What this product is

What this product is

Architecturally, the SMU02C is powered by a high-performance 32-bit embedded industrial microprocessor that integrates dual isolated RS485 transceivers, a high-speed CAN bus network interface, an auto-negotiating 10/100M Fast Ethernet MAC/PHY, and precision multi-channel ADC telemetry circuits. Its northbound interface communicates natively via SNMP v3, HTTPS, and Modbus-TCP to Huawei NetEco or third-party OSS platforms, while its southbound interface commands rectifiers and intelligent lithium battery units (ESM) in compliance with IEC 60950-1, EN 55032 Class B, and Telcordia GR-1089.

What problem it solves

The SMU02C eliminates catastrophic field failures such as thermal runaway in battery strings, unmanaged low-load rectifier energy waste, silent communication blackouts, and uncoordinated load disconnects during deep power grid anomalies. Its deterministic SOC/SOH estimation, automated temperature compensation, and programmable battery low voltage disconnect (BLVD) and load low voltage disconnect (LLVD) safeguards preserve battery longevity and ensure uninterrupted telecom payloads.

Who and where it is for

Engineered for 5G/4G macro cell site power systems, central office DC distribution plants (e.g., TP482000B, TP483000D), indoor/outdoor integrated micro-power cabinets (ETP48200/ETP48400), and hybrid solar-diesel-grid telecommunication infrastructure.
