The all-new
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 our biggest 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.
