10ft Containerized ESS Turnkey System 384V 300Ah 115kWh Industrial Storage

The BEL-ESSC384300 is a fully integrated 384V 300Ah containerized Lithium Iron Phosphate (LiFePO4) energy storage system delivering 115.2 kWh of total capacity in a compact 10-foot ISO standard container format. Factory pre-commissioned and tested as a complete turnkey unit, this containerized ESS represents the fastest path to commercial energy storage deployment, eliminating the complexity, timeline uncertainty, and coordination challenges associated with on-site battery system assembly and integration. Simply position the container on a prepared concrete pad or compacted gravel base, connect the external PCS and grid interconnection, and the system is ready for commissioning within days rather than months.

Containerized energy storage has emerged as the preferred deployment model for commercial and industrial applications where speed to operation, installation simplicity, and future redeployment flexibility are prioritized. The BEL-ESSC384300 packages all battery modules, BMS controllers, thermal management, fire suppression, auxiliary power, lighting, and communication systems within a weatherproof, secure, and transportable ISO container that can be shipped via standard container logistics to any location worldwide. The factory integration approach ensures consistent build quality, comprehensive pre-delivery testing, and a single-point warranty, eliminating the finger-pointing that can occur between separate battery, enclosure, and integration contractors in traditional on-site builds.

• Containerized Turnkey Solution: Every BEL-ESSC384300 arrives on site as a complete, factory-tested energy storage system. The 10ft ISO container houses all battery modules, power distribution, BMS, HVAC cooling, aerosol fire suppression, internal lighting, auxiliary power supply, and communication gateway. External connections are limited to the DC power cables to the PCS, the grid connection for auxiliary power, and a communication cable for remote monitoring, dramatically simplifying on-site installation.
• 115 kWh Commercial Capacity: With 115.2 kWh total stored energy and 103.7 kWh usable at 90 percent depth of discharge, a single BEL-ESSC384300 provides meaningful storage for a wide range of commercial applications. For larger installations, multiple containers can be deployed in parallel on a common AC or DC bus, scaling to megawatt-hour class storage farms while maintaining the simplicity of standardized containerized modules.
• Integrated Environmental Control: The container includes a dedicated HVAC system with heating and cooling capability, maintaining internal temperatures within the optimal 15°C to 30°C range regardless of external conditions from -30°C to 50°C. Redundant fans and automatic failover ensure continuous thermal management even in the event of a single fan or compressor failure.
• Comprehensive Safety Systems: Multi-layer safety protection includes cell-level fusing, module-level DC contactors, system-level DC circuit breakers, aerosol-based automatic fire suppression with smoke and heat detection, emergency stop buttons at all access points, gas venting for pressure equalization, and IP65-rated container construction providing protection against dust, rain, and water jets from any direction.
• Remote Monitoring and Diagnostics: The integrated communication gateway provides 4G cellular and Ethernet connectivity to the BEL Energy Cloud platform, enabling real-time monitoring of all system parameters, automated alarm notifications via SMS and email, remote firmware updates, and performance analytics. On-site HMI touchscreen provides local status display and basic control functions for maintenance personnel.

The BEL-ESSC384300 containerized ESS is purpose-engineered for commercial, industrial, and utility-scale applications where rapid deployment, installation simplicity, and future flexibility are critical. Primary use cases include commercial and industrial behind-the-meter storage for peak shaving, solar self-consumption, and backup power at facilities without available indoor space for battery installation, construction and mining site temporary power solutions where containerized storage can be relocated as project needs evolve, remote community and island microgrid projects where containerized systems simplify logistics and commissioning compared to on-site assembly, utility-scale storage farms built from standardized containerized modules for rapid capacity expansion, and diesel generator displacement projects where containerized BESS reduces fuel consumption and emissions by enabling generators to operate at optimal load rather than following variable site demand. The standard ISO container format also enables cost-effective international shipping and simplified customs clearance compared to non-standardized battery enclosures.

Each BEL-ESSC384300 completes a comprehensive factory acceptance testing protocol before dispatch. Testing includes individual cell grading and matching to within 2 percent, module-level charge-discharge cycling at rated capacity, complete system integration testing with all subsystems operating simultaneously, full-power charge-discharge testing at 300A rated current, BMS redundancy failover testing, HVAC performance verification across temperature extremes, fire suppression system functional testing, communication system verification across all interfaces, and 7-day continuous unattended operation with automated monitoring and data logging. The container is shipped as a complete unit via standard container logistics, secured with GPS tracking, shock and tilt indicators, and remote condition monitoring during transit. On-site commissioning is typically completed within 3-5 working days. BEL provides a standard 5-year system warranty with comprehensive O&M service agreements available including 24/7 remote monitoring, scheduled preventative maintenance visits, and guaranteed performance metrics.
