New guy that regrets buying an air 30 and not another air x

I am new to this forum, live at 2700' elevation in Hawaii, high desert. I run two houses on wind and solar, had two air x turbines, burnt on up with 78 mph winds, had voltage set to high. So I replaced it with the latest and greatest, the air 30, did not know the wimpy thing shuts down when wind gust over 30 mph. This is a problem because I have winds over 30 all summer long, I have been told there is nothing I can do to raise the feather speed, is there? I have it hooked up directly to the batteries, 48 volt system, 405 amps, with the stop switch, through a 15 amp curcuit breaker, would it be better to run it through a fuse? Or maybe I can lower it to 10' off the ground, it is 30' now. Or if I turn the max volts up, set at factory specs 54.4 will go to 68.0. By the way the 7 year old air X is still putting out in 40 plus winds. Frustrated
