Buying Guide: Choosing A Perfect Dual Fuel Generator

Dual fuel generators really are unique and innovative as they are generator systems that are capable of running off of propane or gasoline. When you are facing power outages or just need power off-site, you want to make sure that you have the very best machine for the job. There is simply no sense in investing in a machine that isn’t going to be able to power the items that you need to be powered. This is why you need to sit down and consider several different factors before you run out and just blindly by the first generator you come across. You can read any number of dual fuel generator reviews you want, but if you truly want to make the most informed decision, you need to understand what factors to consider.

The Power And Size

Power and size are two important factors to consider when you are shopping for the best propane generators. Most of the best models come in rather large sizes, but that doesn’t mean that you can’t get a portable generator that is capable of powering the items that you need to be powered. The main thing to consider is the items that you want to be powered. You need to make sure that the generator is capable of pumping out the watts that you need. If you are using the generator for off-site jobs, you will probably want to consider portability, as you will be taking the machine from job site to job site.

Fuel Storage And Temperature

When you are shopping for the best gasoline generators, you have to consider the fuel storage and temperatures. Gasoline is a popular choice when it comes to generators because they are overall more affordable, but the downside is that gas does not have as long of a shelf life as heat will make it evaporate. Propane, on the other hand, does not evaporate in extreme heat, but it will not react well to cooler temps. Anything below 40 degrees F will cause a pressure drop that might make starting hard. This is where dual-fuel generators excel because you literally get the best of both worlds, but you have to consider where you are storing your fuel. Make sure that you store it in appropriate locations.
