YAMAHA Inverter Series

     Quiet, clean, and portable. All Yamaha inverters use Pulse Width Modulation (PWM). This means these generators deliver clean power so you can use them confidently for powering computers, solid-state appliances with built-in computer functions or microcomputer-controlled power tools.

 

     Inverters are great for noise sensitive areas and are perfect for camping with a tent, RV, or cabin. With noise levels only reaching as much as 67dBA (as loud as a dishwasher), you won't even know its on!
