Price on application
Utility-scale systems are engineered, configured and priced per project — the final quotation depends on the number of containers, medium-voltage interface, transformer and switchgear, civil and grid-connection works, and the site's duty cycle. Tell us your power, energy and application targets and our engineers will scope and price a complete solution.
Why developers choose the integrated container.
All-in-one 20-ft container
Battery, modular PCS, cooling and fire safety integrated in one shippable 20-foot unit — the fastest to site and commission.
Modular PCS architecture
A modular power-conversion system eliminates circulating current between battery racks, improving reliability and serviceability.
More energy, lower LCOE
Lifetime discharge increased by 6–8% and LCOE reduced 3–5% versus conventional designs — better economics over 20 years.
Higher energy density
~18% higher energy density and a 30% smaller footprint — more MWh on the same pad.
Liquid-cooled & safe
Liquid cooling with flammable-gas detection, active ventilation, optional pack-level suppression and water fire-fighting.
Lower O&M
Integrated design and smart monitoring cut operations-and-maintenance time by around 20%.
