I, too, have had some experience with Exeltech. I think it's an excellent
product and the installs I've done have been trouble free. It's a little on the
pricey side but an excellent system. I liked the fact that everything is rack
mounted.

Hi Bob,
3M VHB 4945 is the good stuff. You will need to properly prepare both
surfaces for best adhesion. Do not assume that just wiping the surface with
a rag will suffice. Particularly painted &/or oxidized surfaces. Use a
cleaning agent and clean rags or cloths. Works best with moderate
temper
We have been using WEEB clips on all of our installations for over a year
now. We include the WEEB data/installation sheets in our permit package and
patiently point out the clips to inspectors who haven't seen the WEEB system
yet.
Two questions:

I've never used the ProSolar rails, so I can't speak to 1).
On 2), yes, you must bond the rails with a listed device if they are not
bonded to the modules. The nice thing about the WEEB is that it allows one
to bond the modules and rails together, and then you can pick up the bond

(1) it appears that per the WEEB installation manual:
http://www.we-llc.com/Datasheets/104-0404-08-008.pdf
(page 8) you need to have one WEEB per module rather than one for every
other module as you suggest.
(2) 690.43 Equipment Grounding.

On page 8 it would appear that we need TWO WEEB clips bonding modules A and
B to rails #1 and #2 and another TWO WEEB clips bonding modules C and D to
rails #1 and #2, etc. - Peter

We have been using Buchanan brand "splice caps" to splice two to three #10
Cu EGCs inside 3R-rated j-boxes. Is there an approved methodology for
splicing ECGs under PV modules (i.e. exposed to the elements). I understand
that otherwise listed lay-in lugs are not acceptable for double lugging. -

What economical splice hardware are people using when you don't have two end of
a ground wires to land in the Buchanan Splice Caps? Split bolts are mighty
expensive

Yes, that's correct. In my answer I was just rephrasing it to say you'd
need twice as many WEEBs as you think. As I understand it, the intent of
this layout is to give the installer two chances to bond each module
properly to the rail.
Unirac has a similar requirement for its UGC-1s on SolarMo
That still works to approximately one clip per rail (actually N-1 clips for
N modules). - Peter

Hey all,
I have a client who was off grid and is now grid tied and has [2] Trace SW
4024 Inverters. I realize the parameters are not the best for high
efficiency but the client is not into changing out to newer equipment.

We use these Panduit C-taps:

They work great and the compression tool is relatively inexpensive but there is
question about whether they're listed for use with solid wire.

Hey GuysUnirac recently changed their requirement to 2 clips between
each module...one on the upper rail and one on the lower
rail..therefore by my count you need 2N-2 clips for N modules, you don't
need any clips at the ends of the row of modules the link to their
diagram and
Hi Dana - I will get Nick Klein from our tech support team to contact you
about this to see if there is anything you can do. Generally an additional
GTI unit is required to enable the grid-tie capability of the SW series,
and I think they are pretty hard to find these days.
Cheers,
Mark

August,
If these are equivalent to the T&B part, they are rated for solid
or stranded wire. Take a look at page B43 of

Wrenches,
Our customer has 24 each Kyocera KC130 modules and wants to go grid-tied.
Can he use an SMA SWR2500U inverter with the fan kit? Is there a better
inverter that will use all of his modules? If you have an SWR2500U or a
better inverter option for sale, please contact me off-list. Thank
Kent,
Yea, it seems that the T&B parts are rated for #10 through #6 solid wire but
not if you're splicing #4 or greater. I can't say for sure that the Panduit
part is the same but I know from experience that the bond is excellent. They
truly are basically "irreversible" in that you need to cut

set ABSORPTION TIME to 0:00 on both machines.

For your SW4024 to connect to a GTI, it needs to be "GTI-ready." A
GTI-ready inverter has a second modular connector on the circuit board near
the AC connections. This is for the data link to the GTI. Way back when,
Xantrex was taking back SW inverters to modify and redeploy. I d
Joel,
The SMA SWR2500U inverter has been a long discontinued model. If you want to
use an SMA inverter, go to the SMA website to use their excellent sizing
program. Plug in the module, and your record minimum and average maximum temps
for the site, and look for a current model inverter that wil
