LiFe3851 Applications : Scalable 48V Battery for solar systems
LiFe4851 48V battery for safe storage
PowerPlus Energy’s LiFe3851 is a 3RU, 48V lithium-iron phasphate battery designed for residential and commercial energy storage. Certified to UL1973 and UL9540A, it delivers electrical and thermal safety, integrated protection hardware and scalable parallel capability.
Battery Installation Flexibility
Multi-mode Compatible. Managed or Self-Managed.
As an installer, select your preferred operating battery mode, self-managed or managed. Engineered for additional installation flexibility across a wide range of energy storage system requirements. LiFe4851 integrates protection and communication compatibility to streamline commissioning and system configuration.
- In managed mode integrate smart inverters and access system data such as accurate SoC reporting, predictable capacity and SoH. Greater system visibility and detailed fault detection across all connected equipment.
- Self-managed mode increases PCE integration flexibility and is built-in as a redundancy to managed mode in the event of comms connectivity issues.
Advanced built-in Battery Management System.
Engineered Protection at Every Level.
The LiFe4851 integrates a BMS that monitors, protects and balances the complete battery pack. Unlike cell-level-only certification approaches, the entire system, including cells, electronics, enclosure and protection hardware is tested and validated under fault conditions.
Complete System Monitoring
Continuous monitoring of voltage, temperature, current and isolation integrity.
Fault Protection
Protection against overcharge, over-discharge, short circuits (internal and external) and thermal stress.
Active Cell Balancing
Each individual cell is continuously balancing throughout the charge cycle to ensure battery health down to a cell level and promote longevity.
CANBus Communications
Enables seamless integration with compatible smart inverters and PCE Platforms.
Industry Standard Temperature Range
-20°C to 60°C Designed to safely manage charging and discharging across Australia’s diverse climate conditions.
