How to Choose Whole House Generators
Power Output Requirements
When selecting a whole house generator, know the power you need. Calculate the total wattage of all the appliances you want to run during an outage. A rule of thumb is to have a generator that offers at least 20% more power than your total wattage. For example, if your devices need 10,000 watts, look for a generator with at least 12,000 watts.
Fuel Type Considerations
Generators can run on different fuels, like gasoline, propane, or natural gas. Gasoline generators are often easier to find but tend to be less efficient. Propane generators are cleaner and can provide longer run times. Dual fuel generators offer the flexibility to switch between fuels, making them a versatile choice.
Run Time and Fuel Tank Size
Check the generator’s run time on a full tank. For home use, aim for a generator that can run for at least 10 hours on a single tank. Larger fuel tanks usually mean longer run times. A generator with a 6-gallon tank is a good standard choice.
Transfer Switch Compatibility
Ensure your generator is compatible with a transfer switch. A transfer switch allows you to safely connect your generator to your home’s electrical system. This helps avoid backfeeding, which can be dangerous. Some models come with a transfer switch, while others require it to be purchased separately.
Noise Level
Consider the noise level of your generator, especially in residential areas. Look for models that operate at 60 decibels or less. Generators with quieter engines are preferable, as they minimize disturbance while running. Always check the manufacturer’s specifications for noise ratings.
