Rack Mount BMS Battery Storage BMS Energy Storage BMS 240S768V 400A Battery Management System High Voltage BMS For UPS ESS Lifepo4 Battery

Tailored for heavy-duty industrial UPS backup power and large-scale rack-type lithium battery deployments, the GCE high-voltage RBMS serves as the core master controller to safeguard battery assets, regulate charge and discharge cycles, and deliver real-time cell monitoring. Powered by GCE's self-developed, mature BMS algorithm suite, this rack BMS guarantees stable continuous operation and multi-tier safety protection for high-voltage lithium energy storage systems deployed in demanding industrial environments.

This rack-mounted RBMS maintains reliable performance across a wide working temperature window from -10℃ up to 50℃. Such robust thermal tolerance makes it an ideal option for indoor industrial premises, data room standby power stations, and commercial energy storage facilities where ambient temperature fluctuates frequently.

With a 400A continuous rated working current and 768V nominal system voltage (240-series lithium battery stack), this unit fits perfectly for mission-critical uninterruptible power backup scenarios. It can run steadily within 0%-90% relative humidity (non-condensing), adapting to diverse indoor industrial cabinet installation environments.

Featuring an IP20 ingress protection rating, the RBMS provides effective defence against solid foreign particles for indoor cabinet integration. A full set of multi-layer protection logics mitigates common lithium battery hazards and extends the whole lifecycle of your high-voltage lithium battery assets.
