Generators

• Lightweight, easy to carry design – Compact lightweight alternator reduces weight to 27.9 lb., the lightest in its class.
• Smart ThrottleTM, load sensing RPM control – Greater fuel efficiency and noise reduction by automatically adjusting engine speed to match the load.
• Pulse Width Modulation (PWM) – For clean, high quality power. Voltage stability is within ± 1%, and frequency stability is ± 0.1 HZ. Its pure sine wave is as clean as or cleaner than public utilities power.
• Auto Warm-up – Automatically increases engine speed for 4~6 minutes to ensure smooth power delivery during cold startups.
• 12-volt DC cable is included as standard equipment.
• Exclusive dual coil alternator stator – Greater output at a lower engine speed for reduced noise, fuel consumption, and engine wear.
• Centralized control panel – Easy access to controls.
• Gasoline petcock lets you shut off the gas to run the carb dry for storage – Prevents stale gas problems.
• 50cc Overhead Valve (OHV) engine – Noise-reducing operation with improved efficiency, increased reliability, and low oil consumption.
• Large fuel fill access – Wide mouth fuel fill reduces spilling and overflows during refueling.
• EPA & CARB Emission Engine Durability Rating – Yamaha generators have the longest emission engine durability ratings issued by the Environmental Protection Agency and the California Air Resources Board.

1. Yamaha generators have the longest emission engine durability
   ratings issued by the Environmental Protection Agency and the
   California Air Resources Board.
2.  The EF1000iS weighs in at 27.9 pounds, making it extremely
   portable.
3. Noise Block is Yamaha’s acoustically engineered sound reduction
   system which helps make the EF1000iS among the quietest portable
   generator in its class. (47 dBA to 57 dBA – ¼ rated to rated load).
4. Gasoline petcock lets you shut off the gas to run the carb dry for
   storage and helps prevent stale gas problems.
5.  The EF1000iS features Smart Throttle, a load sensing rpm control
   that allows greater fuel efficiency and noise reduction by automatically
   adjusting engine speed to match the load. It will run up to 12 hours
   at ¼ rated load on a tank of gas.
6.  The Yamaha EF1000iS inverter generator supplies clean, high
   quality power. The EF1000iS – with its inverter system – features
   Pulse Width Modulation (PWM) so voltage stability is within ± 1%,
   and frequency stability is ± 0.1 HZ. Its pure sine wave is as clean as or
   cleaner than public utilities power.
7. The Auto Warm-up feature automatically increases engine speed for
   4~6 minutes to ensure smooth power delivery during cold start ups.
8.  Yamaha’s Oil Watch Warning System helps prevent engine damage
   from low oil and provides added peace of mind..

2. Gasoline petcock lets you shut off the gas to run the carb dry for
   storage and helps prevent stale gas problems.
3. Fuel gauge allows fuel level to be seen at-a-glance.
4.  The EF2000iS is powerful, portable and retro-modern and delivers
   maximum output with minimum effort. It weighs a mere 44 compact
   pounds, making it easy to transport.
5.  The EF2000iS is fitted with Yamaha’s most technologically
   sophisticated muffler. It’s so quiet that you can have a conversation
   near one and may not realize it is running. (51.5 dBA to 61 dBA – ¼
   rated to rated load).
6.  It is very compact (2.2 cu.ft.) which makes it easy to store and
   transport.
7. If you need extra juice, the EF2000iS has you covered—a
   convenient parallel function lets you connect two generators to deliver
   up to 30 maximum amps.
8. Meets even strict California Air Resources Board and Environmental
   Protection Agency standards for low emissions.
9. Yamaha’s Oil Watch Warning System helps prevent engine damage
   from low oil and provides added peace of mind.

3. Fuel gauge allows fuel level to be seen at-a-glance.
4. This model boasts High Current output which is designed
   specifically to increase motor starting capability and to improve air
   conditioner starting. This High Current model starts most high
   efficiency 13,500 btu AC in temperatures up to 110° F.
5. The EF2400iSHC has an aluminum die-cast frame, combined with
   an aluminum TCI rotor and other weight-saving measures to provide a
   powerful and compact generator weighing only 75 pounds.
6. The EF2400iSHC uses Pulse Width Modulation (PWM) to
   produce high-quality electricity comparable to the power supplied by
   public utilities. Use this generator with confidence as a power source
   for microcomputer-controlled appliances and other devices with builtin
   computer functions.
7. Yamaha’s Smart Throttle feature automatically adjusts engine speed
   to match the load. The result is quiet running, maximum fuel
   efficiency, and a run time of 8.6 hours at 1/4-capacity load.
