JinkoSolar Holding Co., Ltd. announced that its Jinko ESS North American business unit has earned IEC 62443‑2‑4 certification from exida, a leading authority in industrial cybersecurity. The certification confirms that Jinko ESS follows a secure development lifecycle, incorporating threat modeling, risk assessment, secure supply‑chain practices, and controlled vulnerability management across its products and processes.
The certification is a key milestone for the company’s energy‑storage segment, which shipped 3.3 GWh of systems in the first nine months of 2025. That figure represents a 10 % increase over the 3.0 GWh shipped in the same period of 2024, underscoring the segment’s rapid growth and JinkoSolar’s ability to scale its high‑margin offerings. The certification also positions Jinko ESS to meet the stringent security requirements of utilities, data‑center operators, and other high‑risk customers in the U.S. and Europe, where compliance with IEC 62443‑2‑4 is often a prerequisite for procurement.
Jeff Juger, U.S. Managing Director of Jinko ESS, said, “Cybersecurity is not simply a department at Jinko ESS. It is a foundational design principle.” Michael Medoff, Director of Certification at exida, added that Jinko ESS has proven rigorous system integration and maintenance processes, giving customers confidence that security is ingrained in the service lifecycle. The certification is expected to accelerate customer adoption, support higher margin targets for the ESS business, and reinforce JinkoSolar’s strategy to diversify beyond its core module operations.
The achievement also signals JinkoSolar’s commitment to embedding security into its energy‑storage solutions, a critical differentiator in a market where grid‑connected systems are increasingly targeted by cyber threats. By meeting IEC 62443‑2‑4, Jinko ESS can demonstrate to regulators and end‑users that its systems are designed to resist cyber attacks, potentially expanding its market reach in regions where stringent security standards are mandatory.
