Materials & System Integration
Container Enclosure
Standard ISO 20ft or 40ft high cube containers with CORTEN weathering steel frames. Internal and external surfaces are coated with anti-corrosion paint, achieving IP54 / NEMA 3R protection rating.
Battery System
Lithium iron phosphate (LFP) or nickel cobalt manganese (NCM) cells are adopted. Battery modules are framed with aluminum alloy, while battery racks adopt plug-in structures for convenient capacity expansion.
PCS Module
Built with IGBT or SiC power semiconductors. Grid-tied operation complies with IEEE 1547, and off-grid mode supports black start capability.
Thermal Management System
Combined cooling solution of variable-frequency air conditioning and liquid cooling. The battery compartment temperature is maintained between 20℃ and 35℃, and the PCS compartment ranges from 30℃ to 55℃.
Core Advantages
1. High integration level: Compared with conventional split-type energy storage systems, it cuts land occupation by half, reduces on-site construction workload by 70 percent, and shortens the whole construction cycle to less than one week.
2. Full North American standard compliance: Electrical interfaces, communication protocols and protection coordination meet UL 1741, IEEE 1547, NFPA 855 and other regional codes, allowing barrier-free market access in the United States.
3. Intelligent dispatch capability: The EMS is embedded with AI scheduling algorithms to support multiple operational modes including peak-valley arbitrage, demand response management, dynamic capacity expansion, frequency regulation and voltage support.
4. Multi-layer safety redundancy: Five tiers of safety protection are implemented at cell, module, rack, compartment and system levels. The fire suppression system adopts a dual agent combination of aerosol and perfluorohexanone.
5. Modular expandable design: Each standard module is rated 100kW / 200kWh, and multiple units can be paralleled flexibly to scale up to MW and MWh levels.
Application Scenarios
- New energy paired storage: PV-storage and wind-storage systems to smooth power output fluctuations
- Commercial & industrial energy storage: Peak-valley arbitrage, peak demand control and backup power supply
- Microgrid projects: Island microgrids, remote area power supply and military base power systems
- Grid-side energy storage: Frequency regulation, peak shaving, spinning reserve and black start service
Packaging & Transportation
Full-container delivery
A complete 20ft container weighs approximately 18 to 22 tons, while a 40ft unit weighs 28 to 35 tons. Transport options include trucks, rail freight and container ships.
Secure transit fixing
ISO standard corner castings are fitted at four corners of the container for firm locking onto transport vehicles; the allowable tilt angle during transit shall not exceed 15 degrees.
Post-delivery inspection
Upon arrival, inspect the container exterior and sealing performance, and verify battery voltage (no less than 95% of pre-shipping voltage). For long-term storage, battery balancing charging shall be conducted once every three months.
FAQ
Q1: Is grid interconnection approval mandatory for American-style integrated energy storage systems?
A: Yes. In the United States, energy storage equipment must pass IEEE 1547 certification and obtain interconnection approval from local utility companies. Fire safety inspections are additionally required in certain states, such as Title 24 compliance in California.
Q2: What disposal solutions are available when batteries reach end-of-life?
A: When the state of health (SOH) of LFP batteries drops below 80%, secondary utilization can be carried out for low-speed electric vehicles and communication base stations. At the final disposal stage, hydrometallurgy technology recovers valuable metals including lithium, cobalt and nickel.
Q3: How does the PCS realize harmonic suppression?
A: The PCS adopts a four-quadrant converter integrated with active power filter (APF) functions. It detects grid harmonics in real time and provides dynamic compensation, keeping total harmonic distortion (THD) below 3% in line with IEEE 519 requirements.
