SummaryGuangdong Xindun Power Technology Co., Ltd. is a China-based limited company founded in 2010, operating from Foshan, Guangdong. The available information identifies it as a comprehensive manufacturer and seller of solar inverters, hybrid inverters, solar systems, UPS products, controllers, batteries, and related power-supply equipment, although another record classifies the company nature as a trading company. It reports a 6,000 m² manufacturing plant, five production lines, 123 employees, 11–20 quality-control staff, and stated annual output for several product categories. The supplier holds ISO9001:2015, ISO14001:2015, and ISO45001:2016 management-system certifications, and reports product approvals including CE, IEC, TUV, TLC, and CCC. Its products are exported to multiple global regions, with an off-peak lead time stated as within 15 workdays. Evidence is insufficient to assess after-sales service, customization, or customer cases. Innovation capability is supported by an R&D function and experienced...

Supplier typeThe supplier is legally identified as a limited company founded in 2010 and is described as a comprehensive manufacturer specializing in the design, production, and sales of power-supply products. However, the company nature is also recorded as a trading company, so the available records indicate manufacturing capability but do not establish that manufacturing is its sole business model.

CertificationsThe supplier reports ISO9001:2015, ISO14001:2015, and ISO45001:2016 management-system certifications. It also states that its products have approvals or certifications including CE, IEC, TUV, TLC, and CCC, providing explicit evidence of formal quality, environmental, occupational-safety, and product-compliance coverage.

R&D capabilityThe supplier describes dedicated design and R&D activity, an experienced technical team, more than 10 senior engineers in its company description, seven years of R&D-engineer experience in the supplied data, and advanced R&D, testing, and production equipment. These statements support an established technical function, but no patents, proprietary technologies, new-product launch record, or quantified R&D achievements are provided.

Production capacityThe supplier reports a 6,000 m² standard manufacturing plant, five production lines, 123 employees, 11–20 quality-control staff, and product output of 5,000 solar systems, 40,000 solar inverters, 10,000 solar charge controllers, and 10,000 solar generators annually. It also states an off-peak lead time within 15 workdays and access to Guangzhou, Foshan, and Shenzhen ports, providing explicit evidence of production and export-operational capability.
