What Size Backup Inverter Generator Do You Need for Your Home?
When considering the best home backup inverter generator, it’s essential to evaluate your home’s power needs to choose the appropriate size.
- Wattage Requirements: Calculate the total wattage of the appliances and devices you want to power during an outage.
- Starting vs. Running Watts: Understand the difference between starting watts (the initial surge needed to start a device) and running watts (the continuous power required to keep it running).
- Generator Capacity: Choose a generator that not only meets your immediate wattage needs but also has a margin for additional devices or future requirements.
- Portability and Fuel Type: Consider whether you need a portable generator for flexibility or a stationary one for more power, as well as the type of fuel (gasoline, propane, or dual-fuel) that best suits your needs.
- Noise Level: Evaluate the noise output of the generator, especially if you live in a residential area where quiet operation is preferred during outages.
Wattage requirements are crucial as they determine the size of the generator you’ll need. Make a list of all essential appliances, such as refrigerators, freezers, and heating or cooling systems, and sum their wattage to find out the minimum generator capacity required.
Starting vs. running watts is an important distinction because many appliances require more power to start than to run. For example, a refrigerator might need 1,200 watts to start but only 800 watts to run, so it’s vital to account for these surges in your calculations.
Generator capacity should ideally exceed your calculated needs by about 20-30% to allow for unforeseen electrical demands or future power needs. This extra capacity can prevent the generator from being overworked and prolong its lifespan.
Portability and fuel type are significant factors in your decision-making process. If you need to move your generator around, a lightweight, portable model may be best, while stationary units often provide more power but require a more permanent setup. Additionally, consider the availability and cost of fuel types in your area.
Noise level is also an essential consideration, particularly for residential use. Generators can vary significantly in decibel levels, and quieter models are often more desirable in neighborhoods to avoid disturbing neighbors during power outages.
