Yamaha EF2000iS

Yamaha EF2000iS

Big power in a compact package.

Get power at your fingertips, whether you need to run a cooker or commercial power tools. The EF2000iS is one of the lightest generators around, and its 21 kg weight means you can carry it with just one hand.

Despite its power, a large capacity muffler ensures that it runs with a low noise emission of just 51.5 dB(A).* The compact control panel, with all dials on one side, makes it easy to use, and fits with the new clean and retro overall design. The 4.2 litre fuel tank will allow for 10.5 hours of continuous operation at 1/4 rated load. So, whether you take it camping or to a building site, this brushless inverter is up to the job.

Inverter system with Pulse Width Modulation

This industry-leading system produces high-quality, clean electricity. Its pure sine wave is as clean or cleaner than commercial power, making it suitable for products with built in microcomputers.

Smart Throttle™ load-sensing throttle control

This intelligent system automatically adjusts engine speed to precisely match load - resulting in greater fuel efficiency and noise reduction.

Oil warning system

To prevent engine damage and costly repairs, and enhance long-term durability, the generator automatically shuts off when oil begins to run low. It cannot be re-started until oil is added.

TwinTech™ capability

Connect two EF2000iS’s for 3600 watts of maximum power (requires accessory cable available at extra cost).
