Product overview
These cabinets supply a high-voltage DC battery connection. A project needs a compatible PCS, controls and AC-side protection to serve grid or building loads. Compare the battery current, enclosure dimensions and floor loading for the two sizes.
Configuration note: nameplate values help define the starting point. Final usable energy, interfaces, operating limits, document scope, and commercial terms are confirmed for the specific project.

Applications to evaluate
DC battery integration with a separate PCS
Validate the duty cycle, site, interfaces, and operating objective before confirming model suitability.
Selection, supply scope and engineering notes
- Specify PCS DC voltage and current limits, AC power, control protocol and protection coordination.
- Plan an indoor location with adequate ventilation, service access and floor load capacity.
- State the required usable energy and duty cycle alongside nominal battery capacity.
Confirm the project responsibility matrix
The product rating does not define a turnkey project scope. The quotation should identify who supplies, integrates, installs, commissions, and accepts each applicable item.
- Battery system, BMS, thermal management, enclosure, internal protection, and communications
- PCS, EMS or SCADA, transformer, switchgear, metering, external protection, and grid interface
- Fire strategy, foundations, lifting, cable routing, installation, testing, and commissioning
- Documentation, training, spare parts, warranty conditions, maintenance, and acceptance records
Technical documents
Use the public page and any available procurement brief for initial comparison. Request the applicable controlled data sheet, drawings, test or certificate evidence, and commercial documents for the exact quoted model and destination.
Guides for your technical review
C&I BESS Sizing Guide
A defensible C&I battery energy storage system size comes from interval load data, a ranked operating objective, power constraints and usable energy at a stated measurement point. Start with the duty the site needs, then evaluate the cabinet or container configuration against it.
Read guide →Air vs Liquid Cooling
Air and liquid cooling are system-level choices. Compare heat density, temperature uniformity, ambient conditions, parasitic demand, acoustic limits, maintenance, fault response, and site layout—not capacity alone.

What buyers ask before specifying a battery system
Answers cover the information needed to confirm configuration, operating conditions, documentation, price, and delivery.
Why are prices not published on the product pages?
The listed products are project-configured B2B systems or battery series. Pricing depends on configuration, quantity, accessories, packaging, destination, and commercial terms, so quotations are prepared against a defined project scope.
What is the production and delivery lead time?
Lead time is confirmed only after the configuration, quantity, compliance documents, packaging, and destination are known.
