Hi Dave,
If I was your AHJ then sure but since I’m not, you would need to work through
their comfort with this approach since the 690.12 Code language is “PV system
circuits installed on or in buildings shall include a rapid shutdown function
to reduce shock hazard...”
Note the requirement appl

Hi Jay,
Ray makes the right distinction between the PV system and other systems that I
think applies to your example. This was the big change in 2017 as we pulled all
the non-PV stuff out of 690 and created 706, 710, etc. The PV system disconnect
is what you identify it to be though. Article 69
The PV system (and 690.12) stop at the PV Disconnect. (see figure
690.1(b), Note (2)). Charge Controllers are part of the Energy Storage
system (706) now. We presented this in our plan sets, and we drew clear
lines on the wiring diagram showing which articles applied to which
parts of the sys
Matt,
What you are hearing is alternator noise. It's caused by the
vibration from the permanent magnets passing by the alternator
coils.
All turbines produce some alternator sound, some more than others
and the tower itself can act as a resonator, amplifying the
Friends,
I've exhausted the Bergey tech support expertise on this issue and I'm
hoping someone on the list may have a solution to share.
I have a customer with an older XL.1 on a tilt-up tower. The machine has
been in place since 2007. I've done some work to it over the years
including blades, y
