🔋 Fox ESS EQS5000 High Voltage Battery Slave – 4.92kWh Modular Storage System
The Fox ESS EQS5000 High Voltage Battery Slave is a modular lithium-ion battery designed for use as part of the Fox ESS EQ high-voltage battery storage system. The scalable design allows compatible battery modules to be added to increase total energy storage capacity as requirements grow.
The EQS5000 works alongside a compatible Fox ESS EQ master battery module and forms part of a flexible battery stack with a maximum system capacity of up to 29.52kWh.
Important: The EQS5000 is a slave battery module and cannot operate independently. A compatible Fox ESS EQ master module is required.
Modular & Scalable Battery Storage
Expandable Up to 29.52kWh
The Fox ESS EQ battery system uses a modular design that allows compatible battery modules to be connected together to increase total energy storage capacity.
A compatible battery stack requires:
-
Minimum configuration: 2 modules
-
1 × Master battery
-
1 × Slave battery
-
Maximum configuration: 6 modules
-
Maximum system capacity: Up to 29.52kWh
This flexible configuration allows the battery storage system to be expanded as energy requirements increase.
Easy Plug-and-Play Installation
The modular design supports straightforward installation and system expansion, helping installers save time when assembling compatible Fox ESS EQ battery stacks.

Charging & Discharging Performance
The battery module is designed to support reliable energy storage and delivery when installed as part of a compatible Fox ESS EQ system.
Performance specifications include:
-
Continuous discharge rate: 1,440W
-
Maximum discharge rate (5 minutes): 2,880W
-
Surge discharge rate (15 seconds): 3,000W
-
Maximum charge rate (5 minutes): 2,880W
Communication & System Integration
CAN & RS485 Communication
The EQS5000 supports CAN and RS485 communication, allowing compatible battery modules to communicate within the wider energy storage system.
Designed for High-Voltage Battery Systems
The EQ battery range is designed as a scalable energy storage platform, providing flexibility for installations that may require additional battery capacity in the future.
Adding Batteries to an Existing EQ Stack
Check Module Compatibility Before Expansion
If you are adding an EQS5000 battery module to an existing Fox ESS EQ battery stack, it is important to confirm that the new battery is compatible with the existing modules.
Before installation, contact your technical support representative through the relevant portal and provide a photograph of the existing battery stack to help determine compatibility.
Heated & Non-Heated Battery Compatibility
Mixed Battery Configurations
Heated and non-heated Fox ESS EQ battery versions can be used together within the same compatible battery system.
For example:
However, if any battery module within the system does not support heating, the heating function will be disabled for the entire battery system.
