2025 Yamaha Power Generator Inverter Series EF2000IST
Quiet, durable and convenient, the new Yamaha EF2000iST is designed for anyone seeking an ultra-portable source of electricity. The new "T" version, based on the popular EF2000iS, has the special ability to "twin" two units together. Weighing only 21 kg (46 lbs.) and featuring an extra-large handle for easy transport the EF2000iST is ready to deliver clean, quiet power wherever and whenever you want it.
Features may include:
- Powered by Yamaha's MZ80; 79cc, air-cooled (fan assist), OHV, 2-valve, 4-stroke, single cylinder engine with transistor controlled (TC) ignition.
- Auto decompression system reduces engine compression to provide a light recoil starter pull for effortless manual starting.
- Cast iron cylinder liner provides excellent heat dissipation & extends service life.
- Pulse Width Modulation provides super "clean" power. As clean or cleaner than the power you get from a household receptacle.
- Rated AC output for continuous use is 1,600 watts / 13.3 amps with a single unit.
- When "twinned" with another EF2000iST rated AC output for continuous use is 3,000 watts / 25 amps. (note: requires accessory parallel terminal kit available at extra cost (part number: 7PB-YH579-80-00).
