5117 KWh Utility Scale Energy Storage Systems 30 Ft Air Cooled LFP Battery

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 energy shifting: align stored energy with peak demand

Charge under an approved dispatch schedule and discharge through an external PCS during the selected peak period. The battery provides the energy reservoir; the PCS defines the AC conversion capability. Usable energy, reserve margins and conversion losses determine the actual delivery duration.

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

The 30 ft enclosure concentrates more than 5 MWh of nominal battery energy in one container. Its approximately 52 t weight and service access requirements should be addressed early in transport, crane and foundation planning.

Controlled airflow across battery packs

Tree-inspired airflow channels and pack-level fan-speed control are described in the datasheet, with system temperature difference at or below 5°C. Coordinated cooling helps manage thermal conditions during the planned duty cycle. Ambient temperature and cooling auxiliary consumption must be included in the plant energy model.

Layered monitoring and protection

The three-level BMS works with DC collection, grounding and protection systems. Pack-targeted suppression, combustible-gas detection, smoke prevention and explosion venting are described alongside 5VA insulation materials. Final fire-system selection and site fire design require configuration-specific review.

Service life planned around real duty

The source states a 20-year design life and up to two charges and two discharges per day. These are design references, not a warranty or a promise of constant lifetime capacity. Dispatch depth, ambient conditions, maintenance and end-of-life capacity targets need to be agreed for the project.

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” is the source rate notation 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.
