The BI-NUSGN-01 is SolarEdge’s hybrid backup interface designed for seamless integration with the SolarEdge Home Hub / StorEdge systems. It acts as both an import/export meter and an energy routing interface, enabling full or partial home backup during grid outages while mediating power flow under normal conditions.

Key Features & Benefits

• Dual Functionality
  Acts as a backup interface plus an import/export metering device — combining functionality to simplify wiring and reduce components. 

• Automatic Load Isolation & Backup
  In case of grid failure, it isolates loads from the grid and routes power from PV + battery to selected loads. 

• Integrated Current Measurement & Auto-Transformer
  Includes built-in meter and auto transformer to manage current flows and support split-phase balancing.

• Load-Side Installation (No Main Breaker Needed)
  The BI-NUSGN-01 is the “load-side” version, meaning it installs between the main panel and loads, without requiring the main breaker to be altered. 

• High Backup Capability
  Supports short-term surge (peak) AC power during backup operation — up to ~7,000 W for < 10 seconds. 

• Robust Construction & Compatibility

  • 240 V nominal AC output, 60 Hz frequency matching U.S. grid standards 

  • Dimensions: 20.59 in × 13.88 in × 8.62 in; Weight: ~ 73 lb 

  • Compatible with SolarEdge Home Hub / StorEdge inverter + battery systems
