Frequently Answered Engineering Inquiries

Direct engineering protocols regarding containerized architectures, cell chemistries, grid interconnection standards, and warranty frameworks.

To generate an accurate BESS dimensioning simulation, our engineering desk requires five foundational parameters:

  • Rated Power & Energy Capacity: Target MW and MWh (or desired duration: e.g. 2h, 4h, or 6h).
  • Point of Interconnection (POI) Voltage: Typically 11 kV, 33 kV, 66 kV, or 132 kV grid connection.
  • Application Profile: Peak shifting, transmission congestion relief, solar curtailment reduction, or frequency regulation.
  • Ambient Site Conditions: Minimum/maximum ambient temperatures, humidity, and elevation above sea level.
  • Duty Cycle Frequency: Daily cycle count (e.g. 1.0 or 1.5 equivalent full cycles per day at 80% DoD).

For standard containerized configurations utilizing our 5 MWh DC Liquid-Cooled Battery Block or modular C&I cabinets, our engineering desk delivers preliminary Single-Line Diagrams (SLD), site layout footprints, and budgetary techno-commercial models within 24 to 48 business hours following submission.

Yes. Senterra engineers turnkey solutions for both topologies:

  • AC-Coupled Topologies: Ideal for standalone grid-scale BESS, brownfield retrofits, and microgrids. Each block couples through dedicated bi-directional Power Conversion System (PCS) skids and MV step-up transformers.
  • DC-Coupled Topologies: Optimized for co-located solar-plus-storage projects to eliminate duplicate inverter stages, reduce clipping losses, and achieve lower overall balance-of-plant (BOP) capital expenditure.

Our flagship 5 MWh container incorporates dual independent active liquid chilling loops (2x 45 kW) circulating glycol-water coolant directly through cold plates between high-density prismatic LiFePO₄ cells. This active thermal architecture keeps cell-to-cell thermal variance strictly within ±2.5°C across the entire 20ft enclosure, preventing thermal runaway and degradation hot spots even in high ambient Indian desert climates.

Senterra Energy backs all utility and C&I installations with bankable 10 to 15-year performance warranties. This includes:

  • Capacity Retention Guarantee: ≥ 70% retention at 6,000 to 8,000 equivalent full cycles (80% DoD).
  • System Availability Guarantee: ≥ 98% operational uptime backed by cloud SCADA edge monitoring.
  • Round-Trip Efficiency (RTE): Guaranteed AC-to-AC round-trip efficiency of ≥ 88% throughout the operational warranty lifecycle.
