The CGBC-350-HWD Base Coordinator Unit (BCU) aggregates reading logs, records battery performance, and manages alarm parameters via a built-in CONVERGE™ web interface. The BCU also seamlessly integrates with UNITE™ Battery Asset Management Software via MQTTS for centralized network-wide data reporting. Hard-wired battery sensors ensure uninterrupted communication for robust real-time data collection.\u003c\/p\u003e\n\u003cp\u003eInstead of relying on periodic spot checks, the CELLGUARD™ system tests each battery's internal resistance at pre-determined intervals and presents the results as long-term trends. This automated data collection captures discharge events in high resolution—including battery voltage, string voltage, discharge current, and capacity—allowing engineers to identify failing units before uninterrupted power is compromised.\u003c\/p\u003e\n\n\u003ch3\u003eKey Features \u0026amp;
