FOXESS EPS BOX-PRO-G

FOXESS EPS BOX-PRO-G: Enterprise-grade automatic emergency power switching for uninterrupted energy independence

The FOXESS EPS BOX-PRO-G is the ultimate three-phase hardware solution for residential and commercial solar installations that require uncompromising power supply security during grid outages. As a fully automatic switching terminal, the box reliably disconnects the home grid from the public power grid in an emergency and directs the inverter's energy straight to critical loads. By omitting the RS-485 meter port, this variant optimizes system complexity and is perfect for setups where smart meter communication is already handled autonomously or directly via the inverter.

Highlights of the FOXESS EPS BOX-PRO-G system control

• Fully automatic off-grid switching: Instantly detects irregularities in the supply grid and automatically and safely switches loads to off-grid emergency power mode.
• Optimized interface architecture: Designed as a "G" specification without an integrated RS-485 meter connection to minimize installation errors and eliminate system conflicts with external smart meter structures.
• High current carrying capacity: Designed for demanding load profiles with a maximum continuous current of up to 63 A per phase on the grid and load side.
• Safe grid disconnection: Protects maintenance technicians in the event of a power outage through reliable physical separation (all-pole disconnection) in accordance with common application regulations.
• Visual diagnostic panel: The integrated LED status indicator inside allows for quick and clear visual verification of the current switching state of the normal and backup power sides.

Highlights regarding hardware robustness & installation

• IP65 weather resistance: The extremely robust, sealed housing offers maximum protection against dust ingress and water jets, allowing for installation indoors and in protected outdoor areas.
• Fanless passive cooling: Operates completely silently and wear-free using natural convection, as it eliminates the need for susceptible mechanical fans.
• Wide temperature spectrum: Delivers unrestricted performance within a broad thermal operating window from icy -25 °C to hot +60 °C (derating from 45 °C).
• Ergonomic wall mounting: The housing dimensions and well-thought-out mounting system are optimized for quick, reliable installation by a single technician.
• Industrial-grade connection terminals: Generously dimensioned, stable terminals inside the housing ensure convenient cable routing and permanently vibration-resistant contacts.

Technical specifications: FOXESS EPS BOX-PRO-G

Professional advantage: The FOXESS EPS BOX-PRO-G is the technological secret weapon for solar installers and electrical contractors to realize three-phase backup systems as cost-effectively and error-free as possible. The deliberate omission of the internal RS-485 meter path completely eliminates time-consuming troubleshooting in parallel-connected bus systems or external measuring devices. This pre-assembled all-in-one switching unit replaces complex and error-prone contactor circuits in the distribution board, drastically reducing pure installation and wiring time on site. With its IP65 certification and massive 63 A load capacity, it offers durable industrial quality that effectively prevents costly warranty claims and subsequent service calls.
