The CTECHI ESS100KW/241KWh split-type energy storage system represents the high-capacity tier of CTECHI's split-cabinet product line, purpose-built for demanding commercial and industrial energy management. Leveraging 15 × 16S1P 314Ah LFP battery packs connected in series, the system achieves an industry-competitive 768V DC bus with 241kWh total capacity — providing ample headroom for full-day peak shaving cycles, demand response programs, and renewable energy time-shifting. The 100kW hybrid inverter delivers utility-grade power quality with < 2% THD and 0.99 power factor, making it suitable for direct integration into facility power distribution systems. Despite its large capacity, the split-type architecture preserves deployment flexibility: battery and PCS cabinets are independently positioned, and the modular battery rack design allows incremental capacity expansion. With intelligent air cooling, IP54 protection, and redundant communication pathways, the ESS100KW/241KWh is the definitive choice for energy-intensive operations seeking to reduce electricity costs and carbon footprint simultaneously.

The system adopts a 768V high-voltage architecture with 15 battery packs connected in series, achieving an efficiency "sweet spot" that minimizes DC current to approximately 130A. This advanced high-voltage design significantly reduces cabling requirements and CAPEX while ensuring seamless compatibility with 800V-class PV string inverters. With a wide operational voltage range of 648V to 876V and independent BMU monitoring for every pack, the system delivers superior conversion efficiency and rock-solid reliability for large-scale C&I energy storage and grid-forming applications.

At its core, a 100kW SiC-based hybrid inverter leverages advanced silicon carbide semiconductors to reach a peak efficiency of 98.5%. This compact, transformer-less power conversion system supports both grid-tied and off-grid operations with seamless dual-mode switching. It provides robust grid-support functions, including frequency regulation and voltage ride-through, while maintaining high power quality and precise four-quadrant power control to optimize your facility's energy utilization.

The modular rack-based battery design houses 15 high-capacity packs in a flexible, front-access configuration that eliminates the need for rear clearance, maximizing space utility in industrial settings. Featuring hot-swappable packs with blind-mate DC connectors and isolated CAN bus communication, the system allows for safe, localized maintenance and easy scalability without interrupting the entire system. Each rack includes independent DC disconnects and integrated smoke detection, ensuring a secure and uninterrupted power supply.

Safety is engineered at every level through a multi-tier protection framework, ranging from cell-level safety vents and ceramic-coated separators to system-wide earth fault monitoring and arc flash detection. The IP54-rated enclosure is equipped with intelligent door interlocks, emergency stops, and built-in smoke detectors. For mission-critical safety, the system supports optional per-rack aerosol fire suppression modules utilizing FK-5-1-12 clean agent, providing a robust defense against electrical and thermal risks.

The ESS100KW/241KWh is fully optimized for intelligent operation through a localized Energy Management System (EMS) featuring an intuitive 7-inch HMI touchscreen and seamless cloud connectivity via 4G, Wi-Fi, or Ethernet. Users can track real-time metrics such as SOC, SOH, and revenue through professional dashboards, while automated features like TOU scheduling and demand limit control prevent facility peak demand exceedance. With an open API for third-party VPP integration and 12-month high-resolution data logging, the system offers total visibility over industrial energy assets.
