Yamaha EF2400iSHC Inverter Generators Review
Having a proper inverter is important if you plan to spend time away from the city and exploring with your RV. While it’s fun to imagine ‘getting away from it all’, things can get uncomfortable when you can’t rely on electricity.
I would like to have an inverter like the Yamaha EF2400iSHC when I need my mobile phone but the battery was dead and I was hours from a campground with electricity!
Let’s take a look at this inverter and why you should have it in your RV.

Inverters are used to power all the appliances that you take with you in your RV – lights, fans, the RV’s refrigerator, TVs and DVD players. They also come in handy when you need to charge your phone or laptop battery.
Although most RVs come with inverters these days, yours may not have one or you could be looking for a replacement. The Yamaha EF2400iSHC is a reliable inverter from a trusted brand. It boasts a large fuel tank and longer running times than most of its competition.
This will matter a lot when you’re enjoying mother nature and there’s no other electricity source.
RV enthusiasts who don’t plan to spend time away from areas with electricity might feel that they don’t need an inverter. But, should the worst happen and the power go out, an inverter will feel like a lifesaver.
Rather safe than sorry, right?
When investing in an inverter, it’s essential that you keep in mind how much power you want. If you want to have backup power simply for charging phones and powering low-energy LED bulbs, you don’t need a beast.
However, if you’d like to have enough juice for a TV, electronics and more, an inverter generators with the power that the Yamaha EF2400iSHC has will be most valuable.
There are other factors that are important as well. How long the fuel will last is of importance so you know what to expect. The noise level is also something to consider because you might have to leave your inverter on for hours at a time.
The Yamaha EF2400iSHC comes from a line of other powerful inverters such as the EF2200iS. When compared, though, this inverter is more competent and operates at a lower noise level.
It also has a smart throttle feature, light and compact design and 1.6 gallon tank that keeps it running for 8+ hours.
Features & Benefits
Here’s a quick look at the features and benefits of the inverter so you know what you’ll be getting from it performance-wise.
Ease of Use
The Yamaha EF2400iSHC has proven to be an uncomplicated inverter, which is something that people who just want to enjoy time in their RV (like me!) appreciate. It’s easy to start up thanks to the startup panel which can be found in the front.
There are 3 LEDs on the panel that will notify you if anything is wrong.
The fuel gauge comes in useful when you need to check the inverter’s fuel levels. You don’t even have to open anything up to make sure you’ve got enough fuel for the task at hand.
This power electronic device has 2 400 starting watts and 2 000 running watts, so it can handle just about everything you may need to power.
It provides cleaner power than commercial methods and the engine speed can be adjusted to match what you need it to do.
According to Yamaha, the inverter is capable of powering the majority of 13,500 BTU RV air conditioners. It is also promised that the inverter can handle convection ovens, microwaves and hairdryers.
This is usually the first thing that people concerned about when consider buying an RV power electronic device
. Fortunately, Yamaha keeps in mind about their customers and make this one with lower noise levels than many other similar inverters.
On average, most inverters operate at about 68 to 80 decibels at a distance of 23 feet. The Yamaha EF2400iSHC operates at 53 to 60 decibels at the same distance. Of course, the noise is affected by the load you put on the inverter so the more things you power, the louder it will be.
Another feature of this powered inverter that I really like is the Smart Throttle system. Yamaha is known for adding it to their products and it’s incredibly useful.
The system is what adjusts the inverter’s engine speed to work with the load that it needs to power. This helps to improve fuel-efficiency and lowers the noise levels.
The inverter features a 1.6 gallon fuel tank which is much bigger than most similar power providers of its kind.
Pulse Width Modulation
Although the inverter already boasts minimal Total Harmonic Distortion, Yamaha was not satisfied. They went even further and equipped it with Pulse Width Modulation. This means it can provide even cleaner electricity.
Thanks to this feature, the inverter is one of the safest choices for your devices and electronics.
Because the Yamaha EF2400iSHC is made with an aluminum die cast frame and cast iron cylinder liner, it’ s very sturdy.
The strong materials mean the inverter will last a long time and enjoy many seasons with you in the great outdoors.
Although it’s not the lightest inverter on the market, it is still not a heavy thing to lug around. At 75 pounds when empty, a healthy person will easily be able to carry it around because of the convenient placement of the handles.
After a lot of research we purchased this Yamaha EF2400iSHC generator from Amazon in 2015 mainly for home back up in case of power outage. Generator was delivered in decent shape without any damage. Added Mobil 10-40 oil and fresh gas (Sta-Bil Marine added) and it started with just one pull. Much quieter than non-inverter generator. We have it to power fridge, microwave, plasma TV, router, fish tank, sump pump, furnace blower without any hiccups.
When running at 1500W and above (i.e. full size microwave and hair drier at high mode) the engine will rev at higher speed but the noise is bearable. Open it up the inside shows very high quality parts and clever designs for maintenance.
Like Honda EU2000i this Yamaha’s carburetor can be easily drained after use. One design that is different than legendary Honda 2000i is that Yamaha has separate fuel shut-off valve, which allows user to run the engine till the fuel line is dry. It does not have fuel pump as Honda’s and it make it slightly easier for long term storage preparation (Honda needs additional step to disconnect spark plug and pull 3-4 times to squeeze out the gas from fuel pump).
On the other hand, I wish it has Honda’s captive screw design on service panel. I do like the fuel gage on Yamaha, which is easy to use. It weighed around 80 lbs with fuel and make it more difficult to move around than Honda 2000i.
It worked great on camp site but the weight / size is no match to Honda 2000i. We have used it several times and every time it took just one or two pulls to start and no issues. For storage I took extra steps to siphon the gas from tank, drain the carburetor and keep the unit in dry and clean area.
