Factors To Consider When Purchasing A Backup Generator For Home
A backup generator for home is an electronic device that automatically runs in the event of a power outage. An automatic transfer switch senses the electricity loss, orders the standby generator to begin operation, and then transfers the electrical load to the standby generator. The standby generator starts supplying power to all the various circuit breaks. The device has enough capacity to handle an electric failure but not enough capacity to provide for a complete power failure.
There are two types of standby generators, gas and electric. Gas standby generators work on natural gas and propane fuels. The gas generator will generally have an inbuilt engine with a capacity sufficient to run small appliances. There will be a storage tank to store the fuel as well as a pressure regulator so that the pressure is at a suitable level when the gas engine starts. Most standby generators for residential use are fitted with an automatic shut down system for total energy failure protection.
Other important factors to consider before buying a home backup generator are the maximum wattage and the minimum wattage rating. The maximum wattage is the maximum rated wattage that the device can use at any one time. The minimum wattage rating is the lowest wattage allowed to be used by the unit. These two values should match exactly for the device being purchased. The minimum wattage will be lower than the maximum wattage, allowing it to be used when the electricity goes out.
Another factor is the transfer switch and the air conditioning mode. There are standby generators that only support one type of transfer switch. This means that if you are using an air conditioning system, you will either need a transfer switch that is capable of switching between AC and DC, or you will need a transfer switch that supports both AC and DC. Some units have both a standby generator and an air conditioning system built into one unit. These are referred to as multi-tiered units.
The final aspect to consider is the size and the capacity of the fuel that the unit requires. The more fuel that is required, the larger the unit will need to be. The final number of watts that is supported should be adequate to power the basic home appliances that a person uses. If more weight is needed to lift a heavy object, then additional fuel capacity will be necessary.
Many portable generators can run on diesel fuel or gasoline. These fuels can be purchased in bulk at hardware stores and larger chain stores. Diesel fuel is usually more affordable and widely available. In addition, if there is enough demand for gasoline-powered standby generators, they will likely be sold at a discount.
A larger generator will have more power and a higher BTUs. However, it will also require a larger space to store it. Fuel sources should also be available in strategic places around the home to ensure the power does not go out unexpectedly. Gasoline and natural gas are generally cheaper options when compared to electricity.
