Additionally, the system meets rigorous industry standards, including GB/T36276 and GB/T34131 certifications, ensuring compliance with global safety and performance benchmarks.

Beyond raw performance, the YTPower5015kWh addresses the unique pain points of industrial users. Many facilities struggle with inconsistent power quality (e.g., voltage fluctuations) or high peak electricity costs; this system mitigates these issues by storing energy during off-peak hours (when rates are low) and releasing it during peak demand, while also providing grid stabilization support. For renewable energy projects (such as solar farms or wind parks), it solves the intermittency problem by capturing excess energy generated during high-production periods and delivering it when output drops—boosting the utilization rate of clean energy sources by up to 30% in real-world applications.

What truly sets the YTPower5015kWh apart is its holistic approach to industrial energy management. It combines hardware excellence with intelligent software: an AI-powered Battery Management System (BMS) continuously monitors cell health, predicts maintenance needs, and optimizes charging/discharging cycles to prevent degradation. This not only reduces the risk of unplanned downtime but also extends the system’s cycle life to ≥6000 times (tested under 25±10℃, 90% depth of discharge (DOD), and 80% end-of-life (EOL) capacity retention)—a lifespan that outperforms many competitors by 15-20%. For industrial operators, this translates to lower total cost of ownership (TCO) and a faster return on investment (ROI), typically achieved within 3-5 years for most applications.

Product Features

Safety & Reliability: Industrial-Grade Protection

Safety is non-negotiable in industrial energy storage, and the YTPower5015kWh is designed with a multi-layered defense system to safeguard assets, personnel, and operations.

LFP Cell Technology for Inherent Stability

The system’s foundation—3.2V-314Ah LFP cells—is chosen for its chemical stability. Unlike other lithium-ion chemistries, LFP cells have no cobalt, reducing the risk of thermal runaway even in extreme conditions (e.g., overcharging, short circuits). This inherent safety is reinforced by rigorous cell testing, including temperature cycling, vibration, and impact resistance, ensuring consistent performance across the system’s lifespan.

Precision Liquid Cooling for Temperature Control

Traditional air-cooled systems often suffer from hotspots, which accelerate battery degradation and increase safety risks. The YTPower5015kWh’s liquid cooling system circulates a water-glycol mixture to maintain battery temperatures within a narrow, optimal range: 0~50℃ for charging and -20~55℃ for discharging. This precision (temperature uniformity of ±2℃) not only prevents overheating but also reduces energy loss from cooling by 30-40% compared to air-cooled alternatives.

Comprehensive Fire Protection & Environmental Resilience

To address worst-case scenarios, the system includes a perfluorohexanone + water fire protection system (with optional S-type aerosol or HFC-227ea alternatives), designed to suppress fires quickly without damaging equipment. It also features IP55 ingress protection (shielding against dust and water jets), C4 corrosion resistance (suitable for coastal or industrial environments with high humidity), and Level II lightning protection—ensuring reliable operation in harsh or unpredictable conditions.

Efficiency & Scalability: Optimized for Industrial Needs

Industrial sites require solutions that adapt to changing energy demands and fit within existing infrastructure—and the YTPower5015kWh delivers on both fronts.

High Energy Density & Space Efficiency

With a 5.015MWh capacity packed into a 20-foot HQ container (dimensions: 6058×2438×2896mm) and a weight of ~41 tons, the system offers exceptional energy density. Its <15㎡ footprint means it can be installed in tight spaces (e.g., factory yards, renewable energy project sites) without requiring extensive site modifications—a key advantage over bulkier, non-containerized systems.

Modular Design for Flexible Scaling

The YTPower5015kWh is built with modularity in mind: individual battery clusters, power distribution units, and cooling components can be easily expanded or upgraded. For example, operators can scale capacity from 5.015MWh to 10MWh+ by linking multiple containers, adapting to growing energy needs (e.g., a solar farm expanding its output or a factory adding new production lines). This modularity also simplifies maintenance—failed components can be replaced without shutting down the entire system, minimizing downtime.

Low Operational Costs & High Energy Retention

Efficiency directly impacts TCO, and the YTPower5015kWh excels here. Its ≤0.5C charge/discharge ratio ensures slow, steady energy transfer that reduces battery stress, while the liquid cooling system cuts cooling 能耗 by 30-40%. Additionally, the system maintains an energy retention rate of >90% over 24 hours—meaning minimal energy loss when storing power for off-peak use. For industrial users, this translates to lower electricity bills (via peak shaving) and reduced maintenance costs (via longer component life).

Smart Operation & Maintenance: AI-Driven Convenience

Industrial operators need solutions that require minimal oversight—and the YTPower5015kWh’s smart features deliver on this.

AI-Powered BMS for Predictive Management

The system’s Level 3 BMS uses artificial intelligence to monitor every cell in real time, tracking metrics like voltage, temperature, and capacity. It predicts battery degradation with >90% accuracy, alerting operators to potential issues (e.g., a failing cell) before they cause downtime. For example, if the BMS detects a cell operating outside optimal parameters, it automatically adjusts charging/discharging to protect it, then sends a notification for proactive maintenance. This predictive approach reduces unplanned downtime by 80% compared to systems with basic BMS.

