5.016 MWh Utility Scale Energy Storage Systems Liquid Cooled Utility ESS IP54

Product Overview

The 5.016 MWh configuration combines 314 Ah LFP cells with a stated 2.5 MW power rating and a 1331.2 V rated DC bus. It provides the largest energy block in these three configurations for developers assessing large solar-plus-storage plants and scheduled grid dispatch. Its 45,000 kg source weight makes transport, lifting and foundation planning an early design consideration.

YINTU is an energy storage solution provider. We work with capable manufacturing partners to match battery equipment, clarify technical interfaces and coordinate a defined supply proposal for developers, EPCs and project owners.

Key Features

Modular container architecture

Large battery modules and an integrated architecture support coordinated installation, operation and maintenance. A defined block helps EPC teams plan repeated equipment interfaces across a larger plant; final dimensions, equipment arrangement and service access follow the approved drawing.

Liquid-cooled battery operation

Liquid cooling provides the thermal-management approach for the selected LFP configuration. The project review should establish ambient operating limits, cooling auxiliaries, maintenance access and operating setpoints. The supplied sheet does not state a universal temperature-uniformity or cycle-life guarantee.

Battery consistency and layered protection

The source describes multiple balancing measures and integrated gas and water fire-suppression devices. These features form part of the equipment protection strategy. Site fire design, detection interfaces, water connections and emergency procedures are coordinated for the installation.

Monitoring for plant operations

Multidimensional battery analysis supports fault location, while real-time cloud monitoring provides operating visibility. LAN, CAN and RS485 interfaces with Modbus TCP support integration planning. Remote access, communications mapping, cloud service and cybersecurity requirements are agreed for the project.

Enclosure durability

C4H enclosure protection and an enclosure service-life claim exceeding 15 years are listed in the source. These describe the enclosure and must not be treated as a battery capacity warranty. Confirm site conditions, protective-coating documentation and maintenance requirements for the destination.

Applications and Project Value

Large solar-plus-storage developments

Plan multi-MWh storage alongside a solar collector system to extend energy delivery beyond the production peak. The 5.016 MWh block can support energy-block sizing, while usable AC delivery is calculated from the agreed SOC window, reserve, efficiency and auxiliary consumption. The final plant layout must include converter equipment, access and project-specific safety clearances.

Grid-connected energy shifting

Charge and discharge under an approved operating schedule to align stored energy with grid demand. The project value comes from flexibility in when energy is delivered. Market rules, tariff structures, interconnection limits and degradation assumptions determine the business case; equipment ratings alone do not establish revenue.

Grid regulation and operating reserve

With a suitable PCS, plant controller and approved connection scheme, battery storage can be assessed for active-power regulation and reserve duties. Maintain sufficient state-of-charge and power headroom for the contracted service. Response performance and service eligibility belong to the complete system and require project validation.

Large industrial and renewable campuses

Combine onsite generation and storage to shift energy toward production periods and manage selected demand peaks. Coordinate the storage schedule with plant operations, connection capacity and any reserved energy. Backup or island operation requires a separately verified control and protection design.

Plant Integration Concept

In an AC-coupled concept, the battery DC system exchanges energy with a bidirectional PCS. The AC side connects through project-selected transformer, switchgear, metering and protection equipment to the grid or site bus. A solar plant connects through its PV inverter. Plant EMS/PPC coordinates dispatch while exchanging battery status and limits with the BMS.

Battery and Electrical Ratings

Enclosure, Thermal Management and Communication

The 1500 V platform description is a voltage class, not the nominal DC voltage. The 93% DC-side figure and >89% system-efficiency figure have different source descriptions and are retained separately; no AC round-trip efficiency is inferred. Rated energy is not guaranteed usable AC energy. The source lists 690 V AC but does not define the PCS location or a complete bill of supply. Confirm PCS inclusion, transformer, switchgear, plant EMS/PPC and site interfaces in the technical agreement.

Standards and Project Documentation

Standards listed in the supplied series datasheet: IEC/EN 62477, NFPA 855, IEC/EN 62619, IEC/EN 60730, IEC/EN 63056, UL 1973 and UL 9540A. Confirm model-specific certificates, test reports and their scope. These references do not replace the applicable site design, utility interconnection process or local approvals.

Configuration and Supply Planning

Prioritize the total plant energy target, transport route, lifting capacity and foundation design. Review the upper DC operating voltage of 1497.6 V against the selected converter and protection equipment.

Share the target AC MW and usable MWh, generation or load profile, grid connection voltage, operating schedule, climate and available site layout. YINTU coordinates equipment selection and technical clarification with manufacturing partners. The proposal defines included batteries, cooling, protection, controls, conversion equipment and project accessories. Installation, commissioning, transport, civil works and grid connection services are included only where agreed.

Frequently Asked Questions

Is PCS equipment included?

The sheet specifies rated system power and 690 V AC but does not provide a complete equipment list or PCS arrangement. YINTU will confirm the battery, PCS, controls, transformer and switchgear boundaries in the project proposal. Do not treat the illustration as proof of included conversion equipment.

Can PV strings connect directly?

No direct PV-string or MPPT input is specified. Solar integration requires a project-selected PV inverter or another approved conversion architecture, protection and coordinated controls. The diagram shows an AC-coupled concept.

How long can the system discharge?

Actual duration depends on the load or dispatch power, usable SOC window, reserve requirements, conversion and auxiliary losses, operating temperature and end-of-life target. Nominal MWh divided by MW is a planning ratio, not a guaranteed delivered duration.

Does the product provide grid forming or black start?

These functions are not specified in the supplied datasheet. They require suitable conversion equipment, control functions, auxiliary-power arrangements and an approved operating sequence. Confirm them as explicit project requirements.

Are all listed standards certified?

The datasheet lists standards, but a listing does not establish certification of every supplied configuration. Request model-specific certificates and test reports, including their versions, applicable equipment and test scope.
