It's really old, never seen one like it. And probably yes, it is a 32 V.

My mother tongue is not English, so sometimes do not explain myself very well.

Well, my wife is Swedish and for 28 years whenever she gets mad at me she switches to Swedish when reading me the riot act. So I am very familiar with the mother tongue is not English situation

If you have an opportunity, please take a photo of the turbine and post it. Maybe I can identify it.

Aerogenerator questions

Dear Chris,

It's really old, never seen one like it. And probably yes, it is a 32 V.

I have not much experience with aerogenerators, so I am a little bit scared, don't wat to mess it up.

Trying to read all the info can be found in internet and in this forum, to learn from the "old" wise guys.

My mother tongue is not English, so sometimes do not explain myself very well.

Thanks again,

[ChrisOlson]

Have just repaired an old aerogenerator, it was in an old farm that a friend of mine has purchased.

What kind of a turbine is it? It is an old Wincharger? Most of those were 32V if it is.

Aerogenerator questions

Dear Mike and Naptown,

Well, the aerogenerator was there, unable to spin, now it spins, we have painted it, and if we can get some good watts from it, we will power a little outdoor 5 W led light at night, with a movement sensor.

Thanks for the info about Morningstar, will read the manual and see if we can get one unit.

Regarding the shortcircuit, it was not a really windy day; I thought it was a good idea to make a shortcircuit, to see if the aerogenerator was slowed down, and to see if there was some current flowing. But you are right, it's like trying to stop something moving in 0 seconds, this can not be good at all.

When we have the charge controller, will measure the volts amps and watts with a microcontroller and a SD card. If it is posible to attach graphs here will do so, and your points of view will help me to understand how the generator is performing.

Thanks again for the answers I get from you all.

Shorting it was probably not a good idea. Ok with solar panels not so good with generators run a load instead.
How hard was the wind blowing when you tested it

Nice on restoring a early (and fairly reliable) wind generator. 24V @ 1 A = 24 watts, which is not much, even if it cranked out 3A, that would be less than 75 watts. I think something is still wrong inside.

But, Morningstar makes a small MPPT charge controller, which is quite efficient, and will convert 95% of your 30V power, to 12V for battery charging. PWM style controllers will only harvest about 40% of that same power, but they cost a lot less.

Dear all,

Have just repaired an old aerogenerator, it was in an old farm that a friend of mine has purchased.

We are trying to use it for charging batteries.

Have measured the open circuit voltage and it gos to +30 Vdc ( it has only two output wires).

When the aerogenerator was spinning we made a shortcircuit, we saw a little spark, and the amp meter readed 1 amp, so we think there will be amp flow from the aerogenerator. Also the aerogenerator stopped nearly inmediately, matter that we think it is correct.

In the aerogenerator the only info found is 3 Amps.

We think it is a 24 Vdc 3 Amps generator, it is very little.

Now the question is, which kind of reliable regulator can I purchase to charge 2 12 Vdc batteries to 24 Vdc?

And another question, is, it is enough to make a shortcircuit test to ensure that the aerogenerator will generate amps?

Thanks a lot for the info.

Regards,
