The Yamaha EF1000iS offers you performance along with excellent mobility. The EF1000iS features an excellent inverter system that provides high powered output – delivering strong efficient power of nearly 1,000 watts. Although the EF1000iS gives you half the wattage of the EF2000iS model, it compensates by providing you with up to 12 hours of non-stop power on a single tank of fuel (while running in “Economy” mode). Mostly everything else on this machine is virtually identical to the 2000-watt model.
Like the EF2000iS model, the Yamaha EF1000iS also features specially built technology which maximizes fuel efficiently. The excellent inverter system is the centerpiece of its design. The gas powered inverter was precision designed to yield clean, high quality electricity. It generates its energy in sine waves, providing the most clean and efficient energy that your money can buy. In other words, you will have excellent power for all types of machinery while not having to ponder about polluting the air with power generated from “unclean” energy. The Yamaha EF1000iS also features a special breaker for overload which will save the machine from damage in the unlikely and unfortunate case an overload should occur. Additionally, the EF1000iS has a very heat efficient OHV engine, ensuring long life of the generator. Another key feature of the Yamaha EF1000iS is the “Smart Throttle Load” setting which auto-sets the speed of the engine relative to the output level, resulting in better fuel efficiency. The EF1000iS also features a dual coil alternator stator. With this feature, engine speed can be reduced thereby reducing fuel use.
The light-weight design of the Yamaha EF1000iS generator is made so that you can take it anywhere, weighing only 28 pounds. The control panel of the EF1000iS is centrally located, making it a cinch for you to have complete access to all the generator’s nifty features. The EF1000iS is also capable of recharging 12 volt batteries and has a DC output which serves this specific purpose. It’s great for recharging RV’s or boats.
