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. The whole house generator would best suit for this purpose then.
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. Further, the automatic transfer switch will disconnect the house from the grid even if the voltage will suddenly drop due to a fluctuation, and letting the whole house generator take over the job of giving a continuous power to the home at the right voltage. What separates this system from the portable generator is that this whole house unit would automatically turn on and off which proves to be a big advantage. Imagine not needing to go outside just to set up the unit and crank start it on a very cold weather.
Be aware that there are a lot of whole house generators that are available 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. If you are able to avoid not using air conditioning, hot tubs and other luxury appliances during the outage, you can choose to purchase a smaller and less expensive unit. It is advisable that you look for a unit that is known for its reliability, fuel efficiency, quietness and that can generate with ease the required capacity of your home.
The factors of considering the frequency of the power outages, and if these outages usually happen during winter when it would be a terrible experience to set up and start your portable generator in the middle of a snow storm, would be your guidelines in deciding to get a whole house generator.
It is advisable to check out first the capacity your house needs, fuel requirements and the features of the unit, before you make the final decision on which unit you will buy.
