YAMAHA Inverter EF2000iS

The all-new EF2000iS provides a practical, versatile machine that can go anywhere with ease.

This ingenious new inverter is fitted with Yamaha's most technologically advanced and sophisticated muffler. Whisper quiet and compact, the new EF2000iS has enough power to run a microwave oven or a television, making your campsite a much more comfortable place to be.

Lightweight / CompactInverter generators are built with a multi-polar alternator, creating an excellent power to weight ratio. Inverters use fewer parts making them ultra compact and lightweight, so the EF2000iS can go anywhere with ease.

High-Quality ElectricityInverter technology regulates the electrical output using Pulse Width Modulation (PWM). The result is a pure sine wave as clean as or cleaner than commercial power, which allows the operation of sensitive products with built-in microcomputers.

Economy ControlEconomy idle control returns the engine to idle when there is no load, for improved fuel efficiency and quieter operation.

Smart ThrottleAutomatically varies engine speed to precisely match load, resulting in greater fuel efficiency and noise reduction.

4-Stroke OHV Air-Cooled EnginePrecise valve actuation and heavy-duty design offer improved efficiency, increased reliability and quiet operation Cast iron cylinder liningA unique "spiny" cylinder sleeves provides optimal heat dissipation, consistent performance during continuous use and long engine life.

Silent TypeAcoustically designed sound reduction system, with a moulded casing and noise-absorbing glass wool construction to provide very quiet operation of only 51.5 dB.

Auto Decompression SystemAutomatically reduces engine compression to provide a light recoil starter pull for effortless manual starting.

Overload Protection Non-fuse Thermal BreakerProtects AC circuits in case of an overload for added durability and peace of mind

12-Volt DC OutputProvides recharging capacity for 12-volt batteries (charging cables included)

Oil Watch Warning SystemAutomatically shuts off the engine when oil level is low and cannot be re-started until oil is added, preventing engine damage and costly repairs while enhancing long-term durability

 Specially Designed Muffler and Spark ArrestorOffers super quiet operation and keeps sparks from exiting the exhaust system, reducing chance of fires caused by an errant spark

Fuel gaugeAllows the operator to monitor the fuel level without opening the filler cap
