2nd Interim report now available.
- As many of you know, I am into an eight-month study on how often BWC's
10 kW turbine, the Excel-s, overloads the inverter it is matched (or
mis-matched) to, the GridTek10. The second interim report (the half-way
report) can now be downloaded from SWIEP R#47 from
The Bergey turbine is now up to 32% energy-loss.
I am guessing this figure will rise a little over the next two windy
months if we get normal weather in Ellenburg, NY. Then the % energy-loss
ought to fall a bit in months 7 & 8 of the study. Stay tuned if you want
to see if my guess is correct. As a reference point, Mike Bergey
predicted only 1 or 2 % energy-loss. It is looking more like his
prediction will turn out to be on the low side of reality.
