Yamah EF2000iS Inverter

Product Description


  • Powered by Yamaha's MZ80; 79cc, air-cooled (fan assist), OHV, 2-valve, 4-stroke, single cylinder engine with electronic capacitor discharge (CD) ignition.
  • Auto decompression system reduces engine compression to provide a light recoil starter pull for effortless manual starting.
  • Cast iron cylinder liner provides excellent heat dissipation and extends service life.
  • Pulse Width Modulation provides super "clean" power. As clean or cleaner than you get from a household receptacle.
  • Rated AC output for continuous use is 1,600 watts / 13.3 amps.
  • Bonded neutral
  • Non-fuse type circuit breaker (NFB) prevents internal circuit damage in the event of an over load.
  • Yamaha's Noise Block body design features a moulded casing and noise-absorbing glass wool to provide ultra quiet operation.
  • Smart Throttle / Economy Control automatically adjusts engine speed to match the load, saving fuel, reducing noise and engine wear.
  • Manual choke
  • Auto Warm Up (4 to 6 minutes) ensures consistent power delivery during cold start-ups.
  • Yamaha's Oil Watch Warning System automatically shuts off the engine when oil level is low and will not re-start until oil is added, preventing costly engine damage and enhancing long-term durability.
  • Indicator lights for AC power output, low oil and AC overload.
  • Washable foam air filter reduces maintenance costs
  • 12 Volt DC output and cables for charging RV, auto and marine 12-volt batteries.
  • On-off fuel petcock lets you shut off the gas to run the carb dry for storage, helping to prevent stale fuel problems, which are becoming more common with ethanol based fuels.
  • Large fuel fill hole and sealable vent on gas cap for easy filling and transporting. Fuel gauge is standard
  • Cleanable spark arrestor stops the possibility of sparks from exiting the exhaust.
  • Rubber feet isolate vibration for smoother operation and reduced noise.
  • Suitcase style handle and light weight (21 kg / 46 lb) make the EF2000iS very portable.
