Heed Woof's advice on the turbine.. you will have a problem if it has no electrical load to keep it's speed under control. It needs to be loaded under most any normal circumstance.
Secondly on the load control,
Do NOT use a load control between the batteries and inverter. The inverter will only draw from them when needed anyway. On Xantrex equipment in that power range every necessary function for the inverter battery interface is all done in software.
You stated you contacted Xantrex to ask this, but did not state what advice they gave. I imagine it was something along the lines of "That application is not covered under warranty" and there would be a reason for that!
Thirdly, the inverter does not contain a charge control for any charging source per se, what it does have is a battery charger to charge from ether the utility grid or a backup generator.
This seems to be an extension of one of your earlier posts http://www.fieldlines.com/story/2007/12/16/155529/12
Where people gave you some information on charge controllers already.. re-read it.
If you still can not get a picture in your mind look for drawings of these types of systems.
www.homepower.com
Would be a good place to start for very GOOD system schematics that would give you a feel for the equipment your working with. Mind the schematics may not be your exact situation however you will start to see the similarities.
Short of that you could have a Xantrex engineer fax or email you their recommended connection practices in schematic form for your application.
You have gotten lots of explanation from folks here but a visual aid may be in order so have a look at HomePower. The subscription is worth it, in fact get some back issues. They come in print and digital.
