The increase in the demand of whole house generators are claimed to be increasing because people cannot afford, for hours and days, to be without it, and this is a good reason behind this demand. The need to have a backup power that kicks in immediately is recognized by homeowners who are especially located in areas where power outages are common, and thus they are covered with power for hours or days that are needed. The option to use a portable generator for homeowners to power their home is available, but if they need power for days, it will it inconvenient them since they have to go through the process of refueling and maintenance. To suit this purpose, only a whole house generator is a homeowner's option.
With an automatic transfer switch together with the whole house generator, the generator can function best because as soon as an electrical power failure is detected, the switch will turn on the unit immediately. The advantage of an automatic transfer switch is that when the voltage would suddenly drop because of fluctuation, the switch will disconnect the house from the grid, letting the whole house generator take over the function of providing the house with continuous power with the proper voltage. It is therefore a big benefit to have this system as there is an automatic on and off of the whole house generator as compared to the portable generator. Thus, you do not need to go outside during a very freezing weather just to set up the unit and crank start it up. Watch this video https://www.youtube.com/watch?v=Kjte_-DbeBU about generator.
Note that whole house PA Generators are sold in abundance in the market. The choice of which unit you will purchase will depend on the size of your house, the number of electrical appliances that you want to have power while there is an outage, and which brand or manufacturer you want to purchase. You have also the option to use a smaller and less expensive brand unit if it is fine with you not to use your air conditioning, hot tubs and other luxury items during the power outage. A unit that is known for reliability, fuel efficiency, quietness and has the ability to generate your required power capacity with ease is your best choice and guidance when purchasing your unit.
Other considerations in deciding to get a whole house generator are the frequency of the power outages, and if these outages happen during winter time, as you cannot imagine yourself setting up a portable generator in the middle of a winter storm for example, read more here!
When you look at the price of the unit, it is recommended that you look at the features of the unit, the capacity you need in your house and its fuel requirements, before purchasing it.
