Grounding is an important part of solar installations and I am sorry to say it is also greatly overlooked and miss calculated. Properly grounded systems are even more important today where Grid-tie systems can be up to 600VDC. So please take the extra steps to make your solar system safe for you and your family. I don't want to be an alarmist but from all the photos I have seen, fires caused by poorly grounded systems are not pretty. So do it right. |

WEEB stands for “washer, electrical equipment bonding”
The WEEB family of products are used to bond solar modules to
aluminum solar mounting rails. The mounts are then grounded so the entire
assembly is grounded. This eliminates the need to use a
lay-in lug and thread-forming screw on each module and it eliminates the
need to run a continuous wire to each module.
This saves time and money and it meets the requirements of UL 467.
Wire is only needed to connect a lay-in lug on each module rail to an
equipment grounding terminal in the inverter or disconnect. ETL listed to UL
standards
The WEEB-9.5 is used for bonding modules to mounting structures when the modules are directly bolted to the rails using 1/4" bolts through the mounting holes on the rear of the module frames.
This type of mounting is typical on DP&W ground and pole mount systems (pages 42-48) and on Wattsun and Zomeworks trackers (49-51). The WEEB-9.5NL is used for bonding strong-back structure and legs to the rail where 3/8" bolts are used.
Sold in packs of 100.

grounding
clips are used between modules and UniRac SolarMount Standard Rails or
SolarMount Light Rails when front mount clips are used to hold the module to
the rails.One clip grounds the frame of 2 adjoining modules to one of the mounting rails. Two clips are required for each pair of modules so that the modules will be bonded to both rails.
Sold in packs of 100.

WEEB-PMC grounding clips
are used between modules and ProSolar rails when front mount clips are used
to hold the module to the rails.
One clip grounds the frame of 2 adjoining modules to one of the mounting rails.
Two clips are required for each pair of modules so that the modules will be bonded to both rails.

The
WEEB L-6.7
provides a connection to the mounting system and has lay-in provision
for an equipment ground conductor. The WEEB-6.7 kit includes the lay-in lug,
matching WEEB washer, bolt, nut flat washer and lock washer.
Two WEEB lugs and a short piece of bare wire can be used to connect across a rail splice, or a WEEB splice kit can be used.

These tin plated copper lugs have stainless steel set screws and come with stainless steel thread-forming screws and lock washers, to meet NEC requirements for connecting a continuous ground wire to all modules in an array and having the ability to remove a module without breaking grounding continuity for the rest of the aray.
Sold in packages of 10 with
thread-forming screws.
UL listed.
