How Do Backup Generators Work?
With blackouts and energy issues becoming more common worldwide, it’s increasingly important to be prepared for power outages. One effective solution is to use a backup generator.
How do they work?
In this example, we will focus on the Generac home backup generator. This model is especially useful because, in the event of a power outage, it turns on automatically to provide power until utility service is restored. This could be a few hours or, in an emergency, up to several months, offering reassurance that your energy needs are covered.
The generator allows for “load shedding,” prioritizing essential appliances if necessary. While it doesn’t turn on instantly, it checks to ensure an actual outage rather than a temporary flicker. This process usually takes only a couple of minutes, so there’s no need to worry if it doesn’t activate immediately.
These backup generators operate using either liquid propane or your home’s gas line. The engine and alternator are housed in a shielded box on a concrete pad, designed to withstand extreme weather. The switch isolates from utility lines to protect workers and reduce the risk of generator overload.
How do you test them?
You can also test the generator using “exercise” mode. In this mode, the generator can be set to run at a specific time to warm up. The machine effectively checks itself, ensures everything is functioning properly, and then shuts down automatically. During this time, power will not be interrupted, and there will be no switch transfers.
Is the generator noisy?
Some people may be concerned about the noise from running the generator. However, permanent generators are legally required not to exceed certain decibel levels. In fact, the noise level of these generators is comparable to common household devices like air conditioners, blenders, and vacuum cleaners.
What do I need to install?
If you want to install a generator, place it as close to your electric and gas meters as possible, maintaining about 18 inches of distance from your property to prevent exhaust gases from entering your home. Additionally, check with local housing associations and building codes before installation, and consider discussing it with your neighbors.
The price of the generator will vary depending on whether the estimate includes the transfer switch, installation, and the unit itself, as well as factors like the type of gas used and the amount of materials required. You can opt for pre-packed units, or for greater peace of mind, use the services of a local qualified Generac contractor, like Handyside!
