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 folk
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

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)

All the other nuts are tight so l cant not say it was or not but l see this
alot and this was one that was caught just at the right time.

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
a strand
Be aware that SMA explicitly prohibits the use of wire nuts in their
installation instructions on the DC input circuits.

I also concurr, NEVER use wire nuts on the roof, I've personally installed
them, and come back 3-4 years later, and found them melted. Wire nuts are
simply for insulating a splice, not to be counted on for the mechanical
connection. I make my guys twist solid wire together before installing a
wire
Are those wire nuts listed for wet locations? Most ideal outdoor (damp/wet)
rated wire nuts are blue or grey in my experience.

Yes, wire nuts, and loose connections are a big issue in AC circuits as
well. One of my most frequent troubleshooting calls is tracing out
loose/burnt/arcing connections behind receptacles and switches. Usually
caused by sloppy workmanship, or contractors being in a hurry.

The problem is that wire nuts are not intrinsically sound, a good
connection depends on the skill of the craftsman. They are not legal under
the British electrical code, where I did my training, wires need to be
firmly held under a screw as in a terminal. The US would be better to get
rid of these
I was just called last week to a three phase Enphase system installed by
others with three of eight strings that were exhibiting erratic voltages on
random phases. First I checked the combiner panels and everything checked
out. I went to the roof and discovered that wet rated wire nuts were used

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

nuts are not outdoor rated, and the

Do you have any issues with crimping the fine wires that are typically on a
microinverter cable, to a coarse stranded or solid wire?
Or, do you know if there is an issue with using these crimps with fine stranded
wire?

HI All,
Anybody have any PS1 enclosures lying around they’d like to get rid of?
Please let me know

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

Mike: Without doing a lot of research, I seem to recall what you are stating
about using the Buchanan splices is true if the PV wire, micro-inverter trunk
cable, or DC optimizer fine stranded wire is 19 strands or less.

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 con
