What You'll Learn
The 7KW Onan generator uses 1.2 gallons of fuel per hour
The 7KW Onan generator is a popular choice for RV owners due to its impressive fuel consumption ratings and other specifications. It is also highly portable, weighing less than 20 pounds. However, it is important to note that the generator's fuel consumption will depend on various factors, such as the load and the type of fuel used. For example, the 7KW Onan generator's fuel consumption rate at no load is 0.4 gallons per hour.
Onan generators are designed specifically for RVers and travellers as they meet National Park noise requirements and most other safety requirements mandated by parks. They are also known for their durability and impressive warranties.
When choosing a generator, it is essential to consider the generator's price and fuel consumption rating. While a cheaper generator may be more affordable upfront, it will likely have a higher fuel consumption rate, resulting in higher long-term costs. On the other hand, more expensive generators tend to have better fuel consumption ratings, leading to lower fuel costs in the long run.
Additionally, the type of fuel used can also impact fuel consumption. For example, diesel generators tend to have higher fuel consumption rates and fuel costs compared to gasoline or propane generators. Therefore, it is crucial to consider the generator's fuel type when assessing its overall fuel efficiency and long-term costs.

The 5.5KW generator uses 0.9 gallons of fuel per hour
The fuel consumption of a generator depends on several factors, including the generator's size, its load, and the type of fuel used.
The fuel consumption of a generator is important to consider when purchasing one. A more expensive generator may have a better fuel consumption rating, resulting in lower fuel costs over time. Additionally, the type of fuel used can also impact fuel consumption. For example, diesel generators are generally more fuel-efficient than gasoline generators, but diesel fuel tends to be more expensive.
It is worth noting that there are no established standards or regulations governing how manufacturers measure fuel consumption for generators. As such, it is important to consider other factors besides fuel consumption when choosing a generator, such as safety requirements, durability, and warranty.
Additionally, the 5.5KW generator's fuel consumption may vary depending on other factors, such as the efficiency of the generator and the ambient temperature. Regular maintenance, such as fuel filter changes, can also impact fuel consumption by preventing issues from contaminants.

The 5500 LP generator uses propane
The Onan 5500 LP generator uses propane and has a wattage of 5500. LP stands for 'liquid propane', which is a type of fuel that offers several advantages over gasoline for portable generator applications. Firstly, propane is readily available, even during power outages when gas stations may not be operational. Secondly, LP fuel can be stored indefinitely without deterioration, which is not the case for gasoline.
The 5500 LP generator is part of the Onan 5500 line, which includes other generators with the same specifications and features, such as a super-quiet gas series, National Park Service noise level requirements, and a spark-arresting muffler. The main difference between the regular 5500 generators and the 5500 LP generator is the type of fuel they use. The 5500 LP generator uses propane, while the regular 5500 generators use gasoline.
The Onan 5500 LP generator has an average fuel consumption of 0.8 g/h of propane at half load. This is slightly higher than the fuel consumption of the regular Onan 5500 generator, which has a fuel consumption of 0.6 g/h of gasoline at half load. Despite this, the 5500 LP generator is still a cost-effective option, as propane is often cheaper than gasoline.
The 5500 LP generator is also designed with portability and ease of use in mind. It features a dolly-style handle and a low grab bar, making it easy to move and handle. The generator's enclosure protects it from dirt and debris, and can be easily removed for maintenance. Additionally, the generator's PowerDial™ integrates all the starting and operating controls into a single mechanism, making it user-friendly.
Overall, the Onan 5500 LP generator is a powerful and efficient option for those seeking a propane-powered generator. With its impressive fuel consumption ratings, portability, and ease of use, it is a popular choice for RVers and travellers who require a reliable source of power.

The 7KW generator weighs less than 20# more than the 5.5KW
The 7KW Onan generator is a viable option for RV owners, as it weighs less than 20 pounds more than the 5.5KW generator, and has the same physical dimensions. This means that it won't overpower your RV. However, there are a few things to consider when deciding between the two. Firstly, the 7KW generator may have higher fuel consumption for equal power. While the 5.5KW generator has a top-end fuel consumption of 0.9 gallons per hour, the 7KW generator consumes 1.2 gallons per hour. At no load, the 5.5KW generator consumes 0.3 gallons per hour, while the 7KW consumes 0.4 gallons per hour.
When choosing a generator, it is important to consider both the price and the fuel consumption rating. While a cheaper generator might be tempting, it will likely have a higher fuel consumption rate, which could end up costing you more in the long run. On the other hand, more expensive generators tend to have better fuel consumption ratings, so you'll save on fuel costs. The type of fuel used also affects consumption rates and prices, with diesel generators being more expensive and consuming fuel at a faster rate.
For RV owners, Onan generators are a popular choice as they meet National Park noise requirements and most other safety requirements. They are also known for their impressive fuel consumption ratings, durability, and comprehensive warranties. The Onan 5500 LP generator, for example, uses propane, which is a more cost-effective option for those who plan to use their generator frequently during dry camping.
When it comes to fuel consumption, it's worth noting that the load on the generator can vary depending on the appliances being used. This makes it difficult to determine the exact fuel consumption rate. However, a good rule of thumb is to assume half a gallon of fuel consumption per hour, although this may vary depending on the load.
Ultimately, the decision between the 7KW and 5.5KW generators depends on your specific needs and budget. While the 7KW generator offers more power, it may result in higher fuel costs. It is important to carefully consider your usage patterns and calculate the potential fuel costs before making a decision.

The 7KW generator will not overpower your RV
The 7KW Onan generator is a popular choice for RV owners due to its compact size and impressive fuel consumption ratings. While it may be tempting to opt for a more powerful generator, it is important to consider whether your RV can handle the increased load.
The 7KW Onan generator will not overpower your RV. This generator has an output of 30A at 230V, which is compatible with the standard 50A park connection. The concern about input wires being overloaded is valid, but this can be easily addressed. As long as the wiring from the generator to the transfer switch is of sufficient gauge for the output breaker on the generator, you will be fine.
If the wiring is too small, you have two options: install a breaker that trips before the ampacity of the installed wires, or replace the wires with ones that match your breaker. Replacing the wires is the recommended option, as it ensures a safe and efficient flow of energy.
The 7KW Onan generator is a good choice for RV owners who want the convenience of a generator without the worry of overloading their system. This generator has a fuel consumption rating of 1.2 gallons per hour at full load, which is impressive compared to other generators on the market.
While the initial cost of a generator may be a significant investment, it is important to consider the long-term fuel costs. More expensive generators often have better fuel consumption ratings, so you pay more upfront but less in gas over time. The 7KW Onan generator strikes a balance between power and fuel efficiency, making it a popular choice for RV owners.
