Things to Consider
Now that we have talked about eight different generators, it is time to develop a base to determine which one meets your requirements. Every family has a specific set of needs, and this buying guide will help you prioritize them and match you with the perfect 7,500-watt generator. Let’s get started!
A 7500-watt generator: What can it power?
7,500 watts sounds like a small amount of energy to power up a house, but it is more than enough and is considered to be one of the best whole house generator options. The best thing about a 7,500-watt generator is that it isn’t too big, compact in size, affordable, and portable. You can take it with you on camping trips or power your RV using the generator.
It can cover all the essentials like keeping your house warm during the winters and cool during the summers. It can help you cook food and avoid it from getting spoiled. If you use well water to flush toilets, the generator will power that as well.
The generator can fuel a water heater, refrigerator, freezer, lights, air conditioner, microwave and oven along with delicate appliances like hair dryer, toaster, and coffee maker, but if you need even a more powerful model our advice is to check out the 10,000-Watt generators, on the contrary, if you rather search for something less powerful, then we’d advise you to look at 6,500-Watt generators.
Important features to consider while choosing a 7500-watt generator
Any 7,500-watt generator you want should have certain features that make it efficient and durable. It should meet your requirements and legal regulations, so you don’t have to go through the trouble of replacing it with another model later. Here are nine important features you should consider while buying a 7,500-watt generator:
You can choose between conventional and inverter generators, which are quieter than the former. You can change the load and turn down the noise further. However, they are more expensive. A good example of a powerful inverter generator on this list is the Honda EU7000iS.
There’s one more choice you have to make – single fuel and dual fuel. As expected, dual fuel generators are usually more expensive, but they are a preferred choice because some models allow you to switch between fuels. An exception here is the Pulsar PG7750B, which is more than fairly priced for a dual-fuel model.
A dual-fuel generator is more convenient when you are in the middle of a storm, and the fuel you use isn’t available. You can use the second one and keep electricity flowing into your house.
Rated and maximum power output
The higher the maximum power output, the more appliances and tools your generator can start simultaneously. Remember that some tools and appliances have much starting wattage much higher than running. However, buying a generator with a high rated and maximum power output won’t be of any use if it has a short runtime.
Look for a generator with not only powerful, but a reliable and fuel-efficient engine. It must be protected from extreme weather conditions with stainless steel or powder coated cast iron sleeve. The engine is the core of your generator, so clean it regularly even when not in use.
Fuel tank capacity and runtime
The logic is simple – buy a generator that runs the longest by using the least amount of fuel. Ideally, it should have a runtime of nine hours, so you can sleep throughout the night without having to wake up at dawn to refill the tank. The Honda EU7000iS has a runtime of 18 hours at 25 percent load and consumes only 5.1 gallons of fuel. Pulsar PG7750B is another wonderful model with 13-hour runtime at 50 percent load and consumes 6.6 gallons of fuel.
We live in a modern era, so there’s no need to pull a recoil system and hurt our backs while starting the generator. All models mentioned on our list have an electric start with a recoil backup. The Westinghouse WGen7500 even comes with remote control, so you don’t even need to touch the generator to switch it on.
The lower the noise level, the more peaceful you and your family will sleep during the night. The most silent generator on our list is the Honda EU7000iS. It produces only 52 dB(A) of noise at 25 percent load. It sounds similar to two people whispering with each other. If you don’t have too many appliances to run, this generator by Honda is an amazing choice. It is expensive but will last you for an entire lifetime. If you are interested in buying another model, stick to generators that make no more than 75 dB(A) of noise. You might also want to check Sportsman generators to find quieter models.
Size, weight, and portability
If you’re going to use your generator only occasionally to power your house during an outage, portability probably won’t make the top of your list of important generator features. However, if you’re going to take your generator with you on a trip, power your RV etc., the size and weight are a thing to consider.
Warranty is crucial because especially if you stay in a state or area frequented by storms and power outage. If some problem occurs, the brand technicians will come and repair it. Before a storm or hurricane, ask the technicians to give it service, so you are all prepared for any natural disturbances.
Conventional generators are the traditional type of generators with a motor that usually runs at 3600 rpm. It produces a standard current of 120 Volts AC @ 60 Hertz, which is required by appliances in the United States. The generator uses typical fuel source like gasoline, propane, or diesel.
On the other hand, inverter generators are relatively new to the market and are known as 3-phase generators. They have an AC output, which then is converted to DC and converted back to AC. Thus, the energy is cleaner and successfully delivered in a single phase, called the pure sine wave.
The major difference between the two is the type of applications they are suitable for. If you use a conventional generator to charge phones and laptops, you will damage the battery. You will need an inverter for them. However, if you want to power up an entire motorhome, the good old conventional generator is your best bet. Another difference is their weight. Inverters are compact, lightweight, and portable.
Since conventional generators run at 3600 rpm, they tend to consume less amount of fuel and last at least 40 percent longer than inverters. At the same time, inverter generators are quieter because their engine is close to the ground, have special mufflers, and fitted with sound-dampening technology.
The fuel you choose depends on your needs. However, propane is one of the cleanest fuels and offers better benefits. If your local store that sells propane is shut, you can always go to the gas pump to buy the fuel. It is readily available and has a long shelf life. Propane is a clean fuel, so cleaning the generator is easier as compared to the best diesel generator and gasoline generator. Propane tanks have safety valves, so you are less likely to spill and waste the fuel.
It isn’t temperature sensitive, which means it won’t become viscous in the winters and thin in the summers. Also, the fuel is very similar to natural gas when it comes to performance. In fact, it produces 2,490 BTUs per cubic foot, making it double as efficient as natural gas.
One simple way to power both 220V and 110V appliances and tools simultaneously is by using a 220/110 Volts transformer. It is an affordable accessory, which is fitted with a universal brushed motor that stays unaffected by changes in the Hz mains frequency.
Our top pick out of the eight generators we reviewed in this article is Westinghouse WGen7500 because it meets every single requirement that we mentioned in the buying guide. The best rated 7500-watt generator runs for 11 hours at 50 percent when you fill the 6.6-gallon fuel tank. The generator produces 7,500 running watts, which is more than the other seven generators on the list.
Another feature that won us over was its three years long manufacturer’s warranty and free lifetime support. It has four outlets, which are sufficient to run four major appliances at once. The generator is a great choice for a household that goes camping often. Since it is portable, you can pull it around with least efforts.
Also, it is CARB, EPA, and CSA compliant, which means you can use it in California. The only downside of this product is that it is a bit loud and runs at 73 dB(A). You can always add mufflers to reduce the noise, so your family enjoys a peaceful sleep throughout the night.
