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, Readers of SWIEP will know about my continued interest in the conditions under which energy is lost by the GridTek10 inverter when connected to a...
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...
Further East, as in Greece? Slovenia? Bosnia-Herzegovenia? Serbia? No - wait, Hungary? Bulgaria? I've got it, the Ukraine! Still not right? Russia? Gee whiz;...

Hi all, I wish to set the record straight about SWIEP which I started as a 'consumer reports group' and outlet for research results. A personal message from...
Logan, Thanks so much for your detailed and very astute comments. Please see my comments below. CAN I BE A BETA TEST SITE FOR THE NEW INVERTER!!! See below. ...
Hi Nando, You have a schematic for the GridTek10 I sent you, which is not complete but helpful. Put yourself in Mike Bergey's shoes and tell me what you would...
Mel: Short message, as it is designed, all the parts are at the maximum allowed operating voltage capabilities. The generator produces around 430 volts where...

Nando, I guess you are telling me this is not an easy conversion and this agrees with what others have told me. So putting myself in Mike Bergeys shoes, and if...
MEL The Bergey 10 KW may be a good wind mill. The basic problem as stated by me before is the wind mill/generator coupling which I believe, strongly, that...

Nando, Is the 1/4 setting you are talking about in reference to 1/4 furl I talked about earlier? If so I think what they mean is you manually furl the tail so...
Doug, I was inspired to document this topic (performance of the GridTek10) because Mike Bergey emphatically told me it could not be improved and that the known...
Mike, Thanks so much for your detailed comments; I know you are a busy man so thanks for the effort. Your input is very important and appreciated! Will your...
Mike Bergey: I read with great interest your message and I read it several times to make sure that I understood all what you say. 1) It has been logical that...

Hi Steve, No, you are not missing anything here. The system you propose to install at your new home is battery based. It uses a different version of Bergey...
