Yamaha EF2000isV2 Inverter Generator (2000W)

  • $ 899.00

Need a portable generator for your RV? The Yamaha EF2000isV2 Inverter Generator (2000W) is a powerful, portable inverter generator that can deliver up to 2000W maximum power, or 1600W of continuous clean, high quality power. The EF2000iSV2's inverter uses Pulse Width Modulation (PWM), so voltage stability is within ± 1%, and frequency stability is ± 0.1 HZ. Its pure sine wave is as clean as or cleaner than utility power. If you need extra power,  the EF2000iSv2 has you covered: a convenient parallel function lets you connect two generators to deliver 25 amps of rated power. 

Weighing a mere 44 pounds, this compact (2.2 cu.ft.) generator is easy to transport and store. For RV use, you'll need the RV Adapter Kit (sold separately), which includes a 30A receptacle.

The EF2000iSv2 is also fitted with Yamaha’s most technologically sophisticated muffler. It’s so quiet that you can have a conversation near one and may not realize it is running (51.5-61 dBA @ ¼ to full rated load). Part of this is the Smart Throttle feature, which senses the load and and automatically adjusts engine speed to match, ensuring optimum fuel efficiency and quiet operation. This generator will run up to 10.5 hours at ¼ rated load on a tank of gas.

And will it last, you ask? Yes, it will - Yamaha generators have the longest emission engine durability ratings issued by the Environmental Protection Agency and the California Air Resources Board.
