How it connects

What a battery connects to

A battery changes how your solar, grid, generators and chargers behave, so we design them together.

LFP battery racks, a battery management system (BMS), a power conversion system (PCS) and an energy management system (EMS) that decides when to charge.

  1. More: Solar & wind
  2. More: Grid & DISCOM
  3. More: Generator sets
  4. More: EV charging
  5. More: Site loads
  6. More: Monitoring & EMS
Battery energy storage

LFP battery racks, a battery management system (BMS), a power conversion system (PCS) and an energy management system (EMS) that decides when to charge.

  1. Solar & wind

    HYBRID PCS · TIME-SHIFT

    Store midday solar and use it after sunset instead of exporting it.

  2. Grid & DISCOM

    PEAK SHAVING · TOD TARIFFS

    Stay within contract demand and move use out of peak-tariff hours.

  3. Generator sets

    HYBRID CONTROL · FEWER STARTS

    The battery covers short outages and light loads, so the genset starts less often.

  4. EV charging

    DC FAST · 2W/3W · FLEET AC

    A battery lets fast chargers share a smaller grid connection.

  5. Site loads

    CRITICAL BACKUP · POWER QUALITY

    Where the system is designed to island, critical loads keep running through outages and dips.

  6. Monitoring & EMS

    ENERGY 107 · SOC · ALARMS

    Energy 107, our monitoring layer, tracks charge, temperature and alarms and runs the schedule.

Research

Why integration matters

An EPRI study of grid-scale battery failures found integration, assembly and construction to be the most common root cause.

72% of failures with a known system age happened during construction, commissioning or the first two years of operation.

Source: EPRI, Insights from EPRI's BESS Failure Incident Database: Analysis of Failure Root Cause (opens in a new tab) (May 2024).Based on incidents with enough public root-cause information.

What we do about it

  1. Engineer the interfaces. Protection, cooling, fire systems and controls are designed as one system.

  2. Test before handover. Every alarm, trip and fire-system interlock is function-tested.

  3. Watch the early years. Closer monitoring in the first two years.

How we integrate

How we work

Our project process

Six stages, each ending in a named document.

  1. Assess

    Site & data review

    Deliverable: Load & tariff report

  2. Design

    Design basis & safety layout

    Deliverable: Design basis report

  3. Build

    Installed system & records

    Deliverable: Installation records

  4. Commission

    Tested, inspected, handed over

    Deliverable: Handover dossier

  5. Operate & maintain

    Monitored and maintained

    Deliverable: Monthly performance report

  6. Repurpose & recycle

    Second life or recycling

    Deliverable: End-of-life plan
