The China Quality Certification Centre has authorized the Jinko ESS Testing Center as a WMT witnessed laboratory. This status allows the 7,000-square-meter facility to streamline certification processes for its battery energy storage systems.
Why it matters
Expanding internal testing capabilities allows manufacturers to accelerate product certification pathways in both domestic and overseas markets. This agility supports the deployment of large-scale renewable projects, such as the 220 MWh battery portfolio currently underway in Germany.
The Jinko Tera storage system provides a 5.01 MWh rating and a tested round-trip conversion efficiency of 94.1 percent. The system features a 20-year design life and delivers grid-forming capability over 10-second intervals.
The players
Jinko ESS
A developer of solar and battery energy storage technologies including liquid-cooled systems and power conversion equipment.
China Quality Certification Centre
A national certification body that manages electrical and energy product standards within China.
The details
The facility uses a WMT (Witnessed Manufacturer’s Testing) model, which enables the lab to work directly with certification bodies throughout the verification cycle. The 7,000-square-meter center employs over 500 high-precision instruments to conduct performance, electrical safety, and environmental adaptability testing for battery energy storage systems (BESS) and power conversion systems (PCS). Its 220 MWh German portfolio integrates this storage with photovoltaic capacity through hybrid power purchase agreements.
Timeline

20 years of design life for the Jinko Tera storage system.
The Tech Race
This development follows the facility's existing CNAS accreditation and aligns with international safety validation frameworks. It positions Jinko ESS to compete more aggressively by shortening the verification phase required for entry into markets like Germany and Africa.
The increased testing capacity aims to improve grid stability for renewable energy integrations. Commercial and industrial operators can expect faster equipment availability as the manufacturer clears certification bottlenecks for its 5.01 MWh storage units.
The takeaway
Direct certification access allows Jinko ESS to bring large-scale storage to market faster while maintaining rigorous grid-stability performance standards. Watch for the operational deployment status of the 220 MWh German project as an indicator of the company's scaling speed.
