These settled generators remove many of the headaches associated with employing portable generators like continuous refueling, managing many feet of extension cords and enduring the regular din of a noisy motor.

Home standby generators are an investment, but they provide increased energy potential and are ready to use when the energy cuts out. They mainly range between 7 kW to 22 kW of energy or more once installed for use.

To keep essential devices such as your refrigerator or your air conditioning operating, home generators rely on propane or natural gas connection. Alternatively, you can use diesel-fueled generators, but be aware that extra codes may govern the setting of this kind of home standby generator.

Home generators differ in wattage and you must factor in both running watts and starting watts for your home’s energy supply demands.

Making it an excellent option as a standby generator or generator rental for medium houses. Heat is typically a major issue with standby generators.

For a device with a lot of complicated moving components, heat normally builds up the longer a generator operates. In order to resume performing without experiencing major, permanent harm, an instrument requires an appropriate cooling system.

For most affordable devices, this configuration swaps hot for cool air using some fans. The Briggs & Stratton 12,000 Watt device is all about heat control and efficiency in its model.

With a small enclosure and effective air cooling configuration, the system can perform for long periods without overheating. When selecting between a single-phase and three-phase device, you’ll want to meet your power demands.

Unlike your normal three-phase generator, single-phase generators generate one single voltage of energy. While more energy- and cost-efficient in the long operation, the ratings can change all over the power cycle.

This shouldn’t be an issue for normal and residential functions, but if you’re looking to energize a larger home in a more metropolitan region, opt for a multiple-phase choice.

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.

Step 3 – You should secure the generator on the pad with bolts.

Step 4 – Let a plumber connect a natural gas line to the generator.

Step 5 – Run a line-voltage cable to the generator.

Step 6 – Connect the generator to the power inlet box.

That’s it!
