When considering the purchase of a generator to secure your power supply, understanding the differences between automatic and portable models is crucial to making an informed choice. Both types of generator offer a variety of backup solutions, each with its own distinct advantages and disadvantages, suited to different needs and situations.

Define primary use 

To start thinking about purchasing a generator, it's essential to ask yourself a few key questions to determine which model will best meet your specific needs. First of all, what is the main use you envisage for your generator? Are you planning to guarantee the power supply to your home or cottage in the event of a power cut, or are you looking for a mobile solution to accompany your outdoor activities and various projects?

The nature of your current electrical installation should also be considered. Do you have equipment requiring a fixed, permanent connection, such as a heating system, well pump or air conditioner? These factors have a major influence on the choice between an automatic generator, which connects directly to your electrical system, and a portable generator, more suited to occasional, mobile use.

The sensitivity of the devices you wish to power is also an important criterion. Computers, electronics and other delicate equipment often require a stable, clean power source to avoid power surges and interruptions, which may direct your choice towards models specifically designed for these needs.

Finally, convenience of use is also an important factor. For example, a generator that starts automatically in the event of a power failure can be crucial to maintaining comfort and safety without manual intervention, especially in areas prone to frequent power cuts. Don't forget to assess the power required, expressed in watts, to ensure sufficient power for your requirements. These initial questions will guide you towards the most suitable choice between an automatic generator and a portable version, highlighting the advantages and limitations of each according to your particular situation.

The advantages of the automatic generator 

Automatic generators offer considerable advantages, specially designed to guarantee peace of mind in the event of a power cut. One of their major assets is their ability to start up automatically, often within seconds of detecting a power failure, ensuring electrical continuity without manual intervention. Unlike portable models, they do not require refueling or complicated connections with extension cords, eliminating the need for prior preparation in an emergency situation.

What's more, many automatic generator models incorporate remote monitoring capabilities, enabling users to control them and check their status via mobile apps, which is particularly useful when away from home. This feature ensures efficient, proactive management of backup power. 

Finally, designed to withstand the elements, these generators guarantee consistent reliability and performance, even in adverse weather conditions. This robust assembly ensures that the power supply remains stable and safe, whatever the weather, underlining their superiority over portable options that may require additional shelter or special precautions.

Disadvantages of the automatic generator 

While automatic generators offer a series of undeniable advantages, they also have a few drawbacks to consider. Firstly, the initial cost of an automatic generator is generally higher than that of portable models. However, this investment can be justified by the added value to your home. 

In fact, installing such a generator can increase the market value of your property, as well as allowing you to continue your daily activities uninterrupted during a power outage, saving you from lost productivity and food spoilage.

Another point to consider is the need for professional installation. These systems must be properly integrated into your existing electrical installation, which requires the intervention of qualified electricians. 

Fortunately, companies like Erco offer high-quality, professional service, ensuring that your generator is installed safely and efficiently. By choosing recognized experts, you ensure not only the reliability of your installation, but also compliance with current safety standards.

The advantages of portable generators

Portable generator

Portable generators offer several advantages that make them attractive to many users. Firstly, they are easy to start up and move around. Lightweight and designed to be mobile, they can be quickly moved and positioned wherever the need arises, whether around the home or on an outdoor site.

What's more, these generators provide a convenient power source for a variety of household appliances or tools, making them indispensable during outdoor activities such as camping, or on building sites where access to electricity is limited. They can power everything from portable fridges to drills, ensuring that you always have the energy you need for your tasks or comfort.

Finally, the cost of a portable generator is significantly lower than that of an automatic standby generator. This price difference makes them particularly attractive for those looking for a cost-effective emergency power solution, or for those who only need backup power occasionally. In short, portable generators offer the flexibility and affordability that can suit less demanding budgets and needs.

Disadvantages of the portable generator

Despite their advantages, portable generators have a number of disadvantages that can be prohibitive for some users. One notable disadvantage is that they do not restart automatically in the event of a power failure. This requires manual intervention to restore power, which can be problematic when a failure occurs in the absence of the home's occupants.

Portable generators also require regular refueling. This means not only having a reserve of fuel, often in large quantities depending on the frequency and duration of use, but also managing the storage of this fuel safely. This can be both a logistical challenge and a potential risk.

Another disadvantage is their inability to be left outdoors for long periods, especially in adverse weather conditions. They therefore require shelter or protection from the elements, which can limit their usefulness in certain situations and necessitate additional storage arrangements.

In terms of power, portable generators also offer limited capacity compared to automatic models. They may not be sufficient to power an entire house or large appliances on a continuous basis. What's more, for those less comfortable with technology or manual handling, managing a portable generator can be complex and daunting. All these factors need to be taken into account when evaluating generator options to meet specific electrical backup needs.
