Fox ESS Thee Phase EPS Box Pro HC - Whole Home Back Up Box

Fox ESS EPS Box Pro-HC – Three-Phase Whole-Home Backup Box

The Fox ESS EPS Box Pro-HC is a three-phase automatic changeover device designed to provide reliable whole-home backup power when the grid supply fails. Used with compatible Fox ESS three-phase hybrid inverters, the EPS Box Pro-HC automatically switches the installation between normal grid operation and backup power, helping maintain the supply to connected loads during a power outage.

Designed for residential and commercial Fox ESS energy storage systems, the EPS Box Pro-HC provides a practical solution for installations requiring three-phase backup capability. Its automatic changeover functionality allows the system to transition between grid-connected and backup operation without requiring manual intervention.

Three-Phase EPS Backup for Fox ESS Energy Storage Systems

When connected to a compatible Fox ESS inverter and battery storage system, the EPS Box Pro-HC enables backup operation across a three-phase installation. In the event of a grid failure, the system can automatically transfer the connected supply to the inverter's emergency power supply output.

This makes the Fox ESS EPS Box Pro-HC particularly suitable for installations where maintaining power to important household or commercial loads during a mains failure is required. It provides the automatic switching hardware required for compatible Fox ESS three-phase backup systems.

Automatic Grid-to-Backup Changeover

The EPS Box Pro-HC is designed to automatically manage the transition between the normal grid supply and the inverter's backup supply. This removes the need for manual changeover during a power cut and provides a streamlined solution for Fox ESS whole-home backup installations.

With support for up to 63A per phase, the EPS Box Pro-HC is suitable for a wide range of three-phase residential and commercial applications, subject to the design requirements of the installation and the specifications of the connected Fox ESS inverter system.

Always check the latest Fox ESS compatibility documentation for the exact inverter model before installation. Compatibility, backup configuration and maximum supported loads should be confirmed against the specific inverter and system design.

Robust IP65 Enclosure

The EPS Box Pro-HC features a durable IP65-rated metal enclosure, providing protection suitable for the intended installation environment. Its wall-mounted format keeps the changeover equipment contained within a dedicated enclosure while providing a clean and practical installation solution.

Ideal for Whole-Home Backup

The Fox ESS EPS Box Pro-HC three-phase backup box is suited to installations where a Fox ESS battery storage system is being configured to provide backup power to a three-phase property. Depending on the overall system design, it can be used as part of a solution intended to keep essential or whole-property loads supplied during a grid outage.

It is particularly relevant for larger homes, three-phase properties, commercial premises and other installations using compatible Fox ESS hybrid inverter and battery storage equipment.
