Sizing Considerations
Figuring out the right size generator for your home is super important to keep your essentials up and running when the lights go out. This part will walk you through what to keep in mind when choosing a generator.
Matching Generator Size to Home Size
How big your home is directly affects which generator wattage you’ll need. Bigger homes with more rooms and gizmos will naturally call for more juice than smaller ones. Give our handy whole house generator wattage calculator a crack to get a ballpark figure for your place and its must-have appliances.

To nail it down more accurately, think about things like HVAC units, kitchen gadgets, and other energy-hungry stuff in your crib.
Load Management Systems
Load management systems are like the secret sauce for stretching your generator’s juice. They figure out what needs power the most, so your generator doesn’t fry under pressure. With clever load management, you might get away with a smaller generator doing more heavy lifting.
