Solplanet ASW125K/261-PT All-in-One Commercial Energy Storage Cabinet

The Solplanet ASW125K/261-PT is a professional all-in-one commercial energy storage system designed for large-scale solar PV systems, industrial energy storage projects, commercial backup power applications and advanced solar battery installations. Combining a powerful 125kW PCS inverter with an integrated 261kWh LiFePO4 battery system, the ASW125K/261-PT delivers a compact, high-efficiency and scalable solution for modern commercial and industrial energy storage applications. The system uses high-performance LiFePO4 3.2V / 314Ah battery cells and features a 1P260S battery configuration with a rated voltage of 832V and operating voltage range from 728V to 936V, ensuring stable and reliable battery operation.

The integrated cabinet design combines PCS and battery modules into one compact enclosure, reducing installation complexity and minimising floor space requirements. With a modular architecture, the system allows fast installation, simplified maintenance and easy future capacity expansion. The ASW125K/261-PT supports up to 137.5kVA apparent power, operates at 400V AC, and provides up to 180A rated current with low harmonic distortion below 3% THD, making it suitable for commercial solar self-consumption systems, peak shaving, backup energy storage and microgrid applications.

The advanced liquid cooling system ensures stable operating temperatures and improves battery lifespan, while the integrated aerosol firefighting system, multi-level electrical protection and PACK-level fault isolation help maximise operational safety. The cabinet supports intelligent real-time monitoring through integrated EMS functionality and multiple communication interfaces including CAN, RS485, Ethernet and 4G connectivity. With a system efficiency above 90%, cycle life exceeding 8000 cycles, and operating temperatures from -25°C to 55°C, the ASW125K/261-PT is engineered for demanding commercial and industrial environments. Additional features include IP55 protection, support for installations up to 4000m altitude, and smart O&M functionality for professional solar installers, solar distributors, solar wholesalers and EPC companies. The Solplanet ASW125K/261-PT is an ideal solution for complete solar kits, solar battery storage systems, commercial PV applications and renewable energy projects requiring reliable long-term energy storage performance.
