HT Infinite Power Launches Highvoltage Energy Storage System for Microgrids

As renewable energy penetration increases and demands for energy reliability and cost-effectiveness grow, efficient and flexible energy storage systems have become crucial technologies for enabling energy transition and ensuring stable power supply. The HT Infinite Power 100kW/200kWh high-voltage Battery Energy Storage System (BESS) offers an advanced solution for commercial users, data centers, and remote microgrids through its highly integrated design, exceptional performance, and scalable architecture.

Core Technical Advantages and Design Philosophy

The system represents more than a simple combination of power conversion systems (PCS) and battery racks. Its optimized integration delivers several key benefits:

• Integrated Power Conversion and Battery Management: The co-designed PCS and battery racks minimize interface losses, simplify installation, and improve overall energy conversion efficiency through optimized communication protocols and electrical connections.
• High-Voltage DC-Coupled Architecture: Operating at 614-633V nominal DC voltage, the system reduces cable losses and improves efficiency, particularly when directly coupled with DC-output renewable sources like solar PV.
• Modular Scalability: Both capacity (energy) and power can be expanded independently through parallel connections of additional battery racks or PCS cabinets.
• Compact Standardized Design: With standardized rack dimensions (550 × 776 × 1960 mm), the system adapts easily to technical rooms or containerized deployments.
• Robust Environmental Tolerance: Air-cooled with IP54 (PCS) and IP55 (battery) protection, the system operates reliably across wide temperature ranges (charging: 0–55°C; discharging: –20–55°C).
• Rapid Dynamic Response: With 100kW continuous output and 140A charge/discharge capability, the system responds quickly to grid fluctuations and load changes.

Detailed System Specifications

Operational Modes

Grid-Tied Mode

Stores excess grid power or renewable generation during low-demand periods for discharge during peak hours, reducing electricity costs through peak shaving.

Island Mode

Provides autonomous power supply during grid outages or in off-grid locations, with millisecond-level switching for critical load continuity.

Hybrid Mode

Intelligently coordinates PV generation, battery storage, and local loads through an Energy Management System (EMS), optimizing energy use and automatically transitioning between grid-connected and islanded operation.

Maintenance and Lifecycle Management

The system incorporates several features to ensure long-term reliability:

• Integrated Battery Management System (BMS): Monitors cell-level voltage, temperature, and state-of-charge while preventing overcharge/discharge and maintaining cell balance.
• PCS Self-Diagnostics: Detects and reports faults via Ethernet or CAN interfaces for rapid troubleshooting.
• Preventive Maintenance: Quarterly visual inspections of electrical connections, cable insulation, and ambient conditions are recommended.

Application Scenarios

The system demonstrates value across multiple use cases:

• Commercial Rooftop PV Integration: Smooths intermittent solar generation and increases self-consumption.
• Industrial Peak Demand Reduction: Lowers demand charges for warehouses and manufacturing facilities.
• Data Center Backup: Extends UPS runtime during outages for critical IT infrastructure.
• Microgrid Deployment: Serves as a turnkey solution for remote communities or emergency power needs.

Scalability Considerations

The system's expansion capabilities allow:

• Power Expansion: Adding parallel PCS cabinets increases output capacity.
• Energy Expansion: Connecting additional battery racks extends storage duration.

This modular approach enables phased investments aligned with evolving project requirements.
