Buying Guide: Inverter Generators

Whether you’re camping, tailgating, or simply need a reliable backup power source, an inverter generator is the perfect solution. These compact, fuel-efficient, and quiet generators provide clean, stable power for all your sensitive electronics. With so many options on the market, how do you choose the best one for your needs? Our comprehensive buying guide will help you navigate the world of inverter generators and make an informed decision.

What To Look For When Selecting an Inverter Generator

Power output and capacity

The inverter generator’s power output and capacity vary from model to model. This value is typically measured in watts and varies depending on the generator’s size and engine. It’s crucial to determine the total wattage of the appliances and devices you plan to power to choose a generator that can handle that load. Keep in mind that some appliances have a higher starting wattage than running wattage, so it’s essential to account for this when making your calculations.

Fuel type and efficiency

Inverter generators are available in different fuel types, including gasoline, propane, and diesel. Each fuel type has its advantages and disadvantages in terms of availability, cost, and environmental impact. Gasoline is the most common fuel type, but propane and diesel generators may offer better fuel efficiency and longer run times. Consider the fuel type that best suits your needs and preferences. In addition to fuel type, it’s essential to consider the generator’s fuel efficiency. Some inverter generators feature a fuel-saving or idle mode that consumes less fuel to produce the same amount of power, saving you money and reducing your environmental impact.

Run time

The run time of an inverter generator refers to how long it can operate on a full tank of fuel. This time can vary depending on the generator’s fuel efficiency and tank size. If you plan on using an inverter generator during long power outages or extended camping trips, it’s crucial to pick a generator that can run for up to 12 hours on a single tank of gas.

Parallel capability

Some inverter generators have parallel capability, which allows you to connect two or more generators to increase the total power output. This capability can be useful if your power needs grow over time or you want the flexibility to power more devices simultaneously.

Safety features

Inverter generators should have various safety features to ensure safe operation and protect the generator and your devices. Here are some essential safety features to look for.

  • Low-oil shutoff automatically shuts off the generator’s engine when the oil level is too low, preventing engine damage due to insufficient lubrication.
  • Overload protection prevents damage to the generator and your devices by automatically shutting off the power when the generator is overloaded.
  • Surge protection protects your sensitive electronics from voltage spikes and surges, which can occur when the generator is started or stopped.
  • GFCI Outlets automatically shut off power when they detect an imbalance in the electrical current, protecting you from electric shock.
  • A spark arrestor is a device that prevents the emission of flammable debris from the generator’s exhaust, reducing the risk of fire.

Certifications

Certification by recognized organizations can provide an added level of assurance that the inverter generator meets specific safety, performance, and environmental standards. Some notable certifications to look for include EPA and CARB.EPA ( Environmental Protection Agency) certification ensures that the generator meets the agency’s emissions standards, which can be particularly important if you live in an area with strict air quality regulations. CARB (California Air Resources Board) certification is a must-have for generators sold in California, and it indicates that the generator complies with the state’s stringent emissions standards.

Noise level

One of the main advantages of inverter generators is their quiet operation compared to traditional generators. Noise levels can still vary between models. If you plan to use your generator in a residential area or a campground with noise restrictions, look for a model with a low decibel (dB) rating. A difference of just a few decibels can make a difference in perceived noise levels.

Portability

Inverter generators are generally more compact and lightweight than traditional generators, making them easier to transport and store. Consider the generator’s weight, size, and any additional features, such as wheels or handles, to make it easier to move and maneuver.

People Also Asked

Can I use an inverter generator inside my house?

No, you should never use an inverter generator inside your house due to the dangers of carbon monoxide poisoning. Always operate generators outdoors, away from windows and doors, to ensure proper ventilation and prevent harmful exhaust fumes from entering your home.

How long can an inverter generator run continuously?

The run time of an inverter generator varies depending on the model and fuel capacity. Most inverter generators can run for 8-10 hours at 50% load, but some models can run for up to 20 hours.

Can I connect two inverter generators for more power?

Yes, many inverter generators can be connected in parallel to increase the overall power output. Ensure that both generators are compatible and have the same output voltage and frequency to prevent damage to your appliances.

What type of fuel do inverter generators use?

Most inverter generators run on gasoline, but some models can also use propane or natural gas. Check the manufacturer's recommendations for the specific fuel type and octane rating required for your generator.

How do I maintain my inverter generator?

Proper maintenance is essential for the longevity and performance of your inverter generator. This maintenance includes regular oil changes, air filter cleaning or replacement, spark plug maintenance, and fuel stabilizer use during storage.

What appliances can I power with an inverter generator?

Inverter generators can power a wide range of appliances, including refrigerators, coffee makers, microwaves, and sensitive electronics like laptops and TVs. Always check the power requirements of your devices and the generator's output capacity to ensure compatibility.

What is the difference between a pure sine wave and a modified sine wave inverter generator?

A pure sine wave inverter generator produces a smooth, clean power output similar to the electricity from a utility grid, making it ideal for sensitive electronics. A modified sine wave generator produces a less consistent power output, which may cause issues with some devices.

How do I store my inverter generator when not in use?

When storing your inverter generator, ensure it is clean, dry, and free of debris. Drain the fuel and add a fuel stabilizer to prevent gumming. Disconnect the battery and remove the spark plugs to prevent accidental starting. Cover your inverter generator with a tarp or other protective covering, although this is not required.

What is the typical lifespan of an inverter generator?

The lifespan of an inverter generator depends on factors such as usage, maintenance, and build quality. With proper care and maintenance, most inverter generators can last for several years or even a decade.
