Buying Guide For Gas Backup Generators
Choosing the best gas backup generator involves considering multiple factors based on your power needs and usage scenarios. Here are key points to guide your selection:
Power Output
The wattage rating determines what appliances and systems your generator can support. Identify your essential load requirements by summing wattage of refrigerators, HVAC, sump pumps, and electronics. Select a generator with running watts slightly above this total for reliable performance.
Fuel Type and Flexibility
Gasoline remains the most common fuel due to availability and ease of refilling. However, tri-fuel generators offer flexibility, allowing operation on propane and natural gas, useful if one fuel source is scarce. Propane is cleaner and stores indefinitely, while natural gas can be connected for unlimited supply if available.
Run Time And Fuel Tank Size
Longer runtime reduces the need for refueling during outages. Larger fuel tanks or efficient fuel consumption extend operational periods. Check manufacturer data on run time at typical load levels to ensure sufficient coverage.
Starting Mechanism
Remote electric start adds convenience, especially in adverse weather or emergency situations. Recoil (manual) start provides backup if the battery fails but may require more effort.
Safety Features
Look for generators with CO sensors or automatic shutdown to prevent carbon monoxide poisoning. Automatic low oil shutdown protects the engine. Ground fault circuit interrupters (GFCI) on outlets add user protection.
Transfer Switch Compatibility
If you intend to connect your generator to your home’s electrical system, transfer switch readiness is crucial. This feature ensures safe and code-compliant power transfer.
Portability and Size
Consider weight, wheel kits, and handles if you plan to move the generator frequently. Larger models provide more power but may be less portable.
By assessing these factors and matching them to your home’s power demands and convenience preferences, you can select a gas backup generator that reliably keeps your essential systems powered during outages.
