Las Vegas, USA – 5 September 2025 – RCT Power announces the official market launch of CESS 4000, a C&I energy storage system with liquid-cooled intelligence designed to meet the demand for large scale energy storage.
The CESS 4000 delivers unprecedented value through:
▸Unmatched Capacity: scalable configuration (1-10 clusters) with the highest power density.
▸Liquid cooling boosts performance while cutting auxiliary power consumption.
▸Integrated container design – the lowest installation and lifecycle cost.
▸Effectively smooths the output from renewables and 90% curtailment reduction.
▸NFPA 69-compliant fan and ventilation systems.
▸Explosion Prevention/Fire Suppression/Gas Detection.
▸Dual-mode cooling (liquid + AC) ensures 24/7 stability for batteries and electronics.
▸An all-in-one EMS platform for self-optimizing energy strategies.
The CESS 4000 is a comprehensive solution system specifically engineered to address critical energy challenges across diverse sectors. It incorporates multiple innovative technological architectures, including an industry-leading 690V low-voltage grid connection solution and an integrated DC + Skid system, delivering adaptable modular design to meet a wide range of scenario-based demands.
In industrial applications, the system utilizes hybrid PV + storage + diesel configurations to provide stable power supply for fully automated production lines during peak electricity pricing periods, significantly reducing operational costs. For commercial use, it supports large retail chains in achieving 100% solar self-consumption, seamlessly integrates with EV charging networks, and accelerates the transition to zero-carbon operations. In grid-scale applications, it enhances grid stability, supports virtual power plant (VPP) aggregation scenarios and facilitates renewable energy integration with millisecond-level frequency response capabilities.
“The CESS 4000 sets a new benchmark for C&I energy storage and RCT Power with its advanced liquid-cooling system,” said Matt Doe, Director of Sales at RCT Power USA. “By integrating thermal innovation with NFPA-compliant safety and an intelligent EMS platform, we’re providing a solution that enhances grid stability, reduces demand charges, maximizes renewable utilization, and ensures mission-critical power reliability 24/7.”
Independent tests verify:
→ A battery degradation rate of less than 20% at an ambient temperature of 25℃-30℃.
→ 20% reduction in balance-of-system costs with containerized plug-and-play design.
→ Integrated intelligent EMS (Energy Management System) for real-time operational monitoring and carbon footprint tracking.
With the launch of the CESS 4000, RCT Power positions itself at the forefront of next-generation large-scale energy storage—empowering industries, retailers, and grid operators to explore the future of industrial energy.
