Felicity Solar FLB48314TG1-H 16kWh 51.2V Heated IP65 LiFePO4 Battery Pack

Heated Version for Cold-Weather Battery Support

This is the heated version, identified by the “-H” in the model name FLB48314TG1-H. The user manual shows that the battery status indicator can display heating status, including a yellow light flashing slowly at a frequency of one second to indicate that the unit is in heating status.

The manual also lists the recommended charging temperature range as 0°C to +55°C and discharging range as -20°C to +55°C, which makes the heated version especially relevant for European projects where battery storage may be installed in colder utility rooms, garages, outdoor-protected areas or semi-exposed technical spaces.

For installers, this helps position the FLB48314TG1-H as a stronger choice than a standard indoor-only battery when the project requires better environmental resilience.

IP65 Protection for Harsh Installation Conditions

The FLB48314TG1-H is listed with IP65 protection, making it suitable for harsher environments than standard indoor IP21 battery systems. The datasheet specifically highlights “Resist harsh environment with IP65-rate protection”, and the user guide also confirms IP65 protection in the technical appendix.

This is an important selling point for European installers and electricians because many battery installations are placed in garages, utility rooms, outbuildings, plant rooms and protected outdoor locations. Final installation must still follow the manufacturer manual and local electrical regulations.

16kWh Capacity in a 51.2V Low-Voltage Battery Pack

The Felicity Solar FLB48314TG1-H provides 16kWh nominal energy with 314Ah nominal capacity and 51.2V nominal voltage. This makes it suitable for residential energy storage systems, larger self-consumption projects, backup-ready hybrid systems and small commercial PV storage applications.

Compared with smaller 5kWh battery modules, a 16kWh unit can reduce the number of separate battery packs required for many home and light commercial projects. This can simplify procurement, installation planning and system layout.

Scalable up to 32 Units in Parallel

The datasheet confirms that the FLB48314TG1 can scale up to 32 units in parallel, reaching up to 512kWh total capacity.

This gives installers and EPC contractors flexibility. One battery can serve a residential project, while multiple units can be used for larger homes, commercial energy storage, backup power systems or phased expansion projects.

The user manual also includes diagrams for parallel battery connection and recommends using a battery pack combiner box or copper busbar when paralleling multiple battery packs.

Built-in Smart BMS, Breaker and Fuse

The FLB48314TG1-H includes built-in smart BMS, breaker and fuse protection. This is clearly listed in the datasheet and user manual.

For professional installers, this is important because protection and monitoring are central to safe battery operation. The battery’s management system includes voltage protection, current protection and fault handling functions, which are described in the user manual’s BMS section.

Built-in WiFi/Bluetooth Remote Monitoring

The datasheet lists built-in WiFi/Bluetooth for remote monitoring, and the user manual includes instructions for managing devices through the FSolar App and network setup.

This allows battery pack data to be monitored more easily, supporting both end-user visibility and installer service follow-up. For modern energy storage systems, remote monitoring is a strong selling point because it reduces uncertainty after installation.

RS485 and CAN Communication for Hybrid Inverter Compatibility

The FLB48314TG1-H supports RS485/CAN communication, which is essential for battery-inverter communication in professional hybrid solar systems.

The datasheet also states compatibility with leading inverter brands, while the user manual includes communication port information for inverter connection. Installers should still confirm compatibility with the latest Felicity Solar inverter compatibility list before installation.

External Fuse Design and Aerosol Fire Extinguishing System

The datasheet highlights a patented external fuse design and an aerosol fire extinguishing system.

These features are important for professional battery storage projects because they support serviceability and safety-focused system design. The external fuse design can make fuse replacement more practical, while the aerosol fire extinguishing system is a strong safety feature for buyer confidence.
