FLB48280TG1-AU is a lithium iron phosphate (LiFePO4) battery storage solution designed for household use, delivering 14.3kWh of nominal energy at a 51.2V nominal voltage. Developed to meet customer and market demands, it provides reliable power for various devices and features a long lifespan, suitability for high-temperature environments, and a compact, floor-mounted design requiring minimal installation space. The product incorporates an independently developed battery management system (BMS) with multiple protections, including a breaker, fuse, and MX+OF. When connected to a grid or photovoltaic system, it stores energy by charging; during a power outage, it independently supplies electricity to household loads. Multiple units can be connected in parallel to form a high-capacity, multi-module system, meeting long-term energy storage requirements.
