Electrical generators are not only for emergencies and power outages. Although their existence may be attributed primarily to this need, they have other purposes as well that are worth a second look especially if you are looking to purchase one in the future.

Like any other buying decision, the first thing you want to evaluate is the need. If you can answer the question on what you need a power generator for then you are already half-way there as there are generators that will suit majority of the needs out there.
If you are thinking small and only require a portable unit that can power a small motor home, then a 1 kilo watt (kW) model may be enough. If you need more juice to run heavier appliances, a 2 kW model may be just right. If you need one that can power an entire house or an entire business establishment, you may need to go for 5 to 7 kW machines that could supply a lot of electricity. (For more info, refer to the generator wattage guide)
Furthermore, you will also need to check what the outlets available in the generators that you can plug in your electric appliances. There are, of course, outlets for both 120 and 240 volt appliances but you will need to ascertain what your generator is coming with because this can be different from region to region.
And finally, you will need to decide on which fuel type you prefer in your generator. The most common are gasoline, propane and diesel.
If you wish to save on fuel costs, then you should go for a silent diesel generator as they are generally more efficient and economical and should outlast the other two because diesel is actually a light grade oil that helps protect the generator engine mechanisms from wear and tear. Gasoline and propane generators will probably require higher maintenance costs because of this.
To sum it up, deciding on your silent generator purchase requires just a few considerations; the most important of which are your power requirements, outlet requirements and longevity of the machine. I am hoping this article helps you in your decision.
