Product Overview
The Freedom Won eTower e5000 is a modular 52V LiFePO4 battery designed for smaller residential and light commercial energy storage applications. With 5kWh total energy capacity, 100Ah current capacity and a stackable design, it is suited to compact solar and backup power systems where reliable lithium battery storage is required.
Key Features
- 5kWh total energy capacity with 4kWh usable energy at 80% depth of discharge and 4.5kWh at 90% depth of discharge.
- 52V nominal battery voltage designed to suit 48V inverter systems, with a specified operating range of 47V to 56V.
- LiFePO4 battery chemistry for stable, long-life energy storage in residential and light commercial installations.
- Supports CAN Bus, RS485 and RS232 communication interfaces for compatible inverter, controller and service connections.
- Integrated electronic protection includes overcurrent, cell under-voltage, cell over-voltage, temperature out-of-range, weak cell detection and minimum SOC control.
- Compact steel enclosure rated for indoor use only, away from direct sun and other heat sources.
Applications
- Residential solar energy storage systems.
- Small backup power systems using compatible 48V inverter equipment.
- Light commercial battery storage installations.
- Modular systems where additional eTower battery capacity may be required, subject to system design and compatibility confirmation.
Why Choose This Product?
The Freedom Won eTower e5000 offers a compact, modular lithium battery option for users who need dependable energy storage without moving into a larger battery platform. Its stackable format, communication interfaces and integrated BMS protection make it a practical choice for qualified installers designing smaller 48V solar and backup systems.
