Besoins en énergie

Calculer la puissance

Vous devez savoir quelle puissance vous utilisez avant d'acheter un générateur. Vous éviterez ainsi d'acheter un générateur trop faible ou trop puissant. En vérifiant vos besoins en électricité, vous assurez la sécurité et le bon fonctionnement de votre groupe électrogène. Des groupes comme le NERC et la FERC affirment que les propriétaires doivent vérifier les modèles de leurs générateurs.. Ils veulent s'assurer que le générateur fonctionne comme il se doit. Ces règles montrent qu'il n'est pas seulement intelligent de vérifier ses besoins en électricité, mais que cela est nécessaire pour la sécurité et la fiabilité.

Pour connaître vos besoins en watts, vous pouvez essayer différentes méthodes :

1. Utilisez une pince ampèremétrique pour connaître votre consommation la plus élevée. Additionnez les ampères de tous les panneaux pour obtenir le total.

2. Vérifiez vos factures d'électricité. Recherchez le pic le plus élevé de l'année écoulée. Ajouter 25% pour couvrir les besoins supplémentaires.

3. Pour les entreprises, utilisez des règles simples. Les bureaux ont souvent besoin de 5 watts par pied carré plus 50 kW. Les magasins peuvent avoir besoin de 10 watts par pied carré plus 50 kW.

4. Gardez toujours différence entre les puissances de démarrage et de fonctionnement. Certaines machines ont besoin de plus de puissance pour démarrer que pour fonctionner.

5. Utilisez des calculateurs de puissance en ligne pour passer du kW au kVA en passant par les ampères et les volts.

Conseil : Ajoutez toujours environ 25% à votre puissance totale. Ce supplément permet à votre groupe électrogène de faire face à des hausses soudaines de puissance.

Taille du générateur d'allumettes

Une fois que vous connaissez votre puissance totale en watts, choisissez la bonne taille de générateur. Choisissez un groupe électrogène qui répond à vos besoins ou qui les dépasse légèrement. Si votre groupe électrogène est trop petit, il risque de surcharger et de s'arrêter. S'il est trop grand, vous risquez de gaspiller du carburant et de l'argent.

• Pour les maisons, dressez la liste de tous les appareils et dispositifs importants. Additionnez leurs puissances de démarrage et de fonctionnement.

• Pour les entreprises, utilisez la superficie et les listes d'équipements pour évaluer les besoins.

• Assurez-vous que votre groupe électrogène correspond à la phase et à la tension de votre réseau.

Un groupe électrogène de bonne taille vous permet de garder vos lumières allumées et vos biens en sécurité. Elle permet également à votre générateur de durer plus longtemps et de mieux fonctionner.

• Pick standby generators for whole-home or business backup.

• Try solar generators for green, low-power needs.

Liquid-cooled models are best for big places with high power needs. Air-cooled models work for smaller homes or light business use. Always pick the generator type that matches your power needs and plans.

Key Features

Safety

When picking a generator, always check for safety features. Many quality generators have carbon monoxide (CO) shutoff sensors. These sensors turn off the generator if CO gets too high. This keeps you safe from harmful fumes. Low-oil shutoff stops the engine when oil is low. This protects the engine from damage. Electric start helps you turn on the generator fast. It is helpful during emergencies. Transfer switches let you connect the generator to your home safely. You do not need to use extension cords. Some models have smart monitoring. This lets you watch how the generator works and find problems early.

Conseil : Always use your generator outside and far from windows. This stops CO from building up inside.

