Earthing electrode variant II PV-20-02

Safety and durability in photovoltaic installations

Earthing washer is a key element ensuring the safety and reliability of photovoltaic systems. It is used to equalize the potential between the panel frames, the supporting structure and the PV modules, minimizing the risk of overvoltage and damage caused by lightning strikes. Its use is particularly important in professional installations where high corrosion resistance and long-term operation in atmospheric conditions are required.

Construction and operation

Made of high-quality A2 (1.4301) stainless steel, the washer is characterized by exceptional durability and corrosion resistance. Sharp protrusions on its surface effectively pierce the anodized aluminum layer that covers the frames of photovoltaic panels. This layer, although protecting against corrosion, acts as an insulator - the protrusions of the washer provide a conductive galvanic connection, essential for the proper operation of the grounding system. This allows for safe discharge of excess energy in the event of overvoltage.

Installation and compatibility

The washer is extremely easy and intuitive to install - it is placed between the photovoltaic panel and the structural profile. It is universal and compatible with most mounting systems available on the market. Its small size does not affect the aesthetics of the installation, and at the same time guarantees effective protection against the effects of lightning strikes. By choosing this washer, you are investing in the long-term safety and reliability of your PV installation.
