ET-76.8V314Ah-HV High-Voltage Commercial & Industrial Lithium Battery Energy Storage System
Core Parameter Interpretation
The ET-76.8V314Ah-HV rack/cabinet energy storage system is a high-performance LiFePO4-based solution engineered for commercial and industrial (C&I) applications, featuring a modular architecture that delivers scalable power, exceptional reliability, and flexible deployment.
At its core, the system is built on premium Lithium Iron Phosphate (LFP) cell chemistry, a benchmark for safety in energy storage. This chemistry delivers outstanding thermal stability, high energy density, ultra-low self-discharge, and zero memory effect, with an integrated protective cut-off switch to further enhance operational security. The base module provides 24.12kWh of usable energy, a nominal voltage of 76.8V, and a capacity of 314Ah, housed in a compact footprint of 440*1063*242mm (W/D/H) with a weight of 205kg per unit.
A defining strength of the system is its fully modular, scalable design. Users can expand the system from 3 to 11 units in series, enabling system nominal voltages ranging from 230.4V to 844.8V, and total system energy spanning from 72.35kWh to 265.27kWh. This flexibility allows businesses to right-size their energy storage investment, starting with a smaller configuration and scaling up as energy demands grow, eliminating the need for premature over-investment.
In terms of operational performance, the system supports a recommended charge/discharge current of 160A (with a maximum of 200A), paired with a recommended 90% depth of discharge (DoD) and an industry-leading cycle life of 8,000 times. This exceptional durability is backed by a 5-year free warranty and an additional 5 years of dedicated technical support, ensuring long-term peace of mind for global users.
A standout selling point is its floor mounting design, equipped with 4pcs universal wheels for easy carrying and moving. This unique feature enables flexible on-site deployment, seamless relocation between work areas, and simplified maintenance without the need for heavy lifting equipment, addressing a critical pain point for businesses requiring dynamic energy storage solutions.
The system also integrates intelligent energy management and robust environmental adaptability. An advanced Battery Management System (BMS) monitors voltage, current, and temperature in real time, with intelligent charge/discharge power adjustment and remote monitoring via a built-in WIFI module. A forced fan cooling system, paired with a heat-dissipating shell, effectively reduces battery operating temperature, supporting stable operation in environments ranging from -10°C to 55°C. With IP20 ingress protection and full compliance with CE, UN38.3, and MSDS certifications, the system meets the strictest global safety and quality standards.
Mainstream Technology Comparison
Against the backdrop of a rapidly evolving C&I energy storage market, the ET-76.8V314Ah-HV system distinguishes itself from traditional lead-acid systems and high-voltage NCM (Nickel-Cobalt-Manganese) lithium alternatives through a combination of safety, durability, flexibility, and total cost of ownership advantages.
Compared to traditional lead-acid energy storage systems, the ET-76.8V314Ah-HV delivers transformative performance improvements. Lead-acid systems are limited by a short cycle life of just 1,500 to 3,000 times, requiring frequent replacements that drive up long-term costs, while their bulky design results in a large footprint and fixed installation that offers no deployment flexibility. In contrast, the LFP-based ET-76.8V314Ah-HV boasts a 28,000-cycle lifespan, nearly 10 times that of lead-acid, with a far higher energy density that reduces space requirements by up to 70%. The universal wheel-equipped floor mounting design further enables easy relocation, a capability entirely unavailable with lead-acid systems. Additionally, the LFP chemistry eliminates the risk of acid leakage and thermal runaway, delivering vastly superior safety, while the 5-year full warranty and 5-year technical support far exceed the 1-2 year coverage typical of lead-acid solutions, resulting in a dramatically lower total cost of ownership over the system’s lifecycle.
When compared to high-voltage NCM lithium systems, the ET-76.8V314Ah-HV excels in safety, durability, and practical deployment. NCM systems offer marginally higher energy density but suffer from inherent thermal instability, creating a significant risk of thermal runaway and fire in industrial environments, with a cycle life of only 6,000 to 10,000 times—less than a third of the ET-76.8V314Ah-HV’s 28,000 cycles. NCM systems also require fixed rack-only installation, with no option for mobile deployment, while the ET-76.8V314Ah-HV’s wheeled floor mount design enables flexible, on-demand relocation. The LFP chemistry of the ET-76.8V314Ah-HV also delivers ultra-low self-discharge, outperforming the 3-5% monthly self-discharge of NCM systems, and ensuring long-term reliability for backup power applications. For C&I users prioritizing safety, long-term durability, and deployment flexibility, the ET-76.8V314Ah-HV represents a far more practical and cost-effective choice.
Scenario-Based Selection Guide
The ET-76.8V314Ah-HV system is engineered to meet the diverse energy storage needs of global commercial and industrial users, with tailored configurations optimized for specific operational scenarios.
For small and medium commercial facilities, including retail stores, office buildings, and small warehouses, a 3 to 5-unit series configuration (delivering 72.35kWh to 120.58kWh of energy, with voltages from 230.4V to 384V) is the ideal solution. These environments require reliable peak shaving to reduce time-of-use electricity costs, backup power for critical loads during grid outages, and flexible deployment for temporary operations. The compact modular design and universal wheels enable easy installation in limited indoor spaces, while the LFP chemistry ensures consistent, long-lasting backup power that minimizes downtime costs. The intelligent BMS and remote monitoring also simplify system management for businesses with limited in-house technical resources.
For medium industrial sites, such as manufacturing workshops, data centers, and cold storage facilities, a 6 to 8-unit series configuration (providing 144.69kWh to 192.92kWh of energy, with voltages from 460.8V to 614.4V) delivers the high power and 24/7 reliability required for heavy industrial loads. These scenarios demand robust energy management for demand charge reduction, TOU arbitrage, and uninterrupted power for mission-critical operations. The scalable high-voltage architecture of the ET-76.8V314Ah-HV supports the high power output needed for industrial equipment, while the BMS system optimizes charge/discharge cycles to maximize electricity cost savings. The forced fan cooling system ensures stable performance in high-temperature industrial environments, and the wheeled design enables easy reconfiguration as production layouts evolve.
For large-scale C&I projects, including logistics hubs, microgrids, and renewable energy integration sites, a 9 to 11-unit series configuration (delivering 217.04kWh to 265.27kWh of energy, with voltages from 691.2V to 844.8V) provides the high-capacity energy storage required for grid stability and large-scale renewable integration. These scenarios demand massive energy storage to support peak shaving for large facilities, stabilize microgrid operations, and store excess solar or wind energy. The 11-unit maximum configuration of the ET-76.8V314Ah-HV delivers 265kWh of usable energy, making it ideal for large-scale renewable energy projects, while the remote WIFI monitoring enables centralized management for multi-site operations. The system’s modular design also allows for phased expansion, enabling businesses to scale their energy storage capacity alongside growing renewable energy generation.
For temporary and mobile deployment scenarios, including construction sites, event power, and emergency backup, a 3 to 6-unit series configuration (providing 72.35kWh to 144.69kWh of energy) is the optimal choice. These environments require easy transport, rapid deployment, and reliable off-grid power, and the floor mounting design with 4 universal wheels is a transformative advantage, enabling quick relocation between sites without heavy lifting equipment. The LFP chemistry delivers consistent, long-lasting power in remote or off-grid locations, while the compact modular design fits easily into temporary worksites, making the system an ideal solution for mobile and emergency energy needs.
