Buying Guide for Whole Home Generators
Choosing the right whole home generator involves multiple key factors:
Power Output and Capacity
Determine your home’s wattage needs by adding up key appliances and systems. Whole home generators typically range from 8,000 to 24,000 watts. Higher wattage models can handle larger homes and more equipment simultaneously.
Fuel Type Options
Consider fuel availability and convenience. Many whole home generators support gasoline, propane, and natural gas, offering fuel flexibility and longer runtime options. Tri-fuel models give users multiple backup fuel sources, increasing reliability during extended outages.
Start Method and Convenience
Remote electric start and key fob operation simplify generator activation, especially during emergencies. Traditional recoil starts are less convenient. Some models also provide transfer switch compatibility for seamless power transition.
Transfer Switch Compatibility
An automatic or manual transfer switch allows your generator to connect safely to home electrical systems. Check if the generator is transfer switch ready or if you need to purchase switch kits separately.
Run Time and Fuel Tank Size
Longer run times reduce refueling frequency. Larger fuel tanks and fuel-efficient engines help generators operate through prolonged outages. Consider propane or natural gas connections for extended runtimes without manual refueling.
Portability and Installation
Portable generators offer flexibility but may require manual setup. Standby units install outside for automatic operation but generally involve professional installation and higher upfront costs.
Safety Features
Look for automatic low oil shutoff, CO shutdown features, and covered outlets for increased operator and home safety during generator use.
Warranty and Support
A solid warranty period and brand reputation ensure your investment is protected and reliable customer support is available if issues occur.
