Shenzhen, China – July 2022 — Lingtech Group, a global energy storage system (ESS) integrator and turnkey manufacturer, has introduced its new 261 kWh / 125 kW Battery Energy Storage System (BESS).
The system is engineered for medium-scale commercial and industrial facilities, offering fully integrated DC-AC conversion, liquid cooling, fire safety, alarm, and EMS functions within a single modular platform.
The Lingtech 261 kWh / 125 kW BESS bridges the gap between small-scale and utility-grade energy storage solutions.
It provides customers with a plug-and-play turnkey system, factory-assembled and tested for fast global deployment.
System highlights include:
🔋 Rated Capacity: 261 kWh
⚡ Rated Power: 125 kW (bidirectional inverter)
🔧 Battery Type: LFP (LiFePO₄) high-safety chemistry
🌡️ Thermal Management: Advanced liquid-cooling system for uniform temperature distribution
🧯 Safety Systems: Automatic fire suppression and alarm integration meeting IEC and UL standards
🧠 Energy Management System (EMS): Built-in controller for load management, peak shaving, and grid interaction
🔌 Installation: Pre-configured container with AC and DC interfaces, ready for commissioning on site
The system is suitable for daily-cycling operations, supporting applications such as factory load shifting, commercial building demand control, and solar self-consumption optimization.

For typical commercial users consuming 800 – 1,200 kWh per day, the Lingtech 261 kWh / 125 kW system can reduce energy bills by up to 50 % through peak-shaving and valley-filling operation modes.
In renewable hybrid configurations, the system can store daytime solar power for evening consumption, enhancing self-consumption rates and reducing grid dependence.
The compact footprint and high integration make it ideal for:
Manufacturing plants and industrial parks
Logistics warehouses and data centers
Commercial buildings and EV charging stations
Remote microgrids and renewable energy sites
Unlike single-component battery suppliers, Lingtech Group serves as a complete energy storage system integrator, manufacturing and assembling:
DC battery systems
AC inverters and switchgear
Fire and safety subsystems
Lighting and alarm modules
EMS software platforms
Pre-fabricated containers and electrical wiring
Lingtech’s engineers also provide on-site installation, commissioning, and long-term service support, ensuring global customers receive a true turnkey solution ready to operate immediately upon delivery.
The 261 kWh / 125 kW BESS sits between Lingtech’s 215 kWh / 100 kW and 430 kWh / 200 kW models, forming part of a broader range spanning from 105 kWh / 50 kW to 100 MWh / 50 MW.
All models share a standardized design philosophy: modular, customizable, and ready-to-install, enabling rapid project execution for both EPC contractors and renewable developers.
The new Lingtech 261 kWh / 125 kW Battery Storage System demonstrates the company’s commitment to providing efficient, safe, and fully integrated energy storage solutions for global commercial and industrial clients.
With its turnkey design, liquid-cooling technology, and intelligent EMS control, Lingtech continues to strengthen its position as a rising Chinese leader in the global BESS market.
