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.

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:
(1) For ProSolar rails, can we use one
Peter,
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
from
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
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.
Whom at which telephone @ Xantrex might be the best bet to talk to

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.

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

We have three of the Xantrex/Trace GTI units, with one still-in-the-

They're collecting dust on the shelf... I'd be more than happy to
send them to a new home and free up space.

Kent,
Yea, it seems that the TB 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

Here is the method I found to be most effective:
INVERTER SETUP (MENU 9)

BATTERY CHARGING (MENU 10)
set ABSORPTION TIME to 0:00 on both machines.
set MAX CHARGE AMPS to 1 amp on both machines.
