    Battery energy storage systems

    C&I storage cabinets and larger modular systems for peak shaving, backup and solar storage.

    Systems

    From 100 kWh cabinets to multi-MWh containers.

    Rack-based cabinets for commercial sites, containerized units for industrial and utility deployments. Fire-rated enclosures, integrated HVAC, and safety systems engineered for the site.

    Use cases

    Peak shaving, backup, renewable integration.

    Reduce demand charges, ride through outages, and firm up PV or wind on the same site. Dispatch strategy tuned to the tariff, the load, and the generation profile.

    Frequently asked

    What size BESS does a site need?
    Two numbers decide it: power in kilowatts, set by the largest peak to be shaved or the load to be carried, and energy in kilowatt hours, set by how long that must last. Efficiency losses and end of life capacity are added on top, usually 10 to 20 percent.
    How long does a BESS last?
    Lithium iron phosphate cells are typically warranted for 6000 cycles or 10 to 15 years to 70 or 80 percent of original capacity. Inverters and cooling are shorter lived and are treated as serviceable items in the maintenance plan.
    Can a BESS replace a generator?
    For short outages, yes, and without transfer delay or fuel. For outages measured in many hours or days, a generator still carries the energy, while the BESS covers the transition and reduces generator run time.
