2021 Yamaha EF45ISEZ

Maximum Efficiency - Minimum Noise.

The powerful engine allows this inverter to run at very low engine speed, reducing fuel consumption, noise, vibration and wear.

Top Features* The EF4500iSE picks up where our extremely successful EF3000iSEB leaves off, with even more power and fuel efficiency in a quiet, portable package. Designed for maximum fuel efficiency and minimum noise, its super-powerful engine allows it to run at the very low engine speed of just 2600 rpm - 1000 rpm lower than other generators it its class.
* That slow engine speed pays off big time in reduced fuel consumption as well as less noise, vibration, and engine wear. Up to 15.2 hours run time ant 1/4 rated load.
* The EF4500iSE features Noise Block sound reduction system which makes it a very quiet generator for its output. 58-60 decibels.
* 4500 watt maximum output, 4000 watt rated continuous output suitable for running most 15,000 BTU RV air conditioners and 1000 watt microwave oven, or two major RV appliances, simultaneously.
* Electric start makes starting effortless-turn the key to start and power appliances you want and you can add an optional wireless remote control for easier starting.
* Yamaha's Oil Watch Warning System helps prevent engine damage from low oil and provides added peace of mind.

Features* 4500 watt maximum output, 4000 watt rated continuous output —Suitable for running most 15,000 BTU RV air conditioners and 1000 watt microwave oven, or two major RV appliances simultaneously.
* Noise Block sound reduction system — Very quiet 58-60 decibels
* Low speed running — Using the most powerful engine in its class to run at a constant ultra low speed of 2600 rpm to reduce gasoline consumption, extend running time between refueling and reduce noise and engine wear
* Up to 15.2 hours running time at one quarter rated load between refueling
* Pulse Width Modulation Inverter System — Sine wave as clean as or cleaner than household electricity. Suitable for computers, televisions, satellite TV systems and other sensitive electronic equipment and appliances
* Optional wireless remote control — Start and stop the generator from up to 66 feet away
* Electric start — Effortless turn the key to start
* Automatic choke — Easy starting even in cold climates
* Low oil warning system — Shuts the engine off to protect the engine if the oil level drops
* Power meter — Easy to read meter indicates the amount of power being used and the amount that's available
* Hour meter — Displays the amount of running time accumulated to indicate servicing or refueling interval
* Twin bar — Aids in lifting and loading. Also utilize for transport and anti-theft security
