Can I add Turbine to Current Solar System?

It's really hard to find a Hybrid COntroller for both wind and solar. 
Current Solar system is 1550 Watt Kit. 
Winter is approaching, and would like to add Turbine. Instead of upgrading the controller, 
If I wanted to add Wind Turbine, Can I simply just wire the Wind Turbine to my Battery Bank along side with my Solar? 

Unless if you can direct me to a website that sells a Hybrid Controller for offgrid use that is able to handle 1500W Turbine and 1550 Watt Solar panels, that'd be Great!

    There are controllers such as the Morningstar TriStar  which can control solar or wind but not both at the same time. With wind it would be set up as a diversion controller to divert energy to a dump load when the batteries are fully charged to prevent turbine  over speed when there is no charging load, with solar there are no moving parts so there is no need to dump excess energy.

    Being that the requirements are vastly different I would think it's unlikely there's a controller that facilitates both similtaniously, though I may be wrong.

    When thinking about including wind to a system I would highly recommend researching the feasibility as it is a little more complicated and has specific requirements with regards to wind speed, obstructions height requirements and so forth. The cost of tower construction, additionalequipment and preventive maintenance for a wind generator, makes additional solar more attractive in most cases.

    What if I just leave my solar alone, and get a small Wind Turbine? Can I just add the turbine to the battery bank? 

    For example; 
    Solar remain the same but a new Turbine Charge controller wired into the battery bank in the same battery terminals that the solar charge controller is bolted to? is this possible?

    Yes it is possible with a separate diversion controller and dump load or other means of braking the turbine. The diversion controller will disconnect the turbine from the battery when they are fully charged and direct the turbine output to a dump load, as an example, there may other methods of control specific to the turbine used.

    Wind  turbines are really not a great idea because:
    they need Lots of wind
    Lots of maintenance (greasing bearings and brushes)
    a special controller to provide braking, to slow the blades down in high winds  or when batteries are full

    And they have to be quite high off the ground to get consistent air flow. Which pretty much means plunking them on some sort of lightning attracting difficult to get to for maintenance tower.

    Buy more panels.

All panels in parallel for a 24 volt system. Trace DR1524 MSW inverter which has performed flawlessly since 1994. Outback Flexmax 80 MPPT charge controller four 467A-h AGM batteries.
