The supplier reports ISO9001, ISO14001, and ISO45001-related certifications, 20 R&D engineers, sample-based customization, and broad export coverage. However, after-sales capability and detailed customer references are not provided. Corporate descriptions refer to the wider Chisage group, so group-level employee and sales claims should not be treated as confirmed figures for the target entity.

CertificationsThe supplier reports ISO9001:2015 and ISO14001 certifications, while slice 5 also lists ISO45001:2018 certification under management-system certification. These records provide explicit evidence of management-system certification, although the slices do not provide certificate numbers, validity dates, or scope.

Production capacityReported annual output is 50,000 lithium battery packs, 10,000 hybrid inverters, and 10,000 off-grid inverters, supported by two production lines and fulfillment within 15 working days in both peak and off-peak periods. Quality resources include 11–20 quality-control staff, 100% finished-product inspection, documented inspection instructions, and raw-material traceability, indicating established production and control processes.

Customization capabilityThe supplier explicitly reports design-service capability for customization from samples. This supports sample-based customization, but the slices do not describe engineering scope, minimum order requirements, tooling, or customization lead times.

Client casesThe supplier states that it has not collaborated with Fortune 500 companies, so no such customer case is available. It does report an 80%–100% repeat-buyer preference, but no customer names, project examples, or independently verifiable case details are provided.
