Grounding washer for photovoltaic installations

This component is key to the safe and reliable operation of your PV installation. The grounding washer serves to equalize the potentials between the frames of photovoltaic modules, the supporting structure, and the modules themselves. It ensures galvanic continuity of connections, which is particularly important for protection against overvoltages and ensuring user safety.

Solid construction and materials

Made of high-quality A2 (1.4301) stainless steel, the washer is characterized by exceptional corrosion resistance. This guarantees long-term and trouble-free operation, even in harsh weather conditions. A2 steel is widely used in outdoor installations due to its anti-corrosion properties. The washer dimensions – 40 x 40 x 10 mm – ensure a stable and secure connection.

Installation and application

The washer has sharp protrusions that allow piercing the thin layer of anodized aluminum on the frames of photovoltaic modules. This provides direct contact with the conductive aluminum, ensuring a durable and effective electrical connection. Installation is simple and quick, and the washer is compatible with various types of profiles and panel frames – both silver, anodized, and painted. It is recommended to use at least one washer between panels for optimal safety.

Benefits for the installer and user:

• Safety: Provides effective grounding of the PV installation, protecting against overvoltages and electric shock.
• Durability: Made of A2 stainless steel guarantees corrosion resistance and long-term operation in harsh outdoor conditions.
• Easy installation: Protrusions facilitate piercing the anodized aluminum layer, ensuring a quick and secure connection.
• Versatility: Compatible with various types of profiles and photovoltaic panel frames.
• Galvanic continuity: Ensures proper operation of the electrical protection system.
• Compliance with standards: Enables meeting safety requirements in professional PV installations.
