Round grounding washer

Grounding washer – variant III, round, solid, Ø35 mm, stainless steel A2 (1.4301)

The grounding washer is a mounting component used in photovoltaic systems. Its purpose is to equalize potential between frames, support structures, and PV modules, ensuring continuity of galvanic connections throughout the installation.

The washer's sharp teeth pierce the thin anodized aluminum layer that covers the module frames. Since this layer is non-conductive, the teeth enable direct contact with the conductive aluminum underneath, ensuring a secure and durable electrical connection.

Made of stainless steel A2 (1.4301), the washer is corrosion-resistant and suitable for long-term use in various weather conditions.
