Fox ESS ECS HV ECM4800-2H Full Stack Battery System 32.61kWh (1x Master, 6x Slave)

The Fox ESS ECS HV ECM4800-2H full stack is a high voltage lithium ion battery storage system delivering 32.61kWh of useable energy in a single, complete stack. Built around the ECS modular platform, this configuration combines one master module with six slave modules to provide a robust, scalable solution suitable for advanced residential and commercial energy storage applications.

Included Battery Modules

• 6 x Fox ECS EC4800-2H 4.74kWh High Voltage Battery Slave Modules (FE-HV-ECS-4800)
• 1 x Fox ECS EC4800-2H 4.74kWh High Voltage Battery Master Module (FE-HV-ECM-4800)

System Scalability and Architecture

The ECS HV platform is designed with a modular, series connected architecture that allows additional battery modules to be added after initial installation. A minimum of two modules is required for operation, consisting of one master and one slave. A single stack supports up to seven modules in total, enabling expansion up to 33.2kWh depending on configuration.

Why the ECS HV Series Stands Out

• High voltage battery design optimised for hybrid and AC coupled systems
• 90% depth of discharge for effective utilisation of stored energy
• CAN and RS485 communication for reliable inverter integration
• Wide temperature tolerance for varied installation environments
• Quick and simple plug and play installation process

Installation and Compatibility Notes

This battery system must be installed by a qualified electrician or technician in accordance with local wiring regulations and standards. To operate with the Fox ESS H3 and AC3 inverter ranges, a minimum stack of five battery modules is required to meet voltage requirements. Installation must be registered with Fox ESS to activate the 12 year product warranty. Without registration, a 5 year warranty applies as standard.
