Product overview
PowerFac-522 is designed for larger behind-the-meter projects that need 522 kWh in a single outdoor cabinet. Pro and Max configurations differ in system details; final option, fire design, controls, and operating strategy must be confirmed in the proposal.
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
Industrial and commercial energy management
Validate the duty cycle, site, interfaces, and operating objective before confirming model suitability.
Renewable integration and peak management
Validate the duty cycle, site, interfaces, and operating objective before confirming model suitability.
Data centers and site resilience
Validate the duty cycle, site, interfaces, and operating objective before confirming model suitability.
Microgrid and mobile-power support
Validate the duty cycle, site, interfaces, and operating objective before confirming model suitability.
Selection, supply scope and engineering notes
- Select the 125 kW or 250 kW configuration from the required power-to-energy ratio and site duty cycle.
- Confirm whether the Pro or Max architecture is proposed and document the BMS balancing and fire-system scope.
- Validate usable energy, PCS, EMS, grid interface, ambient conditions, clearance, foundation, and service access for the site.
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.
Read guide →BESS Safety Review
A BESS safety review should connect cell and module behavior to electrical protection, BMS controls, thermal management, enclosure, fire strategy, emergency response, site layout, installation, and operating procedures.
Read guide →Frequently asked questions
What buyers ask before specifying a battery system
Answers cover the information needed to confirm configuration, operating conditions, documentation, price, and delivery.
What information is needed to size a battery energy storage system?
Provide the load profile, target power and energy duration, grid or generator constraints, installation environment, operating temperature range, and the functions the system must perform. A single capacity figure is not enough for responsible system selection.
When should I consider air-cooled or liquid-cooled energy storage?
Cooling selection depends on system size, heat density, ambient conditions, enclosure layout, service access, and the project performance target. Compare the complete thermal design rather than choosing from capacity alone.
Is nameplate energy the same as usable energy?
Not necessarily. Usable energy depends on the permitted state-of-charge window, operating conditions, conversion losses, control strategy, and project limits. Ask for both nominal and usable values in the final proposal.
What safety information should a BESS proposal include?
A project proposal should identify the cell chemistry, electrical protection, BMS architecture, thermal management, enclosure rating, fire strategy, emergency isolation, monitoring, installation limits, and the standards required by the destination project.
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.
