How to Buy the Best Standby Generator


You won’t need to read tons of the best standby generator reviews to understand the importance of getting a piece of equipment that offers permanent power protection. A standby generator is vital as a long-term back-up solution, as it provides dependable power on demand. It is important to know what factors need to be considered prior to purchase of such gear, as we’re talking long term solution here and not just a simple remedy.


Power and Capacity

The best standby generator reviews often feature units with two basic power parameters. They can either be running or continuous watts, or start-up power, peak power, starting or max watts. Under normal load, appliances require continuous power to run. For appliances to start up or run at their optimum levels of power consumption, starting wattage is needed.

The top rated standby generators 2022 create power between 5,000 to 25,000 watts or higher. Power tools in your work site may need up to 8,000 watts.In choosing a unit of this type, you will have to prove that it is able to supply enough continuous and peak wattage for the appliances that have to be powered on the circuit. A standby generator can either be a bigger liquid-cooled type that produces more power, or an air-cooled model.



Plenty of homeowners choose to power selected circuits only and not all circuits during an outage. Those circuits most commonly considered essential are those involved in heating and cooling systems, lights, refrigeration, or well pumps. These not only cover basic emergency use but keeping them powered is also an economical option.


Features and Accessories

A transfer switch enables managed power generation to support every part of the home, or just a part of it.

The best standby generator 2022 works with either an automatic or a manual transfer switch. People prefer automatic transfer switches as they sense when utility power is lost and automatically switch generator power on.

Portable models can be easily transported when they have a wheeled frame. The smallest portable generator is lightweight and is easily carried. A model that’s several hundred pounds heavy will still need a wheeled frame to be moved out of storage when backup power is needed.

Units geared with noise dampening elements, such as large mufflers, can reduce the noise that usually accompanies emergency power generation.
