Buyer’s Guide

Type of Generator

Which type of generator are you planning to buy? Either you want to buy an inverter machine or a conventional generator?

Inverter generators provide clean power, whereas most of the traditional units fail to give clean output power.

Inverter generators are parallel capable that allow other units to get linked to produce more power. On the other hand, a single conventional generator can generate more power than two inverter generators.

Also, most conventional generators are inexpensive than inverter units. But most of the inverter machines make less noise during operation.

Power

First, determine how much power you need to run your essentials at the home, office, construction site, or campground? If there is a mixture of big and small appliances, then you must select a generator that can give higher output power. And if there are not enough items to run, then you can go for a mid-power or low-power generator.

Make a list of those things that you need to power through your generator, add their watts, and then buy a suitable machine accordingly.

Consider the table below.

AppliancesStarting WattageRunning Wattage
Refrigerator1400300
1/2 HP Furnace2350875
TV400400
Lights300300
AC18001200
Total62503075

The starting wattage is 6250 watts, and the running wattage for all the appliances is 3075 watts. In this situation, you would need almost 3100 watts of power to run all the appliances simultaneously. Don’t worry about the starting load as you can manage this by putting the appliances one by one on the generator. By buying a smaller generator, not only will you save some money on initial purchase cost, maintenance/repair costs are also low for a small generator.

Control Panel

Look for a generator that comes with a well-equipped control panel. On an excellent model, you will find power outlets, plugs, transfer witch, and RV ready options and displays for showing the total running hours, fuel and oil gauge, and wattage drawn from the generator.

Sound Rating

Generators do produce a sound that can make you feel uncomfortable. Therefore, it is necessary to select a unit that can keep you relaxed all the time.

Inverter generators operate quietly, so it is best to go with these units. But if you need a powerful gas generator, then you have to compromise on the noise level.

Still, many companies are adding sound-dampening features to keep the sound level on the lower side. Also, you can keep the machine away from you, if possible, to hear as less noise as possible.

Gas Tank Size

Gas inverter generators come with small fuel tanks, but they give the best runtime because of their fuel-efficient engines. So, the size of the tank only matters when you go for a conventional unit.

Paralleling Ability

Paralleling generators mean connecting two generators to get more output and manage machines with heavy running/starting wattages. Paralleling conventional generators is difficult. For inverter generators, it is a simple task of just connecting two cables. Look for inverters that have the paralleling feature.

Safety

You should also focus on the safety features of your generator.

Low-oil shutdown sensors and overload protection are the two common safety features. Where the low-oil sensor turns off the engine when the generator’s oil goes down, on the other hand, overload protection is responsible for protecting your equipment from high spikes in voltage.

There are also other safety features that are good to have. These include a fuel shutoff feature and spark arrestor.

Ease of Transport

No matter whether your generator is compact or a big sized unit, it must be easy to transport.

When selecting an inverter unit, make sure its carrying handles are comfortable. And at the time of selecting a big conventional unit, ensure it has big, durable wheels and convenient handles.

Power Outlets

You should also focus on the power outlets of your generator. Make sure the power outlets available can power those things that you want to run through your generator.

Warranty and Certifications

Look for a generator that comes with a warranty and certifications. Such features enhance the value of your generator and help save the repair costs after buying a generator.

Price

A high-end gasoline model will be costly as compared to a basic model. Inverters are usually costlier compared to conventional generators but have more features and produce clean electricity. Conventional generators are a little cheap but don’t have the luxury of clean electricity and paralleling mode. We suggest you spend a little extra and go for a generator with all the latest features.

Gas vs. Propane vs. Diesel Generators

In terms of efficiency, gas generators are ahead of propane generators and behind diesel generators. Gas burns slower than propane and faster than diesel in large generators. You would need to keep the load at half to get an optimum running time. Gasoline is more flammable than diesel but has a lower energy rating. Its energy rating is far better than propane/natural gas. A gas generator makes less noise than a diesel generator, and its noise can be reduced with the help of a generator enclosure/high-quality mufflers. The exhaust produced by gasoline generators is not clean as compared to propane but better than diesel generators.

FAQ

What are the benefits of a gas-powered generator?

Gas-powered generators are easy to use. They have been around for quite a time now and are the go-to option of millions of fellow Americans. Gas is readily available throughout the year unless there is an infrastructural breakdown due to a natural disaster. You can store gas for up to a year for such times. Gas tanks are also easy to carry for smaller generators, hence making them highly portable. Understanding a gasoline generator’s engine and other parts is easy compared to a propane/diesel/solar generator.

Do I need a transfer switch with a gas generator?

Yes. You must connect a generator to your home with a transfer switch. Skipping it can cause electrocution, damage to your appliances or generator. If you are using extensions with a generator, make sure you buy a high-quality extension.

What is meant by unleaded gasoline? Is it different from regular gasoline?

No, there is no difference between regular gasoline and unleaded gasoline. You can easily purchase regular gasoline or unleaded gasoline from the gas station.

How can you find out the power rating of appliances to select the best gas generator accordingly?

It is necessary to know how to find out the power rating of appliances to make sure how powerful your generator must be to run all of your appliances.

If the power consumption is not mentioned on your machines or only the current rating (amps) is mentioned, then keep this formula in mind.

Watts = Voltage x Ampere

But before using this formula, make sure the appliances you are going to power run on 120V or 240V.

Is it necessary to do the regular maintenance of a gas-powered generator?

Generators do require regular maintenance. If you do not do that, your generator may become useless very early.

So, it is necessary to check the oil regularly, you can find the best generator oils here. Store your generator in a safe place when not in use. Also, if there is a fuel shutoff option, then never forget to run your generator from time to time without gasoline to prevent stale gas issues.

What are the drawbacks of a gas generator?

Gas has a short shelf life as compared to diesel and propane. It will go stale after 11-12 months of storage. The fuel is also highly flammable, and there is always the risk of spillage and fire when working with gas. Gas generators are no doubt cheaper than propane generators, but they have a high running cost. When gas is burnt in a generator, the exhaust is not environmentally friendly.

Final Words

Buying and selecting a gas-powered generator has now been made easy for you. You can select any of the above-mentioned generators and forget the tension of staying in blackout ever again.
