A standby generator is a back-up electrical system that operates automatically. ... After utility power returns, the automatic transfer switch transfers the electrical load back to the utility and signals the standby generator to shut off. It then returns to standby mode where it awaits the next outage.
As a homeowner, buying a generator could spare you financial losses, like food spoilage, when power outages strike. Also, if you work from home, a standby generator is a solid investment, as it ensures you won't suffer a loss of income due to circumstances outside your control.
A standby generator is fully enclosed, while a portable generator has exposed engine parts, which are often very hot. Standby generators turn on automatically when the power shuts off. ... A portable generator must be manually started and stopped – meaning the homeowner must be home during a power outage.
When the generator detects a power outage, the engine starts automatically and turns a power generating unit called an alternator. The alternator converts the mechanical energy of the internal combustion engine into electrical energy.
Power outages, especially extended outages, will require running your generator for more time. Typically, standby generators have a lifespan of 20-40 years, depending on how often they run and how well they are maintained.
For homeowners wanting the ultimate entry-level whole-house standby, a 22kW is a perfect choice to reap all of the benefits of a whole-house generator over a regular home standby. A generator in the 27-36kW range is perfect for most homes since they replace 75% of the 200 amps coming into your electrical panel.
A 20kW generator will run most house receptacles, lights, and up to a 5-ton central air conditioner. ... You have a second air conditioner and heating system for the upstairs, but this area of the home is not important to you while operating on generator power.
Recommended Running Time and Refueling Requirements
While some models have been manufactured to provide power for days at a time, most generators can be run for 8-, 12-, or 24-hour intervals–with a few boasting 72-hours running times.
Pros: Portable generators are cheaper to buy and install than home standby models. When connected to your home's circuit-breaker panel with a transfer switch, they can power almost as much as a home standby generator.
Installing a generator "legally" can increase the resale value of your home. ... A 2014 report by Remodeling Magazine indicated that installing a standby generator can provide up to a 150% return on your investment. Meaning, if you spent $12,000 on installing a generator, your home value may increase up to $18,000.
Yes, you can run a generator overnight, but there are a few problems that you will have to deal with. ... Never refuel a running generator, even a generator with a still-hot engine because heat from the engine parts or exhaust could ignite the gasoline. Turn the generator off overnight (your neighbors will be happy, too).
You can run the most critical household equipment with a generator rated at 5,000 to 7,500 watts. These include things like a well pump, refrigerator and freezer, and lighting circuits. A generator with around 7500 running watts can run all these appliances at once. For RV, a 3000 – 4000-watt generator would be ideal.
In an emergency, a portable generator for house use is easy to operate. All you have to do is add fuel, start the engine, and run extension cords. Alternatively, you can eliminate extension cords by using a transfer switch with your portable generator.
