AI-Powered supplier vetting
SummaryGuangzhou Congsin Electronic Technology Co., Ltd is a China-based limited company established in 2021 with 54 employees and a 925 m² manufacturing site in Guangdong. It operates four production lines, has 11–20 quality-control staff, and produces power inverters, solar charge controllers, and related products. The supplier states that it exports to more than 40 countries and that exports represent 90% of total sales. It reports OEM/ODM capability, two years of R&D engineer experience, automatic wave soldering and multifunction testing equipment, and a one-year warranty for power inverters. However, no supplier-management-system certifications are listed. The provided information supports production, export, customization, and after-sales claims, while financial credibility and customer-case strength remain insufficiently evidenced. Reported output figures contain inconsistent entries, so production scale should be verified before reliance.
Supplier typeThe supplier is identified as Guangzhou Congsin Electronic Technology Co., Ltd., a China-based limited company established in 2021. It reports a 925 m² manufacturing plant, four production lines, and business activities spanning manufacturing, electrical and electronic products, and consumer electronics, supporting classification as a manufacturer rather than only a trading intermediary.
CertificationsThe supplier-management-system certification field is explicitly recorded as NIL. No certification evidence is provided in the available information, indicating a documented gap for this field.
After-Sales capabilityThe supplier explicitly describes itself as a reliable power-inverter supplier offering a one-year warranty. This is direct evidence of a defined warranty-based after-sales commitment, although no further service-process or response-time details are provided.
R&D capabilityThe supplier reports an R&D department, professional engineer support, OEM/ODM project capability, automatic wave soldering machines, and multifunction testing machines. However, only two years of total R&D engineer experience is stated, and no patents, proprietary technologies, or product-development results are provided.
Production capacityThe supplier reports four production lines, 11–20 quality-control staff, product-specific output information, and fulfillment within 15 working days in both off-peak and peak seasons. The output data contains inconsistent and unusually large entries, so production capacity is supported in principle but requires verification.
Customization capabilityThe supplier explicitly states that its R&D department supports OEM and ODM projects and that it has professional engineer support. Its stated export experience across more than 40 countries further indicates experience serving varied markets, although specific customization examples are not provided.
