Standby Generator, backup generators or automatic generator

What is a standby generator? Backup generators, or fixed electric generators, are a type of equipment to supply electric power. Its operation is the same as that of any other electric generator, with the difference that these are fixedly installed in one place. When we talk about domestic equipment, we refer to models which are designed to supply small electric charges ideal for homes or small offices.

Having a reserve system can guarantee us the supply of electricity in the event of a power failure, once the electric power service is restored, the electric charge is transferred and detected again by the generator, then it is automatically turned off, the fuel used by stand by generators is usually diesel, natural gas generator or liquid propane. These are much more complex systems than portable generators, and also considerably more costs, and finally with considerable benefits. Here you can find the best standby generators and residential generators with the best Amazon reviews, buy the standby generators for homes or commercial use on offer at an excellent price and get rid of the blackouts.

Characteristics of backup generators

The loads supplied by this equipment range from 5 KW to 45 KW in some models designed for large offices or even small stores.

  • They mostly operate with Natural Gas or Lp Gas, although some large models use diesel to be more cost efficient.
  • They are large equipment, and part of their acquisition cost includes the costs associated with their installation.
  • Unlike portable generators, stationary generator these tend to generate a lot of noise, so their installation includes a coating to isolate noise.
  • Unlike portable generators, they tend to get hot, so they require a cooling system.
  • The stand alone generator prices start at $ 1,600, with prices around $ 10,000 for higher loads (30 KW).

Cooling systems of standby generators

Reserve generators that are considered small in size (those that range from 15 KW to 20 KW) have a system based on cast air, which prevents the heating of the full house generator when taking air from the environment, other permanent generator of greater supply and power require other solutions for cooling, such as liquid cooling refrigeration systems.

Automatic supply system

How do automatic standby generators work? The new models that exist in the market of home standby generators allow an automatic and intelligent system that does not allow the supply of electric power to be interrupted in case of any failure or eventuality with the electricity supply, the home standby generator is perfect in any of these cases.

This is achieved through a transfer switch which must be installed on the electrical panel of the house, is necessary for the whole house standby generator (usually sold separately).

It is important to note that these automatic backup generator systems will not prevent connected equipment from shutting down for a brief moment, and may lose information in the case of computers, or may cause damage to other equipment. To protect against these risks, one can use UPS (suitable supplies to protect computers) and / or voltage regulators.

Automatic systems begin to operate after a short delay.

Safety in the use of permanent backup generators

  • A certified contractor or other qualified professional is required for the standby generator installation.
  • It must be ensured that the generator does not send electricity to the power lines, this is avoided by installing a double-shot bipolar switch, a professional or qualified technician can do this work for you.
  • When you purchase a Standby generator and make changes to the wiring, notify the relevant authorities or your city department.
  • It is necessary to carry out regular safety inspections and ensure that there is enough fuel for several days.

Standby generator distance from house

If you have already purchased an electric generator to be your support, emergency generator systems or main power equipment, the time has come to determine where you are going to install your new equipment. So let’s look at all the aspects that you will have to evaluate before starting up your equipment.

Let’s start with the foundations

Depending on the size of the electric generator it will be necessary for the floor or ceiling to support the total weight of the equipment, adding the fuel, oil and coolant. If we talk about a team that is very large, the ideal is that you have the advice of an engineer to assess the strength of the structure.

Also, keep in mind, especially if the structure is under construction, that a prudential space between the walls, preferably 1 or 2 meters, be maintained. And if possible, that an insulating layer be applied between the foundations and the floor, to prevent any risk of leaks and any other inconvenience that affects the operation of the equipment.

Details with noise

This is a factor that we cannot ignore when we talk about installing an electric generator, especially if it is large and you will not be able to move it as often as you would with a portable computer. If you have the advice of an engineer or architect, you can add some materials to isolate the noise produced by these machines.

Another option is to buy equipment that is soundproofed, a quality that is appreciated as it reduces the discomforts that these machines can cause to the people around them, just like animals, if we talk about a model that operates in an open space.

And if your electric generator is going to be installed in enclosed work spaces, remember to comply with the regulations established by the labor laws of that city or country.

Watch the ventilation

When an electric generator starts, it emits gases that, if not dispersed in a timely or effective way, can cause problems due to poisoning or unhealthiness. But it is not only the gases, heat is also generated that, if not spread, can create dangerous situations or definitely affect the durability of your equipment.

Hence, it is advisable to install the generator in places where air currents are abundant to eliminate any inconvenience with fuel fumes or engine heat.

It is appropriate that you verify all possible sites to install your new backup power generator and make the best decision about it, always thinking about your comfort and well-being.

Why buy a standby generator?

Automatic generators are very necessary in emergencies to ensure the full functioning of critical systems, such as fire systems, elevators in tall buildings or medical equipment for critical patients.

It is important to consider that the whole house generator of 5 to 30 KW (11kw generator, 22kw generator, 30kw generator) will supply our house during the electric shorts, but those of small loads will only give enough energy to keep some generator to power whole house appliances running (some parts of the house can be turned off).

Home emergency generators with larger loads can keep an entire house running, although it is important to consider that prices rise considerably (the standby genset generator cost $ 5,500 to $ 8,000 onwards). For more info about Standby generator see the follow link.
