Q: CAN I TETHER A YAMAHA 2400 WITH A 2000 YAMAHA IN ORDER TO GAIN WATTAGE, OR DO THE TWO YAMAHA GENERATORS NEED TO BE IDENTICAL. by DOUG MACKEY from Texas on June 27, 2016
A: Thank you for your inquiry.
The 2400 Yamaha does not have parallel capabilities and cannot be connected to any other inverter. The EF2000i and all other models have to be paralleled to a identical unit. by Jared, Product Expert
Q: can this unit run a few lights and heater in my rv tr.at night by Gloria Jernigan from New Mexico on June 25, 2016
A: Thanks for your inquiry.
Generator sizing is based on the starting amperage of the equipment you plan on powering which will determine the size generator needed.
Proper sizing of the generator is based on 80% of the generators running capacity, so when a large load kicks in the unit has enough flexibility to handle it and still provide clean voltage output.
To calculate the wattage, the following formula will help convert starting amps to watts - Starting Amps x Volts = Watts
You will have to check with the manufacturer of the heater and TV to get the starting and running watts in order to know of this generator will be able to power it.You may have to manage the loads when using a portable generator.

2016 Yamaha Ef2000isv2 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.

Expensive, Hard To Start
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.

"Had the product I needed at a competitive price and shipped it on time."
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!
Pros:Reliable, Easy To Use, Light Weight, Easy To Store
Cons:Bad Instructions

Powers My Travel Trailer!
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.

Worked Out Great
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.

Yamaha's Versital Units
Purchased two Yamaha EF 2000iSV2 generators and a parallel kit so I would get 3200 watts and 30 amps of 120 volt power. These units are sweet. The Yamaha's are quiet, smooth running, efficient, well built, and easy to start. At this time it's the coolest set up I have seen. Works perfect.
