With generators, size matters. Proper Whole House Generator sizing is important to the success of any installation. It needs a good knowledge of electricity and the load requirements of the home appliances. When checking electrical loads, one needs to look at the manufacturer data plate on the equipment or machine to determine the starting amperage. This sizing guide will help one know what the ideal generator for home is.

 top rated whole house generators size options are rated by kilowatt, which is abbreviated as kW, and it measures the total load or capacity that the generator can handle. For home-owners who want an excellent whole house generator power solution, a 20kW is an ideal choice. Bigger homes will do well with a generator in a 26-36kW range. These generators are equipped with advanced load-managing hardware that will not overload the system. If one is looking for the ultimate backup system, then a 48kW generator is capable of producing the power needed to run your home like a blackout never occurred.

A permanent generator that provides 10-15 Kilowatts will typically cost between $3,000 – $10,000, and an added $400 – $1,000 for installation fees. A larger generator that can provide 20 – 40 Kilowatts will usually cost between $5,000 and $20,000. These generators will operate even if one is away, saving one the headache of returning home to a refrigerator full of spoiled food. In terms of relative costs, it’s often wiser to spend that extra $500 or so on higher wattage for one’s family needs.

To determine the best whole house generator for one’s needs, make a list of items one would want to be powered during a blackout. Each device should have a watt rating. If there is only an amps rating, multiply that number by 120 to find the wattage. If an appliance uses a motor, one will have to find the startup wattage and use that instead. Add up the total wattage of the items, and then add an additional 10 or 15 percent to be safe. This is the amount of power your choice of the best whole-house generator must provide in order to meet your needs.

Even the best whole house generators involve extra costs such as fuel tank installation and set up fees, consider that generators are generally a little larger than comparable AC units, and regulations usually require that they be located x amount of feet from property lines or dwellings, and concealed by fences or shrubbery, all of which can add up. Some local regulations may also include periodic inspections.

When it comes to generators, power is calculated in watts. The higher power outage, costlier the generator would cost. One needs 600W to light up a refrigerator, 60 to 600W for lights (depending on how many you have in the house), 1,000W for a window air conditioner, 60 to 300W for a computer or laptop.

Often people complain about generators being super loud, which is also one of the reasons why they don’t purchase one. Some generators make so much noise that it won’t let you sleep in the night. It can be horrifying if one has small children at home, one can sleep better when it is completely silent.

When it comes to the safety of delicate electronics, all the generators that are included in the below list are good. They all have a total harmonic distortion of less than 5%, which means it protects the most sophisticated electric equipment.

Size is one of the features you should check before purchase the smallest generator that fulfills all the needs. It will maximize fuel usage. It also depends on the frequency of power outages for which one will require a standby generator with a power output of around 20 to 22 KW.

Taking into account how pricey these units are, be sure to go for at least 5-year warranty for whole house generators.

Greatest benefit of having a whole house generator at hand is the peace of mind, when one knows that the life won’t be disturbed by electricity outages, be it for hours or days.

Since the generator is connected to house’s electrical panel, one does not need to go out and turn the switch on, connect extension cords, and connect it the home appliances. Just sit back and relax because everything is happening on its own.

One can expect the whole house generator to start working within five minutes of power outage. Some good quality generators start working in less than 10 seconds so that one can continue their work without any disturbance. One also does not have to worry about food in the refrigerator getting spoilt nor about the temperature of the house getting very cold.

First of all, one does not have to worry about extreme heat or cold affecting the family and because the generator will maintain room temperature. Instead of going to hotel to stay in because of the storm or hurricane, one can stay in the comfort of home and save hundreds of dollars. The food is maintained at high quality; one can shower, one can work from home, and also keep the kids entertained inside house because one can run the television and Wi-Fi using generator energy.

Owning a house without home insurance is a risky business even though it is a costly expense. When one installs a whole house generator for the house, most insurance companies give a discount because the risks attached to the home are less compared to their average model.

There’s nothing more comfortable than being in the home during a natural or man-made disaster. When one has a generator to power the whole house, one does not have to worry about how one will go through it. One can continue living one’s life seamlessly and even help people out of danger.
