Energy Storage Containers
Delivering two cooling platforms within one project‑tailored system, our energy storage containers let you evaluate air‑cooled and liquid‑cooled platforms against energy duty, site conditions and integration scope.
Straightforward thermal management. Flexible project scope.
2.0–5.0 MWh · primarily 40 ft
A configurable platform for projects that prioritize accessible maintenance and conventional industrial cooling.
View configuration labels
Higher energy density. More controlled cell temperatures.
2.5–6.25 MWh · 20 ft
A compact platform for projects where energy density, temperature uniformity and frequent cycling shape the design.

The right platform depends on duty, space, environment and maintenance—not capacity alone.
Air-cooled
- •Proven, straightforward thermal design
- •Flexible for diverse site conditions
- •Simpler maintenance and integration path
Liquid-cooled
- •Higher energy density in a compact footprint
- •More controlled cell temperatures
- •Better fit for frequent cycling priorities

FAQ
Frequently asked questions
A: Air-cooled systems use conditioned or forced air to manage battery temperature. Liquid-cooled systems circulate coolant through a dedicated thermal circuit, supporting more uniform temperature control and higher packaging density. Final suitability depends on duty cycle, climate, footprint and maintenance requirements.
A: Frequent cycling increases thermal-management importance. Liquid cooling may offer advantages where temperature uniformity and higher utilization are priorities, but the final choice must be checked against the cell, duty profile and operating environment.
A: No. Container length alone does not determine energy capacity. Cell format, rack arrangement, cooling architecture, service clearances and system boundary all affect usable capacity.
A: PCS and EMS appear in some reviewed integrated configurations, while transformer, switchgear and site controller scope varies. The proposal and scope sheet must explicitly state what is included and what remains project-side.
A: Start from required power, usable energy and discharge duration. Grid service, peak shaving, backup and renewable integration can produce different power-to-energy ratios even at the same MWh capacity.
A: They must not be assumed identical. Certifications and standards are tied to the exact model, component set, market and current revision. Request the evidence package for the selected configuration.
A: Provide the load profile, required power and duration, grid interface, ambient and site conditions, footprint and access limits, required equipment scope, delivery destination and compliance requirements.
