Breaking Down the Watts: Peak vs. Running Power

Before you even start looking at models, it's crucial to understand the difference between a generator's "peak watts" (also known as starting watts) and "running watts" (also called continuous watts). This distinction is fundamental to choosing the right size.

Running Watts: This is the sustained power your generator can produce to keep appliances operating continuously. It's the most important number for matching your generator to your consistent power needs.
Peak Watts: This refers to the brief surge of extra power a generator can supply for a few seconds to start motor-driven appliances like refrigerators, air conditioners, or power saws. These devices require more power to kick on than they do to run.
To figure out your minimum required running wattage, list all the essential devices you want to power simultaneously. Add up their running wattages. Then, identify the device with the highest starting wattage and add that difference to your total running wattage. For instance, if your essentials sum up to 6,000 running watts, and your refrigerator needs an extra 1,200 watts to start, you'd aim for a generator with at least 6,000 running watts and around 7,200 peak watts. Many 7000-watt generators actually offer 8,000 running watts and 10,000 peak watts, providing a comfortable buffer.

The Powerhouse Lineup: Types of 7000-Watt Generators

When you're shopping for a 7000-watt class generator, you'll primarily encounter two main types: conventional portable generators and inverter generators. Each has its own strengths and ideal use cases.

Conventional Portable Generators: The Workhorses

These are the most common type of generator, known for their rugged design and ability to deliver raw power. They typically use an alternator directly connected to the engine, producing electricity at a fixed RPM.

Pros: Generally more affordable per watt, robust, and capable of handling high starting loads. They're excellent for powering heavy-duty tools on a job site or providing basic backup power for a home.
Cons: Tend to be louder, less fuel-efficient, and produce "dirty" power with higher Total Harmonic Distortion (THD), which can be harmful to sensitive electronics.
Examples: The Generac 7715 GP8000E is a prime example, offering 8,000 running watts (10,000 peak) on gasoline, featuring PowerRush Advanced Technology for extra starting capacity and an electric start. Similarly, the All Power APGG10000 delivers 8,000 running watts (10,000 starting) and comes with electric start, ready for dual-fuel operation.

Inverter Generators: Quiet Power, Clean Performance

Inverter generators represent a significant leap in generator technology. Instead of directly producing AC power, they convert the engine's raw power into DC, then use a sophisticated inverter to convert it back to clean AC power.

Pros: Produce "clean" power (low THD, typically under 3%), making them safe for sensitive electronics like laptops, smartphones, and medical equipment. They are significantly quieter, more fuel-efficient (as they can adjust engine speed to match the load), and often more compact.
Cons: Generally more expensive than conventional generators of comparable wattage.
Examples: The Honda EU7000IS is a benchmark for quiet, fuel-efficient inverter power, delivering 7,000 watts. Another excellent option is the Gidrox 7000W Dual Fuel Inverter Generator, which combines clean power (under 3% THD) with the versatility of dual-fuel capability, making it perfect for RVs with its dedicated adapter.

Gasoline generators typically have a built-in fuel tank, like the 9.5-gallon tank on some Westinghouse models, offering extended runtime.

Propane (LPG): Cleaner and More Storable

Pros: Propane burns cleaner than gasoline, reducing engine wear and emissions. It has a much longer shelf life and can be stored indefinitely in tanks, providing a reliable long-term fuel source. It's often readily available in common 20 lb or larger tanks.
Cons: Can be less fuel-efficient than gasoline (meaning you'll burn more propane for the same amount of power), and larger tanks can be bulky to transport.

Natural Gas: Unlimited Supply (with caveats)

Pros: If you have a natural gas line to your home, a natural gas-capable generator offers an almost unlimited, continuously supplied fuel source, eliminating the need for refueling. It's also cleaner burning.
Cons: Primarily suitable for stationary home backup as it requires a direct connection to a natural gas line, making it non-portable. Installation can be more complex and costly.

Dual-Fuel Generators: The Best of Both Worlds

Many popular 7000-watt generators, such as the DuroMax XP13000EH and All Power APGG10000, offer dual-fuel capability (gasoline and propane). This versatility is a huge advantage:

Use gasoline for quick starts and maximum power.
Switch to propane for longer, cleaner-burning operation, or if gasoline supply is limited.
Example: The Gidrox 7000W Dual Fuel Inverter Generator runs up to 12 hours at 25% load on gasoline from its 3.6-gallon tank.

Tri-Fuel Generators: Ultimate Flexibility

For the ultimate in fuel versatility, some heavy-duty generators in the 7000-watt class (and often exceeding it, like the Westinghouse 14500 Peak Watt Tri-Fuel and Westinghouse 13500 Peak Watt Tri-Fuel models) offer tri-fuel capability: gasoline, propane, and natural gas. This means you can tap into whatever fuel source is most convenient or available at the moment.
