Those are great early results.
As I said before, you're on the path to success so what I'm really concerned about is not being ready to harness that success.
My intuition is that you were told to do something that you should not do with that charge controller. The likelihood of a disconnect that coincides with strong wind is very high - almost guaranteed - meaning that I hope you can deal with this quickly.
Can you tell me more about your charge controller and why it has any business disconnecting your turbine?
Make, model, how it's connected?
FYI, my system is typical of a battery-charge system, where the output of the generator is rectified from 3-phase AC to DC, then directly connected to the batteries. For battery charge control I use a controller in diversion mode only. It will discharge excess energy through a resistor bank but only when the batteries are fully charged and don't need extra. Shut down is accomplished with a manual switch which shorts the AC leads. I don't use the shut-down switch very often.
The whole idea of permitting the charge controller to disconnect the generator only works when using solar panels.
The vibration will not go away until you make the arms to the blades more rigid with a diagonal strut.
The noise can come from any moving components, not just blades. If the strut tubes are round, if the blade tips are rough, if the fittings have bolts sticking out, they all shed a vortex.
IMO the noise is a low priority. You don't seem to have a lot of neighbours... just sayin'...
