Buyer’s Guide

Generator Type

Before going to select your ideal 7500-watt generator, decide whether you need an inverter generator or a conventional generator.

Inverter generators produce clean power, but they are expensive. Also, they generate less power but are more fuel-efficient. Here, take an example of Honda EU7000is that produces 7000 watts of peak power and 5500 watts of running power having a 5.1-gallon tank that offers 18 hours of runtime at 25% load.

On the other hand, conventional generators generate more power and are cheaper than inverter generators, but they don’t provide clean and stable power and are less fuel-efficient.

Single vs. Dual Fuel

It is also important to decide whether to go with a single fuel or a dual fuel generator. If you don’t have a high budget, a single fuel unit is best for you because dual fuel generators are expensive to buy.

But a dual fuel generator offers fuel selection. When you run out of gas, you can easily switch to propane without delay.


Not only you need a powerful engine, but it also must be reliable and fuel-efficient. A cast iron sleeve with powder-coated finish keeps the engine protected from unwanted weather conditions. So, make sure that there is extra protection for your engine. Also, it is essential to keep your engine clean to increase its life.

Moreover, an air-cooled engine is better than a liquid-cooled engine so check this thing as well.

Fuel Tank Size and Runtime

Some 7500-watt generators come with medium-sized fuel tanks whereas some units feature large fuel tanks. So, it all depends on your needs. If you are buying a generator for a construction site, then a generator with a large fuel tank is necessary so that you can work day and night. But if you are buying a generator for your home then a 6-gallon tank with 8 to 9 hours of runtime is enough. During this time, you can easily take your good night’s sleep.

Noise Level

It is always recommended to buy a noise-free or less noisy generator for your home usage. You should also keep your neighbors in mind before selecting a 7500-watt generator.

Inverter generators produce less noise as compared to conventional generators, but not all conventional ones are considered as noisy. So, in order to spend your day and nights peacefully, buy a generator with a lower decibel rating.

Power Outlets

You should also look at the control panel of your selected generator to know how many and what type of outlets are available. A 12V DC outlet is necessary along with 120V and 120/240V outlets.

Starting System

We all know that recoil start systems need a human effort. As the generator gets old, it becomes hard to start the generator in one or two pulls. So, it is suggested to go for a generator that features an electric start system with a recoil backup.

Some of the units also come with a remote control start system through which one can quickly turn the generator on and off from quite a distance.