Overall we are very pleased with the quality and dependability of this generator. If weight / portability are priorities, Honda 2000i is better. If higher power is preferred / less concerns for weight and size, then Yamaha 2400. Both are excellent quality, design, built and low noise levels. You cannot go wrong with either. I would recommend the OEM cover that fits well on this generator.
If you feel this inverter just doesn’t cut it for you, there are 3 alternatives you can think about.
As a sibling of the Yamaha EF2400iSHC, this inverter performs just as well. It offers 1 600 watts from a 1.1 gallon tank and has lower noise levels. It also promises to run for 10 hours, which is better than the 8 hours of the EF2400iSHC.
I went around and around trying to decide what portable generator to purchase as a home backup. I’m one of those individuals who believe you get what you pay for, so I decided on the Yamaha ES2200si which is close to double the cost of the off brand units.
I will say this generator is quality inside and out and I like the fact it has a 3 year warranty and replacement parts are readily available at any local Yamaha dealer if needed down the road. I’ve had the unit about 1 month and have run it through it’s break in period using the recommended 10W30 oil.
The generator is easy to start and is very quiet. I checked the decibel level using a decimeter phone app and it’s in the 57 dB voice range at 25ft. All the controls are nicely arranged and work well, plus having a 30 amp outlet makes it a snap to plug into a home inlet box. The auto idle feature works perfectly and the output is a steady 1800 watts and handles surges on appliances well. I tried it with a 1400 watt space heater and a 500 watt halogen lamp at the same time and the generator just purred on! The LED wattage load gauge is very useful plus it does double duty as an hourmeter.
One concern that as also mentioned in another review is The muffler pipe not being centered out of the rear hole. I’m concerned over time the plastic may melt or deform from the heat. I did check the temperature and it seems ok, but I tried to center the engine by loosening the motor mounts, but there is no room for adjustment. It just seems odd because the rest of the unit’s fit and finish is excellent. Don’t get me wrong, this is still probably one of the best portable generators on the market, but with minor improvement it could be even better. Would I buy it again? Absolutely!
UPDATE 01/27/20 – After studying the exhaust opening, I realized what Yamaha was trying to do by off-setting the the pipe thru the hole. The spark arrestor can be removed for cleaning by loosening the clamp without removing the rear panel. I just had to loosen the clamp and rotate it 90 degrees. All is good!
FYI, don’t fall for the unverified negative reviews, the generator is not underpowered as engine displacement does not correlate to hp and torque. Also, theare is a reason the Yamaha weighs 5-7 lbs more that it’s competition, it’s built sturdier!
Major ice storm hits upstate NY.
Well the Yamaha was really put to the test. Without power for 30 hrs and counting. So far I’ve run the generator powering lights, a microwave oven, a refrigerator, a laptop, a ceramic space heater and the internet modem and the Yamaha never once went into overload protection. This thing is incredible. And to boot only used 1 gallon of gas every 10 hours. I’m so happy I chose this generator. I know I’d be skeptical of this review, but it’s all true.
This is a powerful inverter that is able to give you wattage power of 2 800 from a 3.5 gallon tank. However, it won’t perform as quietly as the Yamaha EF2400iSHC.
The Generac isn’ t as powerful as the Yamaha EF2400iSHC, so if you’ re looking for something smaller, this might be the right one for you.
It has a 1.2 gallon tank and puts out 1 700 wattage. It’s also a lot lighter at only 46 pounds. Yet, it promises to run for more than 10 hours, making it a real workhorse.
I was skeptical about buying this brand since I have a Honda 2200 inverter as well that I really like, but I needed a 2nd one and Honda is double the price as this one.
This does come with oil and a funnel for putting the oil in the motor since it is shipped dry. One thing to keep in mind that the overload light comes on for about a minute when you first start it which is normal operation. I bought this as insurance when if the power goes out since we get a lot of storms here and I live out in a rural area. DO NOT RUN ETHANOL GAS in this or any small engine!
Lots of reviews on generators in general of sitting with gas and not starting weeks later. Ethanol gas gums up the carburetor if it sits too long. I run non-ethanol premium gas in all my equipment.
Because of the amount power of startup on appliances, this would run one big freezer or a big frig, or a small chest freezer and a frig. Mine I run a big freezer, some led lights, router and a laptop. The 2nd Honda 2200 watt I run another small freezer and a big frig. It is actually cheaper to buy 2 of these then a 4,000 watt inverter generator. I have one that runs the upstairs and the 2nd one runs out of the walkout basement.
I love how quiet it is and eco switch which runs at a lower power.
As you can see, the Generac is smaller and less powerful than the Honda and the Yamaha. But it puts out less wattage as well. The Yamaha is not as powerful as the Honda and doesn’ t have as big as tank either. However, its noise levels are much lower.
|Table Header||Yamaha EF2200iS||Honda EB2800IA||Generac 7117|

The Yamaha EF2400iSHC is a powerful but quiet inverter that will give you power anytime you need during your RV travels. You will be able to keep all your devices charged, watch some TV and even use a microwave to avoid cold dinners.
This inverter can run for 8 hours, doesn’t need a worrying amount of fuel and is safe for your devices. Overall, it is the perfect RV companion that will enhance your experience away from home.
Beyond that, it comes with two key fobs that have an excellent range of 80 feet. Last but not least, you get a lifetime warranty with this product. That sets it apart from the rest of the locks in this category. We feel that it offers an excellent price to performance ratio.
So, if you’re looking for a good combination of security and dependability, this is a wise choice.
Now that you know all about the best choices of RV door locks, it’s your call.
