Felicity Solar 5.12kWh 48V LiFePO4 Battery – High-Cycle Lithium Energy Storage Module
Felicity Solar 5.12kWh Lithium Battery Overview
The Felicity Solar 5.12kWh LiFePO4 battery (FLA48100) is a high-performance 48V lithium battery designed for residential, commercial, and off-grid solar energy storage systems. Built using Lithium Iron Phosphate (LiFePO4) technology, this 5.12kWh lithium battery delivers long cycle life, high safety, deep discharge capability, and stable performance for daily energy storage applications.
The Felicity Solar 5.12kWh battery is ideal for use with hybrid and off-grid inverters, providing reliable backup power during load shedding and supporting solar self-consumption in battery-based systems.
LiFePO4 Battery Chemistry & Safety Advantages
The Felicity Solar 5.12kWh lithium battery uses advanced LiFePO4 chemistry, which is widely regarded as one of the safest lithium battery technologies available. Compared to traditional lithium-ion or lead-acid batteries, LiFePO4 offers superior thermal stability, reduced fire risk, and a significantly longer lifespan.
An integrated smart Battery Management System (BMS) continuously monitors voltage, current, temperature, and state of charge to protect against overcharge, over-discharge, over-current, overheating, and short circuits.
Usable Capacity & Depth of Discharge Performance
The Felicity Solar 5.12kWh LiFePO4 battery supports a depth of discharge (DoD) of up to 95%, allowing most of the stored energy to be safely used without reducing battery lifespan. This ensures maximum usable capacity and longer runtime during power outages or off-grid operation.
With a nominal capacity of 5.12kWh, this lithium battery is well suited for essential household loads such as lighting, internet equipment, televisions, refrigeration, and office electronics when used individually, or for larger systems when installed in parallel.
High Charge & Discharge Capability
The Felicity Solar 5.12kWh battery supports a recommended charge and discharge current of ≤100A, with a maximum charge and discharge current of up to 150A. This allows the battery to support high-load demand and inverter surge requirements when correctly sized and installed.
High current capability ensures stable voltage output under load, improving inverter performance and system reliability.
Scalability & Parallel Expansion
The Felicity Solar 5.12kWh lithium battery is designed for parallel connection only and does not support series wiring. The system supports scalability of up to 15 battery units connected in parallel, enabling total storage capacity of up to 76.8kWh.
This modular design makes the Felicity Solar 5.12kWh battery ideal for customers who want to start with a single unit and expand their battery bank as energy demand increases.
Inverter Compatibility & Communication
The Felicity Solar 5.12kWh battery supports RS485 and CAN communication protocols, allowing seamless integration with Felicity Solar inverters and many other compatible 48V hybrid and off-grid inverter brands.
Communication between the battery and inverter enables accurate state-of-charge reporting, controlled charge and discharge behaviour, and optimized battery lifespan.
Installation Flexibility & Physical Design
The Felicity Solar 5.12kWh LiFePO4 battery features a compact, modern metal enclosure suitable for wall-mounted or floor-mounted installation. Its slim profile allows for neat installation in garages, utility rooms, battery rooms, and plant rooms.
The built-in LCD display provides real-time battery information such as voltage, current, state of charge, and fault indicators, making system monitoring simple and intuitive.
Environmental Performance & Operating Conditions
The battery is designed for indoor installation and operates within a charging temperature range of 0°C to 55°C and a discharging temperature range of -20°C to 55°C. This makes it suitable for most residential and commercial indoor environments.
