How To Choose The Best Standby Generator For Your Home?
Long-term power outages can be frustrating for anyone trying to carry on their daily lives without the basic needs that depend on electricity. Suppose you live in an area that is prone to power outages due to natural calamities or other factors. In that case, an alternate energy source is a really good idea, and an investment in a standby generator is well worth considering.
There's a wide selection of standby generators on the market, and not all of them are made equal. Some of the top products on the market today include models by Champion, Generac, Kohler, and Briggs & Stratton. This guide will help you choose the best standby generator for your home.
However, before I dive into the list, there are several things one must first consider before choosing their new home generator:
- Quiet Operation. As your generator is going to be near your house, it needs to be quiet. Most standby generators use technologies that keep the noise at residential-friendly levels.
- Improved fuel efficiency. The generators I have chosen feature advanced, automotive-style engines, which are more fuel-efficient.
- Liquid-cooled. These generators can handle prolonged outage periods as they are typically liquid-cooled.
- Longer maintenance intervals. I have chosen standby generators that can go for extended periods between maintenance, as compared to their portable counterparts. This can save you lots of money and hassle in the long run.
Best Standby Generators: My Top Picks
Once you understand what to look for from your new standby generator, it will be much easier to pick the one that will suit your needs best. And to help you make the right pick, here's my list of the best whole house generators:
1. Champion Power Equipment 100294 - OUR NUMBER ONE PICK
[amazon fields="B01MYN8Y7Y" value="thumb" image_size="large"]
[amazon fields="B01MYN8Y7Y" value="button"]
For me, the best home generator available is definitely this 14-kilowatt home standby generator from Champion Power Equipment. It was designed and engineered in the United States and provides a permanent source of backup power.
Whenever there is a power cut, the generator will automatically start and deliver continuous power to your whole house. However, in my opinion, the most noteworthy feature of this home standby generator is its engine.
The unit is fitted with a Milwaukee series 754cc 2-cylinder engine that continuously delivers 14 kilowatts (58.3A x 240V) when powered by propane and 12.5 kilowatts (52.1A x 240V) when powered by natural gas. You connect the generator directly to your fuel system, eliminating the need for refueling.
The generator's innovative 24-volt starting system ensures that the generator starts reliably in temperatures ranging from -22° F to 104° F. The onboard battery charger maintains the charge 24/7 to ensure that you have enough starting power when you need it.
The generator's enclosure has an all-weather design with a composite mounting pad that protects the unit from the elements. The enclosure itself is resistant to rust, and it has an innovative gull-wing design that provides easy access to the engine and a full view of the onboard control system.
This system provides control over all the generator's functions, including automatic transfer switch control, start and stop features, weekly testing and exercise functions, and utility monitoring.
