<div class="moz-cite-prefix">We've done some research on this, as
we're doing an XL.1 project at 12 v right now. <br>
I don't have first hand experience with the Clipper yet, but I
have over a decade of XL.1 experience and many years with
Midnite's electronics. The Clipper is exactly what is needed. It
also moves the rectifier down to the ground, and offers a braking
disconnect system to shut the turbine down completely if needed.
<br>
The Classic by itself isn't really controlling the turbine speed,
and counting on the XL,1 mechanical governing design by itself is
definitely full hardy.<br>
Unfortunately, Bergey's new staff is not really up to full speed
yet on what is needed to make their turbines work long term. At
least they've abandoned the old XL.1 controller. Hopefully the
turbine itself hasn't changed too much; I've seen them survive
some very high speed winds and direct lightning strikes.<br>
