What CQC certification means

With CQC mark certification, companies may apply the CQC mark to certified products to show that they meet the relevant quality, safety, performance and electromagnetic compatibility requirements, giving customers confidence. CQC certification helps companies in three ways:

1. Building the brand and competitiveness, providing a green pass to the market, raising market share and aligning economic and social benefit.

2. Controlling costs: CQC certification is widely recognised and accepted across industries, which reduces duplicate testing and certification and lowers operating costs.

3. Supporting sustainable development: CQC certification encourages companies to strengthen factory quality assurance and build modern enterprise systems for long-term growth.

NTEK solar, storage and charging division

NTEK's solar, storage and charging laboratory is equipped for high-power power electronics testing covering battery management systems, charging piles, photovoltaic inverters and residential and commercial storage systems. It can test electrical safety, EMC, environmental reliability, grid connection, communication protocols and interoperability, and meets international standards including IEC/EN 62477-1/-2, IEC 62109-1/-2, IEC 61000-6-1/-2/-3/-4, IEC/EN 61851-1/-23 and EN 50549, national standards GB 39752, GB 44263, GB/T 18487.1, GB/T 18487.2, GB/T 34657.1, GB/T 34658, GB/T 34131 and GB/T 34133, and industry standards NB/T 32004, NB/T 33008.1, NB/T 33008.2, NB/T 33001 and NB/T 33002.

Beyond testing and certification of solar, storage and charging products, we also provide operators with on-site testing, assessment, operation and maintenance services for electric vehicle charging stations, photovoltaic plants and solar-plus-storage systems.
