Do you have any direct, personal feedback from anyone using a Bergey 850?
A.”We installed the Bergey 850 in March of 1994. According to Karl Bergey, we probably had the first one erected after their test machine. We were the ones who found the furling problem in their original design. The 850 was designed to survive. The Bergey design philosophy was to overbuild this machine rather than depend on controls. That is why it can survive 90 mph winds with no load on it AND without furling. We inadvertently tested this when we installed the machine. A. mistake in the manual instructed us to use fuses that were too small for the 1kw (yes, the 850 will peak out at just over a kilowatt) power output. Then a design flaw (now corrected, of course) prevented the turbine from furling. The winds came to our small hilltop installation and it was not pleasant. Over 90 mph winds, the turbine would not furl and it was freewheeling (no electrical load to slow it). What else could go wrong? Fortunately the floods and earthquakes stayed away. By not furling, it sounded like a he
