Outdoor Battery Cabinet, 261kWh Liquid-Cooled LFP Battery, IP55 Weatherproof, 832V Nominal Voltage, 130kW Max Discharge Power, Efficient Cooling

This outdoor battery cabinet is a high-performance energy storage solution designed for demanding commercial and industrial applications. It integrates advanced liquid cooling technology and lithium iron phosphate (LFP) battery cells to deliver reliable power backup and peak shaving capabilities. With a compact footprint of just 1.3 square meters, it offers flexible deployment even in space-constrained outdoor environments, while its robust IP55 enclosure ensures protection against dust and water jets, making it suitable for harsh weather conditions.

The system delivers a rated capacity of 261.2 kWh and a usable capacity of 235.1 kWh, with a maximum continuous output power of 130 kW. Operating at a nominal voltage of 832 V and covering a wide voltage range from 728 V to 936 V, it supports a charge/discharge rate of up to 0.5P, ensuring stable and efficient energy transfer for high-load scenarios. The integrated control module manages all power distribution and communication via a CAN interface, guaranteeing precise monitoring and responsive operation.

At the core of the cabinet are five identical battery modules, each featuring a capacity of 52.25 kWh and utilizing LFP chemistry known for its long cycle life and thermal stability. The modules are intelligently managed by a dedicated battery management system that maintains cell temperature difference within 2.5°C, thanks to the efficient liquid cooling loop. This design not only prolongs battery life but also enhances overall system safety and performance consistency, while the cabinet’s total weight remains under 2400 kg, allowing for straightforward floor-standing installation.

The cabinet measures 1000 mm in width, 1300 mm in depth, and 2200 mm in height, with a net weight of less than 2400 kg. It is equipped with status indicator lights for at-a-glance system health monitoring and supports remote fault diagnosis and software upgrades, simplifying on-site maintenance. The liquid cooling system ensures optimal thermal management even under high ambient temperatures, and the unit comes with a standard 5‑year warranty for peace of mind.

Designed for extreme environments, this cabinet operates reliably in temperatures ranging from -25°C to +55°C, with derating applied above 45°C. It can be stored under various temperature conditions with specific SOC limits, and it functions properly at relative humidity levels between 5% and 95%. The maximum operating altitude is 3000 meters, with derating above 2000 meters. The product complies with international standards including UN38.3, IEC 61000, IEC 61619, IEC 60730, REACH, and IEC 62477‑1, ensuring full regulatory compliance and safety for global deployment.
