I attended one of Mr Wiles seminars years ago and the pics of his system
were truly ugly. That would have been an embarrassment with those of us who
take the time to make things look good as well as be code legal.
I also found him to be arrogant and opinionated.
That's just my opinion of course, bu
There are issues with some combiner boxes, when the fuse holders are
opened under load. The current can (reportedly) make a continuous
arc across the contacts. This is true for the higher voltages, for
grid tie inverters, and would be true for AC coupled off grid
systems. Maybe 100 V would n

I could tell you the reason why the Code panel was disbanded
(reassigned) by NFPA. I was on the panel since 2002 and am on the
current 2011 CMP #4. Panel 13 had jurisdiction over several articles
including PV. Two of the issues (Article 695, Fire Pumps, and Article

Chinese quality will improve for sure and trust is something we ought to get
used to. The Chinese own more US Treasuries than anyone breathing on this
globe, so we are married at the wallet. If our government can have this type of
relationship, it is only going to "grow" as time moves forw
So if we should choose to ignore the humanitarian issues, and just
approach it from a financial sense, how does sourcing Chinese modules
improve our balance of payments?

Good questions. The humanitarian one first. If we use a computer or cell phone,
we are probably contributing to the problem daily as these devices are made
there. The list of items we manu there is growing that we all seem to use in
our daily existence. This is a difficult and perso
Wrenches,
I agree with Bill Brooks on the risks of purchasing from smaller less
established companies. From what I understand these modules are basically
hand made and QC along with material selection can make a major difference
in longevity.
