FOX-ESS ENERGY CUBE SLAVE CS4800 – 4.8KWH HIGH VOLTAGE LiFePO₄ LITHIUM BATTERY

Product Description

The FOX-ESS Energy Cube Slave CS4800 is a high-voltage LiFePO₄ lithium battery module designed to expand the storage capacity of compatible FOX-ESS Energy Cube systems.

The CS4800 works together with an Energy Cube Master CM4800 to create a scalable high-voltage battery system. Additional CS4800 Slave modules can be added to increase the overall storage capacity, with FOX-ESS specifying configurations of up to six CS4800 Slave modules with one CM4800 Master in the ECS4800 range.

The battery uses LiFePO₄ prismatic cell technology and is designed for reliable energy storage in residential and commercial solar installations.

Modular Energy Storage

The CS4800 Slave is designed to be combined with the CM4800 Master to create an Energy Cube battery stack.

FOX-ESS lists the following ECS4800 configurations:

CM4800 + 1 × CS4800
CM4800 + 2 × CS4800
CM4800 + 3 × CS4800
CM4800 + 4 × CS4800
CM4800 + 5 × CS4800
CM4800 + 6 × CS4800

This provides a scalable storage solution for different energy requirements.

Ideal Applications

The FOX-ESS CS4800 is suitable for compatible:

Residential solar PV systems
Home energy-storage systems
Solar backup power
Hybrid solar installations
Renewable-energy storage
Solar self-consumption
Small commercial energy-storage systems
Backup-power applications

LiFePO₄ Battery Technology

The CS4800 uses LiFePO₄ prismatic cells, providing a robust chemistry for stationary energy storage.

FOX-ESS specifies a 90% depth of discharge and a cycle life of 6,000 or more cycles under the manufacturer’s stated test conditions.

Protection & Communication

The battery incorporates battery-management and protection functions and communicates with compatible system equipment via CAN.

The IP65 protection rating allows the battery to be installed in suitable indoor or outdoor environments, subject to the manufacturer’s installation requirements.

Installation & Compatibility

Important: The CS4800 is a Slave battery module and is designed to operate as part of a compatible FOX-ESS Energy Cube system. It is not intended to be used as a standalone battery.

Before purchasing, confirm compatibility between the CS4800, CM4800 Master, FOX-ESS inverter and other required system components.

High-voltage battery systems should be installed and commissioned by appropriately qualified personnel in accordance with FOX-ESS installation requirements.
