It reports two factories, seven production lines, 87 employees including 24 engineers, 11–20 quality-control staff, and broad export coverage, with 90% of sales from exports. The supplier holds ISO 9001, ISO 14001, and OHSAS/OHSMS 18001 certifications. It states that it provides pre-sale field investigation and post-sale installation support, including commissioning and technical training. Reported lead times are within 15 workdays during off-peak periods and one month during peak periods. The available information supports production, service, certification, and customization strengths, but does not provide sufficient evidence of financial credibility or specific customer cases.

Supplier typeWonVolt is explicitly described as a Manufacturer/Factory and Group Corporation, with two factories in Hefei and a stated specialization in industrial and commercial energy-storage solutions. This directly supports classification as a manufacturing supplier rather than only a trading intermediary.

CertificationsThe supplier reports holding OHSAS/OHSMS 18001, ISO 9001, and ISO 14001 certifications. These stated management-system certifications provide explicit evidence of established occupational safety, quality, and environmental management systems.
