Product Overview
The CONLUXS MAXPOWER-261 is an all-in-one liquid-cooled energy storage system designed for commercial and industrial energy storage and utility-scale battery storage projects. It integrates a 261 kWh high voltage battery pack, PCS, BMS, EMS and an advanced liquid cooling and fire protection system. Precise thermal control keeps the cell temperature difference within 2.5°C to extend battery life, while early thermal runaway warning, gas detection and automatic fire suppression strengthen safety. The system operates as a high voltage DC power supply for grid-tied, off-grid and micro-grid applications, including virtual power plants and renewable energy integration. Factory-prefabricated modular construction reduces installation and commissioning costs, and cloud-based monitoring with AI-driven predictive maintenance lowers O&M complexity.
