i have a 2.4kw solar setup with a hybrid inverter plus x4 2.5kw battery , i am looking at a 1kw wind turbine with a mppt controller but with out going too tech can i wire it all up direct to the battery or do i need some sort of ffancy setup , i want to keep it as simple as possible , i am looking at this
 
You need a different charge controller, charging the same battery. The type of controller is different too.

There are hybrid systems that do all-in-one, but the principle of 2 controllers needed remains.
 
i was hoping things had got more simple, maybe further down the line , i might remove one battery from the solar setup during the winter and use that as a stand alone system for now as paying out for another 6kw controller is not possible at the moment
 
Most of the smaller cheap wind turbines are basically useless unless you have a lot of steady strong wind. Are you on a coast or in a valley? Search review videos on the unit you are thinking about and see if anyone has had any luck making power with it. The best I have seen is getting under 100 watts from a 1,000 watt rated wind turbine. There is one video about installing one on a lighthouse with a lot of wind, but they didn't show any production numbers.

Most wind turbines are also a 3 phase AC output. So you need to run it through a rectifier bridge and then into an MPPT charge controller. And a charge controller for a wind turbine should also have a dump load. This is a large resistor that will pull a lot of current to load down the turbine to keep it from spinning wild if the wind is strong and the battery is full.

Be sure to check the specs on any MPPT unit to make sure it can run a wind turbine properly.
 
thanks i did read about many being over estimated in output , i am on a hill be it small about 1/4 mile we do get a good breeze , the more i read the more it seems to be not cost effective, and during the summer wont be needed as the solar does the job just fine
