Wind Generator Charge Controller

I built a wind generator using a 180v 8 amp 1725 rpm pmdc motor where I have been able to achieve anywhere from 30 vdc to 120vdc unloaded depending on which rotor I am using.

the problem is when I am connected to the batteries I...

A good charge controller includes a DC-Dc converter which changes your output voltage to that best suitable for charging the battery. It's second purpose is to control the current to the battery to avoid overcharging it.

But you may...

www.mwands.com this is our new wind and solar charge controller with built in divert load.also a fix for slow startup chinese made wind turbines ...

I have an ~18v solar panel and a ~15v wind turbine. Sometimes one generates more voltage than the other. How would I get both of them to charge one ~12v battery? I can't just connect them in parallel with diodes, because in that case, only the higher

Placing diodes in series with each source to the battery would solve your problem. You should use a charge controller on the system to prevent overcharging the battery.
I've put together a relatively simple dump load circuit which diverts...

I was researching wind generators, and I kept reading something about wind generators needing a big battery bank (300-400 Ah) or a charge controller with a dump or power diversion mode to maintain a draw on the generator at all times.

Some wind generators will overspeed if they don't have a load.  Even if they don't, using a charge controller with a dump load lets you use energy that would otherwise be wasted; even if the use doesn't gain you much, it's better than not having the

I am looking for some good information on setting up a system that uses solar panels and a wind generator. My basic question is with the charge controller. Can I regulate the charging from both sources using the same charge controller? I'm looking

Usually one would use either solar or wind, but not both. If you have good wind, it will be cheaper than photovoltaic.

I don't know if there is such a dual-input controller as you're looking for. You might try asking on the NAWS...

I am in the process of building an array of solar panels and a wind generator. when I am done with the first phase I will have a 12 volt wind generator, and 3 18 volt 8 amp solar panels. the inverter that I was looking at is a 48 volt inverter...

If it was me i would use a 12 volt regulator then put 10amp diodes on each battery charging line so they couldn't feed into each other. Then you could still use the 48 volt for what ever you need.

What are you doing to do with 48 volts

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...

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...
