Q: I have a customer running propane on a Yamaha genset. While burning propane the engine burns excessive oil, not a problem on gasoline. Any ideas?
by Shane Bland from Florida on June 24, 2014

A: The Yamaha portable generators are engineered and warranted to operate on gasoline only. The reason your customer is burning through oil is due to the excessive temperatures of the unit.

Gasoline burns at 485 degrees F whereas propane burns at 1008 degrees F which will cause excessive heat within the engine in turn burning off the engine oil.


by Mike, Product Expert
Q: Can two of these be connected together? I need 3500 watts minimum to start my A/C unit.


by Jeff from California on October 16, 2013

A: Thanks for your inquiry.

The Yamaha High Current model is not compatible with parallel cables. We do offer the EF2000iS Parallel kit which will give you 4000 watts surge and 3200 watts running when using the 30-amp outlet. Below is a link to this kit.

A: You will find the oil recommendations on page 24 of the owner's manual....

Recommended Engine Oil:
A. YAMALUBE 4 (10W-40),
SAE 10W-30 or 10W-40

Q: What is a inverter generator?
by Francine Breland from New Jersey on December 28, 2012

A: An inverter generator is a power generator that can process raw power into a power feed similar to the power received through power lines. The generator part of an inverter generator is usually powered by gasoline or diesel fuel. "Inverter" means that the power is converted from direct current (DC) into alternating current (AC).

Typically inverter generators are much smaller then standard open frame style generators and tend to operate at very low noise levels. This makes them perfect for tailgating or camping and in some cases able to power one or two items in your home in an emergency.

by Mike, Product Expert
Q: Can we use the EF2400iSHC with an RV that only has a 30 amp or a 50 amp plug in?

by Mary Irish from Wisconsin on June 24, 2012

A: This model is too small for 50A output and in come cases it can be too small for 30A output.

This model is capable of producing 17A with a little surge capacity beyond that. It does have the capability of starting "Most" 13.5 BTU RV AC units when using a 20A power cord connected to a 30A RV connection with an adapter.

The EU3000ISEB is a better choice for output capacity and comfort due to its boost capacity and overall running capability.

Q: Is there a way to shut off the gas supply so I can run the carborator dry?
by Bill Garrett from Florida on June 24, 2012

A: Yes, all the Yamaha generators have a fuel valve shutoff allowing you to run the carb dry.

by Mike, Product Expert
Q: How does the EF2400ISHC run a 13,500 BTU air conditioners without a 30amp plungin?
by Larry Mitchell from Texas on June 15, 2012

A: You need to us a 20A cord that matches the 120V - 20A outlet to pull the maximum out of the generator.

by Mike, Product Expert
Q: Are there any good quality inverter generators with electronic ignition in the 3kw range or less?
by Rob from North Carolina on April 30, 2011

A: The Honda EU3000isA and the 2 Yamaha 2800 watt generators are electric start. Click the links below for additional info:

Small Inverter Generators

by Mike, Product Expert
Q: Will an inverter type generator be the right choice for running a sump pump that cuts in frequently? The pump is a 1/3 hp 9amp 115 volt. I currently have a 2500 watt porter cable (traditional) generator with Honda motor. I am looking at a Honda or Yamaha as a backup/replacement. I am unsure if I the EF2400 would be powerful enough for the regular and frequent start-ups.
by Geoff Winsor on January 20, 2011

A: The best thing to do is to calculate the starting amperage of the pump to find out what you need exactly. The formula to calculate wattage is - Starting Amps x Volts = Watts. Then you can determine the size that would suit your needs without purchasing something that may or may not work.

Electric Generators Direct Recommended

The 2000 watt high-current inverter generator from Yamaha is specifically designed to start stubborn, high surge electric motors such as those found on rooftop air conditioners. Until now, a person typically had to resort to a more expensive 3,000 watt inverter generator to muscle through this start-up load. Yamaha claims the new EF2400iSHC will successfully start and run most 13,500 BTU air units.