Durability

A strong generator lasts longer and saves money over time. Companies test generators to see how long they can run. Experts use the WIDIPRO® process to check insulation aging. This helps them guess how much life is left in the parts. Regular checks and care help some generators last over 50 years. The table below shows how experts study and help generators last longer:

Aspect	Summary
Diagnostic Method	WIDIPRO® process tracks insulation aging and predicts lifespan
Lifespan Case Study	Two hydro generators ran 36–53 years with regular checks
Aging Factors	Heat, electricity, environment, and movement affect aging
Lifetime Prediction	Uses measurements, not just visual checks, for better planning
Maintenance Implication	Regular checks help you fix problems early and avoid breakdowns

Niveau de bruit

Noise is important if you use your generator at home. Some generators are very loud. Others are much quieter. The engine, cooling fan, and exhaust make most of the noise. Loud generators can be as loud as a chainsaw. You can make them quieter with barriers, insulation, or better mufflers. The table below shows where noise comes from and how to lower it:

Noise Source	Noise Level (dB)	How to Reduce Noise
Engine	100–121	Use barriers or insulation
Cooling Fan	100–105	Add sound-absorbing materials
Exhaust (no silencer)	120–130	Install larger mufflers

For less noise, pick inverter generators or models with soundproofing.

Run Time

Run time means how long a generator works before refueling. Efficient generators use less fuel and last longer. Diesel generators often run 20 to 30 hours on one tank. Gasoline models usually last 8 to 14 hours. Inverter generators can run 8 to 10 hours. They may last longer if you use less power. Standby generators with natural gas can run for days without stopping. Longer run times mean fewer stops and more steady power.

• Standby generators: 24 hours to several hundred hours (with natural gas)

• Portable generators: 8–20 hours (depends on tank size and load)

• Diesel generators: 20–30 hours (high efficiency)

• Propane generators: 10–20 hours (cleaner emissions)

Picking a generator with a long run time helps you stay powered during long outages and saves fuel.

Options de carburant

Picking the right fuel for your generator is important. It changes how much you spend and how well it works. Each fuel type has good and bad points. Here is what you should know:

Essence

Gasoline generators are very common. You can get gasoline at most gas stations. These generators are good for short or emergency use. Gasoline engines start fast, even when it is cold. But gasoline does not last long in storage. It can go bad after a few months. Gasoline generators are often louder than other types. They also make more pollution. If you use your generator a lot, you may pay more for fuel.

• Gasoline is easy to find and refill.

• Works well for small and portable generators.

• Gasoline lasts about 3 to 6 months.

• Makes more noise and emissions.

Propane

Propane is a cleaner fuel choice. You can keep propane for years without it going bad. Propane engines make less carbon monoxide and smog. They also cost less to take care of. The exhaust from propane has little smell or smoke. But propane has less energy, so you might need to refill more often.

Metric	Propane Advantage Compared to Diesel/Gasoline
CO Emissions	60% lower than gasoline
NOx Emissions	20% lower than gasoline
Smog-Producing Hydrocarbons	80% lower than diesel
Shelf Life	Indefinite
Maintenance Cost	About 40% less than diesel

Propane is a good pick if you want clean power and easy storage.

Diesel

Diesel generators are strong and last a long time. They can work for many years if you take care of them. Diesel engines can handle heavy use and run for a long time. They use fuel better than gasoline or propane. Diesel fuel is not easy to catch on fire, so it is safer for some jobs. New diesel generators meet tough rules for pollution. But they can be heavy and loud.

Feature	Diesel Generators
Lifespan	Decades with maintenance
Efficiency	High fuel economy
Fiabilité	Excellent for critical backup
Maintenance	Low, but regular checks needed
Drawbacks	Heavy, noisy, fuel degrades after 1 year

Gaz naturel

Natural gas generators hook up to your home’s gas line. You do not have to store fuel. These generators are quiet and make less pollution. They start easily in cold weather and work well for long outages. The fuel supply is steady if the pipes work. Natural gas is often cheaper than gasoline or diesel if you use it a lot.

• Cleanest burning fossil fuel.

• Steady supply through pipelines.

• Less noise and fewer emissions.

• No need to store fuel.

Many generators can use two fuels. This lets you switch fuels to save money. Always check what fuels are easy to get in your area before you choose.
