12 volt turbine with 24 volt battery bank?

[mroy0404]

Hi Guys

A friend of mine is looking into a 12 volt turbine,  he wants to wire it in with a solar array to help charge his batteries. The question is, the battery bank is a 24 volt set up. What kind of equipment is needed to wire the turbine into his set up?

Thanks for your into guys.

I assume the solar array is 24 volt .
 That being the case any large voltage rise is going to affect that controller .An Mppt will work the added voltage into a Buck or you can just whip up a bucking circuit and series the 12 volt genset in .
You can post the devices in use and get a more complete idea of the possibilities .

Why not get a 24V turbine?  They're nearly as easy to find.  If you have to use 12V you could just 'tap' the bank at 12V for the turbine, then use an equalizer to balance the two 'halves'. We've had good luck with the "autotransformers" made by Solar Converters. They're Canadian.

Good luck,

Far too little information to help much. Running a simple 12v turbine on 24v will result in it having to run twice as fast. the low wind performance will be near nothing but it might perform better in high winds as long as it is small enough not to damage the blades.

If it has any form of controller ( such as air X ) it wont work.

If it is small simple direct charging machine it may work in a good wind area. If you can produce a boost converter you may even get it to work very well but that is for someone who understands things.

Under no circumstances should the wind output be combined directly with the solar, the wind needs to be rectified straight to the battery so you can treat them as separate systems.

As already stated "why can't he use a 24v turbine and settle for an easy life"?

I'm going to take a guess that this is for a Marine install . In this case you should keep a eye on a uniform charging and don't do more than standardize for safety of shore .
  A DC output from a 12 volt charger is fine in serial to the Solar But the controller has to be able to respond to voltage in effective charge range of the Two . It's a good guess that you have a serial connected Panels . You may be able to parallel the panels and let the Wind generator do the charging .  Remember the Max charging will be limited to the solar amp rate . Some series Parallel disconnects could give you the wind when under way and solar as the norm .