In addition to its brute starting strength, the EF2400iSHC features an economy mode for... more

Great Mid-power Alternative
Was looking for a single portable jenny that could handle duties in our Outback trailer...our 1500 watt microwave coupled with anything else turned on was too much for a borrowed Honda 2000 unit. I could have bought two of the Hondas and done the cable to get apprx 3000 watts, but that is apprx $2200 retail. For $2000 retail you could get the Honda 3000 unit, but it is 130 lbs, requiring two humans to maneuver it.

Not Up To Task
I purchased this product specifically because it was supposedly able to absorb the "start-up" loads associated with the "high capacity" needs of certain equipment. (hence the HC in the model number). While the unit does a wonderful job powering up my 28 foot trailer, it will NOT run the AC. Not even with ALL OTHER items de-powered. I trusted the many reviews that said it WOULD power up a standard 13,500 BTU RV AC. It won't. It's rated 16.7 amp output is NOT up to the task.
Mike, the Portable Generator Expert
Product Expert
Dennis,
Dennis,
Sorry to hear that it wasn't up to task for your application. You many want to try contacting the AC manufacturer for more information or someone that has HVAC experience.

If you are unhappy with the product, I recommend calling Yamaha directly at (800) 962-7926. They may be able to provide more insight.

Just Ran It 4-days Non-stop
My wife uses an oxygen concentrator. We bought this unit to run the concentrator and A/C on our camper trailer. This past week we camped for 4 nights and ran the unit continuously (with the exception of refueling). Great unit, quiet. The campers in each side of us noted how quiet it ran and said it caused them no issue, even with it running all night long.

This unit starts and runs the Air Conditioning just fine. The weather was cool enough that we did not need to run the A/C ... so... more

Update To Previous Review - Now I'm 100% Happy
Bought a $12 capacitor off of Amazon, AC unit starts right up and the generator hardly seems like it's having to work to keep it running and barely revved up at all to kick it over. A reliable, well made capacitor might be a good add on item to offer customers that are on the fence about whether this will start their 13.5k BTU AC unit. Took about 10 minutes to install it up on the roof under the AC unit cover.

Apparently the main reason this thing doesn't kick over all 13.5k AC units is... more

This Is It
I just bought the 2400 it is fantastic!!! I have a off grid cabin with no chance of electric. I had looked at going solar however I needed to power a 5000 btu window unit, solar seemed to be too massive to afford or install. I have used a 2000 watt Honda before and it struggled to run the cycles of the window unit. The Yamaha 2400 did the trick with power to spare. Not as light as any 2000 watt however still manageable for one person. It started first pull I was not expecting that and hit my... more

Great Generator
Added gas and oil and it started right up. Delivered promptly and was in perfect condition on arrival. This is my first generator, bought to run small appliances during power outages. Not as easy as it should be to figure out what it will run and won't run but that's my problem, not the generators. Would have bought a larger Generac but can't in my state (Ca). On the pricey side but very happy with the purchase.

Great Product, No Complaints.
I purchased this generator from a local Yamaha dealer ship in Lemoore, CA around 2006. This generator sits for months at a time. I turn the gas off and let the carb run dry. When I need to use it , I just turn the gas on pull the choke and pull it one time and it starts flawlessly every time.

I have a 23 foot toy hauler with a 13000 BTU AC and a microwave and this generator will run either one (not both at the same time)The Onan generator in the trailer is pretty noisy. I run the Yamaha at... more

Very Satisfied
Very satisfied with my purchase. Electric Generators Direct shipped fast to my home. The Yamaha 2400 runs my camper trailer's air conditioner and runs the convection oven. No need to run (2) two 2000 generators in parallel. Weighs 75 pounds which I can carry but has two handles so even less weight to carry than a 2000 generator with two people!

I bought this to power my 5th wheel, but not power my 15,000 BTU A/C. I have tried to run the A/C and it will not do it. Other than that, it is a great generator, and it is super quiet.

Brandon,
Please check out some of the other reviews and how easily the problem was solved. Consider a hard start/capacitor kit, which is very inexpensive and will allow your generator to start your AC.

Worked Like A Charm
We used this new generator for 2 weeks on a "dry camping" hunting situation. It stared easily - even the wife had no problem starting it. It ran quietly while the demand was low and answered the call quickly when required to give more power.
We haven't tried running our 13.5K A/C yet, but are confident that it will perform as advertised.
