AI-Powered supplier vetting

SummaryCiFiSUN Energy Co., LTD is a China-based limited trading company established in 2016, offering PV modules, LiFePO4 batteries, and inverters. The supplier reports OEM service for well-known brands, customization across several levels, written quality and service procedures, inventory capability, and battery output of 1,000,000 pieces. Its stated export sales share is 71%–90%, with North America among its export markets. However, the evidence is inconsistent regarding organizational scale and production status: it is identified as a trading company with nine employees and a 90.0 m² plant, while other information reports substantial battery output and 50 quality-control staff. No SDK is available, and there is no overseas warehouse or showroom. Certification ownership, named customer cases, and verified after-sales outcomes are not sufficiently documented.

Supplier typeThe supplier is identified as a limited company and trading company headquartered in Nanchang, Jiangxi, China, established in 2016. Its stated product scope includes PV modules, LiFePO4 batteries, and inverters, while its business scope also includes charging-related equipment rental and EV charging infrastructure operations.

After-Sales capabilityThe supplier reports customer-service personnel, written service-assessment procedures with records, clear complaint-handling procedures, and a corrective/preventive-action mechanism. It also reports inventory capability, but lacks overseas warehouse and showroom services; the evidence does not establish response times, service coverage, or actual after-sales performance.

Production capacityReported production information includes 1,000,000 LiFePO4 battery pieces annually, inventory capability, standardized production procedures, and a stated intelligent factory workshop. However, the supplier is also classified as a trading company with nine employees and a 90.0 m² manufacturing plant, while outsourcing procedures and contracts are marked unknown, creating unresolved uncertainty about direct manufacturing capacity and control.

Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, full customization, minor customization, and flexible customization. Its stated focus on bespoke solutions for a wide range of applications supports a broad customization offering.
