In case you don't understand, it means in 20 years there is a 96.5%
chance there will be no problem with a modern inverter. *As mine is
installed in an ideal situation (ie cool, dry and dust free) I expect
it will be even more reliable than that.

So if you have 100 of them (I assume there's one in each turbine?) that
gives you about a 2.8% chance that there won't be a failure, or 97.2%
chance that there will.

100 turbines, that's what, about 5 wind farms or so?

Although on the bright side, since each one contributes the cube root of
FA most of the time, you might not notice ;-)


I expect you've got a link to verify this remark?
