From April 1–3, 2026, the 14th Energy Storage International Summit & Exhibition (ESIE) was held at the Beijing Capital International Exhibition & Convention Center.
 

Nader showcased a full matrix of solutions covering centralized, string-type, and residential energy storage, as well as core DC products. Focused on technological innovation and the development of new-type power systems, Nader supports the implementation of the national "Dual Carbon" strategy. With robust power distribution technologies, Nader empowers a low-carbon future through energy storage.

Nader's centralized energy storage solution targets large-scale power energy storage projects, providing high-performance, highly reliable core power distribution components.

The exhibited NDG3VH series DC disconnect switch withstands 30 kA fault current without failure before the fuse clears the fault.The NDZ3AT‑HB series DC contactor can break up to 4In fault current and withstand 40In short‑circuit shock, meeting the gold standard for high‑voltage box protection.The NDW3‑4000H AC air circuit breaker (ACB) features an ultra-high breaking capacity of 85 kA, suitable for parallel operation of 3.45 MW energy storage PCS units. The extreme performance of these core products lays a solid hardware foundation for the safe and stable operation of large-scale energy storage projects.

To meet the flexible deployment demands of string-type energy storage systems, Nader's solution balances high performance and space optimization. In addition to the NDG3VH series DC disconnect switch and NDZ3AT‑HB series DC contactor, the solution integrates the NDMNZ‑V and NDM3Z‑V series DC molded case circuit breakers (MCCBs). Adopting a compact 2P design, they offer a maximum breaking capacity of 25 kA, ideally suited for parallel battery clusters in 4‑hour energy storage systems.

The NDM3A series AC MCCB delivers industry-leading breaking performance of 60–80 kA, supporting up to 7250 kVA double-winding transformers. All products carry authoritative certifications including 3C, CE, TUV, and UL, ensuring reliable and safe operation of string-type energy storage systems.

Designed for the civil energy transition, Nader's residential energy storage solution offers comprehensive safety and intelligence. The NDB2NZ series DC miniature circuit breaker (MCB) features a compact 2P structure with high performance, breaking fault current up to 2.5 kA.The NDZ3W series DC contactor has non-polarized main contacts, enabling intrinsically safe breaking of bidirectional current.

 

The NDG3V‑50(U) PV DC switch satisfies high-power MPPT multi-string PV input requirements.The NDB5E TP‑C series smart MCB supports Class 1 energy metering, with RS485/Wi‑Fi/4G communication and remote control, fully meeting diverse demands for residential PV energy storage and intelligent power distribution.

These products support 30‑year service life in energy storage systems and are widely applied in the main PCS circuits of 5 MWh energy storage systems. They effectively reduce short‑circuit current stress under extreme conditions, minimizing risks of welding, fire, and explosion.

 

At this exhibition, Nader established full-scenario energy storage power distribution capabilities with three major energy storage solutions + core DC products, covering large-scale power stations to residential applications. With robust products and technological innovation, Nader safeguards power security and accelerates the large-scale development of the energy storage industry.
 

Going forward, Nader will continue to deepen the energy storage sector, advance the construction of new-type power systems with professional power distribution solutions, and continuously empower the achievement of China's "Dual Carbon" goals.
