6 Things To Consider When You Know You Need An Electricity Generator

An electric generator is a good solution for those who live in areas where there are often failures in the supply of electricity or large fluctuations and, having a wide range of models, you must make an efficient documentation before purchasing it. 


There are several aspects to keep in mind when you want to buy an electric generator, in order not to make an expensive investment that is not necessary and to size it according to your needs. Thus, below, we offer you a list that is good to keep in mind, in order to choose the best electric generator for you.


What you need:

Depending on how much and where you want to use it, you can choose: 

Stationary electric generator for major use – this being ideal for holiday homes or more isolated areas where you need high power, the price is also high, it can power several appliances for a longer period of time, 16 – 24 hours , is installed by a specialist. 

Moderate stationary electric generator – it is recommended to supplement the electricity supply in areas where there are frequent interruptions, it is mounted stationary, it is a more convenient solution at the price, it ensures the supply of only a few appliances and a continuous operation of 8 – 10 hours.

Portable electric generator – has a more convenient price than previous models, is suitable for camping or caravan holidays, moves easily, you can only power certain appliances for a short period of time. The better models are powered by gasoline, but require the presence of a voltage stabilizer, other models can be powered by propane or gas.


Voltage and power generated:

These are particularly important features. 

The voltage generated must comply with the requirements of the equipment you want to connect, thus having single-phase models – in general, household appliances and DIY appliances operate at 230 V; and three-phase – for powerful engines in general industrial or professional. 

The power generated must be calculated so that the device can take over the equipment that is of interest to you during a power outage, the power of the generator must be greater than the sum of the power consumed simultaneously by the device. There are three classes for generators, namely: low power (500W – 2200 W) for portable models in general; medium power (2200W – 5500W) and high power (up to 10000W). 

For inductive appliances (which need more power at start-up) such as: refrigerator, washing machine, air conditioning, neon lights, etc. you need a powerful electric generator (between 7000W – 10000W); for resistive ones such as TV, radio, electric oven, electric hob, etc. an average power generator (3000W – 5000W) is also sufficient. 


What fuel do you use:

They are generally based on diesel or gasoline. Diesel ones are stronger and more expensive, they start faster, they are noisier, they are reliable. The ones on gasoline are cheaper than the ones on diesel, quieter, they are generally smaller, but they have a lower efficiency. 

Important here is the capacity of the fuel tank, in case you use it frequently you need a larger capacity so that you do not have to refuel it. 



Quality of current generated:

You can choose models that come ready equipped with electronic speed regulator that ensures a good quality of the supplied current, but have a higher price. If you opt for models with mechanical regulator, then you need voltage stabilizers (here the comparative list) to protect the electronic equipment. 

You will choose a voltage stabilizer according to your needs: with a transformer for small consumers or with a servomotor for the strong ones; correlating its capacity with that of the generator; with protection for short circuit or overload etc.


Boot system:

And here you have several options: twine, turnkey and automatic. 

Starting the rope is most often found with cheaper generators and is done in the same way as with other devices such as chainsaw, boat, cultivator, etc. If you are not used to it and you do not think that you have the necessary force to start the generator, choose another model, because if you miss the start several times, you risk damaging the device. 

Turnkey starting is a simple and easy to use procedure, having the same principle as starting a car. 

Automatic start is recommended for stationary models because the generator starts itself in case of power failure. It is a very useful facility to not have to go to start it manually in case of a power failure, it will also start even if you are not at home and so you are calm that you will not run out of heat in winter, it is not will spoil the food in the refrigerator in summer, the air conditioning will work, etc.


Other facilities:

There are other aspects that are of interest, namely:

Sockets: some models also included sockets for emergencies.

Wheels: Whether it is a portable model or a stationary one, wheels are needed to be able to move it without the need for additional help.

Housing type: in case you want to mount the generator outside, you must be careful with the type of housing chosen, in order to be resistant to the action of UV rays, humidity, rain or snow, extreme temperatures. They can also be equipped with sound protection, high resistance to mechanical shocks, etc.

Battery: in case you need a portable model that starts automatically, go for a model equipped with a battery that provides this function. The cost will be higher but it gives you an easy and effortless start.

Fault detection system: it is a function present only on more modern models that automatically checks certain parameters and you can choose to be informed by SMS or e-mail in case of detection of defects that need to be remedied.
