COMMERCIAL AND INDUSTRIAL BATTERY STORAGE

AlphaESS STORION-LC-TB125
all-in-one liquid-cooled cabinet

STORION-LC-TB125 combines a 125 kW-class power conversion system with 261.2 kWh of lithium iron phosphate battery storage, energy management, battery management, liquid cooling and product-specific fire protection within a pre-assembled outdoor cabinet.

It is designed for commercial and industrial projects requiring a larger step in power and capacity, with connected control and the potential to scale through an approved multi-cabinet architecture.

A commercial system designed around deployment and control

Pre-assembled

Core components are integrated before delivery, reducing on-site equipment assembly.

Liquid-cooled

Precision thermal management supports consistent operating conditions across the battery system.

Connected

EMS functions and approved interfaces support scheduled operation, monitoring and integration.

Scalable

Develop a multi-cabinet architecture around the required power, capacity and operating strategy.

Why choose the LC-TB125?

Solar self-consumption

Store surplus on-site generation for use when demand is higher or solar output falls.

Peak management

Use scheduled charge and discharge to manage defined periods of high site demand.

Time-of-use optimisation

Shift energy use between tariff periods where the site, contract and operating strategy support it.

Operational resilience

Design selected backup loads around the available stored energy and approved switching architecture.

Microgrids

Coordinate storage with local generation, loads and, where required, generator support.

Flexibility services

Connect eligible systems to approved optimisation or flexibility services, subject to technical and commercial qualification.
INTEGRATED

Integrated before it reaches site

The cabinet brings together battery modules, PCS, BMS, EMS, liquid cooling and fire-response components. Factory integration can simplify deployment, but the project still requires design, foundations, lifting, electrical works, protection, communications, commissioning and an operating plan.
STORION LC TB125 cabinet interior
PCS
Converts power between the battery and the site's AC system.
BMS
Monitors battery conditions, balances cells and applies protective limits.
EMS
Controls charging, discharging and approved operating strategies.
Liquid Cooling
Monitors battery conditions, balances cells and applies protective limits.

Control storage around the way the site uses energy

STORION-LC-TB125 supports scheduled charging and discharging, solar self-consumption, demand control and generator-related strategies through its energy management system.

Modbus TCP and API connectivity can support approved third-party energy platforms, optimisation services and flexibility-market integrations. Available functions depend on the UK system configuration, metering, communications and selected service.

SAFETY

Layered protection and operating visibility

STORION-LC-TB125 uses lithium iron phosphate battery chemistry together with cell and system monitoring, liquid-cooled thermal management and product-specific fire-response provisions.

Current AlphaESS product information references smoke and temperature detection, aerosol response and sprinkler protection. The exact features and evidence should be confirmed against the approved UK product documentation before publication.

Together, these measures provide layered protection within the cabinet, supporting early detection, thermal management and product-specific fire response.

Combined with appropriate site design, professional commissioning and planned maintenance, these protections form part of a wider project-specific fire and operational safety strategy.

BACKUP

Backup is an engineered option

An optional static transfer switch cabinet can support compatible backup configurations, with the current datasheet referencing switching of up to 20 ms.

Actual continuity depends on the complete electrical architecture, supported loads, stored energy, system power limits, protection settings and commissioning. Backup must not be described as automatically supporting the entire site or providing uninterrupted power in every circumstance.

The datasheet notes that the STS cabinet is a separate outdoor cabinet, not part of the main TB125 enclosure.

FAQs
What size is the STORION LC TB125?

Each main cabinet provides 261.2 kWh of battery capacity with a 125 kW class power conversion system. The cabinet measures approximately 1,003 mm wide, 1,500 mm deep and 2,482 mm high, with a stated weight of approximately 3.3 tonnes.

Optional DC/DC and STS equipment uses separate outdoor cabinets. A complete project may use one or more TB125 units, subject to the approved system architecture and UK product limits.

Is the TB125 suitable for outdoor installation?
The cabinet is rated IP55. The proposed location must still be assessed for foundations, access, flooding, drainage, temperature, clearances, fire strategy, noise and future maintenance.
Can the TB125 provide backup power?

Compatible backup operation is available using an additional STS cabinet. The current datasheet references switching of up to 20 ms. Supported loads, available power, switching performance and expected backup duration must be designed and commissioned specifically for the site.

Can it connect to third-party energy platforms?
The system supports Modbus TCP and API connectivity. Any external energy platform, optimisation service or flexibility-market application must be confirmed as compatible and approved for the UK project.
How quickly can the TB125 be installed?
The pre-assembled cabinet can reduce on-site equipment integration. The overall programme will still depend on technical design, grid approval, planning, civil works, electrical installation, lifting, communications and commissioning.
Is the TB125 a utility-scale product?
The TB125 is positioned primarily as a commercial and industrial battery storage cabinet. Multiple cabinets may form part of a larger project, while dedicated ASTER container platforms serve the utility-scale part of the AlphaESS range.
How many TB125 cabinets can operate together?

Multi-cabinet operation is possible within an approved system architecture. The permitted number of units depends on the product revision, operating mode, control architecture and project requirements. AlphaESS UK will confirm the applicable limits during technical design.
