Yamaha EF6300iS Inverter Generator Electric Start

Sale price$7,395


Yamaha 6.3 kVa, Electric Start Inverter Quiet Generator

The most powerful and most advanced inverter generator ever, the EF6300 quietly and confidently powers high demand items like pumps and caravan air-conditioners, as well as sensitive equipment like LCD LED TV's and computers. It comes with an electric start system and optional wireless remote.


  • Electric Circuit Breaker - Cuts off current when output voltage exceeds the designated maximum output capacity.
  • 4 Stroke OHV Engine - Powerful performance, precise valve actuation, excellent heat dissipation, low fuel consumption and reduced noise level.
  • Oil Warning System - Engine stops automatically when oil level is low, prevents engine damage and minimises costly repairs.
  • Auto Decompressor - Light recoil starting reduces compression for effortles starting.
  • Fuel Guage - Displays fuel level without having to open fuel cap.
  • Voltage Meter - Voltage confirmation at a glance.
  • Petrol Petcock - Reduces carburettor contamination during storage by turning of petrol flow and allowing the carburettor to run dry.
  • Brushless Alternator - Minimal maintenance, hassel-free service and clean output.
  • Electric Starter - Provides effortless starting, electric motor cranks generator until it starts.
  • Spark Arrestor - USFS-Approved - Keeps sparks from exiting exhaust system to reduce risk of errant sparks causing a fire.
  • Noise Block  - An acoustically engineered sound reduction system.

More controlled, clean power

Yamaha's Inverter System produces AC current within a controlled electrical circuit process, known as PWM (Pulse Width Modulation). As a result, fluctuations in engine speed do not affect the voltage or frequency of the electrical output  while at the same time reducing output emissions.

Multi-polar alternator system

The adoption of a Multi-Polar Alternator enables the generation of more efficient, high-frequency, 3-phase AC current that the inverter then turns into single phase electricity. The high efficiency alternators on a Yamaha inverter achieve a much lighter and more compact generating unit than conventional 2-pole rotor type alternators.
