LONGi.

Identity and scope

Purchase policies below are a dated source review, separate from individual product specifications and price observations.

Manufacturer/brand, seller and installation provider are separate roles. A merchant profile does not certify that every product is made by that merchant. Affiliate approval and endorsement are not established by these links.

Manufacturer identity/support is separate from seller shipping, returns, freight charges and purchase terms.

No uniform warranty duration is assigned. Exact model, sales channel, installation date/region, purchaser eligibility and applicable document revision must be checked.

US contact page supplies us-info@longi.com. Individual warranty document applicability and claim conditions remain model-specific.

Download page is interactive; bounded capture establishes the official route, not a completed warranty lookup for every catalog model.

Identity

Official LONGi US site supplies manufacturer product/service/download links. Exact catalog label LONGi is reviewed; no third-party similarly named website or later product-brand label is added as an alias.

Warranty handling and support

Official US download center has specifications, warranty, installation and certificate categories. Model generations and document revisions differ; exact applicable US model warranty must be selected. No single product/power duration or US coverage for all imported models is inferred.
