J Series

  • Prime Output 5.5 kVA (5.5 kW)
  • Standby Output 6.0 kVA (6.0 kW)
  • Frequency: 50 HZ
  • Phase: Single
Features & Benefits


  • The generator and the engine are direct-coupled to ensure a more reliable power supply with minimum power loss.
  • The J-Series uses a transistor AVR to ensure a stable flow of current for most jobs.
  • The waveform distortion is kept to a minimum by the skewed rotor, while the damper winding protects the generator during short circuits, regulates voltage fluctuations during condensive loads, and withstands load fluctuations during condensive and non-linear loads.

Clean Emissions

  • This generator uses Kubota original E-TVCS combustion to produce less soot, HC and CO emissions.

Easy Operation

  • Advanced design and engineering minimized both space and weight for easy use and storage.
  • Key switch, voltage meter, circuit breaker, and warning lamps are all conveniently gathered on a drip proof control panel.
  • The larger capacity fuel tank enables longer periods of continuous operation on a single tank.


  • One-point lifting eye and special forklift openings enhances transportability.

Simple Maintenance

  • Most gauges and filters are conveniently situated to simplify daily maintenance.
  • A double element air filter is used in the J-Series for heavy-duty use, and to protect the generator from sand-caused damages.


  • Automatically shut the engine down in case of abnormalities in oil pressure, water temperature, and when the Fan belt breaks.
  • Protective covers are attached on all output terminals to prevent electric shocks.
