The Yamaha EF2200iS Inverter Generator boasts a rugged design with a powerful high output Yamaha MZ80 engine. It supplies clean, high power output featuring Pulse Width Modulation (PWM) with its inverter system. The Tri-Handle Design makes loading, unloading, and moving the unit a breeze and is designed for two people to easily move the unit. Starting and stopping the unit is simple with the Yamaha Smart Dial Knob. With a sophisticated muffler for quiet operation, Yamaha Quiet Technology allows you to have a conversation near the generator and may not even realize it’s running. Smart Throttle, a load sensing rpm control, allows greater fuel efficiency and noise reduction by automatically adjusting engine speeds to match the load. It will run up to 10.5 hours at ¼ rated load on a tank of gas. In the event of a power overload, the Overload Power Reset feature enables the device to restore power without shutting the unit down by holding down the reset button for up to three seconds. The LED Illuminated Control Panel makes it easy to check the status of your generator both day and night. The control panel features a multi-function display as well as an illumination light that cascades over the entire control face of the unit for easier low light operation. It was built with the RV camper in mind, incorporating a standard RV outlet as a standard plug meaning no more searching for the right adapter to power your RV. A regulated DC socket outlet is integrated into the control panel allowing more devices to easily connect to the generator. The Fuel Gauge allows the fuel level to be seen at-a-glance. The Yamaha Easy Carburetor Drain allows you to empty the fuel from the carburetor to help prevent stale fuel problems and prepare the unit for long term storage. A convenient tool-free maintenance panel allows you to access critical engine components for easy service of your unit. The Twin Tech Parallel Function allows you to connect two EF2200iS generators in-line with a Twin Tech Cable for rated 30 Amps of rated power.
