Yamaha EF2000iSv2 •
POWER-PACKED, QUIET AND LIGHTWEIGHT
Quietly powers a wider range of applications for an extended time, while still portable and retro-cool.
LIGHT WEIGHT: Easy transport
COMPACT: 2.2 cu.ft. size is easy to store and transport
TWIN TECH (PARALLEL GENERATOR OPERATION): The EF2000iSv2 can be operated in parallel to deliver 25 AMPs of rated power.
PARALLEL GENERATOR OPERATION: The EF2000iSv2 may be connected in parallel with an earlier model Yamaha EF2000iS.* *A second Yamaha EF2000iSv2 is recommended to use the full capabilities of this model.
CONTROLLER WITH ADVANCED PROGRAMMING: The addition of the programming allows the EF2000iSv2 the ability to power a much wider range of applications than previous generation EF2000iS.
SMART THROTTLE VARIES ENGINE SPEED BASED ON LOAD: Improves fuel economy and reduces noise. Runs up to 10.5 hours at ¼ rated load on a tank of gas.
GASOLINE PETCOCK: lets you shut off the gas to run the carb dry for storage and helps prevent stale gas problems.
FUEL GAUGE: See fuel gauge at-a-glance
INVERTER SYSTEM WITH PULSE WIDTH MODULATION (PWM) CONTROL: Produces a pure sine wave to run products with built-in microcomputers or microcomputer-controlled electric tools
OHV ENGINE WITH CAST IRON CYLINDER LINER: Efficient, reliable, powerful providing long life and excellent heat dissipation
OHV ENGINE: Includes steel camshaft and valve train components
OIL WATCH WARNING SYSTEM: Prevents engine damage caused by low oil, avoiding costly repairs and minimizing down time, adding customer confidence and peace of mind
AUTO-DECOMPRESSION SYSTEM: Reduces compression for easier starting
COMFORTABLE GRIP HANDLE: Easy portability and storage
ELECTRICAL OVERLOAD BREAKER: Prevents generator damage in case of overload
CENTRALIZED CONTROLS: Easy access to controls
DC OUTLET: 8A 12V outlet for charging batteries (cables included)
RUBBER VIBRATION ISOLATION FEET: Absorbing feet for smooth operation and noise reduction
50 State Legal
The EF2000iSv2 incorporates a completely controller with advanced programming resulting in improved output characteristics between 1600w-2000w operation ranges. The addition of the programming allows the EF2000iSv2 the ability to power a much wider range of applications than previous generation EF2000iS.
If you need extra power the EF2000iSv2 has you covered a convenient parallel function lets you connect two generators to deliver 25 AMPs of rated power.
The EF2000iSv2 is powerful, portable and retro-modern and delivers maximum output with minimum effort. It weighs a mere 44 pounds, making it easy to transport. Super Light weight for 2000 watts.
The EF2000iSv2 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).
It is very compact (2.2 cu.ft.) which makes it easy to store and transport.
LONG RUN TIME: The EF2000iSv2 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 10.5 hours at ¼ rated load on a tank of gas.
Gasoline petcock lets you shut off the gas to run the carb dry for storage and helps prevent stale gas problems.
Fuel gauge allows fuel level to be seen at-a-glance.
The Yamaha EF2000iSv2 Inverter generator supplies clean, high quality power. The EF2000iSV2 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.
