You’ve Decided What Type to Get…Now What?

Once you’ve chosen the type of generator that suits your needs, it’s time to dig a little deeper. There are several key features and considerations that can make or break your generator experience. To ensure you make the right choice, let’s go through the essential details to consider before finalizing your purchase.

1. How Much Power Should You Get?

Understanding your power needs is crucial in selecting the right generator. Generators are rated by wattage, and choosing the correct wattage ensures that the unit can handle all the devices and appliances you plan to run.

• Running watts are the amount of continuous power the generator provides.
• Starting watts are the surge of power needed to start appliances with motors, such as refrigerators or air conditioners.

To calculate your needs, make a list of everything you want to power during an outage or on your camping trip, noting both the running and starting wattage. Add these up, and choose a generator that can handle the load comfortably.

Tip: Always opt for a generator that provides slightly more power than you expect to need. This will prevent overloading and ensure smooth operation.

2. Transfer Switch vs. Interlock Device

If you’re buying a generator for home use, particularly a standby or portable unit, you’ll need a way to connect it to your home’s electrical system. This is where a transfer switch or interlock device comes in.

• Transfer switch: A transfer switch is a dedicated panel that isolates your home’s circuits from the power grid, ensuring safe generator use during an outage. This option is more expensive but provides the highest level of safety and convenience.
• Interlock device: An interlock is a more affordable alternative to a transfer switch. It prevents the main electrical panel from operating while the generator is connected, offering basic protection from backfeeding.

Which is better?

If you want the most seamless and professional solution, a transfer switch is worth the investment. However, for homeowners on a budget, an interlock device can still provide safe operation, as long as it’s used properly.

3. How Many Outlets Do You Need?

Different generators come with a variety of outlet configurations, and your choice will depend on what devices you want to power.

• Standard 120V outlets: Perfect for powering smaller devices like lights, fans, and small appliances.
• 240V outlets: Needed for high-wattage devices like dryers, water heaters, or heavy-duty tools.
• USB ports: Useful for charging smaller electronics like phones and tablets, often found on inverter generators.

Consider your expected use and make sure your generator has enough outlets and the right types of outlets for your needs.

4. What Fuel Type is Best?

Generators can run on various fuel types, each with its advantages and disadvantages:

• Gasoline: The most common and widely available fuel, but it’s not the best for long-term storage.
• Propane: Cleaner-burning and easy to store, but propane-powered generators can have lower power output compared to gasoline models.
• Natural gas: A great option for home standby generators as it provides an unlimited fuel source as long as you’re connected to the grid.
• Dual-fuel: Some generators can run on both gasoline and propane, offering flexibility in fuel choice based on availability.

Which fuel should you choose?

If you’re purchasing a home standby generator, natural gas or propane might be your best bet. For portable and inverter generators, gasoline is the most convenient option, though dual-fuel models offer the best of both worlds.

5. Fuel Gauge and Low-Fuel Shutoff

Monitoring your fuel level is essential, especially during extended outages. A fuel gauge lets you easily keep track of how much fuel remains, helping you plan when to refill.

A low-fuel shutoff feature automatically turns off the generator when fuel levels are too low. This prevents damage to the engine and gives you peace of mind when you’re away or unable to refill the tank immediately.

Tip: Always look for generators that include both features for hassle-free operation and longer engine life.

6. Push Start, Pull Start, or Automatic Start?

Starting methods vary between generators, and the right choice depends on your personal preference and ease of use.

• Pull start: The traditional way to start a generator by pulling a cord. It’s simple but requires some physical effort.
• Push start: Offers the convenience of starting your generator with a push of a button, often seen on mid-range and high-end portable generators.
• Automatic start: Typically found on home standby generators, this feature allows the unit to start automatically when a power outage is detected—perfect for those who don’t want to worry about manually starting the generator.

Which is best for you?

If ease of use is a priority, push-start or automatic-start options are more convenient. For occasional use, a pull start might be sufficient and keeps costs down.

7. Final Generator Buying Checklist

Before making your final decision, go over this checklist to ensure you’re choosing the right generator:

• Power needs: Have you calculated your running and starting wattage requirements?
• Connection method: Will you need a transfer switch or interlock device for home use?
• Outlets: Does the generator have enough outlets (and the right types) for your needs?
• Fuel type: Which fuel type is most accessible and efficient for your situation?
• Convenience features: Does the generator include a fuel gauge, low-fuel shutoff, and the type of start you prefer?
• Noise level: Is noise a concern? If so, an inverter generator might be a quieter option.
• Portability: If you plan to move the generator around, consider the weight, handle design, and whether it has wheels.

By following these guidelines and carefully considering the essential features, you can confidently select a generator that fits your needs, whether you’re preparing for emergencies, enjoying outdoor activities, or ensuring a seamless power supply for your home. A little extra planning now can save you a lot of frustration down the line, ensuring that your new generator will be ready to serve you when you need it most.
