125 kW / 261 kWh Liquid-Cooled C&I Storage Cabinet - CE Version
A 125 kW AC storage cabinet with 261.248 kWh of nominal LFP battery energy for commercial and industrial energy management. This CE-version configuration is designed for projects that need a compact outdoor storage unit, liquid-cooled batteries and coordinated on-grid or off-grid operation.
Equipment Overview
The cabinet integrates five battery packs, PCS, BMS, EMS, liquid cooling and a control box. Its source configuration is YTDS5T261L-P0125S (Smart261L-CE). Solar integration in the concept shown below uses an external PV inverter on the AC bus; a direct PV DC input is not specified for this cabinet.
YINTU is an energy storage solution provider. We work with capable manufacturing partners to match equipment, system configuration and project services to each customer's commercial or industrial site.
Commercial & Industrial Application Scenarios
Factories and industrial parks
Use scheduled charging and discharging to manage short demand peaks from production equipment and common services. YINTU starts with interval demand data, transformer limits and tariff periods to define an operating schedule and battery reserve. Savings depend on the site's actual load and tariff structure.
Commercial rooftop PV retrofits
Add storage alongside an existing PV inverter to move available daytime solar energy toward later consumption. The project design coordinates the PV inverter, metering and EMS, including any export limits. This AC-coupled arrangement is suitable for assessment where a working rooftop PV system is already installed.
Warehouses and cold-chain facilities
Plan storage around refrigeration cycles, loading equipment, lighting and other essential services. Separating priority loads helps set a realistic backup objective. Motor-starting demand and the required autonomy must be checked before confirming an off-grid configuration.
EV charging and logistics depots
Use the cabinet as part of a demand-management scheme when vehicle charging overlaps with site production or building demand. Charging schedules, connection capacity and available battery energy determine how much peak buffering is practical.
Staged storage expansion
The datasheet lists parallel expansion up to 2.5 MW. A multi-cabinet project requires a coordinated electrical layout, controls, protection and grid-interface review. VPP participation is assessed only where local rules, communications and commercial arrangements permit.
System Features and Project Value
Integrated cabinet architecture
Five LFP packs and the power-conversion, battery-management and energy-management functions are packaged in one cabinet, helping simplify equipment coordination for a site-specific solution.
Liquid cooling and outdoor protection
The source specifies intelligent battery liquid cooling, C4 corrosion protection, IP54 for the cabinet and IP55 for the battery compartment. These are distinct protection ratings and must be matched to the installation environment.
Efficient conversion and monitoring
The datasheet reports up to 99% SiC PCS conversion efficiency. This is a PCS value, not whole-system round-trip efficiency. Local operation, cloud/OTA capabilities and remote diagnostics are listed; project communications and access arrangements are confirmed separately.
Layered safety provisions
The datasheet describes dual monitoring, fault isolation and multiple venting/fire-protection measures. The final fire-protection arrangement, site emergency response and installation clearances are established in the approved equipment and project documents.
How the System Fits Your Site
The conceptual AC-coupled arrangement connects the storage cabinet, utility grid, external PV inverter and commercial loads through the site AC bus. The EMS coordinates the storage operating schedule. Backup or island operation requires suitable isolation, switching and protection; the drawing does not imply that an existing site is automatically ready for off-grid operation.

From Site Requirements to a Storage Solution
1. Define the operating objective
Identify whether the priority is peak management, solar self-consumption, backup or microgrid operation. Use the actual load profile and generation resources to set the power, energy and operating reserve.
2. Match equipment and interfaces
YINTU coordinates equipment selection and technical clarification with the manufacturing partner, including voltage, controls, environment, expansion and optional functions.
3. Confirm delivery and service scope
The project quotation defines the cabinet configuration, external switchgear, protection and metering, PV equipment, generator interface, transport, commissioning support and after-sales responsibilities. External equipment and on-site works are included only when expressly specified. Warranty, lead time and commercial terms are confirmed in the agreed quotation.
Frequently Asked Questions
Can this cabinet take PV strings directly?
A direct PV DC input is not specified in this datasheet. The solution shown uses an external PV inverter connected to the site AC bus. PV-inverter compatibility and EMS coordination are reviewed for each project.
Does 261.248 kWh guarantee a fixed backup duration?
No. Runtime depends on actual load, allowed state-of-charge range, reserve settings, conversion losses, temperature and equipment limits. Power and energy must both be checked against the required duty.
Is the CE version already approved for every European site?
The datasheet lists standards and grid-code references. The applicable certificate scope, firmware, network settings and local utility requirements must be checked for the exact project and delivered configuration.
Is YINTU the cabinet manufacturer?
YINTU provides solution selection, project coordination and supply support through manufacturing partners. The final quotation identifies the equipment and service responsibilities.
