Features

The EF4500iSE picks up where our extremely successful EF3000iSEB leaves off, with even more power and fuel efficiency in a quiet, portable package. The EF4500iSE is designed for maximum fuel efficiency and minimum noise, qualities which make it the ultimate RV accessory. The most powerful engine in its class allows this inverter to run at the very low engine speed of just 2600 rpm—1000 rpm lower than other generators in its class, and that slow engine speed pays off in reduced fuel consumption as well as less noise, vibration and engine wear. Naturally, it’s got all the features you expect from Yamaha including an optional wireless remote control.
