L I G H T W E I G H T It's not uncommon to have generators weighing over 120 lbs. And weight usually corresponds to power output. That is, until Yamaha created the EF2800i. Tipping the scales at just 64 lbs., it's the lightest generator in its class. The key is its multipole rotor with a small stator and Pulse Width Modulation inverter. This design is smaller and lighter than a conventional two-pole alternator and large stator — and it makes the EF2800i extremely portable.
C L E A N O U T P U TMost generators can't power anything with microcomputers or sophisticated electronics — their generated power has too many spikes and irregular wavelengths that can destroy sensitive equipment. The EF2800i — with its inverter system — features Pulse Width Modulation (PWM) so wavelength distortion is less than 2.5 percent — it's ideal for equipment that requires stable frequency and voltage.
