Yamaha’s EF3000iSE/B provides clean high power at low noise levels. There is the EF3000iSE model for those who are looking for a quiet yet powerful generator. However, the EF3000iSEB model is for those who need more. It has boost technology to increase power by using a battery connected to the alternator. This brings the total max AC output to 3000 watts. There is also a 12V 12 amp DC output, which is commonly used to charge batteries.

The EF3000iSE/B is powered by an OHV 171 cc, 5.5 hp engine designed to be durable, offer high output, and to run for lengthy periods of time. And, this generator can do just that with a runtime of 20.5 hours @ ¼ rated load on its 3.4 gallon tank without refueling. In addition to its impressive runtime, it is also very quiet at 51- 57 dBA. This enables it to be used in a variety of settings. Weighing 147.4 pounds, it is not extremely light. However, its well crafted design allows for easy transport.

It comes with an electric start option to add convenience. The inverter system with pulse width modulation control ensures a clean energy output. It has an oil watch system to prevent engine damage. The Noise Block feature significantly reduces the overall loudness during operation.
