Doug, I never did get a diagnosis of the problem from Bergey or the installer. You know in modern electronics with complex 'motherboards' it is cheaper to just...
Hearing what you are saying seems to explain the noise. My educated guess is that the IGBTs fire out a pattern of pulses, varying in voltage to make a stepped...
And what is "Cp"? ... From: Mike Hess To: SWIEP@yahoogroups.com Sent: Wednesday, April 09, 2008 7:04 PM Subject: RE: [SWIEP] Re: [a-w-h] A few comments about...
Mike, Thanks for telling me that. Can you give me a reference (book or journal paper) that explains how one can maximize Cp? I had assumed Cp was determined...
Steven, I have looked in moderate detail at the specs for the WindyBoy. It expects DC volts in to be within an expected V and power (kW) range. So you would...
I'm certainly no electrical engineer, but I don't see why a given inverter has to be "adjusted" to work with a specific turbine. What are they tweaking for? ...
Nando, By all means, please contact Mike Bergey. He is tired of hearing from me, and I have never had a satisfactory exchange of technical information with...
Steven, I have been looking into alternatives. Most inverters have to be sized and designed to work with a specific turbine. I know of two other inverters that...
Nando, Thanks so much. I want to investigate options. This is difficult to do without knowing a lot of technical information about how the GridTek10 works. Do...
NEWS: Update, my comments about Mike Bergey's new blades finally got posted on the AWEA Yahoo! Group. Censorship (if there was any) can be overcome! More...
Update to 18 SWIEP members, First let me thank the 18 people who joined SWIEP. Thanks for taking the time to find me. So far the only way you know about me is...
REGARDING performance of new and improved wind turbine blades. Here is a copy of my response in the AWEA Yahoo! Group: I respectfully disagree with Mike...
Hi, I have just attached some file and links to my University of Alberta sponsored SWIEP URL. See Links in the SWIEP Yahoo! Group. My website is not working...
Hi Doug, My brother is an electrical engineer and he also suggested grounding the GridTek10 inverter. I pounded an 8 ft (2.4 m) copper rod into the ground ...
1: Thanks for this forum. I look forward to reading, learning, and sharing here. 2: Your AM noise problem... I know a little about "noise" from a industrial...
Steve, The Geothermal figures I sent you are actual measured values so they are correct. I have power monitors all over the place. But we are probably getting...
Thank you Mel! I'll definitely take a close look at them. If they're as solid as Bergey I may give them consideration. At least it's another option, might...
Thoughts interleaved. ... From: meltyree1 To: SWIEP@yahoogroups.com Sent: Sunday, March 30, 2008 7:44 AM Subject: [SWIEP] Off grid and Geothermal (To Steven) ...
Hi, Lots of people have been asking me for links to download power curves from the U.S. Department of Energy, National Renewable Energy Labs (DOE NREL). As an...
Steven, Okay, here is my second message. Although I heat my house with a `5 ton' (= 60,000 BTU) Geothermal Heat Pump powered with energy from the sun and wind,...
Hi Steven, Our message stream is getting too big so I started a new one to answer your main points in two messages (see my other). Good news: you can get a...
Thoughts inline. ... From: meltyree1 To: SWIEP@yahoogroups.com Sent: Saturday, March 29, 2008 4:26 PM Subject: [SWIEP] Re: Off Grid CO home Steven, I have a...
Steven, I have a net-zero energy house (and zero-emission house). Give me a couple of days and I will get info about the house design on my SWIEP web site...
Actually my aim is a 10kW Bergey (roughly 7.0 kW at that altitude) with, maybe, a 2-3 kW solar supplement. The contractor I eventually pick is going to have to...
Steven, So I take it you are in CO. That is great country for PV and passive solar home heating plus you say you have wind resource! So with some thought, you...
Howdy all! Don't own one yet but am getting ready to buy/install one soon. I'm building a custom home that is off-grid (not really by choice, but just the way...
We have 5 new members today. GREAT! The site is only 3-days old. Do any of you own small wind turbines? Do you know anyone who does? If you know about owners...
Hi, I have just launched SWIEP. If you own a small wind turbine, we would like to here about your experiences. If you are thinking of buying one then check in...
