When in doubt .. ask the manufacturer.

Benn...it looks like that lug has "stainless hardware for corrosion
resistance" as stated on the brochure....That would be the biggest
consideration as David Brearly mentioned earlier in regards to rust potential.
Stainless hardware and tin plating is equivalent to the WEEB lugs....Tin
plating and stainless hardware is as good as anything else available as far as
outdoor ratings are concerned.....
I see your point that it is not explicitly stated for outdoor use....however
being marketed for use with solar panels also seems to imply rather obviously
that it is outdoor rated.....in my unofficial opinion.

Thanks for the feedback Wrenches, lots of interesting comments,
However I'm still wondering…..How does one confirm that it is specifically
approved for outdoor use? Other than assuming it is implied (because it is
'marketed' as a solar lug). As far as I can tell UL 467 does not imply
"outdoor rated" as the aluminum lug "GBL-4" is also UL467 listed. See here…GBL
LAY-IN AL/CU.
As well, and as Gary pointed out with his second link, for a module
bonding/grounding method to be acceptable, it must be recognized by the module
manufacturer, no?Which means that any new bonding product on the market must
have the blessing of each mod mfgr.
(by way of letter or mention in its install manual). I have come across
inspectors that actually look for this.
Jason, you wrote "I like the looks of that lug. However, I've been using WEEBs
too long to go back now." I agree, and i'm not looking to replace weebs with
these, but these certainly seem to have a place in the What do you use for the
bonding connection from the ?rails?
This SGB lug was suggested for this purpose as well.

Here's the Ilsco

The GuideInfo for Grounding & Bonding Equipment lists:
Grounding and Bonding for
Photovoltaic (PV) Systems — Grounding and bonding
equipment intended for use in PV systems are additionally
investigated in combination with the PV module/panel (see
QIGU) to the applicable requirements for such products.
Installation instructions provided with the PV system (see
QIGU) identify the specific grounding and bonding device that
has been investigated and intended for use with that system.

Yes, sorry. I wasn't speaking of this lug...I like the
redesign. Looks quicker and easier and robust.

Yeah, but this one is marketed as a

appropriately rated for outdoor use. It's always good to
double-check, of course.

Some of the aluminum
lugs are indoor-rated. They have a set screw will
rust in an outdoor environment. That's one of the
classic John Wiles slides. I'd just watch out for
that....
