125 KW / 265 KWh All In One Hybrid ESS Energy Storage System For Commercial

The YT-Hybrid ESS-125kW-265kWh combines a 125 kW hybrid inverter, a 265 kWh battery system, thermal management, fire protection and local EMS / SCADA in a cabinet with an approximately 2.2 m² equipment footprint. With up to 180 kW of PV input and a choice of 10- or 6-MPPT configurations, it is designed for commercial solar self-consumption, demand management and engineered backup or microgrid applications.

YINTU is an energy storage solution provider. We work with manufacturing partners to match equipment, configuration and project support to the site requirements of EPC contractors, installers and commercial operators.

Why Choose This Hybrid ESS?

• Integrated solar and storage: The hybrid inverter couples PV and the battery with AC sources and site loads, helping simplify equipment coordination in a new solar-plus-storage project.
• Flexible PV string design: Select 10 MPPTs with two inputs each, or six MPPTs with three inputs each. Match module strings, current limits and roof orientations to the chosen configuration.
• Compact cabinet integration: Battery PACKs, high-voltage control, inverter, EMS and auxiliaries are integrated. Installation planning must allow additional maintenance, ventilation and safety clearances.
• Coordinated operation: BMS / EMS control, local monitoring and cloud connectivity support charge/discharge scheduling and operational oversight.
• Thermal and protective functions: Smart air-conditioning and air cooling manage cabinet temperature. Smoke, temperature and hydrogen detection work with cabinet-level aerosol suppression.
• Room for project expansion: The datasheet lists a 125-500 kW parallel system power range, subject to the approved system configuration and electrical design.

Commercial and Industrial Application Scenarios

Factories and Workshops: Manage Short Demand Peaks

Production equipment and auxiliary loads can create short periods of high grid demand. An EMS strategy can schedule battery discharge against a site demand target and recharge when the load or tariff conditions are more favorable. Selection should use interval load data, the utility tariff and the duration of peaks; financial returns depend on those site conditions.

Warehouses, Retail and Business Parks: Use More Rooftop Solar

Sites with daytime PV surplus and later electricity demand can store part of that surplus for subsequent use. The 180 kW maximum PV input and alternative MPPT arrangements provide options for designing a compatible solar array. Existing PV inverter compatibility, export limits and metering must be reviewed when planning a retrofit.

Farms and Remote Commercial Sites: Coordinate Multiple Sources

For commercial farms, rural workshops and remote facilities, the hybrid architecture can coordinate solar, storage and an engineered generator or utility connection. Define irrigation, refrigeration and other essential loads before sizing the solution. Motor starting, generator interface requirements and source switching need project-specific verification.

Commercial Microgrids and Selected Backup Loads

The datasheet includes off-grid operation and black-start support for the engineered configuration. A project can allocate battery reserve to selected loads while maintaining a separate schedule for normal energy management. Transfer time is not specified, so uninterrupted or zero-transfer operation is not assumed. Backup duration depends on usable energy, load, state of charge, reserve settings and losses.

Remote Dispatch and VPP Projects

Local / cloud monitoring and EMS scheduling provide a basis for coordinated dispatch. Participation in a virtual power plant requires the agreed aggregator interface, communication services, market rules and local grid approval; it is defined as part of the project scope.

How the Hybrid System Works

PV feeds the hybrid inverter through the selected MPPT arrangement. The inverter manages energy exchange with the battery and supplies AC site loads. Utility or generator interfaces follow the approved design, while BMS and EMS coordinate operating limits, charging, discharging and protection. The diagram is a functional overview, not an installation wiring drawing.

PV Input and MPPT Selection

Select one MPPT configuration for the final order. The two options are alternatives, not cumulative ratings.

Battery and Thermal Management

Cycle-life figures are specified test values and do not establish a warranty period or guaranteed field lifetime.

Installation, Environment and Communication

Integrated Equipment and YINTU Project Support

The listed configuration includes 12 battery PACKs of approximately 22 kWh each, one battery cabinet and high-voltage box, one 125 kW hybrid PV-storage inverter, aerosol fire protection, smart air-conditioning and fans, local EMS / SCADA with cloud connectivity, and auxiliary distribution, cables and accessories. PACK values are rounded; the system-level rated energy is 265 kWh.

YINTU coordinates product selection with manufacturing partners, engineering documentation, configuration review, China-side quality and delivery arrangements, and agreed commissioning and after-sales support. Installation, grid connection, permitting and on-site responsibilities are defined with the local project team. Certificates, warranty, delivery schedule and the final bill of materials are confirmed in the project proposal.

Frequently Asked Questions

Can this cabinet connect directly to PV?

Yes. The integrated hybrid inverter provides PV input up to 180 kW, with the specified PV voltage limits and either the 10- or 6-MPPT arrangement. PV string design must suit the selected option.

How much space does the cabinet need?

The cabinet measures 1200 × 1860 × 2200 mm (W × D × H), with an equipment footprint of approximately 2.2 m². Provide additional space for access, maintenance, ventilation and the clearances required by the approved installation design.

Can it provide backup or run off-grid?

Off-grid and black-start support are listed. The final backup loads, switchgear, transfer performance, generator coordination and overload limits require engineering confirmation for the selected configuration.

What information is needed for a quotation?

Provide the project location, grid voltage and frequency, interval load profile, electricity tariff, existing or planned PV capacity, required backup loads and duration, generator details if applicable, and installation conditions. YINTU can then propose a suitable configuration and define the supply and service scope.
