Fox ESS Energy Cube ECM4800 Master: The High-Capacity Hub for Your 4.74kWh+ HV Battery System

Power your home with the high-performance Fox ESS Energy Cube ECM4800 Master Battery. As the control unit for the ECS4800 series battery energy storage system, this 4.74kWh high-voltage (HV) module provides a substantial starting point for significant energy storage. Store abundant energy from your solar panels to use whenever you need it, drastically reducing reliance on the grid, navigating peak energy tariffs, and ensuring greater energy security. It integrates seamlessly with compatible Fox ESS hybrid or AC inverters.

Robust High-Voltage Storage with LiFePO4 Cells

The ECM4800 Master unit delivers a nominal capacity of 4.74kWh (based on 1/3C discharge rate information in the datasheet) using dependable LiFePO4 prismatic cells, known for safety and longevity. The technical data highlights excellent performance characteristics, including over 95% round-trip efficiency and a 90% depth of discharge, allowing you to utilize most of the stored energy. This high-capacity module is ideal for households with significant energy consumption.

Unmatched Scalability for Future Energy Needs

The Fox Energy Cube 4800 series excels in scalability. Starting with this ECM4800 Master, you can add up to six ECS4800 Slave modules. This modular approach, confirmed by the datasheet, allows system expansion from 4.74kWh (Master only - requires slave for operation) up to a massive 33.24kWh (1 Master + 6 Slaves). This makes it perfect for large homes or those anticipating increased future energy usage, such as adding an electric vehicle.

Simplified Installation and Enduring Quality

Fox ESS engineers the ECS system for ease of installation. The product details mention a 'plug and play', stackable design, saving time and effort during setup. Rated at IP65, the system is resilient against environmental factors, suitable for indoor or outdoor floor-standing installation. A long operational life is expected, with a cycle life specified as ≥6000 cycles, supported by Fox ESS's warranty (check documentation for details).
