5kWh Felicity FLA48100 48V 100Ah Battery with Built-In WiFi Module

The 5kWh Felicity FLA48100 combines a 48V 100Ah battery platform with a built-in WiFi module, making it a connected storage option for compatible 48V solar and backup systems.

Its 5kWh capacity provides substantial stored energy from a single battery unit, making the FLA48100 particularly relevant to residential and small-business installations that need more than basic essential-load backup.

A defining feature of this exact FLA48100 model is its built-in WiFi module. This adds integrated connectivity without requiring the WiFi module to be installed as a separate external accessory.

Technical Specifications

Key Features

• Exact Felicity model FLA48100

5kWh Storage Capacity

The FLA48100 provides 5kWh of supplied battery capacity, giving a compatible solar system a substantial amount of stored energy for later use.

It can be used to store solar energy generated during the day and make that energy available when solar production reduces or during grid interruptions, depending on the overall system configuration.

Actual backup duration depends on the connected load, usable battery energy, inverter efficiency and system settings.

Native 48V 100Ah Configuration

The FLA48100 provides:

48V | 100Ah | 5kWh

from a single battery unit.

This makes it particularly suited to compatible 48V-class inverter systems without needing multiple lower-voltage batteries simply to establish the nominal 48V battery platform.

The inverter’s exact operating voltage and charging requirements must still be compatible with the battery.

Built-In WiFi Module

The built-in WiFi module is one of the main distinguishing features of the FLA48100.

Rather than requiring WiFi to be added as a separate module, connectivity is integrated into this battery model.

The exact monitoring functions, supported application, available battery data and WiFi setup procedure should be confirmed from Felicity’s documentation for the FLA48100.

Why 48V Matters

A 48V battery platform is commonly relevant to higher-power solar and backup installations compared with lower-voltage battery architectures.

For the FLA48100, however, inverter selection should be based on more than the 48V designation. The inverter’s permitted battery-voltage range, charging parameters and battery compatibility requirements should all be checked.

Applications / Use Cases

☀️ 48V Solar Systems – 5kWh battery storage for compatible 48V solar installations.

🏠 Home Backup – stored energy for appropriately calculated household essential loads.

🏪 Small Businesses – suitable for correctly sized business backup requirements.

💻 Home Offices – useful for selected electronics and essential equipment.

📶 Connected Solar Storage – built-in WiFi makes the FLA48100 suitable where compatible connected battery functionality is required.

Battery & Inverter Matching

Before pairing the FLA48100 with an inverter, verify:

• Compatible 48V battery platform
• Required storage capacity
• Battery charging requirements
• Battery discharge capability
• Inverter battery-voltage range
• Communication requirements, where applicable
• Correct DC cable sizing
• Suitable DC protection
• WiFi configuration requirements

Charge current, discharge power, DOD, cycle life and communication protocol were not supplied for this exact model, so these specifications should be confirmed rather than assumed from other Felicity batteries.

Usage & Installation Notes

• Match with a compatible 48V inverter system
• Configure charging according to the FLA48100 specifications
• Use correctly sized battery cables
• Install appropriate DC protection and isolation
• Observe correct polarity
• Protect terminals against accidental short circuits
• Follow Felicity installation requirements
• Configure the built-in WiFi according to the manufacturer’s instructions
