EcoFlow Gateway Backup Box Single-phase

The EcoFlow Gateway Backup Box Single-phase is an automatic transfer switch and critical load panel designed to provide seamless backup power from Power Ocean hybrid inverters during grid outages for UK residential applications.

Product Description

This single-phase gateway automatically detects grid failure and switches critical household loads to inverter backup power within 20ms. Featuring integrated surge protection, load monitoring, and programmable priority circuits, it enables whole-home or selected backup capability up to the inverter's rated output (3.68-6kW).

Key Features

• Seamless transfer: 20ms switchover time prevents device interruptions.
• Critical load selection: Prioritises essential circuits (lights, fridge, router, heating controls).
• Integrated protection: Type 2 SPD, RCBOs, and overload management.
• Load shedding: Automatic sequential reconnection prevents inverter overload.
• Modbus integration: Real-time status monitoring via EcoFlow app.
• Plug-and-play: Pre-wired for Power Ocean inverters with colour-coded terminals.
