Criteria for choosing the optimal generator

To select the optimal generator that will become a reliable source of autonomous power supply, it is necessary to clearly determine purpose of its use. This can be either a backup power supply for a small country house or an emergency power supply for an office space. In the latter case, you will have to take a closer look at gas generators for continuous operation.

The distinctive features of the equipment used to supply power to various facilities are clearly presented in the following photo selection.

Depending on the purpose of use, the main characteristics that the electric generator must have will differ.

The main parameters influencing the choice of electricity generator are:

  • power;
  • installation location;
  • fuel type;
  • launch type;
  • additional functions;
  • manufacturer's reliability.

Next, we will consider these criteria and their features in more detail.

Criterion #1 - power selection

When purchasing a household gas-powered generator to generate electricity, it is important to choose the right power. It should be enough to serve the main consumers.

Therefore, when calculating, you should sum up the power of electrical appliances, which first of all need to be provided with backup power supply in the event of a centralized power outage. For example, a pumping station, a refrigerator, a boiler, light bulbs. And such consumers as a washing machine, dishwasher, TV or computer, iron are secondary - i.e. You can do without them for some time.

Electrical supply for a private home
If your electricity is turned off regularly and for a long time, and you want to provide yourself and your family with maximum comfort, then devices that are of secondary importance should also be taken into account when calculating the generator power

The power parameter of a specific electrical appliance for calculations should be taken from its passport. And don't forget about the starting current - some equipment requires several times more electricity to start than to operate.

Below we suggest that you familiarize yourself with the table of power and starting current of the main household electrical appliances.

Starting current coefficients
A number of equipment require two or even three times more electricity to start than later for operation (pump, air conditioner, refrigerator, microwave). Therefore, some manufacturers emphasize that their generators are designed for short-term loads that are 20% higher than their rated power

Having added up the power of all the devices that you will use during a power outage, you need to add 15-20% of the reserve - the generator should not work at the limit of its capabilities. The resulting number will be the optimal power of your electric generator.

As the experience of numerous buyers shows, for backup power supply to a small home, equipment with a capacity of 5 kW is most often purchased. There is enough power here to service a gas boiler, well, or boiler.

Criterion #2 - installation location

The installation location is also one of the important criteria when choosing equipment. Initially, you should decide on the location of the future installation - on the street or V indoors.

Outdoor models, as a rule, are equipped with a protective casing that can withstand exposure to sunlight, gusts of wind, and prevents precipitation.

Some models without a container can also, according to the manufacturer’s recommendations, be installed outdoors. But they need to be protected from rain, snow, wind and other atmospheric phenomena.

Generator under a canopy
When installing an electric generator outdoors, many owners assemble a homemade container or make a canopy to protect the equipment from excess moisture, dust and mechanical damage.

Criterion #3 - fuel type

Equipment for autonomous power supply varies according to the type of fuel used to generate electricity.

Generators are:

  • gasoline;
  • diesel;
  • gas;
  • hybrid.

Hybrids can use gasoline or gas to operate (liquefied or mainline). To change the type of fuel, you need to follow the manufacturer's instructions.

We will look at the features of electric generators using different types of fuel in detail in the next gallery.

Criterion #4 - launch type

Another criterion for choosing an electric generator is the type of start-up.

Generators start up:

  • manual;
  • electric start;
  • remote;
  • auto.

Many models have two types of start – most often manual and electric start.

The most convenient option is automation, which allows you to practically eliminate the presence of a person - the system will automatically start and turn off when the centralized power supply is turned off and on. But such equipment is more expensive.

Next, we will consider the features of each type of launch in the following photo selection.

Criterion #5 - additional features

In addition to the main functions, additional functions are also important for comfortable operation of the equipment. One of these is heating oil filter and generator. This is an important option if you plan to use the generator in the cold season at sub-zero temperatures. But a number of manufacturers offer a heating kit for an additional fee.

Also important for many users number of sockets, Availability power And 12V output. The latter is of interest to buyers for charging car batteries and other electricity consumers.

A 32A power outlet is needed if you plan to connect powerful electrical equipment. And not all models have it.

Connecting the welding machine to the generator
Conventional household generator models are not designed to connect a welding machine. Therefore, if you plan to work with welding often and for a long time, then you should take a closer look at specialized generators

For ease of use, the presence of protective casing – models with a container can be placed both outdoors and indoors.

Another point to pay attention to when choosing is winding generator It could be copper or aluminum. Copper is more expensive and has a longer service life.

Criterion #6 - manufacturer reliability

Products from a well-known brand are more expensive – this rule is also true for generators. But the manufacturer’s reputation guarantees that the equipment will meet the stated characteristics and will work as expected (and even more).

But it’s better not to buy cheap Chinese generators of an unknown brand - they will not fulfill their warranty period. And it often happens that instead of the copper winding indicated in the passport, they have a copper-painted winding, and the actual power is almost half less than the declared one.

Reliable manufacturers of gas generators include brands such as GENERAC (American company Generac Power Systems), BRIGGS & STRATTON (American company of the same name), Russian Engineering Group (RusInzhGroup company), Comfort GAZ (Russian company GARANT LLC), Grandvolt (Hydrokinetics LLC, representative of ESPA GROUP (Spain)).

Generator with protective casing
Some manufacturers have models with dust-moisture-proof and noise-proof containers. But the air cooling system is carefully thought out. If you assemble a protective container yourself, you should definitely take care of heat removal

You should also check before purchasing availability of a service center specific manufacturer in your city, town or region. This is needed in case the generator breaks down.

Recommendations for using a gas generator

The gas generator can be installed both indoors and outdoors. If the first option is chosen, then the same standards apply as for installing a boiler, water heater, stove and any other gas-using equipment - you must select a room with an area of ​​at least 15 m3, correctly connect the equipment and install gas leak sensor.

Regardless of what gas will be used (liquefied or main gas), before operation it is important to pay attention to ensure that there is an influx of fresh air and removal of exhaust gases. Generator manufacturers also warn about this. That is, it is important to ensure effective forced ventilation, as well as for gas boiler.

The gas generator is installed on the street
Installing a generator outdoors is a better solution. This way the gas will evaporate freely in case of any leaks. The sound of a running engine is also equally important. Therefore, it is better to install it outside. Although it is quiet, the noise can still disturb you

If you plan to connect the device to the main gas, then you will need to coordinate your actions with the gas supplier and obtain special permission, as for connecting any gas-using equipment.

For this purpose, you will need to provide a certificate of purchase of a gas generator, its registration certificate and a certificate of conformity. In case of a positive decision, install on the gas pipeline gas tap for fuel supply. And only a gas service employee with special permission has the right to do this. Be prepared that you will have to pay for the work to connect the gas generator.

You can also immediately conclude maintenance contract gas equipment. After all, a number of models require maintenance every 100 operating hours.
