Ok cleared my head this am.

Again we have about a 5mph wind - you know it really is true that once you get a wind turbine spinning that you will not have wind! And it is the same forecast for the next week!

Using my meter I checked the voltage from ground to each leg of the 3-phase output from the turbine and each was 24v, which should give me about 33v after the rectifier, so I do not appear to be at cutin speed.

I went back through all my settings on the Xantrex and everything appears to be set correctly.

I think that I may just have to let it wait for more wind...

That's one of the biggest limitations of wind turbines, they need wind.

You will certainly not be cut in at 24v ac. Usually below cut in the volts drift about, but become steady once your peak equals the battery volts.

Probably just as well you get nothing in a 5mph wind, if you make the cut in low enough to do so you will kill the performance above 10mph. Just be patient wind often goes away for several weeks but the damage is not permanent.
