Description

The Yamaha EF1000iS inverter generator is the ultimate in lightweight portable electricity that is quiet, durable and convenient.A petrol powered inverter generator, the EF1000iS is the lightest generator in its class at only 12.7kg and will run continuously for up to 12 hours without refuelling (at 1/4 load with Eco On). The Yamaha EF1000iS meets the strong demand from the market for a light, portable generator, which offers long continuous running capability and supplies high quality energy required nowadays to power electronic products with built-in micro-computers, such as laptops.

This small but hardworking unit is perfect for camping, fishing, boating, the caravan, motorhome and RV, and will run all your sensitive electronic equipment and accessories such as laptops / tablets, video gaming systems, phones, TVs, coffee maker, portable fan, microwave oven (up to 650 watts), slow cooker, stereo/radio or lighting. The EF1000iS weighs only 12.7kg and is equipped with a new 4-stroke OHV 50cc engine. The Yamaha exclusive double coil system gives better fuel economy, a continuous running time of 12 hours and less noise. Designed to supply commercial-equivalent power, the EF1000iS is compact and combines a convenient carry handle making it extremely portable. Noise Block, acoustically designed sound reduction system helps to make the EF1000iS the quietest portable generator in its class.

The EF1000iS - with its inverter system - features Pulse Width Modulation (PWM) so Voltage stability is within ± 1%, and Frequency stability is ± 0.1 HZ. Its pure sine wave is as clean or cleaner than commercial power, improving the efficiency and versatility of your electronic equipment and accessories compared to other portable power. The EF1000iS… lightweight, powerful, clean and quiet. A powerhouse performer at your fingertips. This super light and super quiet unit comes with many great features, and is also available with a dust cover as an optional extra.

Please Note: This Yamaha generator does not come with oil required to operate it. We are unfortunately unable to ship this online due to it being dangerous goods, but it can be easily found in your local hardware/auto parts store.

More about the Yamaha EF1000iS Silent Inverter Generator:

Newly designed exterior and compact, lightweight, inverter unit reduces weight to 12.7kgs: Lightest weight generator in its class.

Inverter system with Pulse Width Modulation (PWM) control: Industry leading system produces higher-quality and cleaner electricity. Results in pure sine wave as clean or cleaner than commercial power and can operate products with built-in microcomputers.

Noise Block acoustically designed sound reduction system: Moulded casing, noise-absorbing glass wool construction and a newly designed muffler produce unbeatable noise reduction.

Long Run Time: Runs continuously for up to 12 hours without refueling (at 1/4 load with "Economy Control" function on).

Smart Throttle: Load sensing throttle control. Automatically adjusts engine speed to precisely match load, resulting in greater fuel efficiency and noise reduction.

12 Volt DC Output (Battery Charging Cables Included): Recharge 12 volt batteries for RV, auto, marine, aircraft.

Exclusive Dual Coil Alternator Stator: Lower engine speed. Reduced noise, fuel consumption and engine wear.

Centralised Control Panel: Control panel enables easy access to controls.

Fuel Petcock: Reduces carburettor contamination by turning off petrol flow and allowing the carburettor to run dry.

OHV 50cc Engine (overhead valve): Provides improved efficiency, increased reliability, low oil consumption and noise-reducing operation.

Large Fuel Fill Access: Wide mouth fuel fill reduces spilling and overflow during refueling.

Peace of mind with full support: 48 month Manufacturer's Warranty (for personal or recreational purposes)

 

 

What is an Inverter System?
An inverter system stabilizes the amount of voltage and frequency produced by a petrol engine driven alternator through the supply of "sine wave" electricity, with a distortion ratio of less than 3%. That's why Yamaha Inverters are the ideal power source when using precision equipment or micro-computer controlled electrical appliances.


More Controlled, Clean Power
Yamaha's Inverter system produces AC current within a controlled electrical circuit process, known as PWM (Pulse Width Modulation).  As a result, fluctuations in engine speed do not affect the voltage or frequency of the electrical output while at the same time reducing output emissions.


Multi-Polar Alternator System
The adoption of a multi-polar alternator enables the generation of more efficient, high frequency 3-phase AC current that the inverter than turns into single phase.  The high efficiency alternators on a Yamaha Inverter achieve a much lighter and more compact generating unit than conventional 2-pole rotor type alternators.


Smart Throttle
Yamaha's Smart throttle feature automatically adjusts the engine speed to precisely match the energy load.  this means much quieter, more efficient engines that run and last longer.


Unbeatable Noise Block
Yamaha's Noise Block feature, an acoustically engineered sound reduction system , utilises various sound absorbing materials, moulded cases, an intake silencer, fibreglass insulation, plus newly designed mufflers and fans to provide virtually silent running while maintaining the highest quality performance.


Quiet Muffler & Low Oil Shut-off
At the heart of every generator is a strong Yamaha engine that delivers powerful and consistent performance, that's so quiet you'll forget its running.  Every generator includes an approved spark arrestor and a low oil shut-off system for long life and added peace of mind.

Hi, I was very disappointed that it came with no oil in it or with it to be able to put in to use immediately? Where can I buy the correct oil so as I don't void my warranty, or is there an alternative oil I can use, as I am rural and don't have a Yamaha store near by?

Tentworld Tentworld ResponseHi! Sorry, it was at one point standard for any new engine sold off the shelf to require oil. However, as time goes on this is less common and many come with starter packs of oil. We have taken this feedback on board and we are now careful to mention our Yamaha listings do not include oil. To make this harder, our couriers will not permit us to ship oil without charging significantly more for the oil shipment (more than the cost of the oil!). The good news is that the oil that the Yamaha EF1000 needs is very common, it's SAW10W-30 you should find it at your local hardware/petrol station/auto store.
