Applications

Commercial & Industrial (C&I) Energy Management

Peak shaving, demand charge reduction, and backup power for factories, data centers, and retail facilities.

Renewable Integration

Stabilizing solar/wind power output and providing ancillary services for microgrids.

Critical Infrastructure

Uninterruptible power supply (UPS) for hospitals, telecom towers, and remote sites requiring high-altitude operation (up to 4,500m with derating).

EV Charging Buffering

Mitigating grid strain at high-power charging stations.

Key Highlights

Robust Safety Architecture

  • Four layers of protection — from cells to the full system — ensure maximum safety.
  • Early warning & suppression systems minimize fire risks and protect people on-site.
  • Explosion-proof design adds an extra layer of confidence for operators.

High-Efficiency Modular Design

  • Flexible capacity: modular packs allow easy scaling to meet different project sizes.
  • Smart thermal management keeps performance stable from -30°C to 55°C.
  • High efficiency means more usable energy and lower lifecycle costs.

Industrial-Grade Reliability

  • Built to endure: resistant to dust, humidity, and high altitudes.
  • Certified to global standards, ensuring compliance for international projects.
  • Long-lasting performance designed for demanding commercial and industrial use.
