Yamaha EF2000iSv2 - 1600 Watt Inverter Generator

The EF2000iSv2 is a lightweight, fuel-efficient and versatile portable generator featuring a NEW controller with advanced programming that can power a wide range of equipment in the field.

Designed and engineered to bring quiet, durable power to the outdoors, the new EF2000iSv2's increased versatility and 2000 watts of power can easily handle higher load application like hair dryers, microwaves, tire warmers, heaters and much more. And at only 44 pounds, the lightweight generator is a mobile and efficient power source that will run for up to 10.5 hours on a single gallon of gas.

The EF2000iSv2 is a great option for recreational and small utility use - and by combining two units, you can increase your power for larger jobs. Yamaha's Twin Tech capability allows two EF2000iSv2 units to be connected in parallel to provide up to 30 amps of power and run air conditioners and larger appliances in a trailer, hunting cabin or around the house during a power outage. The parallel function allows two EF2000iSv2 generators to parallel and compatible with the prior EF2000iS model.

While power is the priority, the EF2000iSv2 inverter is also fitted with Yamaha's most technologically sophisticated muffler with a USFS-approved spark arrestor, a Smart Throttle and Noise Block technology producing excellent noise reduction at 51.5 - 61 dBA - 1/4 rated to rated load. Yamaha designed this inverter to be so quiet that it is easy to have a conversation nearby without realizing it is running.

The EF2000iSv2 includes many features not available on competitive units, including a standard fuel gauge, an auto-warm up feature that helps cold starting and an independent fuel petcock, which allows users to shut off the gas to run the carburetor dry preventing stale gas problems and costly carburetor cleaning and repair.

Yamaha's leading line of generators comes standard with 3 - year factory warranty and offers the same high quality engineering and technology that goes into all Yamaha's ATVs, motorcycles, and outboard motors.

After considering a less expensive brand and model, I was convinced to buy the Yamaha as the "gold standard" in quality and reliability. The first time I started and tested it was fine. Then when we got to our campsite the next day, it was a complete pain to start. Must have pulled the cord way more than fifty times to get it started the next two times we needed it. Frustrating.

I have two in tandem running power for my camper. Works great and my wife hooked ihem up and started the generators with one pull. Nice! Also it was amazing how quick the generators got to my house after I ordered them. Within two days! Nice work.

This exceeded all expectations. It is super quiet! Easy to manage and light. We love this product. So glad we chose this over the Honda. More features and less money...great value.

Went dry camping this week in a new trailer. I charged the dual batteries and ran an electric strip to charge phones and other devices. Starts first pull and was very quiet. I plug a battery charger into the outlet and it’s a good idea. I can set the amps sent and run it on full auto. The charging system and cables included are adequate, but dedicated chargers are cheap and offer more versatility. The unit sips fuel in this mode and worked really well. People in surrounding campsites said they did not hear it until they were right up on it. I choose this over Honda because of the fuel gauge and fuel shut off. I ran the carburetors empty of fuel before storage.

Very happy with the product. Runs everything we expect it to. It is as advertised.

A better buy than its competitors. Fuel gauge is nice but hard to read! Like the fuel cut off from the tank. Seems like a good product! Seems a bit louder than its competition!

Just used my 2000IS and was I glad I had it! Worked flawlessly and lasted 10+ hours on a tank of fuel. Neighbor could not believe how quiet it was. Used it continuously for 4 days without a hitch! Thank you guys for recommending this unit to. Ordered another for my kids.

Got the generator to go with another EF2000is for my trailer while camping, worked great.

Very quiet.

Love this generator, econ mode is very quiet. The only thing I don't care for is the fuel gauge is hard to see. Had to mark the case with an e.....f mark to see clearly what fuel remains. Otherwise...awesome.
