Focusing on UPS, HVDC, and DC power panel systems, Acrel offers  DC and battery online monitoring solution that helps users identify risks early and achieve predictive maintenance.

① Battery Online Monitoring System

• Real-time monitoring of cell voltage, internal resistance, and temperature
• Precise identification of abnormal batteries, preventing “healthy string, failed cell” scenarios
• Trend analysis and early warning to detect performance degradation in advance

② DC Bus Electrical Parameter Monitoring

• Continuous monitoring of DC bus voltage and current
• Prevention of battery overcharge and over-discharge
• Rapid detection of load fluctuations, inrush currents, and potential internal faults

③ Centralized Monitoring and System Integration

• Support for standard protocols such as Modbus, TCP/IP, and SNMP
• Seamless integration with DCIM, EMS, and energy management platforms
• Unified monitoring and management of multiple UPS systems and battery cabinets

Typical Application Scenarios

• Data Centers: UPS and HVDC battery monitoring to enhance Tier-level reliability
• Power Systems: DC power panel and battery monitoring to ensure protection and control safety
• Telecom Facilities: Continuous operation assurance for core DC power systems
• Healthcare: Reliable power protection for critical loads such as operating rooms and ICUs

In critical infrastructure, batteries represent the last line of defense for power systems. Only by shifting monitoring from string-level to cell-level, and from reactive alarms to proactive early warnings, can power supply risks be effectively mitigated.

Through its DC and battery online monitoring solutions, Acrel provides an independent and reliable safety layer for UPS systems—helping users achieve higher power reliability, enhanced operational safety, and smarter maintenance management.
