The CBLV 5120-B1 is a high-reliability lithium iron phosphate (LFP) energy storage battery, engineered for indoor applications with modular scalability. Adopting a 1P15S connection design, it supports up to 4 modules in parallel, flexibly expanding energy capacity from 4.8kWh to 19.2kWh to match diverse power demands.

Integrated with an advanced Battery Management System (BMS), the battery provides real-time monitoring of voltage, current, and temperature, plus multi-layer protection (over-voltage/under-voltage/over-current/over-temperature/short-circuit) for safe operation. It features natural heat dissipation, a compact 19-inch 3U rack-mount structure, and standardized interfaces for seamless integration with inverters via CAN/RS485 communication (Bluetooth optional).

With IP20 dustproof protection, 5000 deep charge-discharge cycles, and international certifications, the CBLV 5120-B1 delivers long-lasting, stable performance for residential, small commercial, and industrial auxiliary energy storage scenarios.
