Honda EM4500CXS Generator Details

The Honda EM 4500CXS petrol generator offers the user a high output generator with a long running time. Featuring a large 23.5 litre fuel tank, running on unleaded petrol, this model will provide 4000 watts of power for 6.8 hours before requiring a re-fill. These professional generators produce a clean electricity output that can be used for a wide range of sensitive electrical applications, including construction, hospitality, emergency and home back up.

The new Intelligent Auto Voltage Regulator (i-AVR) Technology offer electric stability comparable to an inverter generator. This unique technology with i-GX engine technology produces a very stable output and load matching performance ideal for applications with high start up loads and sensitive equipment.

Perfect, reliable generator for home back-up.


  • Electric start for reliable and easy starting.
  • "Intelligent" Automatic Voltage Regulator ensures constant voltage output regardless of the load, ideal for powering sensitive electronics.
  • Oil alert prevents engine damage by automatically shutting the unit down if the oil drops below a safe operating level.
  • Long run time with large 23.5 litre fuel tank and AutoThrottle.
  • Multiple outlets with circuit breakers avoid equipment damage and injury in the event of a short circuit.
  • Switchable voltage between 115V and 230V to run almost any commercial equipment simultaneously.
  • Low noise design - noise reducing muffler to reduce operational noise.
  • A fuel gauge is fitted to help monitor the generator without the need to switch it off.

As per Honda's recommendation we are one Honda Dealers that ensure that their NEW Honda Generators are tested ( PDI ) before dispatch. We remove the NEW generator from the box and start & test, this gives you the confidence that you should not experience any problems when receiving your order.
