Import 256v125a High Voltage Lifepo4 Bms For Bess Ups — Buy in wholesale FOB from Supplier in China

The RBMS07S2-3-125A256V from Hunan GCE Technology Co., Ltd. is a high voltage LiFePO4 Battery Management System designed for Battery Energy Storage System and UPS applications, supporting a nominal voltage range of 120V to 680V at a continuous rated current of 125A. The unit employs an MCCB plus contactor protection topology for robust DC-side fault isolation, with current sampling accuracy specified at 1.0 percent FSR. Communication interfaces include RS485 and CAN for UPS integration, CAN for BMU linkage, and Ethernet for monitoring software or Energy Management System connectivity. The BMS supports IAP firmware upgrade capability and optional HMI display with parameter configuration, with a 24VDC control supply spanning 18-28V and typical power consumption of 15W.

Construction centres on electronic components mounted on PCBs within a metal housing of steel or chassis-grade material, with the MCCB and contactor assembly forming the primary protection chain. The system can manage up to 13 BMUs, providing distributed cell monitoring for large-format LiFePO4 battery racks common in solar energy storage and industrial backup installations. Dry contact outputs, normally open, number up to three for external alarm or control signalling. The front-exit cable configuration and 15 kg net weight suggest rack-mount or cabinet-integrated installation rather than standalone enclosure deployment. Standard high voltage BMS platforms in the Chinese BESS supply chain typically conform to UL 1973, IEC 62619 or GB/T 34131 testing frameworks, though buyers must verify which certifications apply to this specific model.

Target customers include OEM integrators, BESS pack assemblers, solar-plus-storage EPC contractors and UPS system distributors serving residential, commercial and utility-scale renewable energy markets. The voltage flexibility from 120V to 680V allows configuration across multiple string architectures, from smaller residential systems to larger commercial arrays. Buyers should confirm with Hunan GCE whether the DC start option for the high voltage power module is included or ordered separately, and whether tap centre or mid-line output configurations are required for their specific battery topology, as these are listed as not supported. Incoterms, lead times, warranty terms and MOQ are not stated and must be negotiated directly with the supplier at its Changsha Pilot Free Trade Zone address.

Hunan GCE Technology Co., Ltd. is located at Section 2, Renmin East Road, Changsha area, Pilot Free Trade Zone, China (Hunan) 410000, positioning it within a designated trade facilitation zone that may offer customs and logistics advantages for export-oriented manufacturing. The companys supplier tier is marked as imported and trust tier as harbour, with a zero percent response rate and zero average response hours recorded in available data. These signals suggest buyers should initiate contact through multiple channels and allow additional time for quotation and technical clarification. The company specialises in battery management systems for energy storage and UPS applications, with the RBMS07S2-3-125A256V representing its high voltage platform for LiFePO4 battery integration.

No information is provided about Hunan GCEs establishment year, factory floor space, number of employees, annual production capacity, revenue figures, named clients, or specific quality certifications held. The source description focuses on product specification rather than corporate history or market position. Buyers should request company registration documents, ISO 9001 or automotive quality system certifications, product test reports (UL, IEC, GB/T as applicable), and reference installations before qualifying the supplier for project procurement. The address in Changshas Pilot Free Trade Zone may facilitate export logistics, but inland location from coastal ports should be factored into freight planning and lead time estimates.
