Hi all, The Xantrex-built grid-tied GridTek10 inverter sold with the 10 kW Bergey turbine is poorly designed. Under windy conditions, it is prone to bus...
Pretty neat Mel....thank you! Seems like this would be a natural for them to just add this, don't it? Steve ... From: Tyree, Mel To: SWIEP@yahoogroups.com ;...

Hi All, I just wanted to share some production numbers from my wind turbine here in Spencer, IA. Just as a reminder, I have a Bergey 10 KW on a 120 ft guyed...
Hi Paul, Unfortunately the file you attached is not an Excel file. Neither is it a csv file. Please try again. I am very interested in seeing your data! Do you...
Hi all, Readers of SWIEP will know I have suspected 10 to 20% energy production losses in 10 kW Bergey turbines GridTied by Xantrex's GridTek10. Mike Bergey...
Doug, I agree with your comments. A sample of ONE is not enough. But you have to do the first study to raise awareness and justify follow-up studies! Mike...
Hmmmm. I wouldn't be too surprised if the "new" inverter turned out to be a Magnetek Aurora - a good unit, but not exactly new. Correct me if I'm wrong, Mike....

Matt, The rumor is that the Magnetek Aurora is the inverter under 'development' for the Bergey Excel. However, I have my own plans to try one if it is not made...
Mel: The 95 to 98 % is the "sweet" spot of the inverter, a broad range efficiency for this type of inverters are below that, I would say, around 86- 92 %. The...

Hi all, Brent Summerville at Appalachian State University has just released a new power curve for the Skystream. The folks at Southwest Wind Power have been...
Having looked at a Bergey XL recently, it appears they have the same 3 phase ac output and rectifier bridge we use in our axial flux units. Why not let the...
Hi Paul, I wonder if you would share with the group more details about how you are collecting these data. You kindly sent me an Excel file but I could not make...
Hi Mel, The data is logged every 30 seconds. If you look in column A and compare one row to the next you will see that the times are 30 seconds apart. Column...
Paul, Thanks for explaining the meaning of the file you sent me. It looks like you a setting on a pile of very useful numbers, i.e., energy production with a...
Doug: You are right in your guess. The inverter runs quite warm when it pumps a lot of energy into the grid. There is a huge heat sink on top with a...
Paul, Thanks, we will look forward to future updates. Your data will be very interesting because you are in a quite windy location in Iowa HENCE (1) Either...
