Earth Neutral Bridge Box

  • An essential component for the safe operation of back up and hybrid solar systems up to 5kWAC Back up port power rating.
  • Function is replacing Earth Neutral bridge when system is in backup mode
  • Makes the Earth Leakage to operate correctly on the output of the inverter during backup operation
  • Compatible with the Sunsynk 5kW and Sunsynk 8kW inverters.
  • The ACDB-ARENB-25A automatically creates a temporary earth/neutral bridge when inverter goes to back up mode due to loss of grid, thus avoiding the forming of earth ground loops.
  • Once the backup or hybrid inverter goes into back up mode and disconnects from the utility the existing bridge is lost.
  • This has two side effects that require attention:
    • When a measurement is taken between the Earth and Neutral Conductor on the backup output circuit and elevated neutral voltage is measured.
    • With the Earth/Neutral bridge, any earth leakage device connected in the output circuit does not function correctly.
    • It is essential this ACDB-ARENB-25A is installed between the inverter backup out and the output distribution DB.
