Battery Energy Storage Systems (BESS)

Power costs are rising, grid constraints are tightening, and uptime expectations have never been higher. Our Battery Energy Storage Systems (BESS) give you a smarter way to store and deploy energy on demand—helping you cut peak charges, increase resilience, and unlock more value from on-site generation like solar PV and standby generators.

We supply a growing range of BESS units, including Cummins solutions, alongside carefully selected systems built for commercial and industrial sites. From compact packages to larger containerised systems, we’ll help you size, supply and support the right battery storage for your application—whether you need fast response power, longer duration runtime, or a scalable platform that grows with your site.

What BESS can do for your business


Reduce energy costs

  • Peak shaving and load shifting to lower demand charges
  • Time-of-use optimisation (charge off-peak, discharge at peak)
  • Improve power factor and smooth site load profiles (system dependent)

Increase resilience

  • Instant response for critical loads during supply disturbances
  • Seamless support for backup strategies when paired with a generator and/or UPS
  • Greater continuity for sites where the grid is limited or unreliable

Support decarbonisation

  • Store excess solar PV for evening use
  • Reduce generator run hours and fuel consumption in hybrid systems
  • Enable smarter energy use without compromising performance

Unlock flexibility

  • Fast, controllable power for high inrush loads and dynamic site demand
  • Scalable capacity—add kW/kWh as requirements evolve

FAQs about our Battery Energy Storage Solutions (BESS)?

What are the typical applications for your range of BESS?

  • Manufacturing and industrial facilities
  • Data centres, comms and critical infrastructure
  • Construction, events and temporary power setups
  • Warehousing and logistics hubs
  • Renewables + storage (PV self-consumption)
  • Microgrids and grid-constrained sites

How do I choose the right size Battery Energy Storage System (BESS)?

Two key numbers matter:

  • kW (power): how much load the BESS can supply at once
  • kWh (energy): how long it can supply that load

A quick rule of thumb: runtime (hours) ≈ kWh ÷ kW (then allow for efficiency and any reserve/SOC limits).

Can the BESS be used for peak shaving?

Yes—peak shaving is a core use case called out across the product summaries and overviews.

Can BESS work with generators / microgrids?

Yes—these systems are described for microgrids, and include EMS/communications intended for integration with wider site power systems (and, on at least some listings, explicitly mention integration with gensets/DER)

Can these BESS run on-grid and off-grid?

Yes—multiple models are described as supporting on-grid and off-grid operating modes.
