YAMAHA Inverter EF4500iSE

The EF4500iSE was designed for maximum fuel efficiency and minimum noise, qualities which make it the ultimate RV accessory.

Housing 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. The slow engine speed translates into reduced fuel consumption as well as less noise, vibration and engine wear.

Features:

Whisper quiet operation at 58~60 decibels

With a maximum output of 4500 watts and a continuous output of 4000 watts the EF4500iS is just what you need for running an RV 15,000 BTU air conditioner and 1000 watt microwave oven, or two other major RV appliances simultaneously.

Up to 7.4 hours running time at full rated load between refuelling. Pulse Width Modulation Inverter System produces a sine wave as clean as or cleaner than household electricity making the EF4500iS suitable for computers, televisions, satellite TV systems and other sensitive electronic equipment and appliances.

Optional remote control enables start and stop of the generator from a distance.

Electric start serves up effortless turn the key operation.

Automatic choke makes for 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 is easy to read and 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 refuelling interval.

Twin Bar frame design gives better grip capabilities to lift and load the EF4500iS.

The four wheel design allows for greater portability, the parking brake helps ensure it won't roll away!
