They are commonly used in homes as a portable power station for space heaters, ductless mini splits, or for small appliances. In addition, they work well for construction sites, camping, and other outdoor events.

They can be used to power a sump pump or emergency medical equipment.

Portable Generator Safety

Portable home generators are useful tools to provide backup power during outages, camping trips, or other situations where electrical energy isn’t available. However, their use also comes with potential hazards.

First thing, always operate your home generator outdoors and away from windows, doors, and vents.  This prevents carbon monoxide (CO) from accumulating indoors. CO is a colorless, odorless gas.  If inhaled, carbon monoxide poisoning can lead to death.

Secondly, avoid overloading your generator. It’s crucial to understand the wattage requirements of the devices you plan to power.

Overloading, or requiring too much power, can cause generator failure or fires. Your generator’s manual should provide specific guidelines on safe load levels.

Furthermore, always use the correct type of fuel as recommended by the generator’s manufacturer.

Improper fuel can cause damage to your generator and pose a fire risk. Also, allow your generator to cool down before refueling to prevent any accidental fires.

Lastly, protect your generator from the elements. If it’s raining or snowing, operate the generator under a canopy-like structure, away from water puddles.

The best way to protect yourself and loved ones while using a generator is to follow the manufacturer’s instructions exactly as written.

Do not create an emergency situation during a power outage.

Standby Generators

Standby generators, also known as whole-house generators, are larger, stationary machines that can provide power to your entire home. 

A home backup generator switch on automatically when a power outage occurs.  In the event of a power outage, an automatic transfer switch or manual transfer switch activates the generator.  

In fact, standby diesel generators are commonly used for critical services such as hospitals and telecommunications industry. 

Additionally, they use various fuel types, including natural gas and propane.  While they are more reliable and powerful than portable generators, they are also more expensive.

Inverter Generators

Inverter generators are a type of generator designed for producing high-quality, clean electricity. 

They work by first producing AC power, then converting it to DC power, and then inverting it back to AC power. This process helps to maintain a consistent flow of electricity, minimizing fluctuations and producing a steady, clean, and reliable power source. similar to the power you receive from the electrical power grid. 

Inverter generators are typically more energy-efficient, quieter, and more compact than conventional generators.  This makes them an ideal backup power source for camping, tailgating, and other recreational activities.

They provide clean and stable power, perfect for power tools connected via extension cords and sensitive electronic devices like computers and televisions. 

Inverter generators make for a good option in highly populated areas due to the low noise.  Although they operate more efficiently than traditional generators, they come with a higher price tag.

Solar Generators

Solar generators harness the power of the sun to generate electricity from solar energy. This renewable energy source is eco-friendly, silent, and require minimal maintenance. 

However, their power output may not be sufficient for larger homes or extended emergency power outages, especially during cloudy or rainy days.

They consist of solar panels, a battery, charge controller, and an inverter to produce solar power. The solar panel absorbs sunlight and converts it into electricity. Then, the charge controller regulates the electricity, preventing overcharging or undercharging. 

The electricity is stored in the battery and can be used when required. The inverter converts the stored DC power to AC power, which can be used to run household appliances or charge electronic devices. Solar generators are a sustainable and renewable source of power, ideal for outdoor activities or emergencies.

Factors to Consider When Buying Home Generators for Power Outages

Choosing the right home generator involves considering several factors such as electrical power output, type of fuel, size, portability, and cost.

Power Requirements

First, determine your power requirements. The average home uses around 7,500 watts of power, so a generator producing 9,000 watts would be sufficient for most homes.

However, if you have multiple heavy appliances like air conditioners or refrigerators, you’ll need a generator with a higher power output.

For instance, if you plan to power only essential appliances like refrigerators, heating systems, and lights, a generator with a power output of around 5,000 to 7,500 watts might suffice.

Conversely, you may need a larger generator capable of producing 20,000 watts or more if you plan to power your entire home including air conditioning systems, electric ovens, and more, .

To determine your power requirements, make a list of all the appliances and systems you want to keep running during a power outage. Then, add up their wattage and choose a generator that can supply at least that amount of power.

Remember to consider both running watts (power needed to keep devices running) and starting watts (extra power needed to start devices).

Fuel Source

Next, consider the fuel source. Gasoline, propane, and natural gas are common fuels for generators.

Gasoline generators are usually less expensive but can be challenging to start in cold weather. Propane and natural gas generators are more efficient and easier to start, but they are generally more expensive.

The fuel type for a home generator largely depends on your specific needs and circumstances. However, propane is often considered the best option due to several reasons. 

Propane generators are relatively clean burning, have a long shelf life, and the fuel is widely available. Moreover, they perform well in both high and low temperatures. Natural gas and diesel are also good options, but they might not be as efficient or convenient as propane. 

Dual Fuel Generator

A dual-fuel generator has the ability to run on two different types of fuel.  Typically, these generators use both gasoline and liquid propane. The dual fuel capability offers flexibility and convenience, allowing the user to choose the fuel source that best suits their needs or is readily available.

Remember, safety and proper storage are crucial no matter what fuel source you choose.

Size and Portability

The size and portability of the generator are also important considerations. If you have limited space or need to move the generator around, a compact, portable generator might be a better choice.

Some generators can be quite loud, which could be a problem, especially in residential areas. Look for a generator with a low noise level, or consider investing in a soundproof enclosure.

Home generator noise levels refer to the amount of sound, measured in decibels (dB), produced by a generator during its operation. These levels can vary based on the size, type, and quality of the generator. Smaller, inverter generators often operate at quieter levels, between 50-60 dB, similar to a conversation at home. Larger, industrial generators can produce noise levels of up to 80-90 dB, similar to a lawnmower or a busy highway. It’s important to consider these noise levels when selecting a generator, as excessive noise can be disruptive and potentially harm hearing over time.

Budget

Finally, consider your budget. Generators can range from a few hundred dollars to several thousand. While it might be tempting to go for the cheapest option, remember that you often get what you pay for. Consider investing in a reputable brand that offers good value for money and has positive customer reviews.
