Title: Two Classics - one wind turbine
Post by: kitestrings on April 13, 2012, 02:27:49 PM
Hi Ryan,

I plucked this from a recent post, so as not to hyjack Tinman's post on a mostly dfferent subject.  Responding to Mile's situation you recently wrote:

QuoteHere is a link to the power curves we run in My Neighbors 16ft turbine: http://dl.dropbox.com/u/31975941/johns%20curve.pdf

It took me a awhile to get back to this and process the numbers.  If I plot them (as I have it, volts on the x-axis; cummulative current on the y-axis) on a chart it appears that the two units are largerly linear, with a slightly earlier start for the second unit (and little 'wiggle' at the transition).

I was recalling an earlier set of charts with two Classics where the first unit went linearly from say 60-120V, but then went sharply up to ~145V at/near the current limit; then the second went sharply form ~90-120V, and flattened out to the 145V range.  Just wondering if your thinking and/or experience had changed on how best to have two units connected?

Secondly, I'd understood that ther might soon be a firmware upgrade that would allow two units to play well together?
