500kWh / 250kW Containerized Battery Energy Storage System is a 500 kWh lithium iron phosphate energy storage platform rated 250 kW for commercial and industrial applications. The 500 kWh / 250 kW system is a complete containerised platform with battery, PCS, thermal management and EMS in a single 20-foot enclosure. It is configured for grid-tied, behind-the-meter or hybrid operation.
Cells, Modules & BMS
The system is built from 375Ah prismatic LiFePO4 cells in 1P416S modules with a three-level (BMU / BCU / BAU) BMS architecture. Protection covers cell and module over-voltage, under-voltage, over-current, over-temperature, insulation fault and short circuit. Communication uses CAN / RS485 / Ethernet (Modbus TCP, IEC 61850 optional) for EMS, SCADA and cloud platform integration.
Thermal Management & Safety
Liquid cooling with redundant circulation pumps maintains cell temperature uniformity and allows continuous 0.5C operation in high-ambient sites. Multi-level fire protection is provided by perfluorohexanone suppression with multi-level gas, smoke and temperature detection, explosion-proof pressure relief and optional water-based backup. The enclosure is rated IP54.
Cycle Life & Performance
Cells are specified for more than 6,000 cycles at 80% depth of discharge, with a usable SOC window of 5% - 95% and round-trip efficiency of 89% - 91% (DC round-trip, 0.5C). The platform is expandable: additional containers can be paralleled on the AC or DC side to build multi-megawatt sites on one control architecture. Ambient operating range is -20C to +60C, with derating above 45C where required.
Charging & Grid Interface
DC nominal voltage is 1331.2V (416S) with a maximum continuous charge and discharge rate of 0.5C. The integrated 250 kW PCS operates grid-tied, off-grid or in diesel generator support mode, with reactive power capability and low-voltage ride-through functions. Operating modes include peak shaving, demand charge management, solar self-consumption and diesel generator support, scheduled through the EMS.
Mechanical & Installation
The unit is supplied as a 20-foot containerised unit with integrated PCS and EMS measuring 6058 x 2438 x 2896 mm. The container requires a level foundation, AC and communication cable routing, a site earthing grid and crane access. Commissioning follows the supplied installation manual, with remote support available.
Deployment Scenarios
Used for utility-side and behind-the-meter projects of 0.5-5 MWh, including solar-plus-storage plants, large factories and mines, island and microgrid systems, and diesel generator hybridisation programmes.
Customisation
Capacity, PCS rating, AC or DC coupling, protocol mapping and branding can be specified per project, and cabinet or container layouts can be adapted to site constraints.
Each system is factory-tested for capacity, insulation, communication and protection functions. Compliance target standards: UN38.3, IEC 62619, IEC 62933, CE and RoHS. Warranty: 10 years (5 years optional).
