Why do I need a generator?

There are several reasons to need a generator, although they can be basically three:

  • No mains power available
  • Not enough power is available from the grid to cover the needs
  • To protect against the possibility of periodic or habitual losses of power of the electric network, that can cause in the majority of cases economic losses, and even in critical facilities like hospitals human losses.

What type of generator set do I need?

The type of generator set will vary according to the requirements of each customer. Always take into account factors such as the type of use of the generator, whether it has to run continuously or sporadically, load to be borne, location where it will be installed, weather conditions, etc. And other factors that will significantly influence the type of generator set by which to decanter.

Due to this large number of factors influencing the decision, it is always advisable to be advised by an experienced industry professional.

How do I know the power of the generator set I need to buy?

Proper selection of the power of the generator set is crucial for its correct operation. It is necessary to calculate the sum of the powers of the equipment and components to be supported by the generating set and take into account a number of corrective factors, such as starting or safety margin.

What should I take into account when installing a generator?

  • Location:
    You should think about where to install the generator, ideally to install it in an easily accessible and illuminated place to facilitate maintenance operations. For outdoor installations, it is advisable to equip the generating set with a cabin to protect it from adverse weather conditions.
  • Mounting:
    The generator sets should be mounted on level surfaces, using anti-vibration supports if necessary.
  • Ventilation and cooling:
    It is important to ensure that the generator set has sufficient ventilation to keep it refrigerated and to eliminate excess gaseous emissions and heat from the combustion of the engine.
  • Fuel System:
    You should think about the modality of fuel supply for your generator set. There are several fuel supply options, from hand pumps to fully automatic systems.

Can I connect the generator to the electrical system of my installation?

Yes, the generator sets can be connected to the home network with a transfer switch, although a qualified technician must be installed to ensure proper installation and operation.

How does a generator set work in the event of a power failure?

When there is an interruption in the electricity supply of the main network as a result of a fault or cut, the automatic transfer switch will send a signal to the generating set, which will start and send the electricity generated to the installations. When the mains supply is restored, the transfer switch will block the power output of the generator set and this function will return to the mains.

For manual switches, it is the user who performs the change from electrical to generator, and vice versa, usually by means of a lever.

How long will a generator set work with a fuel tank?

The time the generator will run will depend to a large extent on the size of the fuel tank, the consumption of the generator set and the load it has to generate. The majority of generators manufacturers design their equipment to have autonomy around eight hours, with a load around 75% of its maximum capacity. However it is possible to install larger capacity internal or external tanks to increase the number of hours considerably.

Can a backup generator run continuously?

Yes, but it is not advisable for a backup generator to operate continuously. In specific cases, reserve equipment can operate continuously for short periods of time without problems as they are designed to withstand and operate under adverse conditions, but their useful life will be reduced considerably, as they are not prepared to withstand these long periods of use.

Will the generating set make noise?

All generators emit noises due to exhaust pipe, engine and airflow. However, measures can be taken to minimize acoustic pollution from the generator set. Soundproof booths, conditioned rooms, mufflers, etc. are some clear examples.

Is it advisable to install the generator in a shed if its final location is outdoors?

No, it not is necessary since there are currently on the market a multitude of brands and models of generators that have a cabin that isolates the equipment from adverse weather conditions. However, it is advisable if it is possible to have a shed that helps to further isolate the group and also help to soundproof much of the noise it produces during its operation.

Indicate that the shed must be equipped for the correct functioning of the group, it must have sufficient ventilation to help its cooling, smoke extraction, etc.

It is advisable to consult a specialized technician if you plan to build a passenger compartment to house your generator set.

When and how should I proceed with the maintenance of my generator?

The frequency and type of maintenance required in a generator set depends on several factors, including the use of the generator set, the environment where it operates and the percentage load it supports. Frequent visual inspections should be done every two or three months to verify that everything is working properly.

A complete maintenance, with change of filters and lubricating oil, ect., It is advisable to carry out a certain number of hours, which will be specified according to the model, according to the specifications of each manufacturer. This operation must be carried out at least once a year, regardless of the number of hours of use of the generator, due to degradation of the consumables.

What does a generator set warranty cover?

As a general rule, the majority of generator sets are guaranteed for one year for generators in “Primal Power”, continuous operation, and two years in “Standby Power”, in emergency or sporadic. Although in most cases both warranty periods are limited to a maximum number of hours of operation, which varies from manufacturer to manufacturer.

Where can I get spare parts for my generator?

If you buy or own a generator you can purchase any spare parts you need at your local distributor in your area and in some cases directly from the manufacturer. Many of the parts can be compatible from one brand to another. Although it is always recommended to use manufacturer’s spare parts.
