Utility Scale ESS 5015 kWh Liquid Cooled DC Battery Container for Large Solar Storage

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

Large photovoltaic projects with constrained battery layouts

Use a compact battery block to plan energy storage beside a solar collector station. Stored solar energy can be dispatched after the production peak through the separately selected PCS. Container density supports layout planning, but does not replace a full fire, foundation, lifting and maintenance-access study.

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

Narrow cold plates and 314 Ah cells provide approximately 5 MWh in a 20 ft high-cube container. The stated container footprint is below 15 m²; the complete plant still needs service clearances, fire separation, PCS equipment and access roads.

Liquid cooling for thermal consistency

Water-and-glycol cooling is specified with a temperature difference of <2.5°C (battery cells). Narrow cold plates and active balancing support the compact architecture. Thermal performance contributes to consistent operation; it does not eliminate degradation or replace operating limits.

Layered electrical and fire protection

Pack, cluster, battery-bank and system-level fuse protection is described, together with cell-to-cluster insulation, pack/container sensing, gas and water suppression, active exhaust and explosion venting. Final equipment, water interfaces and fire strategy are confirmed with the manufacturing partner and site designers.

Maintainability and operating visibility

AI-based remaining-life and safety-risk prediction, active balancing and automatic cluster switching are described as maintenance-support features. 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. The source describes an AC-coupled configuration using 215 kW modular PCS units. This listing is for the DC battery container; PCS inclusion, topology and the 2500 kW configuration rating require separate project agreement.

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.
