From the Manufacturer
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, and that slow engine speed pays off in reduced fuel consumption as well as less noise, vibration and engine wear. It’s got all the features you expect from Yamaha including an optional wireless remote control. 4500 watt maximum output, 4000 watt rated continuous output – Suitable for running an RV 15,000 btu air conditioner and 1000 watt microwave oven.
