Best Portable Propane Generators For Home Use

June 7, 2023

The most commonly-used standby generators are the gas-powered generators. This is because they are more affordable and cost-effective. Yet, some users find the use of propane generators more sensible. But why? Well, there are many succinct reasons for this. First, the maintenance cost of a propane generator is less. Plus, it is environmental-friendly than those of gas- or diesel-powered generators. Moreover, propane allows for a longer time of storage without degradation in its quality.

There are many factors you have to consider when buying a portable generator, but the primary factor that you must consider is the fuel type that the generator would use to produce electricity. There are many types of fuel in use to power portable generators such as diesel, gasoline, solar energy, and propane. Many, however, prefer propane over any other type of fuel, and choosing propane is undoubtedly a wise decision.

What is Propane Generator & How It Works?

Most homeowners nowadays have backup or standby generators. This is to ensure that their homes will never run out of power once there is a power outage. Their homes are also equipped with automatic transfer switches that command the standby generators to start. This switch likewise allows the transfer of electrical load to the standby generators. This ensures that there is power for the essential appliances within their households during a power interruption. Standby generators generally run on the following fuels—diesel, natural gas, or liquid propane gas. 

Portable generators may vary according to the fuel that powers them; yet, although they are powered by different fuel, their structures and features are basically the same. The propane generators, for example, basically have the same design and structure; but the main difference is that they have highly specialized carburetors (instead of the traditional carburetors) that are specifically designed to burn propane. Every propane generator must have the converted carburetor installed to run on propane.

Propane is basically a limitless fuel, for this reason, it is ideal for use as a fuel for portable generators. Moreover, it does not require you to pour fuel into the holding tank. Instead, you merely need to connect the propane generator to the propane tank hose. Propane is a highly flammable hydrocarbon gas that can power an internal combustion engine. As it burns and powers the engine, it eventually produces electricity.

Benefits of Using Propane Generator

Easy To Cold Start

Portable generators usually come in handy when there is a power outage. Hence, many generators stay unused throughout the year. They become usefully relevant only when there is a power outage. Liquid propane is one of those fuels that have infinite shelf life if they are properly stored as compared to the gasoline which tends to go stale when not used after a year. For this reason, you can be very sure that your propane generator will have ready fuel that could power the internal combustion engine of your generator even if your generator has not been in use for several months or years. You don’t need to worry about cold starting your seldom-used propane generator because propane generator is surely easy to cold start.

Cleaner Fuel & No Gum Deposits on Carburetor

Moreover, unlike the gasoline generator that generates much gum deposits on the carburetors, propane generators do not. The gum deposits generally become a problem for generators that are not frequently used. On the other hand, propane is a very clean fuel, and it burns cleanly and doesn’t leave gum deposits. As such, it is very easy to cold start even after not being used for several months. 

Cleaner & Non-Toxic Emissions

Another succinct advantage that the propane generator has over other types of generators is its clean fuel. It burns cleanly, and its byproduct is non-toxic. Moreover, it doesn’t produce much emissions as compared to other types of fuels. Since it doesn’t diminish in its quality when stored, it is undoubtedly ideal for seldom-used generators. Additionally, the propane generators are very quiet when operating; hence, it is suitable for use during camping and other occasions wherein there is a need for the emergency backup energy source.

Important Factors to Consider When Buying a Propane Generator

1) Your Power Usages & Needs

First, you need to Consider Your Power Needs. Generators like propane generators are rated by kilowatts, and this kilowatt rate usually indicates the power output of the generators. Hence, if you are shopping around for a generator, you need to figure out beforehand which electronic gadgets and appliances you are going to run using the portable generator.

One of the electrical equipment that really eats up much power is the HVAC. Hence, if you are going to choose a generator and you want to power your HVAC using that generator, you need to select a propane generator model that could easily power your HVAC.

