Generators are good investments in places where there is constant power outage or a low supply of electricity. A generator is a good back up for electricity when there is a shortage of power for whatever reason. The generator can be used to power your whole house or you can use it to power a few appliances which you feel need the power more. Appliances like the refrigerator, water pump, heating systems and other core appliances that are needed in the home. There are various types of generators of varying sizes and mobility. The main fuels used for powering a generator are gasoline which is the cheaper and more common option, propane and natural gas. The type of generator you get can be influenced by the type of fuel that is readily available for you to use to power it, and whether or not you can afford it.
Generators from generac dealers can also be portable or immobile. The portable brand of generators is usually small in size, cheaper and easier to install. The portable generator can only be used to power a section of the house or a few appliances. The portable generator has to be started manually, and is quite noisy which could be a problem.
You will also have to decide how much fuel you're going to need to power your appliances for the needed amount of time before the power returns. Immobile or standby generators are powered by either propane or natural gas. They are installed into the home's circuit panel which enables them to start up automatically when the power goes out. The standby generator is capable of powering the whole house and probably all the appliances in it. It is the more expensive option compared to the portable generac power systems maintenance.
Regardless of the size of generator you decide to get, you should always get it installed and regularly maintained by a licensed electrician. A licensed electrician will have the knowledge and experience on how best to connect it to your home's circuit and determine which size of generator is the best option for your needs. A generator installation will require a permit from the municipal authorities, and you will have to ensure that it is not a violation to the regulations in your municipality due to the noise it will cause. It is very vital that you never use a generator indoors or in a closed area, so as to prevent carbon monoxide (CO) poisoning which is very deadly. Keep generator units away from open windows and doors to prevent inhalation of the deadly smoke.
