Round grounding washer with a cutout

Grounding washer – Variant IV, round with a notch, Ø44 mm, stainless steel A2 (1.4301)

The grounding washer is a mounting component used in photovoltaic installations. Its main function is to equalize potential between module frames, support structures, and other system components, ensuring continuity of galvanic connections throughout the system.

Equipped with sharp teeth, the washer pierces the thin anodized aluminum layer that covers the module frames. This layer acts as an insulator, so the teeth provide direct contact with the conductive aluminum underneath. This guarantees a durable and reliable electrical connection.

Made of stainless steel A2 (1.4301), the washer is corrosion-resistant and ensures long-lasting, reliable performance even in harsh outdoor conditions.
