With the new EF30iSE generator, Yamaha has introduced the next generation of ULTRA QUIET portable electric generators! This unit has an unbelievable 51dB running sound level as a result of it's silent design, to cut irritating noise. An Economy Control function has been adopted which chooses the minimum engine rpm necessary for the actual electrical load. Here' s how it works: Typically, after starting a generator as it' s generating power the generator operates at a constant rpm to produce peak power. This is usually the loudest noise level. With "Economy Control," the engine speed automatically changes to match power demand. Therefore, if you' re powering only some small appliance or lights, the generator runs at a low engine rpm. Then, as power demand increases, the engine revs up accordingly. What' s more, then combined effect of a compact, lightweight, new-design muffler ad optimum distribution of sound-absorbing material combine to produce exceptionally quiet running.
C O M P A C T B O D YLightweight, Compact Body, and Large Wheels as Stanard Equipment. The combination of the compact engine, a compact, lightweight inverter unit, a compact alternator with multipolar magneto and outstanding electrical output-per-weight ratio and plastic-material covers, etc., help achieve a low overall weight of 67kg / 147 lbs. That is light enough to be carried by two people. Also, for greater ease in moving, the generator is fitted with four wheels.L O N G R U N N I N GThe highly fuel-efficient 4-stroke, OHV, single cam, 175cc engine, the large capacity fuel tank, and the "Economy Control" mode that enables low-rpm running, all combine to achieve a continuous running time of 20.5 hours (at 1/4 capacity load).
C L E A N O U T P U TAn inverter is adopted to rectify the electrical current. This provides Pulse Width Modulation (PWM) control in order to produce high-quality electricity supply. That means you can use this generator with confidence as a power source for appliances with built-in computer functions or microcomputer-controlled power tools.S I N G L E P A N E L C O N T R O L SUnbeatable ease of use is guaranteed by the single control panel that brings together all the controls on one surface, including the AC and DC outlets, the output indicator, the output malfunction lamp, the stop switch, the fuel cock, and the backup recoil starter.
