10 Best Whole House Generators 2025 in the United States

The Generac 7043 22kW Air Cooled Guardian Series Home Standby Generator stands out as a solid option for anyone looking to ensure their home has reliable power during outages. Its impressive 22,000 watts of power output means it can support most home appliances, making it suitable for residential use. The generator runs on natural gas or LP gas, offering flexibility in fuel choice, which is a strong point for varied household needs.

The installation process is straightforward, although it’s recommended to have a certified electrician set it up for safety and compliance. For peace of mind, the generator comes with a 200-amp automatic transfer switch that ensures seamless power transfer during an outage, keeping your home fully protected.

One of its standout features is the Mobile Link Wi-Fi connectivity, which allows users to monitor generator performance remotely. This is particularly beneficial for those who travel or want to keep tabs on their system without being physically present. Additionally, the 5-Year Limited Warranty reflects Generac’s confidence in the product's durability and performance.

On the downside, the generator is relatively heavy at 466 pounds, which can make installation a bit challenging if not managed properly. Additionally, as it requires professional installation, upfront costs may be higher than anticipated for some homeowners. The Generac 7043 is designed for those who prioritize reliability and ease of use in a whole-house generator, especially for residential settings. While it has some weight and installation considerations, its performance and smart features make it a worthwhile investment for maintaining power during outages.

The DuroMax XP16000iHT is a powerful portable generator designed to handle whole-house power needs, offering a solid 13,000 running watts and 16,000 peak watts. Its standout feature is the tri-fuel capability, allowing you to run it on gasoline, propane, or natural gas, which adds great flexibility depending on what fuel you have available. This model includes two 50-amp outlets, making it easy to connect directly to a transfer switch or interlock system for whole-home backup during outages. The remote electric start is a convenient touch, letting you start the generator from inside your home without going outside in bad weather. Safety is also well considered with its carbon monoxide sensor that automatically shuts the unit off if dangerous levels are detected.

It uses inverter technology to produce clean, stable power, which is good for sensitive electronics, and its noise levels are relatively low for a generator of this size, making it more suitable for residential use. The runtime is about 18 hours on a full tank, which is decent for extended outages, though the 10.5-gallon fuel tank adds to the unit’s considerable weight and size (over 500 pounds and roughly 3 feet tall). This means professional installation and a good spot for placement are important considerations. While it’s portable in theory, its heavy weight and size might make moving it challenging without assistance or equipment.

Some users report average reliability and noise can still be noticeable compared to smaller home generators. This generator represents a strong choice if you want flexible fuel options and enough power to cover an entire home, especially if you can handle its size and weight. It suits homeowners looking for a reliable backup during storms or power failures, but may be overkill for smaller properties or casual use.
