Lightning Protection for Nigeria projects, made in India

IEC 62305 is the current international standard for lightning protection, covering risk assessment, protection levels and the full LPS design methodology, and is what most export/international projects reference. IS 2309 is the older Indian code, still referenced on some domestic projects. IEC 62561 separately covers the component-level test requirements (clamps, conductors, terminals) for both. Ask which your project specifies; they are not interchangeable frameworks.

Commercial invoice and packing list, material certification for conductor tape (copper purity or GI galvanizing thickness), IEC 62561 component test reports where specified, and a Certificate of Origin for duty relief. For projects requiring a formal LPS design, a risk assessment and protection-level justification per IEC 62305 may also be required from your design consultant.

There's no fixed minimum. LPS components, air terminals, conductor tape, clamps, typically get ordered against a specific building or structure's design bill of quantities, and often travel consolidated with earthing material into one shipment.

A perimeter LPS earth conductor with multiple driven rods (typically every 30–50 m) is bonded to the array's earth grid. Modules and inverter cabinets are bonded to that grid. The whole forms a Type-B foundation earth that meets IEC 62305 and IEC 61730 (PV-specific). We design the configuration on request.
