SunModo Self-Bonding System
SunModo developed a proprietary grounding and bonding system that is built into the mounting
hardware for the rails, clamps and splices. We provide further grounding through all of the SunBeam
racking components including the Pipe Caps, Beams, Posts and Post Base Plates. All hardware meet
UL 2703 Grounding and Fire Standards tested by ETL.
The basis of the system is our patented stainless steel floating grounding pin which is designed to be
captive in the mounting components and provides a bonding path from the PV panel frames to the rails
and rail splices, and finally to the ground lug. The self-grounding and bonding system is for use with
PV modules that have a maximum series fuse rating of 30A. The maximum number of PV modules is
limited by the system voltage, so in a system has multiple inverters, the SunModo racking system can
theoretically go on forever.
Finally we have added a spring and Blue 242 Loctite to our Mid Clamp assemblies. The sprig keeps
the Mid Clamp in the open position ready to receive the solar module. The Blue Loctite is a light
bonding agent allowing the T-Bolt engagement into the Rail when the Collar Nut is turned from above.
The Blue Loctite has the added benefit of being an anti-seize agent for stainless steel hardware in the
area where it is applied. For additional anti-
seize protection refer to the ‘Tools Required for
Ins
tallation’ section of this document.

Similarly, the rail splices the grounding pins, eliminating the need for extra bonding components.
