The Felicity Solar FLH48314UG1MN is a modular high-voltage LiFePO₄ battery storage system for commercial, industrial, and large residential energy systems. Scalable from 5 to 16 modules per tower and with up to 16 clusters in parallel, the system achieves a maximum total capacity of 4.1 MWh – ideal for load management, self-consumption optimization, peak shaving, and professional energy storage solutions.
The LFP cell chemistry ensures maximum thermal stability, long service life, and maximum safety. An integrated fire protection module , smart BMS , MCCB protection , air-cooling thermal management , and a touch display make the system particularly reliable and user-friendly.
With ≥ 8000 cycles , 90% DoD , remote monitoring via the FSolar app and extensive communication interfaces (RS485, CAN, Ethernet, WiFi), the FLH48314UG1MN is a future-proof solution for professional energy storage projects.
