Wind Generators Homemade
Do I need a charge controller or not? I'm confused. Again.?
Hello, I'm in the process of building a homemade wind turbine and I'm trying to figure out if I need a charge controller or not. Some places say I do and others say I don't. The turbine has 2 treadmill motors that will be used as generators. Each individual motor is rated at 260VDC, 5A and 5100RPM. I have the turbine geared to a 4:1 ratio. Turning the motors 4 times faster than the blades. Rotor diameter is around 10.5 feet. At this time my battery bank is only rated at 95Ah at 12VDC I will be adding to this battery bank in the near future. My next upgrade will take the battery bank to around 380Ah capacity. I'm only running my small workshop off this so far. I'd like to include some of my house in time but that will be down the road a ways yet. I hope that's enough info for my question. If not just let me know and I'll get the anything more than is needed. Thanks for your time and help.
I've designed a charge controller for my wind system. It uses a bank of 1 ohm 225 watt resistors. The voltage applied to each resistor is controlled by a 2N3055 transistor. In this manner dump load current is controlled, creating a higher load when the generator voltage attempts to exceed the preset maximum. At lower voltages the transistors are turned off entirely.
