If you want to run an air conditioner of 10,000 BTU, 4500 starting power is enough for it. But to run other home appliances simultaneously, you have to turn off your A/C.
THD Rating: THD (Total Harmonic Distortion) determines the distortion present in an electrical signal. Its THD rating is less than 3%, making it an ideal choice to power smartphones, tablets, TV, and other delicate electronics.
Tank Capacity and Runtime: A 4.5-gallon plastic tank allows the generator to run up to 15.2 hours at 25% load.
Eco-Throttle System: With the Eco-throttle System’s help, the generator senses the exact load applied and allows the engine to change its speed to meet that load. It results in fuel efficiency and quieter operation.
Power Receptacles: With two 120 Volt 20 Ampere (5-20R) receptacles, you can power home appliances and power tools. And you can use the 120 Volt 30 Ampere (L5-30R) outlet for connecting your generator with an RV.
Power Meter: It shows how much amount of power is being used and how much is available.
Indicator Lights: Yamaha EF4500iSE includes low-oil, output ready, and overload indicator lights.
The low-oil indicator indicates that the generator runs out of oil, whereas the output ready indicator tells your unit is ready to use. And the overload indicator warns your generator is being overloaded.
Safety: Low-oil shutdown and overload protection are its safety features.
Once the oil level goes down, the engine turns off automatically to avoid costly repairs.
Noise Rating: Its operational sound is 58 dB (A). It is higher than the noise rating of Westinghouse iGen4500.

If you don’t know which of the factors you must consider when buying a Yamaha generator. Then, there is no need to worry. In this buying guide section, we are going to help you by discussing those factors.
Here generator type means either conventional or inverter.
Inverter machines give less power output, but they produce clean power. They convert AC power into DC, and then this DC power is reconverted into clean AC power. They have smaller fuel tanks but fuel-efficient engines that give excellent runtime. Also, they operate without making much sound. However, they are expensive and not made for users having a limited budget.
On the other side, most of the conventional generators don’t produce a pure sine wave, but they give higher output power. They have bigger fuel tanks but not highly fuel-efficient engines. Also, most of their models are louder, but they are quite affordable than inverter generators.
Tank Capacity and Runtime
Always try to buy a fuel-efficient generator with a higher fuel tank capacity. This will help you to get extended runtime. Yamaha EF6300iSDE has a 4.5-gallon fuel tank that offers up to 13 hours of runtime. It is a fuel-efficient generator, and that’s why it gives this excellent runtime. On the other hand, Yamaha EF5500DE has a 6.9-gallon tank, but it offers 13.5 hours runtime because it is not a fuel-efficient machine.
One of the most important factors to consider while selecting a generator is its power output. To make sure that you don’t buy a wrongly sized generator, make a list of all the appliances you need to power during an outage. Mention the starting and running wattage of each appliance and calculate the total. To help you out, we have given an example below.
|Appliances||Starting Wattage||Running Wattage|
If your power needs are somewhat similar to the example given above, you will need 3900 watts to start all the appliances at one time and 2200 watts to keep them running. In such a situation, a generator with 2500 running watts will be perfect. Don’t worry about the high starting wattage requirement; you can accommodate it by starting the motorized appliances one by one. A smaller generator is cheaper to buy and has a low running cost.
Yamaha offers one of the best and advanced control panels in the market. Its generators come loaded with an odometer, on/off buttons, low oil warning lights, power outlets, choke, and other features.
Make sure that the unit you plan to buy has all the power outlets. It will be a hassle to connect extensions every time you run your appliances on the generator. A generator must come with at least two 120V outlets, USB ports for connecting mobile chargers and other sensitive devices, RV plugs, and it must be transfer switch ready.
Eco model or throttle control allows the generator to adjust the engine speed according to the load applied to it. It helps in reducing the running cost of the generator.
Apart from the heavier and powerful units, all Yamaha generators are highly portable. You get heavy-duty wheels and carry handles in smaller units. Yamaha aces the portability features and manufactures lightweight inverters, which are best for outdoor use.
Paralleling your generators mean connecting two same models with each other and increasing the power output. It helps in running heavy machines and also provides you with more power outlets.
All Yamaha generators come with essential safety features. You get surge voltage protection, low oil, and overload shutdown protection. Yamaha strives to make sure that you get a safe working experience with its generators.
Generators do make noise; there is no doubt about that. But some machines create a less operational sound as compared to others. Inverter generators operate at lower decibel ratings than conventional generators. But there are also many portable conventional or home standby generators that don’t make much sound during operation.
In a nutshell, always buy a generator with a lower decibel rating to keep you and your neighbors stress-free.
Warranty and Certifications
Just like the other leading brands, Yamaha also offers warranty and excellent customer service. When you buy a Yamaha generator, you not only get an outstanding generator, you also get excellent after-sale and customer service. All Yamaha models are EPA and CARB compliant. You can use them in all the States without any worries.
Yamaha generators don’t come cheap. You get excellent features, durability, reliability, and excellent customer service. For all such things, you will have to pay more.
