304 / Stainless Steel PV Earthing Clip

1. Product Overview

An essential safety component designed to establish reliable electrical grounding across solar PV arrays. Manufactured from SUS304 stainless steel, the earthing clip features sharp teeth or points that pierce through the anodized aluminum film of module frames and mounting rails, creating a secure, continuous, and corrosion-resistant grounding path.

3. Frequently Asked Questions (FAQ)

Q1: Why is an earthing clip required?

Anodized aluminum is an electrical insulator. The clip's sharp teeth pierce the anodized coating on rails and panel frames to establish a secure, continuous grounding path.

Q2: How is it installed?

Place the clip between the module frame and the aluminum rail (under the mid clamp). Tightening the clamp forces the teeth to penetrate both surface coatings.

Q3: How many clips are needed per solar panel?

Typically 1 clip per mid clamp (or 2 per module, depending on engineering requirements) to bond adjacent modules along the rail.

Q4: Will 304 stainless steel cause galvanic corrosion with aluminum?

No. SUS304 stainless steel is galvanically compatible with AL6005-T5 aluminum under mechanical pressure, ensuring a 25-year lifespan outdoors.

Q5: Does every panel still need an individual ground wire?

No. Earthing clips bond panels together along the rail. You only need one grounding lug per rail row to connect the array to the main earth ground.
