The Benefits of A Standby Generator For Your Home


Higher wattage ranges allow standby generators to power more of your house for extended periods of time. Standby generators with the highest power outputs are known as whole-home generators because they could potentially run your entire house if sized correctly.

Standby generators provide an easy way to generate power without having to deal with constantly refilling the gasoline or operating power cords. This keeps the risk of fire, carbon monoxide poisoning, and electrical shock at an all-time low.

Home standby generators provide you with the peace of mind that comes from knowing your critical systems will be back up and running just as efficiently as they were before in the event of a power outage. You’ll be able to continue working on your computer or watching your favorite show as if nothing ever happened!


A standby generator will pay for itself each time the power goes out by ensuring that your electronics stay safe and sound during a blackout. In addition, it could potentially increase the resale value of your property.

Having a generator to serve your home can be greatly advantageous, especially during stormy seasons –– it will give you peace of mind when the storms start rolling in. However, for your newly installed generator to serve its purpose, it must function properly.
