  • Key Features
  • Technical Specifications

The Entelar Backup Box-B1 (Three-Phase) is a robust backup power switching device designed to integrate with three-phase Entelar inverter systems. When grid power fails, it automatically switches essential circuits to backup mode, delivering reliable power to critical loads. Once the grid is restored, it seamlessly reverts to grid-connected operation. Built for durability, it features outdoor-rated protection and compatibility with a wide range of Entelar three-phase inverters.

  • Automatic grid-to-backup switchover in under 3 seconds.

  • Designed for three-phase grid input (380-400 V), but supplies backup load in single phase. 

  • Maximum passing (grid) current of 40 A

  • Backup capacity of 3,300 VA with maximum backup output current of about 15.2 A. 

  • Rated for wide voltage ranges: grid connection 342-440 V AC; backup output from 220-230 V AC.

  • IP65 enclosure — protected from dust and water jets; suitable for indoor or sheltered outdoor installation.
