Rooftop/Combiner splicing is a perfect application for the use of splice capped
crimp sleeves. The other is where splices are subject to vibration. Their usage
seems to vary throughout the country. In NW Oregon, where I came up in the
trade, it was protocol to use them in places like rooftop

Never had an issue, they crimp fine. But just like with any electrical
work, you must pay attention all day long!

Wrenches,
I would like to concur with Mike from MDElectricSolar. My rooftop
junctions always use Buchanan copper sleeves crimped with the Buchanan
C-24 crimp pliers. After twisting the stripped ends together to a length
exceeding the sleeve length I apply No-Ox-ID A Special grease to the
We’re using ideal/Buchanan splice cap crimp connectors as I’ve posted here
a couple of times:

We really like these in nearly every way. I just spoke with Ideal
Again, I am using Buchannon copper crimp sleeves, with a Buchannon crimper,
never seen one NOT work or go BAD. This is the best connection I have seen.
I've never had an inspector open up my rooftop j-box/combiner box and ask
about the listing of my connectors, but as a solar business owner who's
The reason i'm asking is that the only time i have seen a short,
first-hand, in a wire nut, was because it appeared that one wire was pushed
down rather than binding with the other wire, which would have happened if
the wires were not held tightly when the nut was twisted on. Also, it was

All the other nuts are tight so l cant not say it was or not but l see this

Jerry,
Can you confirm that this was caused by a failure of the wire nut, itself, and
not due to user error (not properly stripping enough jacket, inserting even
length wires and sufficiently twisting on the wire nut)

Hi Larry
John Pfeifer at Apollo Solar sponsored the testing and now John has disappeared
from the solar scene altogether. I don’t have any contact info for him. BTW the
Concordes have been working without a hitch for eight years now.
Kind regards

It looks like the UPG batteries come from the same Chinese factory as well.
We’re hoping the Trojan Reliant work out well with their re-introduction Q1
2017.
AGM batteries seem to be the most misunderstood (after Gels) I have noticed the
failure rate is higher than wet, I assume most
