Felicity FLB48314TG1-H 16kWh 51.2V LiFePO4 home battery (IP65)

The Felicity FLB48314TG1-H is a powerful low-voltage (51.2V) LiFePO4 battery storage system for homes and small-scale applications. Ideal in combination with a compatible (hybrid) inverter/PCS to store solar energy, increase self-consumption, and mitigate peak demand. By connecting in parallel, the system can easily be expanded to larger capacities.

Installation and expansion

A suitable (hybrid) inverter/PCS with CAN or RS485 communication, or with settings for a 51.2V LFP battery, is required for connection. The battery supports paralleling for capacity expansion; for multiple units, a combiner box or busbar solution is typically used. Ensure proper DC protection, grounding, and sufficient ventilation around the enclosure. Installation must be carried out by qualified personnel.