To determine your power need, you need to check or examine the data plate on your air conditioning. This data plate will reveal the size in tons or BTUs of your HVAC. Each capacity in ton is equivalent to 12,000 BTUs. Hence, if the data plate says 3 Ton unit, it is equivalent to 36,000 BTUs which requires an 11-kW generator. Make sure that your propane generator is powerful enough to run your HVAC, especially, during a power outage when you badly need to make your HVAC to function.

2) Starting Mechanism

Propane generators either feature a pull-to-start option or a push-to-start button. If your model is an electric start or push-to-start button, chances are, you will need a battery to start your generator. The need for a battery is surely an additional cost. Most electric generators that have push-to-start button do not come with a battery.

Some generators likewise sport an auto turn-off feature. This feature enables the generators to automatically shut off when the oil level of the engine is very low. This feature is indeed very useful if you intend to buy a propane powered generator. Some generators are designed to start when the power goes off automatically. This is a great feature that you should also consider because more often if the power goes off, your house will be shrouded in darkness with the lights not working. If your generator automatically starts when the power goes off, you would not be required to start the generator when the power goes off personally.

3) Storage Space

Propane generators, just like most generators, are bulky enough and may require spacious storage space. For this reason, you would surely need to figure out at the onset the size of the generator that you intend to buy so that you can prepare the space where you are going to store it. As a good advice, you need to store your generator near an electrical outlet. Moreover, you need to follow the proper ways of storing the generator and comply with the electrical, local, noise codes in your town or city.

4) Noise Level when Operated

One factor that you should strictly consider when buying a generator is the noise level it creates. The maximum decibel of noise that an operating generator can produce is up to 80 decibels which is tantamount to noise generated by a continuously running loud lawnmower. You can easily imagine how your neighbor will react to your noisy lawn mower if the noise of your generator is equivalent to the noise level of a typical lawn mower. 

Generators that are designed for house use are generally less noisy. The majority of the rate at 62 decibels from 25 feet away. One caveat, however, when buying a generator is to check out the ratings of the manufacturer and the reviews about the generator model. You can surely glean enough information from these two sources.

5) Transfer Switch

Generators generally need a transfer switch that allows them to readily spring into action when needed during a power outage. This automatic transfer switch can readily detect if the power fails. It also automatically disconnects the power from the line and transfer the source of power from this line to the generator. This automatic switch transfer readily energizes your home by connecting your power grid to the generator. 

Since the transfer switch is very much essential to the automatic functioning of your generator, you need to carefully choose the right transfer switch according to your generator’s needs. At the onset, it is good to understand and figure out the electrical service panel’s amperage. Check out the main breaker of your electrical panel to find the amperage. Most homes have a 200-amp main breaker. This implies that most households can consume up to 200 amps. Some old homes, however, consume less power and for this reason, it would be good to figure out beforehand your home panel amperage to align it with the transfer switch amperage.

6) Available Outlets

Most propane generators come with a minimum of four electrical outlets. Hence, if you intend to buy a propane generator, it would be good to consider the number of outlets in its design and the number of appliances that you would like to connect to your generator.

7) Economy Setting Feature

You would surely want your power generator to be fuel efficient as much as possible. Hence, it would be best if you chose a power generator that has an electrical throttle or economy mode feature. This feature enables your generator to decrease fuel consumption when you don’t need maximum power from your generator.

8) Safety Features

Another good factor to look at when buying a propane generator is the safety features of the generator. These safety features are valuable to avoid accidents and other untoward incidents due to the use of your generator. The more safety features the generator has, the better the choice it would be.

9) Hidden Operational Costs

If you are not cognizant of the necessary steps on how to hook your generator to the fuel source, it would be wise to avail of the service of a local utility technician to do this job. The service fee for this technician will add up to the cost of buying and maintaining a generator. Hence, you should consider this additional cost, especially, if you are on a budget. Propane generator may cost you up to $10,000, and if you haven’t studied the abovementioned additional cost, you may be surprised in the end with the total cost once you have already bought the generator and want to use it.
