Factors To Consider When Choosing The Best Dual Fuel Generators
You have come across our list of the best dual-fuel generators on the market. Now, we will guide you in choosing the ideal option among those generators that meet your needs. The selection process involves careful consideration of various key factors that ensure your choice suits perfectly for your power requirements.
Let’s get into the details of key factors to be considered when purchasing a dual-fuel generator…
1. Power Output
The power output of a dual-fuel generator is vital, as it tells us how much electricity it can provide to support a wide range of devices and appliances. This output is usually measured in watts. Simply, the higher the power output, the more devices it can run simultaneously. Ensure to match the total power requirements of your connected devices with the generator’s power output to avoid any damage to the electronics or generator itself. These generators offer power outputs that range from 1000 to 10,000 watts.
For example, a generator providing a power output of 3000 to 5000 watts is enough for basic household use, including running a refrigerator, lights, or a microwave. Whereas, a generator offering a power output of 7000 watts or more is required for more extensive use, including running multiple large appliances or heavy power tools.
2. Fuel Consumption
How efficiently the fuel is consumed by the generator will play a major role in its maintenance, as it impacts the overall operational costs and runtime. Usually, generators with higher fuel efficiency offer longer runtime with less fuel consumption, making it more economical over time. Also, remember that the consumption of fuel varies based on the type of fuel used in the generator. For instance, a mid-range 5000-watt generator consumes around 0.75 gallons of fuel per hour on a full load of gasoline, which varies depending on the load and fuel type. Some advanced models have “Eco Mode” or similar fuel-saving features that enhance fuel efficiency and extend the usage time without any need for frequent refueling.
3. Fuel Tank Capacity
The fuel tank capacity of a generator will directly influence its runtime. Usually, dual-fuel generators run on both propane and gasoline and have separate fuel tanks to store the fuel. A generator with smaller tanks needs frequent refilling, particularly if running on high loads, whereas larger tanks have less often refueling and provide steady power supporting extended operation. Even though the fuel tank sizes of the generators vary, they are usually measured in gallons. The tank sizes will range from 3 gallons in portable models to over 8 gallons in higher-capacity units. For example, a 5000-watt generator with a 6-gallon tank will run for 8 – 10 hours at 50% load on gasoline.
4. Noise Levels
Generals are noisier and thus necessitate checking the noise levels before the purchase. This is more critical in residential areas or during camping where the lower noise levels are better. The decibels (dB) define the noise level. Operating sounds of the generator range from 50dB (similar to conversation sound) to over 85dB (similar to traffic noise). Some advanced models are equipped with sound-dampening technologies like enclosures (or) noise-reducing features including mufflers, or insulation to reduce operational noise. One must always prefer dual-fuel generators with low dB ratings but should balance power and comfort. It should be quieter and suitable for noise-sensitive environments.
5. Portability
Portability is an important factor when it is necessary to move a generator from location to location or between settings. Some of the features that promote portability include lightweight designs, wheels, and handles. Generally speaking, portable generators weigh anywhere from 50 to 250 pounds and include durable wheels and fold-down handles that are easy to transport. This simplifies maneuverability, especially across rough terrain.
6. Fuel Type And Engine Type
As indicated earlier, since dual-fuel generators can run either on propane or gasoline, you have some flexibility in selecting the fuel type for your generator, depending on the availability of the fuel and cost in your area. Usually, gasoline is cheap and readily available for short-term use, while propane burns cleaner for longer storage. Besides, you have other considerations such as environmental impact, safety, and storage needs.
The type of engine that a dual-fuel generator will impact its operation and runtime/life. There are two general types of engines in this generator type. The recoil-start engine and electric-start engine are the two main types of engines. A recoil-start engine is a basic and reliable version and offers good performance in harsh conditions like extreme temperatures or high altitudes. The electric start engine is a more sophisticated and adaptable version that will easily start using a push button and works well under all conditions.
7. Safety Features
One has to check the safety features when purchasing these dual-fuel generators to prevent accidents and use them safely. Check out some of the safety features:
- Automatic Low Oil Shutoff will turn off the generator automatically to protect the engine from any damage caused due to the low oil levels.
- Overload Protection safeguards both the generator and connected devices/appliances from getting damaged due to their power overload.
- Carbon Monoxide (CO) Auto-Shutoff is an advanced feature found in new models that are equipped with sensors. It auto-turns off the generator whenever it detects dangerous levels of CO. Thus, it enhances safety and eco-friendliness during operation.
FAQs:
The worthiness of dual fuel systems depends on factors like local energy costs, climate, and environmental priorities. They offer flexibility to switch between a traditional heating system and an alternative source, potentially saving costs. Consider upfront expenses, long-term savings, and government incentives to determine if a dual fuel system aligns with your needs and budget.
The superiority of a dual fuel generator over a diesel generator depends on specific needs. Dual fuel generators offer flexibility by running on both gas and propane, providing fuel options. Diesel generators are often more fuel-efficient and durable, suitable for long-term or heavy-duty use. Consider factors like fuel availability, cost, and intended use to determine which generator aligns better with your requirements.
At an average consumption rate of 2 to 3 gallons per hour, a 1,000-gallon propane tank has the capacity to power a generator for approximately 200 (equivalent to 8.3 days) to 400 hours (equivalent to 16.7 days).
Yes, it is possible to convert some generators to dual fuel operation. Conversion kits are available in the market for certain generator models, allowing you to modify them to run on both gasoline and propane or natural gas.
Conclusion
Dual fuel generators are great for many needs. They work with both gasoline and propane. We looked at many kinds, like portable, high-power, and inverter models. Here are some of the best:
- Westinghouse Dual Fuel Generator – This one is very powerful and lasts a long time.
- Duromax Dual Fuel Generator – It’s very flexible and strong.
