What Are the Top Considerations When Choosing the Right Generator for Outages?
When choosing the right generator for outages, the top considerations include power needs, fuel type, runtime, portability, noise level, and safety features.
- Power Needs
- Fuel Type
- Runtime
- Portability
- Noise Level
- Safety Features
The selection process involves evaluating each consideration in detail.
-
Power Needs: Understanding your power needs is critical when selecting a generator. Power needs refer to the total wattage required to run essential appliances during an outage. Homeowners should calculate the starting and running watts of appliances such as refrigerators, lights, and medical equipment. The U.S. Department of Energy recommends determining total wattage requirements using a wattage calculator to avoid an undersized generator.
-
Fuel Type: The fuel type impacts the generator’s operation and efficiency. Common fuel types include gasoline, diesel, propane, and natural gas. Gasoline generators are widely available and typically less expensive upfront but have shorter shelf lives. Diesel generators often provide longer run times and durability. Propane generators, though cleaner burning, require storage tanks. Each fuel type comes with advantages and disadvantages influenced by availability, efficiency, and maintenance.
-
Runtime: The runtime of a generator is a critical factor in its usability during extended outages. Runtime refers to how long a generator can operate before needing to refuel. Typically measured in hours at a designated load, runtime is crucial for continuous power supply. For example, a generator with a runtime of 8 hours at half load will provide sufficient power overnight without refueling.
-
Portability: Portability assesses how easily a generator can be moved and transported. Generators vary in weight and design. Smaller, lightweight models may be suitable for camping or outdoor events, while larger generators may require sturdy wheels and frames for mobility. Consideration of portability is essential for users who need to relocate their generator frequently or position it away from their home for safety.
-
Noise Level: Noise level is an important consideration because some generators can be quite loud and disruptive during operation. Noise is typically measured in decibels (dB), and many homeowners prefer models with lower decibel ratings for residential use. The Quietmark provides ratings for quieter generators, helping consumers choose models that minimize noise pollution.
-
Safety Features: Safety features contribute to the safe operation of a generator. Key safety features include automatic shut-off mechanisms, carbon monoxide detectors, and overload protection. According to the Consumer Product Safety Commission (CPSC), safety features help prevent accidents, like CO poisoning, which has caused numerous fatalities related to improper generator use. Generators equipped with these safety features help ensure safer environments during outages.
Selecting the right generator involves weighing these considerations based on your specific needs, situation, and preferences.
