We've done some research on this, as we're doing an XL.1 project at 12 v
right now.
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.
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.
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.

Hello Wrenches:
We have a customer who's got one of the Excel One wind gennies, and
he's burnt up two Classic controllers (overvoltage....the 2nd time it
got over 400V before it burnt up). Bergey's been dragging their feet
as to why this is happening; they're saying it's probably an "upslope
site" where the RPM just gets too high, among other things. Metering
tests prove that the stator is OK.
They also said that Midnite Solar has a 'clipper' to prevent
overvoltage; do any of you have any experience with this device? It's
~$1200, and of course there is no mention of this on Bergey's web site
or in their XL.1 manual.
I have several other XL.1s in the general area, but they are on their
old 24V controller. So I am looking for more information on anyone
who's using this 'clipper'.
Please feel free to contact me off list.
Thanks!
