Buying Guide: How to Choose the Best Generac Generator for Your Home

Power Output: Match Generator Size to Your Home’s Needs

The most critical factor is power output. A whole-home standby generator like the Generac 22kW can run central air conditioning, well pumps, and kitchen appliances simultaneously. For smaller homes or apartments, a 10kW model may suffice.

Consider the essentials you need to power during an outage. List the wattage of each appliance and add them up. This will help you determine whether you need a 14kW, 22kW, or even 26kW unit. For a detailed comparison, see our best residential standby generator for home article.

Fuel Type: Natural Gas, Propane, or Dual-Fuel

Generac generators run on natural gas, propane, or both. Standby models are typically connected to your home’s natural gas line, providing unlimited fuel during extended outages. Portable inverters like the Generac 3,800 Watt Dual-Fuel offer flexibility, allowing you to switch between gasoline and propane.

Think about fuel availability and storage. Natural gas is convenient but may be disrupted during earthquakes. Propane has a long shelf life, making it a reliable backup. Dual-fuel models give you the best of both worlds.

Installation and Transfer Switch

Standby generators require professional installation and an automatic transfer switch. This switch detects power loss and seamlessly transfers your home to generator power. Generac models often include a 200-amp transfer switch, ensuring compatibility with most homes.

Portable generators, on the other hand, are plug-and-play but require manual setup during outages. If you prefer a hands-off approach, a standby generator is worth the investment.

Smart Features and Remote Monitoring

Modern Generac generators come with built-in cellular or Wi-Fi connectivity, allowing you to monitor performance and receive maintenance alerts via the Mobile Link app. This feature is invaluable for checking your generator’s status while away from home.

Some models also integrate with smart thermostats and battery storage systems, creating a comprehensive home energy ecosystem. For RV or camping use, the portable inverter’s parallel capability lets you double your power output.

Final Thoughts

Choosing the best Generac generator for home depends on your specific power needs and lifestyle. For whole-home protection, the Generac 22kW Whole Home Generator offers a perfect balance of power and value, while the Generac 3,800 Watt Dual-Fuel Portable Inverter is ideal for portable backup and outdoor adventures. Both models deliver the reliability Generac is known for, ensuring you stay powered when it matters most.
