Fsolar Lithium Battery 120AH 51.2V 6kWh LiFePO4 Alpha Series

The FSOLAR FSESS 6KWh is a professional-grade energy storage solution engineered with advanced Lithium Iron Phosphate (LiFePO4) technology to deliver dependable power for residential appliances and off-grid systems. Operating at a nominal voltage of 51.2V with a 120AH capacity, this module is protected by an intelligent Battery Management System (BMS) that monitors over-voltage, low-voltage, and temperature while providing surge and AC short-circuit protection. Encased in a robust housing with an IP55 ingress protection rating, the unit weighs approximately 60 kg and supports flexible communication through RS485, RS232, CAN, and UART interfaces.

Designed for long-term efficiency and scalability, the battery supports the parallel connection of up to 6 units to meet larger power demands. It operates effectively across a wide temperature range, from -20°C during discharge to 60°C during charging, and is optimized for an optimum charge current of 60A and a maximum continuous discharge of 100A. With a cycle life exceeding 6,000 cycles, this maintenance-free 6kWh system provides a modern and durable power solution that can be monitored via cloud and mobile applications.
