AI-Powered supplier vetting

SummaryYangtze Solar Power Co., Ltd. is identified as a Chinese manufacturer/factory producing lithium and VRLA battery products for solar storage, wind energy storage, telecommunications, UPS, fire alarm, and emergency lighting applications. It holds ISO9001:2015 and CE certifications and accepts multiple quotation and payment terms. The supplier demonstrates broad customization capability, exports 90% of total sales, and reports seven years of export experience. However, service procedures lack records, and it has no overseas warehouses, showrooms, agents, branches, or offline trade-show participation. R&D is supported by an available SDK and customization, but no new product was developed in the past year and no ODM service is offered. Financial information is only represented by reporting years, without sufficient evidence to assess financial strength. No Fortune 500 cooperation is reported.

Supplier typeThe supplier is explicitly classified as a Manufacturer/Factory and operates as a Limited Company in China. This directly indicates manufacturing status, although the provided information does not quantify production scale or capacity.

CertificationsThe supplier reports an ISO9001:2015 management-system certificate and CE product compliance certification. These certifications provide explicit evidence of quality-management and product-compliance credentials.

After-Sales capabilityThe supplier has written procedures for service assessment, corrective actions, and complaint handling, but no records for these procedures. It also has no overseas warehouse, showroom, agent, branch, or offline trade-show experience; therefore, service infrastructure is limited despite stated procedures and lead times within 15 workdays.

Production capacityThe supplier is identified as a manufacturer/factory and lists multiple battery types, including lithium, VRLA AGM, VRLA GEL, tubular plate OPzS, and OPzV products for several applications. The slices do not state production volume, equipment, workforce, or capacity metrics.

Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, full customization, minor customization, and flexible customization. The same broad customization range is reported under both design services and R&D capability.
