Solar Grounding Bonding Jumper

The solar grounding bonding jumper is designed to provide a reliable electrical bonding connection between conductive components in photovoltaic (PV) mounting systems. It ensures continuous grounding across solar modules, mounting rails, and aluminum structures, enhancing system safety and electrical performance.

Constructed from tin-plated braided copper with stainless steel connectors, the bonding jumper offers excellent flexibility to accommodate thermal expansion and contraction caused by temperature changes. This design minimizes mechanical stress while maintaining a stable, low-resistance grounding path throughout the system’s service life.

By bonding multiple PV modules to the mounting structure, the jumper reduces the need for individual grounding wires, simplifying installation and improving overall system cleanliness. It is compatible with standard aluminum rails and metal roof solar mounting systems, including standing seam and rail-based installations.

Applications

• PV module grounding
• Solar mounting rails and aluminum brackets
• Grounding continuity for metal roof solar systems

Material

• Tin-plated copper braid
• SUS304 stainless steel hardware

Specifications

Installation Guide

1. Insert the bonding jumper into the top mounting slot of the rail.
2. Secure the jumper by tightening the flange nut to 8 ft-lbs torque.
3. Position the grounding washer with nibs and the grounding T-bolt on the rail.
4. Apply pressure to allow the nibs on the washer and T-bolt to penetrate the rail’s anodized surface.
5. This creates a direct grounding path from the solar panel through the bonding jumper, ensuring effective electrical grounding.

Key Features
