BlueESS 261kWh-125kW-400Vac-CE — Liquid-Cooled Energy Storage Cabinet

An all-in-one liquid-cooled energy storage cabinet with 261kWh capacity and 125kW power, built for fast on-site deployment and side-by-side expansion.

BlueESS 261kWh-125kW-400Vac-CE is an all-in-one liquid-cooled energy storage cabinet that integrates the battery system, power conversion, thermal management, and fire protection into a single unit that is factory pre-installed and pre-commissioned. Multiple cabinets can be installed side by side and operated in parallel to scale up system capacity, with local and cloud-based monitoring for remote operation and maintenance.

Key features

  1. Uses high-quality, carefully selected battery cells to help ensure system safety
  2. Multiple layers of electrical protection and fire-protection measures to enhance system safety
  3. Intelligent liquid cooling for efficient heat dissipation
  4. All-in-one, fully integrated system design with factory pre-installation and pre-commissioning to minimize on-site commissioning work
  5. Side-by-side, seamless installation with multi-unit parallel operation for system expansion
  6. Sub-3-second coordinated response; the EMS (Energy Management System) supports peak shaving and energy management across a range of scenarios, including dynamic capacity-expansion strategies
  7. Local and cloud monitoring work together to enable remote operation and maintenance
  8. Black-start capability for reliable operation in off-grid/micro-grid mode

Typical applications

Commercial & industrialBehind-the-meter energy storage for peak shaving and demand-charge management.Renewable integrationPaired with solar PV for self-consumption and grid-support functions.Off-grid / micro-gridBlack-start capable operation for remote or backup power scenarios.
