Here's the TR-10 prototype shot as a small front moved through SW Idaho. Average wind speeds at the time this was taken were around 15 MPH. Rotor speed was around 70 RPM, producing around 150 - 200W.

Blackhawk TR-10: In this video you see the battery level starting off at 27.9V and quickly climbing to 31.0V as the wind picks up. Wind averaged over the past minute shows 15.7 MPH. The amps going into the battery start off at 3.86A and peak at 7.75A.
Although the battery is 24V, short bursts of charging power like this do not damage it as long as they are not sustained. In normal use the charge controller would automatically dump the excess power to a diversion load, without radically changing the load on the turbine head.
