This gives you an idea of the wind over a week - http://www.wunderground.com/history/air ... story.html
Not exact, because the weather station is merely nearby.
That shows you might not get 400W out of the turbine. The specs show 400W at 28mph meaning you would need 13 hours of that speed constant to charge those batteries. (check my math please) So bring a wagon to take batteries over to Snow Koan Solar for supplemental charging. Maybe bring a weather station and data logger to correlate wind over the week with power over the week.
You should ground it by burying a ground rod horizontal, say 18 inches down. You would need a mounting pole, say 20' and guy wires.
Bring it! Visit the AEZ and share/report on your experiences. Maybe add solar panels next year. The AEZ has a message board and may have some expert advice. In fact, the AEZ accepts all campers who apply in time.
