Buying Guide for Whole House Automatic Generators
Selecting the best whole house automatic generator requires consideration across several factors to ensure it fits your home’s power demands and installation environment.
Power Output
Calculate your home’s total wattage need by listing essential appliances and systems. Generators range from under 10kW for basic loads to over 22kW for comprehensive whole house coverage. Choose a generator rated slightly above your peak load to accommodate startup surges.
Fuel Type and Availability
Natural gas, propane, and gasoline are common fuels. Generators that support dual fuel (gasoline and propane) provide flexibility. Natural gas and propane tend to be cleaner and have longer storage life than gasoline but availability may vary. Consider which fuels are accessible and cost-effective in your area.
Transfer Switch Compatibility
The transfer switch safely switches your home’s power source to generator power automatically. Ensure the generator comes with an appropriate switch or is compatible with one that fits your electrical setup. Switch amps ratings must align with your home’s electrical panel capacity.
Installation and Maintenance
Look for generators with features like WiFi monitoring, easy access panels, and robust enclosures for simpler upkeep. Professional installation is recommended. Consider noise levels if the unit will be near living areas; some models include sound dampening to reduce operational noise.
Durability and Warranty
Choose generators constructed with weather-resistant materials such as aluminum enclosures, and check manufacturer warranties for assurance. Longer warranties indicate greater confidence in product durability.
Additional Features
- Remote monitoring via WiFi or mobile apps
- Cold-weather starting capabilities
- Self-diagnostic testing
- CO detection for safety in dual fuel options
By evaluating these factors, you can choose a whole house automatic generator that best fits your power needs and enhances your home’s energy resilience.
