Wholesale Supply: Modular Battery System | Commercial Energy Storage Cabinet | Global Delivery
Wholesale Modular Battery System for your commercial projects. Features Tier-1 LFP cells, liquid cooling, and EMS dispatch. Maximize ROI with turnkey global delivery & 10-year warranty.
Product Summary
Introducing the Modular Battery System (MBS), a high-density commercial energy storage cabinet engineered for industrial peak shaving, EV supercharging support, and micro-grid stabilization. Each system integrates Tier-1 LFP (LiFePO4) cells with an advanced liquid cooling loop, achieving over 6,000 cycle life @ 90% DoD and a 10-Year Performance Warranty. As a direct factory distributor, we provide turnkey PV-storage-charging hardware with global sea shipping and localized O&M support.
Why C&I Sourcing Chooses Modular Battery System
For project developers and charging infrastructure owners, the Modular Battery System delivers the lowest levelized cost of storage (LCOS) in its class. Key ROI drivers include: 92% round-trip efficiency, active cell balancing that reduces capacity degradation to <2% annually, and a scalable parallel architecture from 215kWh to over 2MWh per cluster. Our supply chain guarantees 15-day lead time for sample units and 45-day delivery for full container orders, backed by UL 9540A, IEC 62619, and UN38.3 certifications.
Product Overview & Safety Architecture
The Modular Battery System cabinet is built around a three-layer protection matrix: Cell-level fusing, module-level thermal runaway prevention, and cabinet-level aerosol fire suppression. The integrated Battery Management System (BMS) monitors 128 voltage points and 64 temperature sensors per rack, communicating via CAN/RS485/Modbus to any standard Energy Management System (EMS). The IP65-rated enclosure allows outdoor deployment in ambient temperatures from -20°C to 55°C without derating. Liquid cooling maintains cell delta-T below 3°C, directly extending calendar life to 15+ years.

Application Scenarios
EV Supercharging Stations & Fleet Depots
Integrate the Modular Battery System with on-site solar canopies and grid supply to reduce demand charges by up to 40%. Our bidirectional PCS supports simultaneous DC fast charging (CCS2/CHAdeMO) and grid feed-in. For micro-grids, the system performs black start and seamless islanding within 20ms.
Industrial Parks & Datacenters
Deploy as a turnkey peak shaving asset: schedule discharge during tariff peaks (e.g., 2pm–6pm) and recharge at off-peak rates. The built-in EMS logic supports demand response and frequency regulation (FCR, aFRR) with response times below 100ms.
Supply Assurance & Global Logistics
We operate a ISO 9001:2024 certified factory with annual output exceeding 3GWh. Every Modular Battery System undergoes factory acceptance testing (FAT) including insulation resistance, polarity, and full-load charge/discharge cycles. Shipping: 20ft/40ft HQ containers with anti-vibration pallets and moisture barrier packaging. Local O&M hubs are active in EU, NA, SE Asia, and MENA, offering 24/7 remote monitoring and 4-hour on-site SLA.
Frequently Asked Questions (B2B Procurement)
- What is the minimum order quantity (MOQ) for direct wholesale?
- MOQ is 4 units (≈860kWh) for standard branded cabinets. Sample orders (1 unit) are welcome with a 15% surcharge, refundable on the first container purchase.
- How does the 10-year performance warranty work?
- We guarantee ≥70% of nominal capacity after 6,000 cycles or 10 years (whichever comes first). Pro-rata replacement applies, including free local swap labor via our O&M partners.
- Can the Modular Battery System be paralleled for larger projects?
- Yes. Up to 10 cabinets can share a single EMS gateway using CAN bus communication, forming a 2.15MWh/1MW block. Additional blocks can be added via an external PLC controller.
- Which certifications are included for international deployment?
- Standard: UL 1973, UL 9540A (cell/module/unit), IEC 62619, IEC 62477, UN38.3, CE, and UKCA. For specific countries, we provide compliance support for CEC (Australia), VDE (Germany), and KC (Korea).
- What is the lead time for local O&M setup?
- For projects above 5MWh, we station a remote technician within 14 days and have a parts depot ready in 30 days. Our Predictive Diagnostics Cloud alerts you and our team before faults occur.
