Grounding Washer Ω II Type (KBH-PV-20-02)

Grounding Washer / Contact Plate

Stainless Steel A2 (1.4301) | For Photovoltaic Systems

Safe installation – effective potential equalization.
The grounding washer is an essential safety component in PV systems – it ensures electrical continuity between frames, structures, and PV modules. It helps protect against overvoltages and lightning strikes.

How does it work?
Sharp tabs pierce the anodized layer of aluminium, which acts as an insulator
Enables conductive connection with the frame material
Ensures continuity for potential equalization
Installed between the panel and aluminium rail

Material: Stainless Steel A2 (1.4301)
Type 304 – austenitic (non-magnetic) stainless steel
High corrosion and oxidation resistance – due to increased chromium content
Flexible and durable – resistant to stress and weather conditions
Long service life – no risk of connection degradation

Application in PV systems:
Equalization of potential in supporting structures
Grounding connection between panels and aluminium rails
Part of the lightning and surge protection system

Ensure the safety of your PV system – choose reliable grounding with an A2 contact plate.
Small part, big impact.
