Has anyone diagnosed truly failed diodes? Or pinpointed other failures in the
junction box or cell groups that could open circuit them?
I’d really like to see some thermal images!

Hi Adam,
I have a 3.3MW site using Hanwha 400s where IV curve tracing and other
voltage checks found roughly 1% of the modules are experiencing some type
of voltage issues. We all suspect bad diodes. We just got the site up and
running and we will be doing an aerial thermal imaging flyover to de
. Where would 300A of current ever flow?
What is someone dropped a wrench on the bus? It would fault with greater
than 200 amps. This is and has been the point behind this code section.

Right. If the sum of the PV source OCPD and all load OCPD in the main panel
is less than or equal to the busbar rating, it complies
with 705.12(D)(2)(3)(c). Label the panel as required and you're all good.
Loads beyond the interconnection point do not matter for purposes of
705.12(D)(2)(3)(c) as lo
On that note, is there a device made to physically prevent additional breakers
from being installed in the meter main? And also the two SP meter main breakers
would have a combined ampacity limit.
