Buying Guide for Whole House Generators
Choosing the right whole house generator involves several important factors to ensure reliable and efficient power backup tailored to your needs. Consider the following:
Power Output and Home Size
Estimate your total home wattage needs by adding the power requirements of all essential appliances and systems you want to run simultaneously. Whole house generators typically range from 10,000 watts to 24,000+ watts. Larger homes or those with high power needs may require higher capacity like the Generac 24kW or Champion 22kW models.
Fuel Type and Availability
Standby generators often run on natural gas or propane with automatic transfer switches, providing seamless, unattended operation. Dual fuel portable generators offer gasoline and propane flexibility, valuable for portability and emergency backup. Consider fuel availability, storage, and emissions when choosing the fuel system.
Installation and Transfer Switch
An automatic transfer switch is critical for standby generators, facilitating safe and automatic switching during outages without manual intervention. Check if the generator includes a compatible transfer switch, and consider professional installation for safety and code compliance. Some portable units are transfer switch ready but may require manual setup.
Operation Features and Safety
Look for convenient features like electric or remote start, WiFi monitoring, self-diagnostics, and quiet operation. Safety features such as carbon monoxide detection are vital for portable generators that operate close to living areas.
Portability Versus Permanent Installation
Standby generators are permanently installed outdoors and connect directly to home electrical systems. Portables offer mobility, are usually smaller, and can be used in multiple settings but may require manual setup to power critical loads.
Maintenance and Warranty
Regular maintenance is essential for generator longevity. Review manufacturer warranty terms and consider models with extended support and easy access to parts.
By carefully evaluating these aspects, you can select a whole house generator that offers the best combination of power, fuel options, safety, and convenience for your home.
