Equipotential bonding & earthing

For full K2 Systems recommendation Equipotential Bonding and Lightning Protection for PV mounting systems please visit K2 Systems website.

What is equipotential bonding and earthing?

Equipotential bonding is achieved by conductively interconnected conductive points thus the electrical voltage between the points can no longer be measured.

The connection of a point on the electrical system to the ground is called earthing. This can fulfil certain tasks, such as:

        • Protection against the direct and indirect effect of an electric shock (personal protection).
        • Lightning protection
        • Ensuring electromagnetic compatibility 
        • Protective or functional earthing of certain equipment, such as power inverters

Equipotential bonding and an earthing system complement each other to form an effective protection system.

Equipotential bonding must always be added to PV systems in accordance with the specific national standard. This applies to all conductive and exposed components.

TerraGrif earthing system

        • Simple and fast module earthing solution for all K2 mounting systems 
        • Complies with the earthing provisions in the standards NF C 15-100 and the guide UTE C15-712-1 
        • Tested and approved by LCIE Bureau Veritas 

Attention: For technical reasons, a TerraGrif cannot be used again after it has been used once and removed again. Please also check the TerraGrif assembly instructions.
