Brief introduction

Meta Description: EP Energy’s EPHS104/156L Hybrid ESS delivers 50kW/104kWh-156kWh liquid cooled energy storage with ultra-fast on/off-grid switching, 200% PV oversizing, and UL9540A safety—ideal for factories, hospitals, malls and more.

As commercial and industrial (C&I) energy demands grow more dynamic, businesses need flexible, efficient, and reliable energy storage solutions that adapt to grid fluctuations, maximize renewable energy use, and ensure uninterrupted power. EP Energy’s EPHS104/156L Hybrid ESS redefines C&I energy management with an all-in-one liquid cooled cabinet design, combining high-performance lithium iron phosphate (LFP) battery technology, intelligent energy control, and industry-leading safety features. Available in 50kW/104kWh (EPHS104L) and 50kW/156kWh (EPHS156L) configurations, this hybrid energy storage system is engineered for diverse commercial scenarios—from factories and hospitals to shopping malls, farms, and educational institutions—delivering seamless on-grid/off-grid operation, solar energy optimization, and reliable backup power.

Core Advantages: Efficiency, Flexibility, and Safety Redefined

The EPHS104/156L Hybrid ESS is built around four core design pillars, addressing the key pain points of C&I energy users: high energy costs, grid dependency, installation complexity, and safety risks.

📈 Unmatched Energy Efficiency & Solar Utilization

Powered by 314Ah high-density LFP cells, the system features a 200% PV oversizing design and a maximum 20A PV input current per string, perfectly matching high-power PV modules to capture and store every watt of solar energy. With a wide MPPT voltage range of 150–850V and a maximum PV input voltage of 1000V, it maximizes renewable energy self-consumption, reduces grid electricity reliance, and slashes operational costs for businesses. The liquid cooling system maintains optimal battery temperature, ensuring consistent efficiency even during long-term, high-cycle operation.

🔌 Extreme Flexibility for All Energy Scenarios

Designed for seamless on-grid/off-grid switching in <10ms—faster than the blink of an eye—the EPHS104/156L ensures critical loads stay powered during grid outages or instability, eliminating costly downtime for hospitals, data centers, and manufacturing facilities. It supports 100% unbalanced output, half-wave, and surge loads, adapting to the variable energy demands of commercial spaces.

Smart Load/GEN/INV ports enable flexible connection to multiple energy sources: grid-tied inverters, diesel generators, wind turbines, and more. The system is scalable up to 10 units in parallel, allowing businesses to expand energy storage capacity as their needs grow—no major redesign or installation required.

🛠️ User-Friendly, Plug-and-Play Installation

The EPHS104/156L features a 3-in-1 integrated design (battery, inverter, control system), factory-configured and fully tested for immediate on-site deployment. It requires no foundation for installation, significantly reducing construction time and costs, while its compact all-in-one cabinet saves valuable floor space for commercial facilities with limited room. Operating at <65dB, the system runs quietly, making it suitable for noise-sensitive environments like schools, hospitals, and residential communities.

🛡️ Industry-Leading Safety & Durability

Safety is at the heart of the EPHS104/156L design, with a suite of robust protections and international certifications:

• UL9540A certification: The gold standard for energy storage safety, preventing thermal runaway and fire spread.
• IP55/C4 protection rating: Dust-tight, water-resistant, and corrosion-proof, ideal for both indoor and outdoor installation in harsh environments (coastal, industrial, high-humidity areas).
• Wide operating temperature range: -25°C to 55°C, ensuring reliable performance in extreme cold and heat.
• Comprehensive fire suppression system: Equipped with smoke detectors, heat detectors, alarm sounders, aerosol fire extinguishers, and optional sprinklers, gas detectors, and exhaust systems for multi-level fire protection.
• Real-time monitoring: 24/7 battery status tracking to identify and mitigate risks before they impact operation.
