Things To Consider When Buying 50 Amp Generators

Choosing the perfect generator for you is not an easy task and if you are a first time buyer, the decision is even more difficult. There are some major factors which will help you choose the generator for you. Check out the following section to look at the points which will help you make the right choice.

1. Fuel Type

Most of the 50 amp generators are available in gasoline fuel type models or dual fuel type which alternates between the use of propane and gasoline. Gas models are always considered a better option even with their increasing prices but the propane run models are highly suitable for the use in RVs. But, the best option is always to go for the dual fuel opinions which enables you to use both according to your convenience.

2. Running Time

The run time of the generators range between 6 hours to 18 hours. They are suitable for RVs and home usage but it is not recommended to use them continuously. The propane-powered generators have the longest fuel shelf life and can run the longest. Your usage of the generators will affect the run time of the generator. The propane run generators will not lose the potency over time and are the most long-lasting.

3. Number of Outlets

The 50 amp generators are always equipped with different sorts of outlets varying in the power to charge the electronic appliances. Most of the generators are equipped with outlets that can power the 12 volts DC appliances or the 120 volts to 240 volts AC appliances. Some of them are also equipped with USB ports. Some of the generators have as many as four outlet varieties while some others are only equipped with two. The size of the generator also influences the capabilities when we are considering the outlets or the plugs. There are versatile products which offer different ways to use and implement it while some others allow you to connect by only plugging the cord. While selecting the number of outlets, you need to look at the ease of use.

4. Wattage

When wondering about what size of the generator is suitable for you, one must consider the total wattage required for the house or the RV to run properly. For this, you first need to consider the wattage of all the individual appliances that you need to run through the generator. Then you can choose the generator that offers wattage equal to or more than the calculated wattage. The generators are available in different wattage capacities and range from a minimum of 800 watts and go up to 500,000 watts to cater to different requirements.

5. Voltage

There are three kinds of voltage options for the generators that we are looking at. They are low voltage which range from 240 VAC to 600 VAC, medium voltage which range from 2400 VAC to 69.000 VAC and high voltage which starts from 115000 VAC to 1100000 VAC. The low voltage generators are most suited for home and RV use.

6. Tank Volume

There are several different kinds of generators with different fuel tank sizes. In case of power outages for small durations, a small fuel size of the generators is sufficient. On the flip side, the larger fuel tank generators are more suitable for powering larger establishments for longer periods. So, the usage of the generators will influence your decision of selecting the tank volume of the generators.

7. Warranty

It is not every day that you invest in a generator, therefore it is better to go for a generator that is durable and long-lasting. A foolproof way to select the generators based on the durability is by checking the warranty that is offered by the brands. The brands which offer better warranty are sure to provide products that are more durable and last for a longer time.
