Product Features of the BESS Cabinet

Enclosed in a rugged IP54 protective structure, this BESS Cabinet leverages a smart bess energy management system to prioritize solar consumption and drastically reduce off-grid fuel reliance.

  • High-Capacity DC Storage: Integrates a 1P270S cell grouping, yielding 271kWh rated energy from robust 314Ah lithium modules.
  • Instantaneous STS Transfer: Executes grid-to-battery switching in <10ms via a 170kVA transfer switch, sustaining continuous AC power delivery to critical industrial loads.
  • Advanced MPPT Integration: Manages up to 120kW maximum power per tracker and an 850V maximum PV voltage, extracting peak solar yields across 4 independent tracking strings.
  • Broad AC Port Compatibility: Supports versatile output voltages including 3P/N/PE and 3P/PE (380V/400V/415V/440V/460V/480V) to match complex facility wiring configurations.
  • Parallel Expansion: Allows paralleling of up to 5 PCS units, enabling seamless capacity scaling for growing commercial microgrid demands.

Environmental & Operating Conditions

Engineered for harsh deployments, the unit operates efficiently from -30°C to +60°C (with thermal derating initiated above 45°C) and supports high-altitude installations up to 4000m. The integrated dry self-cooling mechanism maintains stability within 80% maximum relative humidity parameters.

Certifications & Safety Standards

Complying with rigorous global commercial codes, the system meets CE, IEC62619, and UN38.3 safety standards. It features an integrated aerosol fire module to actively suppress internal thermal anomalies and protect the battery clusters.

Commercial Applications utilizing the BESS Cabinet

Deploying this multi-mode integration hub ensures highly resilient power routing across critical infrastructures demanding a dependable BESS Cabinet.

Applications & Use Cases

  • Off-Grid Microgrids: Functions as an autonomous PV-ESS-Diesel On/Off-Grid All-in-One System, prioritizing renewable generation while actively minimizing diesel generator runtimes.
  • Industrial Peak Shaving: Acts as a robust photovoltaic energy storage system, charging during low-tariff hours and deploying stored DC reserves during peak demand to cut utility costs.
  • Remote Telecom Stations: Delivers continuous, clean AC power for isolated communication hubs facing frequent utility grid anomalies or complete disconnection.
