I've got one as well which has been in for 2 months. Been working fine but did start to give blade overspeed error messages occassionally whilst freewheeling which i had to manually reset - until Nick sorted out (fingers crossed). Like all things with computers attached I'm sure they'll have issues (my old Landrover was much more reliable than the new one with a computer attached - took Landrover ages to find the fault !) . I'm very happy with the performance so far and others I've spoken to seem happy with theirs - that's why I went for a Gaia. Hope you get to the bottom of it but don't think the birds nesting can be a manufacturing fault.
There's a farming forum (forget what it's called) which had a discussion about Gaias, mostly seemed positive but one chap did have programming issues. Computers I hate them.
On a positive note the Gaias lightening protection works, we had a strike that fried my home computer, phones, etc but the Gaia restarted itself after the voltage spike had passed.

So what was the simple solution?

My "rotor over speed" error kept on occurring, only in very light winds and was not due to blades actually over speeding. Not really effected generation just meant I had to reset it all the time so my patience finally ran out. Still don't know whats caused it and don't know if it's been fixed - only time will tell. Gaia just seemed to guess at possible causes and gave a list of tweeks to be done - they have been and we shall see.
I'm keeping my fingers crossed.

Bobdbuilder,
Hummm, Sounds like I've got a similar "wiring" issue in the white box - my "rotor overspeed" error still isn't fixed despite the best efforts of Nick. Not really affecting production as long as I reset it each time but it's been doing it for the 7 months its been up.

Gaia say they are taking it seriously and have wired in a modem thing to send data back to the factory but they still don't know why it happens. They keep coming up with things to try but clearly don't know what /why it's doing it and have started to suggest things already tried. Gaia seem reluctant to replace the white box and are keen to find the fault in the field for future reference. Fair enough but you can't rewire the computer standing in the middle of a wet field. I shall be having serious words if they don't have a solution before the end of the month (solution that is and not a guess).

Oh and it's done 16,120kWh in the 7 months. December= 4207kWh .
