4. Generator Size: How to Choose the Right One
Generator size is crucial in ensuring that you have enough power without wasting energy. While it’s important to match the generator’s wattage to your needs, you also want to think about future power requirements.
Sizing Your Generator
To choose the right generator size, consider these factors:
Power requirements: List all the items you want to power during an outage, as mentioned earlier.
Surge capacity: Make sure the generator can handle the surge wattage for appliances with motors.
Future needs: Consider whether your power needs may increase over time. It’s better to choose a slightly larger generator now than to upgrade in the future.
Choosing Between Gas and Propane Models
Gasoline and propane models both have their advantages, but you need to pick one based on your location and preferences.
Gasoline is convenient if you already have a supply, but it can be costly and harder to store.
Propane offers longer fuel shelf life and cleaner burning but requires you to have a propane tank.
5. Noise Levels: Consider Quiet Operation
Noise can be a significant concern with some generators. Portable generators, in particular, can be quite loud, which can disrupt your sleep or your peace.
Sound Ratings
When shopping for a generator, check the decibel (dB) rating. Inverter generators tend to be quieter, often producing noise levels between 50 to 60 dB, comparable to normal conversation levels.
Noise Reduction Features
Some generators come with soundproof enclosures or mufflers to reduce noise. Look for these features if you want a quieter operation.
6. Portability: Consider Weight and Mobility
If you need to move the generator around, portability becomes an essential factor. Smaller portable generators are typically easy to move, but larger standby generators are heavy and require professional installation.
Wheeled Generators
Many portable generators come with wheels to make transportation easier. If mobility is important, look for a generator with sturdy wheels and handles for better maneuverability.
Lightweight Models
If you need something light and compact, opt for inverter generators, which are typically lighter and more portable than traditional gasoline generators.
7. Generator Features: What to Look For
While the power output and fuel type are the most critical factors, there are additional features you can consider to enhance the generator’s efficiency and convenience.
Automatic Start
Some standby generators come with an automatic start feature, which allows them to turn on without any input from you during a power outage. This is a convenient feature if you want peace of mind that the generator will start up when needed.
