10 Best Generators 2026 in the United States

The Generac Guardian 26kW Home Standby Generator is a solid choice for homeowners needing reliable backup power during outages, storms, or emergencies. It offers a powerful 26,000-watt output, enough to support an entire home, which means you can keep most or all of your essential appliances running simultaneously. This model runs on natural gas or liquid propane, giving flexibility depending on your available fuel sources. It features Generac's G-Force 1000 Series engine known for durability and efficient fuel use, which helps keep operational costs lower over time.

This generator is designed for stationary home installation and weighs 518 pounds, so it's not portable but meant as a permanent backup solution. Noise levels are kept relatively low with a 'Super Quiet' feature and a Quiet-Test mode that reduces engine speed during self-tests, making it less disruptive to your household and neighbors. Four power outlets provide ample connectivity options for your home's needs. One standout feature is the built-in Wi-Fi monitoring that lets you track the unit's status and maintenance alerts remotely, adding convenience and peace of mind.

Installation requires a certified electrician, which may add to upfront costs but ensures the unit operates safely and efficiently. The size and weight make it unsuitable if you need a portable generator or have space constraints. Also, because it’s designed for whole-house use, it may be more generator than some users need if they only require backup for a few essential devices. The 5-year warranty provides added reassurance typical for this level of investment. This generator is well-suited for homeowners looking for reliable, quiet, and relatively low-maintenance whole-house backup power but less suited for those needing portability or a lightweight option.

The Generac 7210 24kW Air Cooled Guardian Series Home Standby Generator is a robust choice for homeowners looking for dependable power during outages. One of its standout features is the impressive 24,000 watts of power output, which is more than sufficient to keep essential appliances running smoothly. The generator is designed to operate on natural gas or LP gas, making it flexible regarding fuel options. Its 200-amp transfer switch ensures that your entire home can be powered, providing peace of mind during unexpected blackouts.

Portability may not be a strong suit, as this generator weighs 455 pounds, making it more suitable for stationary installation rather than frequent relocation. On the positive side, the unit is engineered for easy installation by a licensed electrician, so you won't have to worry about the technicalities of setup.

A significant advantage is the Wi-Fi connectivity through Mobile Link, enabling remote monitoring. This allows you to check the generator's performance from anywhere and receive alerts about maintenance, which is especially useful for busy homeowners. While the generator is built to last and backed by a 5-year limited warranty, some users may find the initial investment to be significant. However, the quality of the G-Force engine and the advanced True Power Technology, which ensures clean energy with minimal distortion, justify the cost for many.

The Generac Guardian 22kW Home Standby Generator is a strong choice for homeowners looking for reliable whole-house backup power during storms or outages. It delivers a powerful 22,000 watts, enough to keep most home appliances running smoothly. You can run it on natural gas or liquid propane, giving flexibility depending on your fuel availability. Thanks to its automatic features like idle control and voltage regulation, it works efficiently and safely with minimal fuss. It’s designed to be durable and quiet compared to many generators, which is helpful if you want to avoid loud noise during emergencies.

One standout feature is the built-in Wi-Fi connectivity that lets you monitor the generator remotely, so you’ll always know its status and get maintenance alerts even if you’re away from home. The included 200 Amp automatic transfer switch ensures your home's electrical system transitions seamlessly to generator power when needed. With 30 power outlets, it can support a wide range of devices and appliances.

This generator is quite heavy (466 pounds) and fairly large, so it’s not something you’d move around frequently. Installation requires a licensed electrician, which adds to the setup cost and complexity. This unit is built for permanent outdoor installation and isn’t portable like smaller generators. If you want a robust, low-maintenance standby generator that covers your entire home and offers modern remote monitoring, this Generac model fits well. It’s not ideal for those needing a lightweight or portable solution but excels in providing dependable power when you need it most.
