The Fox ESS EQM5000 supports CAN and RS485 communication, enabling communication between compatible battery modules and the wider energy storage system.
High-Voltage Modular System
The EQ range is designed as a scalable battery storage platform, making it suitable for installations where additional energy storage capacity may be required in the future.
Battery Compatibility When Expanding an Existing System
Adding Modules to an Existing EQ Battery Stack
If you are adding new battery modules to a pre-existing Fox ESS EQ battery stack, it is important to ensure that the new modules are compatible with the original battery modules.
Before purchasing or installing additional modules, contact your technical support representative through the relevant portal and provide a photograph of the existing battery stack to help confirm compatibility.
Heated & Non-Heated Battery Compatibility
Mixed Battery Configurations
Heated and non-heated battery versions can be used together within the same compatible EQ battery system.
For example:
A non-heated master can be connected to heated slave modules.
A heated master can be connected to non-heated slave modules.
However, if any battery module within the system does not support heating, the heating function will be disabled for the entire battery system.
