Nidec Conversion, a business of Nidec, will present ACBOX™ V4, DCBOX™ and UniQube™ at RE+ 2026 in Las Vegas. The company will showcase the technologies at booth C5454 in Central Hall at the Las Vegas Convention Center from 17 to 19 November 2026. Its new UniQube™ platform is engineered for energy storage systems with durations of two to eight hours, while its compact architecture delivers up to 20% higher power density compared with the stated market benchmark. Together, the portfolio places grid-forming capabilities, scalable power conversion and integrated system design at the centre of Nidec’s response to renewable integration and rising electricity demand.

Grid Reliability In Focus

The exhibition will provide a timely platform for Nidec Conversion to demonstrate how storage and power conversion equipment can respond to increasingly demanding grid requirements. The company positions the portfolio as a practical option for customers seeking to improve system performance while simplifying the deployment of energy storage at scale.

Its approach combines proprietary hardware and software developed in-house with manufacturing, system integration and project execution capabilities. This breadth is particularly relevant as energy infrastructure incorporates more renewable generation, storage capacity and high-power demand from data centres.

Michael Briggs, Chairman, Nidec Motion & Energy Business Unit, CEO, Appliance Automotive Division, said:

“Energy infrastructure is entering a new phase, where reliability, flexibility and the ability to integrate increasingly complex technologies are becoming essential,”

UniQube For Large Scale Storage

UniQube™ is Nidec’s new liquid-cooled power conversion system platform for large-scale energy storage applications. Its modular architecture allows flexible configurations for differing project requirements, offering an adaptable foundation for installations designed around storage durations from two to eight hours.

Designed for outdoor installation, the platform uses liquid cooling to support consistent performance in demanding environments, including high-temperature climates. Nidec states that the compact design can help customers optimise available space and simplify system integration, with up to 20% higher power density than the stated market benchmark.

The platform supports current 1500 V applications and is designed to accommodate the industry’s transition towards 2000 V systems. Beyond battery storage, its architecture can also support solar and hydrogen-related energy infrastructure, widening the range of potential uses for the conversion technology.

ACBOX V4 Strengthens Grid Support

ACBOX™ V4 is the latest version of Nidec’s integrated AC-block battery energy storage system architecture. The system is designed to support efficiency, reliability and scalability as grid requirements become more exacting.

Its distributed power conversion architecture incorporates silicon-carbide semiconductor technology, enabling more granular energy management and aiming to improve system efficiency and availability. Native grid-forming capabilities are intended to help storage systems contribute more actively to grid stability and resilience as renewable generation increases.

The platform also includes a cybersecurity-by-design approach and supply chain transparency considerations. These features address customer expectations surrounding system security, equipment sourcing and confidence in long-term operations.

Dominique Llonch, President, Nidec Motion & Energy Business Unit, shared:

“Customers need solutions that not only meet today’s technical requirements but also adapt as their projects and the grid evolve,”

Integrated Project Delivery

Nidec brings together regional engineering expertise, local project execution and long-term lifecycle services across the energy storage project lifecycle. This integrated model is designed to help customers manage project complexity while supporting reliable system performance over time.

At RE+ 2026, the company will show how ACBOX™ V4, DCBOX™ and UniQube™ can operate as part of a broader portfolio of energy storage and power conversion capabilities. The presentation reflects Nidec’s focus on connecting its technologies and expertise to support renewable integration, grid stability and higher power demand across modern energy infrastructure.

Dominique Llonch, President, Nidec Motion & Energy Business Unit, stated:

“ACBOX™ V4, DCBOX™ and UniQube™ reflect our commitment to practical innovation, combining advanced technologies with engineering expertise to help customers simplify integration, improve performance and support long-term operations. Together, these solutions demonstrate how Nidec is responding to evolving energy infrastructure needs, from renewable integration and grid stability to the growing power demands of data centers.”
