Of course, it is nice to have a backup power supply for your home in case of a power outage, but automatic home generators take the convenience to another level. Immediately an outage occurs, they’ll kick in without anyone lifting a finger.  In some cases, you may not even realize that there’s an outage except for the sound of the generator.

The best time to appreciate your automatic home generator is when you’re sleeping. When a power outage occurs in the middle of the night, getting up to start your generator will be very difficult.

But when you have an automatic generator, you won’t even need to get up. In fact, you may not even wake up because your automatic generator will start itself automatically.

Do Home Generators Turn on Automatically?

The answer is yes and no. It depends on the size of the generator. Portable generators usually do not start automatically. They often offer two manual starting methods. You can start portable generators through their recoil start by pulling the recoil handle swiftly. Also, you can start portable generators with a key. This is more convenient.

On the other hand, bigger heavy-duty generators, like the Generac 20KW generator, start automatically. That’s why it has to be installed with an automatic transfer switch. However, they may fail to start automatically when there’s a fault. In that case, you have to clear the fault and reset such generators.

Can A Standby Generator Be Used Continuously?

Yes, you can run a standby generator for several hours or days, but after a certain number of hours, you must allow them to rest, depending on the manufacturer’s recommendations. Also, if it runs out of fuel, you have to shut it down to refuel it.

Furthermore, when the engine oil level of a standby generator is low, the generator will automatically shut down and it will never start again until you top up the oil. This is a safety measure to protect the generator.

How to Install A Standby Generator with Automatic Transfer Switch?

Step 1 – Install the generator from all windows and doors at least 5 feet away.

Step 2 – The generator must be placed on a casted concrete pad because of its vibration.

Step 3 – You can then secure the generator on the pad with four strong steel bolts.

Step 4 – Contact a plumber to connect a natural gas line to the generator. That will be its source of fuel.

Step 5 – Run a line-voltage cable to the generator. This is the job of an electrician. Don’t do this yourself if you’re not a certified electrician.

Step 6 – Install a transfer switch near the electrical meter. The function of the switch is to direct electricity from the generator into the house when the generator starts working.

While we encourage you to do a lot of tasks yourself, we don’t think the installation of a standby generator is among. It is better to hire an expert for the installation. Don’t risk the wrong installation.

How Much is An Automatic Home Standby Generator?

Remember that standby generators come in various sizes, designs, and outputs. The most important factor that determines the cost of a generator is its power output. The higher the power output, the higher its cost will be, with all other factors being equal.

For instance, a 22KW generator will cost you more than a 20KW generator. So, if a 20KW can power all your appliances, you don’t need to pay more for a generator with a higher capacity.

The second factor that affects the cost of generators is size. Bigger generators are more expensive than smaller ones. Also, generators of popular brands are costlier than generators built by little-known brands. That being said, we can safely say that the prices of automatic generators begin from $6,750. There’s no cap to it.
