplus parts.

The simplest system would be a big 120A alternator from a car (police, ambulance), then charge a bank of batteries. In the cabin, run lights off 12V LEDs, if you need 110V, use an inverter. This system will work, you cannot use a lot of power, but since it is a hunting cabin, you do not need a lot of power. additional: Think RV. RV fridge runs on gas or electric. You CAN get the RPMs out of a wind mill, requires a system of gears or pullys. Think RV. RV solar panels will keep batteries charged. Think RV. RV's do not use car batteries for the "house battery ". Car batteries are made for heavy discharge, but not for sustained discharge. You need AGM or deep cycle. Trojan 105 would work. They are 6V each, but a pair of them will out perform any 12v battery.
