Fox EQ5000, 4.92kWh HV Battery (Slave) #2: FE-HV-EQS-5000 Storage Systems - Li-ion Battery Pack Fox EQ5000 Datasheet Fox Product Compatibility Fox EQ5000 Warranty 🔋 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 1 × Master battery Up to 5 × Slave batteries 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. ⚡ Battery Performance & Energy Storage 90% Depth of Discharge The Fox ESS EQS5000 supports a 90% depth of discharge (DoD), allowing a significant proportion of stored energy to be utilised within a compatible battery system. 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: A non-heated master module can be connected to heated slave modules. A heated master module 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. ⚠️ Warranty Registration Information Activate Your 10-Year Product Warranty The Fox ESS installation must be registered online to activate the 10-year product warranty.
