Description

The Fox ESS EPS BOX-SP Single-Phase Automatic Backup Switching Box is a high-reliability power continuity solution designed to seamlessly transition to automatic backup power during grid failures in your home or light commercial site. Working in harmony with a compatible Fox ESS battery and inverter system, the backup box ensures your essential circuits remain energised during outages, delivering dependable peace of mind where uninterrupted supply truly matters.

Engineered specifically for single-phase installations, this robust EPS unit handles the full switchover process automatically - eliminating the need for manual intervention and keeping your system running smoothly in all conditions. Its durable IP65-rated metal enclosure provides superior protection against dust, moisture and harsh UK weather, making it ideal for both indoor plant rooms and exposed outdoor locations.

Optimised for clean integration within the Fox ESS ecosystem, the EPS BOX-SP pairs effortlessly with the brand’s leading single-phase hybrid and AC-charger inverter series, including the H1, AC, KH and EVO ranges. Despite its industrial-grade build quality, the unit remains installer-friendly with a practical wall-mounted form factor that simplifies setup and reduces on-site installation time.

Naturally cooled for quiet, maintenance-free operation, the EPS BOX-SP offers long-term reliability without fans or moving parts. Acting as the intelligent control hub between your inverter and backup loads, it ensures your solar-plus-storage system provides resilient, uninterrupted energy even in challenging grid environments. While it does not generate its own power, it switches your property safely onto the inverter/battery backup source whenever required.

  • Automatic Single-Phase Backup Switching: Instantly redirects power from grid to inverter/battery during outages, keeping critical circuits energised without manual input
  • IP65 Weather-Protected Metal Enclosure: Durable, dust-tight and water-resistant housing suitable for both indoor and outdoor installation zones
  • Optimised for Fox ESS Single-Phase Systems: Seamless compatibility with H1, AC, KH and EVO inverter series for fast, clean integration
  • Installer-Friendly Wall-Mounted Design: Robust yet practical enclosure with straightforward wiring layout for efficient installation
  • Silent, Fan-Free Thermal Management: Natural cooling ensures quiet operation, reduced maintenance and long-term durability
  • Reliable EPS Control Hub: Intelligent switching logic coordinates grid, inverter and load connections for safe and stable backup performance
  • Switching Logic: Automatic changeover between on-grid supply and EPS backup mode
  • Compatible Inverters: Single-phase Fox ESS models - H1, AC, KH, EVO series
  • Enclosure Rating: IP65, fully dust-tight and resistant to rain and environmental exposure
  • Construction: Heavy-duty wall-mounted metal enclosure
  • Dimensions (H×W×D): 660mm x 515mm x 235mm | Net Weight: ~19.3kg

Why It Stands Out

  • Automatic Failover - Total Peace of Mind: With intelligent switching logic, the EPS Box‑SP automatically manages backup power transitions without manual intervention.
  • Built for All Climates: Its hardy construction and robust IP rating mean reliable operation across a variety of environmental conditions.
  • Installer-Friendly Form: Compact size and lightweight design make it easy to position within tight spaces, reducing labour and mounting effort.
  • System Compatibility: Specifically designed to work with Fox ESS single-phase ecosystem, ensuring optimal integration and performance.