Self-Healing & Self-Balancing Capabilities

Unlike traditional systems that require manual cell balancing (a time-consuming, labor-intensive process), the YTPower5015kWh features self-healing and self-balancing technology. It automatically equalizes charge across cells, preventing overcharging of individual units and ensuring uniform performance. This eliminates the need for on-site technicians to perform regular balancing, cutting maintenance labor costs by 50% annually.

Seamless Communication & Remote Monitoring

The system integrates with industrial control systems via CAN/Ethernet/RS485 interfaces and supports the Modbus TCP protocol, allowing operators to monitor and control it remotely (e.g., via a smartphone app or central control room). Real-time data—including energy storage levels, charging/discharging status, and maintenance alerts—is accessible 24/7, enabling quick decision-making. For multi-site operators (e.g., a utility company with multiple storage facilities), this centralized monitoring streamlines management and ensures consistent performance across locations.

Applications

The YTPower5015kWh’s versatility makes it suitable for a wide range of industrial and utility-scale applications, addressing unique energy challenges in each sector.

Renewable Energy Integration: Solving Intermittency for Solar & Wind

Renewable energy sources like solar and wind are clean but intermittent—output fluctuates with weather conditions (e.g., cloud cover, wind speed), making it difficult to integrate them into stable grid operations. The YTPower5015kWh solves this by acting as a “buffer” for excess energy, ensuring consistent power delivery.
In solar farms, for example, the system captures energy during midday (when sunlight is strongest and production exceeds demand) and releases it in the early morning or evening (when solar output drops but electricity use remains high). This not only prevents curtailment (the waste of excess solar energy) but also increases the farm’s revenue by selling stored energy during peak price periods. Real-world case studies show that solar farms using the YTPower5015kWh increase their renewable energy utilization rate by 20-30%, reducing reliance on fossil fuel backups.
For wind parks, the system addresses the variability of wind speeds: it stores energy during high-wind periods and delivers it when wind speeds drop, ensuring a steady flow of power to the grid. Additionally, the system’s 2500kW maximum charging/discharging power allows it to respond quickly to sudden changes in wind output, preventing voltage fluctuations that can disrupt grid stability. This makes it an ideal partner for offshore wind projects, where grid connection challenges are often more pronounced.

Industrial Peak Shaving & Load Management: Cutting Electricity Costs

Industrial facilities (e.g., manufacturing plants, data centers, cold storage facilities) face high electricity costs due to peak demand charges—fees imposed by utilities for using power during times of highest grid stress (typically 9 AM–5 PM on weekdays). The YTPower5015kWh reduces these costs via peak shaving: storing energy during off-peak hours (when rates are 30-50% lower) and using it to power operations during peak periods.
A large manufacturing plant, for instance, might use the system to store energy overnight (when production is low) and draw on that stored power during daytime shifts, when machinery and equipment are running at full capacity. By reducing peak demand by 20-40%, the plant can cut monthly electricity bills by 15-25%—a significant savings for facilities with high energy consumption.

The system also supports load balancing, smoothing out sudden spikes in energy use (e.g., when a large machine starts up). This prevents voltage drops that can damage sensitive equipment (e.g., automated production lines) and reduces the risk of downtime. For data centers—where even a few minutes of downtime can cost thousands of dollars—the YTPower5015kWh’s fast response time (<0.5s) ensures uninterrupted power, complementing backup generators and UPS systems.

Grid Stabilization & Resilience: Supporting Reliable Power Delivery

Utilities and industrial campuses often struggle with grid instability—caused by factors like fluctuating renewable output, aging infrastructure, or extreme weather—and need solutions to maintain voltage and frequency within safe limits. The YTPower5015kWh acts as a “grid stabilizer,” providing fast, flexible energy support to address these issues.
In remote industrial areas (e.g., mining sites, oil refineries) that rely on weak or isolated grids, the system serves as a backup power source during outages. Its 5.015MWh capacity can power critical operations (e.g., mine ventilation systems, refinery safety equipment) for 8-12 hours—enough time to restore grid power or start backup generators. This resilience is critical for industries where downtime poses safety risks or financial losses.

For utilities, the system supports ancillary services like frequency regulation: it injects or absorbs energy in response to small changes in grid frequency (e.g., caused by a sudden drop in power generation), keeping frequency within the 50/60Hz range required for stable operation. The system’s ≤0.5C charge/discharge ratio and fast response time make it well-suited for this role, helping utilities avoid costly penalties for grid instability.

Additionally, the system can support microgrids—local energy networks that power communities or industrial parks. In microgrids that combine renewable energy (e.g., solar + wind) with conventional generators, the YTPower5015kWh balances supply and demand, reducing reliance on fossil fuels and lowering carbon emissions by 25-35% compared to microgrids without energy storage.
