Features to Consider Before Buying

Perhaps it’s your first time buying a 7500 watt generator, or you’re unsure of the ones we have selected for your consideration. Whatever the case, you should have the necessary knowledge required to understand what you’re buying. So here’s what you need to keep in mind before buying a 7500 watt model.

Power Output

When we say “power output,” we’re referring to both the rated power and maximum output (also called surge power), not just the total power wattage of the generator you’ve chosen to buy. So let’s see what each one means.

Output Power

First off, when your generator has enough fuel, the rated power is the wattage your generator is capable of producing continuously and steadily. Since you’re going for a generator with 7500 watts of rated power, it means you won’t be able to exceed 7500 watts when using it to power the electronics in your home.

Next comes maximum power output, which is important to consider when the machine is being used to power motorized appliances.

Some examples of motorized appliances are refrigerators and air conditioners. These appliances use “surge power,” or start-up power, which is a measurement of the power they require when you turn them on.

The above information should be calculated accurately to find the total wattage required by the appliances your generator will be powering. Otherwise, you may be met with frustration when the machine gives up on you.

Runtime

This word is pretty self-explanatory: the runtime of a generator is a measurement of how long the machine can run on a single fuel supply. Also, the runtime of a generator is dependent upon two main things: the fuel tank capacity and how well the device’s engine is able to perform.

So how do you measure a generator’s runtime? First, consider its half-load. The half-load of the machine refers to when the generator is running at half of its rated wattage.

Depending on the quality of your unit, the runtime can vary. Generally, the best rated 7500 watt generators will be able to give you a runtime of up to 16 hours; however, this number can be as low as 5.5 to 8 hours.

Engine

Generator Engine

You don’t have to be an expert in matters relating to generators to know that the build and quality of the engine on your chosen 7500 watt generator will directly impact its performance, and that too to a considerable extent.

Now, the whole point of an engine is to produce electric energy converted from fuel—look into how well the generator’s engine can do this. And keep in mind that the efficiency of the engine is usually directly proportional to its size.

Whatever you do, make it a priority to select a machine with a well-designed engine meant to optimize fuel efficiency.

Inverter Generator

Inverter Generator

While we’re still on the topic of engines, let’s discuss inverter generators. Although they are new to the market, they are much more efficient, thanks to a smarter and more complex engine mechanism.

So, how does an inverter generator work? By converting AC current into DC voltage, then again into AC voltage. What you get is a motor that utilizes fuel more efficiently while producing far lower levels of noise. Plus, these ones tend to weigh less, too.

Unfortunately, this better performance usually comes at the cost of a higher price.

Fuel Tank Capacity

The 7500 watt options we have looked at today all come with an in-built fuel tank. As with any receptacle, a fuel tank also has a maximum capacity. This maximum capacity has something to do with the generator’s runtime.

To be more specific, a generator’s runtime will be higher the bigger its fuel tank is. Most 7500 watt machines come with fuel tanks with 6 to 7 gallons of capacity.

Portability

Portibility

Now, this is a feature that isn’t entirely important to many people. However, there are several benefits to owning a portable machine. Undoubtedly, most manufacturers of 7500 watt generators on the market won’t prioritize portability, but then there are many who will.

As a general rule, the portability of a model is determined by its size and weight, and also whether or not it comes with wheels to enhance mobility.

So ask yourself whether you really need a portable generator. Take into consideration the machine’s intended purpose. If it’s only meant for occasional use, then you can probably skip buying a portable one.

On the other hand, some people like having the option to bring their generator along on outdoor trips or BBQs. In such cases, having a machine with wheels or a carrying handle can make all the difference.

Noise Level

Generator Noise

The fact of the matter is that generators can be pretty noisy, with some being entirely too noisy to handle. For example, There’s no point in using a model to power up your outdoor BBQ if everyone’s being deafened by the sound it’s producing. And if you live in a trailer park or campsite, this is particularly true. Powerstuffs.com has a Noise Meter to understand noise quality by examples.

However, the good news is that a large portion of generators these days are equipped with noise cancellation technology; even if they’re not, many modern engines are designed to make as little noise as possible when operating. Generally, though, you might have to pay extra for a generator that makes less noise.

Outlets

The number of appliances you can hook up to your generator will be determined by the number of outlets on its body. As it happens, the number of outlets on generators is one that varies a lot, ranging from 2 to 6 to 10. Now, it’s not absolutely necessary to buy a generator with a large number of outlets.

You always have the option to make use of power strips or multi-plug adapters; however, note that doing so sometimes means risking the stability of the electricity flow. The build quality of the engine will have a lot to do with this as well.

Additional Features

What is the best 7500 watt generator? The answer to that question, for many, is determined not only by the most important features of a generator but also the additional features included with it.

And the following factors can make all the difference between a high-performing generator and one that lets you down. Note that many of the following features will tend to hike up the price of the generator.

Automatic Start / Automatic Shut-off

A machine that is able to detect when it needs to turn itself on or off without active participation by you is one that, for obvious reasons, appeals to many people.

This does not only mean that your generator will be able to start supplying substitute power the minute it goes out. It can also work as a crucial safety feature because the automatic shut-off feature of a model depends on its ability to detect too-high levels of carbon monoxide gas accumulation.

If this feature sounds like it’ll make a difference for you, stay on the lookout for generators that come with CO shut-off. Also note the following certifications: ANSI/UL2201 and ANSI/PGMA G300. Alternatively, a machine that produces low amounts of CO in the first place is also a good buy.

Fuel Gauge

A fuel gauge will keep you informed about when it’s necessary to refuel, so as to avoid any unpleasant surprises. It’s unsurprising that, for a lot of people, it’s inconceivable to buy a generator that doesn’t come with this feature.

Alternative/Dual Fuel Capability

The majority of generators, no matter their capacity, are programmed to run only on gasoline. On the other hand, some are made to accept natural gas and propane as fuel as well, with the help of a converting mechanism. Such a feature can do away with a number of fuel-related inconveniences.

Frequently Asked Questions

Q: What can I power with my 7500-watt generator?

A: Many things! Most notably, your 7500 watt model will allow you to power the most important appliances, e.g., your refrigerator, oven, heater, or thermostat. Remember to make wattage calculations first, however.
