Power outages are annoying, disruptive, and even dangerous. This is especially true in areas prone to severe weather. So, what is a backup generator, and how can it offer peace of mind during a power loss? A backup generator is a separate power system that activates automatically when your main power source goes out, keeping your family safe and your life uninterrupted.
What Is a Backup Generator: A Deep Dive
Imagine a storm knocks out your power, but your lights stay on. Your refrigerator hums, and you remain connected. Your backup generator makes this possible, providing electricity even during a natural disaster.
How Backup Generators Work
A backup generator uses a fuel type, like natural gas, propane, or diesel, to power an engine. This engine turns an alternator, generating electricity. Most homes use an automatic transfer switch. This switch monitors your main power and starts your backup power if there’s an outage. It then seamlessly returns to the utility power when it’s restored.
Types of Backup Generators
There are two main types of backup generators: portable and standby.
- Portable generators are smaller units, that power key items like refrigerators or lights during an outage. They are flexible and affordable upfront. You store them when not in use, and place them where needed during an outage.
- Standby generators are permanently installed and automatically activated during a power loss, powering essential circuits, or your entire house. Although initially pricey, they offer greater convenience and capacity.
Choosing the Right Size Generator
Choosing a generator requires careful planning based on your needs. This is why thinking about regular maintenance is important so your generator is ready at a moment’s notice. Considering a backup power source can help in inclement weather and other times you’re concerned about potential power outages.
| Generator Size (kW) | Typical Usage |
|---|---|
| 5-7 | Essential appliances (refrigerator, lights). |
| 8-12 | Additional appliances (sump pump, AC unit). |
| 15+ | Whole-home coverage, even during peak times. |
Installation and Maintenance
Backup generator installation varies. Portable units require proper hookups. Standby generators need a complex setup, often involving local permitting and a concrete pad.
When you’re using a generator, keep it outside at least 20 feet away from any doors, windows, or vents.
Maintenance also differs. Portable units involve tasks like checking oil. Standby units benefit from professional annual inspections.
Fuel Considerations
Generators offer several fuel choices.
- Natural gas is hooked directly to your home’s supply. It requires no refills and ensures continuous operation.
- Propane requires periodic tank refills. However, it’s widely available and relatively clean-burning.
- Diesel is typically used for larger units and requires special storage.
Safety Precautions
Safety with backup generators is crucial. Place portable generators far from your house to prevent carbon monoxide buildup. Never refuel a hot generator. Always follow the manufacturer’s safety guidelines for your specific generator.
Always remember to provide power safely when using extension cords. It’s important to stay informed to make good decisions during power outages.
Conclusion
A backup generator is a worthwhile investment offering protection and peace of mind. It ensures your house remains safe and functional during severe weather, natural disasters, and other unforeseen events that disrupt the power grid. It keeps your home running during an outage, especially useful for power lines in danger during bad storms.
The ideal backup power solution depends on your lifestyle, budget, house, and electrical service requirements. Carefully evaluate the size, fuel supply, safety precautions, and installation needs. By considering these factors, you can choose the best backup generator to minimize disruptions during a power loss, which may require manual transfer for some. Understanding how the transfer switch works will also give you the best setup, as you’ll need to know how the utility power connects, if a manual transfer is needed, and how the system switches into standby mode when an outage occurs.
