Product overview
PowerFac-5M combines twelve 418 kWh battery clusters in a containerized DC-side architecture, giving 5,016 kWh nominal battery energy. This is not a complete AC power or usable-energy specification: PCS selection, operating window, auxiliary consumption, and the point of measurement must be defined for the project.
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.
Liquid-cooled thermal management
Include cooling auxiliary consumption in the project energy balance and request operating limits for the site's ambient conditions.
Twelve 418 kWh battery clusters
Twelve clusters at 418 kWh each total 5,016 kWh nominal energy. Confirm the quoted configuration and its interfaces in controlled drawings.
Containerized DC-side architecture
Define PCS, transformer, switchgear, EMS/SCADA and commissioning responsibilities separately. The battery-container rating does not define a complete AC system.
Key specifications
| Parameter | Value | Condition or note |
|---|---|---|
| Nominal energy | 5,016 kWh | Battery-side nameplate energy; usable energy at the project connection point requires a separate specification. |
| Nominal DC voltage | 1331.2 V | Battery-side voltage, not an AC grid-connection voltage. |
| DC operating voltage | 1164.8–1497.6 V | Confirm compatibility with the proposed PCS DC input range. |
| Battery cluster energy | 418 kWh | Energy stated for each of the twelve battery clusters. |
| Battery cluster quantity | 12 | Twelve clusters × 418 kWh = 5,016 kWh nominal energy. |
| Charge/discharge rate | ≤0.5P | Notation reproduced from the product sheet; request its power basis and test conditions before deriving a kW rating or duration. |
| Thermal management | Liquid cooling | Include cooling auxiliary consumption in the project energy balance. |
| Enclosure rating | IP55 | Battery packs are stated as IP65; the liquid-cooling unit compartment is excluded from the container IP rating. |
| Operating temperature | −20 to 50 °C | The sheet does not provide a temperature-dependent power curve; request the proposed operating limits. |
| Dimensions (L × W × H) | 6058 × 2438 × 2896 mm | Allow separately for installation clearances and service access. |
| Approximate mass | 43 t | Confirm the final shipping configuration for transport, lifting, and foundation design. |
Applications to evaluate
Renewable generation and energy shifting
Validate the duty cycle, site, interfaces, and operating objective before confirming model suitability.

Validate the duty cycle, site, interfaces, and operating objective before confirming model suitability.
Review the application requirements
Selection, supply scope and engineering notes
- Define the target power, duration, dispatch profile, and usable-energy window from project data.
- Specify the battery container and the AC balance of system separately. Confirm whether PCS, transformer, switchgear, EMS/SCADA, communications, and protection are included in the quotation and who supplies each interface.
- Confirm civil works, installation, commissioning, and grid-interface responsibilities; a battery-container rating does not define a turnkey project scope.
- Request a controlled PowerFac-5M data sheet with a revision and issue date, plus the meaning of ≤0.5P, usable-energy conditions, and the proposed operating limits.
- Complete site-specific civil, access, fire, acoustic, environmental, and grid studies before procurement.
- Send interval generation/load data, installation country, ambient range, altitude, proposed PCS/AC architecture, quantity and schedule with the RFQ. Agree the configuration, warranty, maintenance responsibilities and acceptance criteria in the quotation.
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
Review the EMS interface, operating modes and commissioning responsibilities alongside the proposed battery and PCS supply scope.
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.
For transport planning, match the UN 38.3 test summary and shipping documents to the quoted battery model. Confirm the applicable requirements for the proposed shipment.

DC Container vs AC BESS
A battery container's MWh rating does not define a complete grid-connected AC energy storage system. Separate the DC battery boundary from PCS, transformer, switchgear, controls, civil works, installation, commissioning, and acceptance before comparing proposals.
Read guide →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.

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.

A useful BESS RFQ states the operating objective, site data, power, usable energy, duration, electrical interface, environment, safety requirements, scope split, documents, and acceptance criteria.

What buyers ask before specifying a battery system
Answers cover the information needed to confirm configuration, operating conditions, documentation, price, and delivery.
Does PowerFac-5M specify a 5 MW AC system?
No. PowerFac-5M specifies 5,016 kWh of nominal battery energy in a DC-side container, not a 5 MW AC output rating. The source sheet states a charge/discharge rate of ≤0.5P without defining its power basis. Confirm that definition, the PCS configuration, site conditions, and measurement point before specifying AC power or discharge duration.
Are PCS, transformer, EMS and commissioning included with PowerFac-5M?
The battery-container specification does not establish a turnkey supply scope. Ask for the quotation to identify who supplies the PCS, transformer, switchgear, EMS/SCADA, protection, communications, auxiliary supply, civil works, installation, and commissioning. Compare proposals using the same equipment and service boundaries.
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.
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.
Which certifications are available?
Certification scope varies by model and destination. Request the current certificate and test-report package for the exact quoted model.
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.
