This high-density design eliminates the need for excessive on-site space, streamlining deployment for solar/wind farms, grid energy hubs and large industrial energy facilities—all while delivering a 0.5C charge/discharge rate for flexible energy dispatch and utilization.

🛡️ Industrial-Grade Safety & Global Compliance

Safety is engineered into every layer of the EPES5000, with a suite of robust protections and global industry certifications for utility-scale reliability:

• High-quality LFP cells: Delivers inherent thermal stability, long cycle life and resistance to thermal runaway—ideal for 24/7 utility-scale operation.
• NFPA 68&69 compliance: Meets the strictest fire protection standards for energy storage systems, mitigating fire and explosion risks.
• Multi-level fire suppression system: Features active warning, container-level aerosol suppression, PACK level immersion and water spray for comprehensive fire protection.
• IP55 (Battery Room) / IP54 (Electric Room) protection & C4 anti-corrosion rating: Ensures reliable performance in harsh outdoor, coastal and industrial environments, with resistance to dust, water and high-salt-fog conditions.

🌡️ Intelligent Liquid Cooling & Wide Temperature Adaptability

The EPES5000’s integrated liquid cooling & heating system maintains optimal battery temperature year-round, ensuring consistent performance and extending cell life even in extreme climates. Rated for an operating temperature range of -20℃ to 55℃, the container adapts seamlessly to cold northern regions, hot tropical areas and all temperate zones—eliminating performance derating from temperature fluctuations and ensuring stable energy output for grid stabilization and renewable integration.

🚀 Pre-Assembled Design & Effortless Deployment

As a fully pre-assembled, plug-and-play utility-scale solution, the EPES5000 is shipped factory-tested and ready to operate—dramatically reducing on-site installation time and labor costs. No complex on-site assembly is required; the container only needs basic grid and utility connections to start operation. It also features minimal maintenance requirements, with real-time monitoring capabilities that enable remote fault detection and troubleshooting—lowering total cost of ownership (TCO) for large-scale energy projects.

📊 Robust Grid Performance & Renewable Integration

Engineered to support the volatile power demands of modern energy grids, the EPES5000 stabilizes grid usage and enables seamless integration of solar, wind and other renewable energy sources. It stores surplus renewable energy during peak generation periods for dispatch during high-demand hours, reducing grid strain, curbing fossil fuel reliance and supporting global carbon neutrality goals. With a 0~97% depth of discharge (DOD), it maximizes energy utilization for grid arbitrage, peak shaving and grid auxiliary services—unlocking additional revenue streams for energy project operators.
