3727 KWh Utility Scale Battery Energy Storage Systems Liquid Cooled For Grid

Equipment and Supply Scope

This listing covers the DC-side battery container, including LFP batteries, battery management, thermal management, DC distribution and the specified protection systems. It is not a complete AC-connected power station. PCS, plant EMS/PPC, transformers, switchgear and grid connection equipment are separate project items unless expressly included in the agreed supply scope.

YINTU is an energy storage solution provider. We work with manufacturing partners to select battery equipment and coordinate the interfaces required for each project.

Grid and Renewable Energy Applications

Grid support: maintain an energy reserve for dispatch

Pair the DC battery block with a suitable bidirectional PCS and plant controller for scheduled charging, peak-period discharge and contracted reserve duties. Reserve energy and state-of-charge limits must be assigned before committing the same battery capacity to other services.

Renewable output smoothing and dispatch control

A coordinated PCS and plant EMS can charge or discharge the battery to moderate short-term variations in photovoltaic or wind output and follow an export schedule. The achievable ramp rate and response depend on converter capability, communications, available state of charge and the grid operator’s requirements.

Frequency regulation and operating reserves

The battery supplies or absorbs active energy when the selected PCS and controller respond to a regulation signal. Reserve availability must respect battery voltage, temperature, charge/discharge limits and state of charge. Frequency response is a complete-system function, not a standalone guarantee from the battery enclosure.

Peak management at a grid connection

Discharging during defined high-load intervals can reduce the peak power requested from a connection or support a constrained node. Suitability depends on the local load profile, connection limit and required duration. Any infrastructure-deferral or revenue case needs a project study; the battery rating alone does not establish the result.

System Features and Project Value

A defined energy block for plant design

Dedicated cluster sub-controllers manage charge and discharge while liquid cooling limits the stated temperature difference to 3°C or less. This supports coordinated battery operation within a plant dispatch strategy.

Liquid cooling for thermal consistency

Water-and-glycol cooling is specified with a temperature difference of ≤3°C. Online leak detection and cluster-level control support monitoring of the cooling and battery systems. Thermal performance contributes to consistent operation; it does not eliminate degradation or replace operating limits.

Layered electrical and fire protection

The source describes online insulation monitoring, four-level circuit-breaker protection and pack-level combustible-gas detection linked to BMS/EMS. Targeted suppression and the selected fire system support fault response. Final equipment, water interfaces and fire strategy are confirmed with the manufacturing partner and site designers.

Maintainability and operating visibility

Each cluster has a dedicated sub-controller for charge/discharge management and balancing. Cloud monitoring is described in the source; connectivity and service scope are confirmed per project. The non-walk-in enclosure allows external maintenance. Monitoring supports inspection and planning but is not a guarantee of uninterrupted availability.

How the System Fits Your Site

In the illustrated AC-coupled example, the battery DC output connects to a compatible bidirectional PCS, then through the project transformer and switchgear to the grid. A photovoltaic plant connects through its own inverter and interface equipment to the AC collector. Plant EMS/PPC coordinates dispatch and exchanges status with the BMS. This battery container does not connect directly to PV strings or the AC grid. Alternative architectures require an approved project design.

Interfaces and Project Scope

Auxiliary AC supply ratings describe internal service power, not AC export capability. “CP” and “P2” are source designations retained without reinterpretation. Nameplate battery energy is not guaranteed usable AC energy. Standards are source references; confirm certificates and test-report scope for the supplied configuration.

From Project Requirements to a Storage Plant

1. Define power, energy and dispatch

Use generation and grid-dispatch profiles to define AC power, usable energy, delivery duration and reserve commitments. Evaluate auxiliary demand, conversion losses, temperature derating and the agreed end-of-life capacity target.

2. Match equipment and site design

YINTU coordinates battery and PCS interface reviews with manufacturing partners. Check the full DC voltage window, communications, grid requirements, foundations, lifting access, corrosion conditions and maintenance clearances.

3. Confirm the project scope

Confirm the battery supply boundary, external PCS, plant EMS/PPC, transformer, switchgear, protection, auxiliary power, civil works, fire design and commissioning responsibilities. Grid connection and local approvals are project-specific.

Frequently Asked Questions

Does this product include a grid-connected inverter?

The published scope is the DC battery container. A compatible PCS and the required AC/MV interface are specified separately. The auxiliary AC supply does not make the container a standalone grid-connected system.

Can solar panels connect directly to the battery container?

No direct PV-string interface is offered in this listing. Solar integration requires the appropriate PV inverter or DC conversion architecture, protection and plant controls. The illustrated scheme is one possible AC-coupled arrangement.

How many containers and how much PCS power are needed?

Start with the required AC MW, usable MWh, dispatch duration and end-of-life target. Account for the usable SOC window, conversion losses, auxiliary demand, temperature derating and reserve commitments. Select the converter against the entire battery voltage window and the agreed charge/discharge limits.

Can it provide backup, grid-forming or black-start operation?

These functions require a specifically engineered complete system, including suitable PCS controls, auxiliary-power arrangements, protection and an approved operating sequence. They are not standalone capabilities guaranteed by this DC battery container.

Is the listed cycle life a warranty?

No. The ≥6000-cycle figure applies under the stated test conditions, depth of discharge and end-of-life threshold. Warranty terms and expected degradation for the actual operating profile require a separate agreement.

Parameters are based on the supplied model datasheet and remain subject to final technical confirmation. Illustrations show application concepts, not completed YINTU projects. Listed standards require configuration-specific documentation; cycle life and design life are not warranty commitments.
