YAHUA Outdoor Cabinet Series Y241 / Y261
Commercial & Industrial ESS Cabinets
Integrated outdoor LiFePO4 energy-storage cabinets in 50 kW / 241 kWh air-cooled and 125 kW / 261 kWh liquid-cooled configurations.
Product overview
Built around the application.
The YAHUA Outdoor Cabinet Series combines long-life LiFePO4 batteries, intelligent battery management, power conversion, preventive safety, power distribution and thermal management in an integrated commercial and industrial energy-storage platform.
Choose Y241 where a 50 kW / 241 kWh air-conditioned cabinet matches the project requirement, or Y261 where a 125 kW / 261 kWh liquid-cooled configuration is required. Final selection should be based on the site load profile, grid connection, photovoltaic input, backup duration, operating environment and applicable local standards.
Integrated cabinet architecture
Long-life battery modules, BMS, PCS, preventive safety, power distribution and thermal management are coordinated in one outdoor system.
Model-specific thermal management
Y241 uses air-conditioning while Y261 uses liquid cooling, allowing selection around power, energy and site requirements.
Parallel expansion
Supports up to 20 parallel units and a system capacity of up to 2 MW / 4.8 MWh; final model-specific sizing requires application engineering.
Environmental adaptability
An IP55 steel enclosure supports operation from -20°C to 50°C and installation at elevations up to 3,000 m.
