Product Details

Next-Generation 125kW / 261kWh Liquid-Cooled BESS for Commercial & Industrial Applications

The GYL-261 integrates high-density LFP 314Ah batteries, bidirectional PCS, precision liquid cooling, and intelligent cloud EMS into a compact IP54 enclosure. Built for peak shaving, demand response, backup power, and smart microgrid integration.

Why Choose the GYL-261 Liquid-Cooled Cabinet?

  • Safe & Reliable: Built-in AI early warning system paired with 3D multi-layer fire safety (detection, prevention, active ventilation, and aerosol fire suppression).
  • Extended Battery Life: Advanced liquid thermal management keeps cell temperature difference ΔT ≤ 5°C, significantly reducing cell degradation in extreme climates.
  • High Efficiency & Flexibility: Maximum conversion efficiency ≥ 90% with standardized DC voltage (728V–923V) and reserved interfaces for fast site deployment.
  • Intelligent Cloud O&M: Real-time remote Web/APP management, automated AI dispatch strategy to optimize power tariffs, and one-click OTA firmware upgrades.

The GYL-261 Liquid-Cooled Outdoor Integrated Cabinet is a high-efficiency 125kW / 261kWh all-in-one battery energy storage system (BESS) engineered for commercial, industrial, and microgrid applications.

Key Highlights: • Advanced Liquid Cooling: Maintains battery cell temperature difference ΔT ≤ 5°C for extended LFP lifecycle. • Proactive 3D Fire Safety: Integrated AI early warning, smoke detection, active ventilation, and fire suppression. • High Conversion Efficiency: Maximum system efficiency ≥ 90% with low THDi (< 2%). • All-Weather IP54 Cabinet: Operating range -30°C to +55°C, high wind, sand-dust resistance, and up to 4000m altitude deployment. • Smart Cloud Operation: Real-time Web/App monitoring, AI dispatch algorithms, and remote OTA upgrades.
