How do I choose the right generator for my home?
Assessing your power requirements
In estimating my power, I attempt to add the total wattage essential to operate the appliances and devices during an outage. This is inclusive of both the starting (surge) wattage and the running wattage of each item. Let us take a sample refrigerator, so it will have 1200 watts for startup but 200 watts to run the system. Some of the items I consider are lighting, heating or cooling devices, communication devices, and even medical appliances.
- Running Wattage: This value indicates the total wattage essential to run a device throughout the day. A wide range of household appliances should have this value that is specified either in the product label or its manual.
- Starting Wattage (applicable to specific devices): Several household items, including refrigerators and air conditioners, will draw more power than usual when they are turned on. This is something I make sure my generator can deal with.
- Total Wattage: By calculating the running wattage of appliances that I desire to power simultaneously, I can establish the required baseline. The appliances with surge wattage will require added considerations, therefore, I account for them too.
Combining this information allows me to find a generator that has a 10-20% greater power output than what I calculated. This prevents overloading and facilitates stable operation.
Fuel options: Gas, propane, or dual-fuel generators
In case of choosing fuels for my selection, I consider gas, propane, and dual fuel generators, looking at their peculiar features and technical advantages:
- Gasoline Generators: These are usually purchasable from many places at a cheaper price than competitors. Gasoline burns efficiently while offering astonishing output. Gas has a shorter shelf life (about 3-6 months untreated) plus gas can be scarce during emergencies. Also, gas emits higher emissions than its competitors.
- Propane Generators: In comparison with gas, propane burns cleaner and offers a longer shelf life (indefinite when stored properly in pressurized tanks). On the downside, propane generators typically have slightly less energy output (around 10-15% lower efficiency) than gasoline models plus, they are dependent on having stocked propane tanks and fittings.
- Dual Fuel Generators: Clean energy: storage convenience. Higher immediate output: heat energy. With these options, I can decide what fuel to choose and generators of this type are sold at higher prices than regular propane and gas models. Why do they justify the price? Because of the diversity of dual-fuel generators. These provide flexibility on which fuel to use, allowing users to choose propane or gasoline.
The crux of my decision rests on managing energy demand, fuel supply, and long-term storage. For instance, if independent operation from the grid is crucial along with storage longevity, my requirements would be met with a dual-fuel generator that runs on propane.
