Ryan had some good information to add here.

> I agree Bergey missed the mark by not advertising a Clipper upgrade. 
> It will keep the investment safe as well as save wear and tear on the 
> turbine. The Bergey however was designed to not exceed a tolerable 
> voltage level for the Classic 250 and this is the first case of over 
> voltage damage. It could be anything causing the extra voltage. Some 
> speculations are updraft etc or it could even be a slightly different 
> characteristic in the blade makeup.

> At the end of the day the marketing department could have offered a 
> "Clipper Upgrade" and at the time of purchase it would not have been a 
> big additional expense as the Clipper replaces the Turbine control 
> box. This could have been marketed towards customers looking for less 
> noise out of the turbine or in extremely good wind sites as a safety 
> device.

> Something else to keep in mind that Bergey does not advertise is they 
> have a lower voltage 3 phase stator called the 24MS (This is not the 
> old 24 volt stator it is significantly higher voltage) that can be 
> very useful. As of right now they only suggest the Classic 250 with 
> the Bergey XL1 but in reality if you are doing a Bergey XL1 on a 12 
> volt battery then the 24MS stator, Classic 150 and a Clipper make a 
> much nicer solution as the Classic 150 can charge up to 96 amps into 
> the 12v battery compared to the Classic 250 being limited to 61 amps 
> so you get a third more power for very little extra and the turbine 
> will not free wheel when the battery is full or the current limit is met.
