Yes, you may be able to use a MidNite Solar Combiner Box in a wind application depending on the wind turbine's manufacturer's specifications.

In other words, if you are pairing a wind turbine with a MidNite Solar CLASSIC Charge Controller, you can only pair one wind turbine per CLASSIC controller, so a combiner box may not make sense to use.

If you are pairing multiple wind turbines with a built-in charge controller (for example the Primus Wind Power wind turbines), then in this scenario you may be able to use a combiner box, however, you should contact the wind turbine manufacturer for any specific recommendations or requirements.

You can use a MidNite Solar Combiner Box for any DC power source as long as you use DC circuit breakers.
