Felicity Solar FLB48100WG1-H 5.12kWh 51.2V 100Ah IP65 LiFePO4 Solar Battery

Compact 5.12kWh Solar Battery for Residential PV Systems

The FLB48100WG1-H offers 5.12kWh nominal energy in a compact, installer-friendly format. This capacity is widely used in residential solar battery systems where the customer wants to store surplus solar energy, increase self-consumption and reduce grid dependence.

For solar installers and electricians, the 51.2V 100Ah specification is easy to quote, easy to compare and suitable for many low-voltage energy storage systems. The battery can be used as a single storage unit or expanded in parallel where more capacity is required.

IP65 Protection for Flexible Installation

The IP65 protection level makes the FLB48100WG1-H suitable for more flexible installation environments compared with indoor-only battery systems. The datasheet presents the FLB Series as a 51.2V low-voltage LiFePO4 battery range with IP65 protection, remote monitoring, fire protection module, scalable parallel expansion and easy fuse replacement design.

For professional solar PV projects, this is useful when the battery must be installed in garages, technical rooms, utility areas or protected installation spaces where a more robust casing is required.

Wall-Mounted or Floor-Mounted Battery Installation

The Felicity Solar datasheet confirms that the FLB48100WG1-H supports wall-mounted or floor-mounted installation.

This gives installers flexibility during system design. Wall mounting helps save floor space in compact residential installations, while floor mounting can be useful when site conditions, wall structure or service access make floor placement more suitable.

For a clean installation, installers should always follow the Felicity Solar user guide, spacing requirements and local electrical installation standards.

Smart BMS, Breaker and Fuse Protection

The FLB48100WG1-H includes built-in smart BMS, breaker and fuse protection, which are important features for professional energy storage systems.

The BMS supports battery protection and operating stability by helping manage key battery conditions during charge, discharge and system operation. The external fuse replacement design also supports easier service handling when required by qualified personnel.

CAN and RS485 Communication for Hybrid Inverter Systems

The battery supports RS485 and CAN communication, which are commonly used for battery-to-inverter communication in modern solar energy storage systems.

For solar installers and electricians, this is an important procurement detail because inverter compatibility should always be checked before system design and installation. Correct communication setup helps the inverter monitor battery status, manage charge/discharge behavior and protect the system.

Scalable up to 32 Units in Parallel

The datasheet states that the FLB48100WG1-H can be connected up to 32 units in parallel, giving a total scalable capacity of up to 153.84kWh.

This makes the product useful for both small and expandable energy storage systems. A single 5.12kWh battery may be suitable for a compact home system, while multiple units can support larger residential or light commercial projects, subject to inverter compatibility and correct protection design.

Remote Monitoring via FSolar App

The FLB Series datasheet highlights remote monitoring via FSolar App and built-in WiFi/Bluetooth monitoring as product features.

This gives users and installers better visibility of system status. For professional buyers, monitoring is important because it supports easier commissioning, after-sales support and ongoing system checks.
