The majority of portable generators for households vary in power from 4,000 to 12,000 watts. Their size and cost are determined by the number of electrical devices that will be used at the same time. Power requirements for common household items These gadgets require a total of 4,700 watts to operate, yet a 4,700-watt generator is insufficient. Most people with this type of application need a 5,400- to 6,900-watt generator.
Things can get pretty crazy at holiday parties. The researchers estimated that a typical home entertainment system requires about 600 watts while playing back DVD discs. That's not very much power compared with other appliances running at the same time! To meet the demand at the party, you would need a fairly large generator, one that produces about 5,400 watts or more. One way to save some money would be to share the load between two smaller generators. For example, if you have a 5,400-watt generator and a 2,700-watt generator, then five people using 1,350 watts each would not use up both generators at the same time.
Power outages can be dangerous because they cause lights to go out, heaters to shut off, and other appliances to stop working. A generator is always ready to go when electricity is needed most. It keeps food from going bad, maintains a comfortable temperature inside your home, and protects against identity theft during these times when the main power source is down.
A generator rated at 5,000 to 7,500 watts can power the most vital household appliances. A well pump, refrigerator and freezer, and lighting circuits are examples of these. All of these appliances may be powered at the same time by a generator with roughly 7,500 operating watts. A 3000–4000-watt generator would be perfect for an RV. These come in several sizes and costs from $750 to $5000.
Appliances that use heat like dishwashers, dryers, and ranges need more than 7,500 watts. They usually run between 10,000 and 20,000 watts. Your best option here is to purchase an appliance controller such as an Energy Star device or a traditional electromechanical unit. These controllers can reduce the energy used by these appliances by up to 90 percent while still allowing them to operate when electricity is available.
Traditional generators are only efficient enough for small appliances. If you want to power a washer/dryer pair or even a hot tub, you'll need something bigger. Generators designed for home use are limited to about 2,000 watts because they use electric motors instead of internal combustion engines which are much more efficient at low speeds. A generator this size should be able to power a refrigerator, freezer, air conditioner, heat lamp, and toilet (depending on how many hours of operation you need it to last). One called "Big Bertha" has been recorded as powerful as 10,000 watts but this is unusual.
Up to four lights, a fan, an electric motor, and a refrigerator may be powered by a 5 kW generator. Small residences may run on such a simple generator. However, the optimum generator for a residence should have a capacity of at least 10 kW. This will allow you to keep up with all of your household's needs during a power outage.
The amount of power that a generator produces depends on how quickly it uses up its stored energy source: gasoline or diesel fuel. A generator's horsepower rating is used to determine how fast it will use up its fuel supply. If your generator has a 1,500-watt engine, it can drive a heavy load for about 15 minutes without additional fuel. A 2,000-watt engine could drive a heavier load for about 30 minutes. A 5,000-watt engine could power a heavy load for about an hour. The more horsepower your generator has, the more power it can generate.
A generator's maximum output determines how many lights you can use, how much heat it can release, and how large a refrigerator you can power with it. Generators come in different sizes, ranging from small generators for use inside homes that are only capable of powering several lamps to large generators used in factories that can power hundreds of lamps.
Most households need a generator that generates between 500 watts and 3 kilowatts.
How much electricity can a generator generate? In general, generators for household usage may provide 3000–6500 watts of electricity to fulfill minor basic demands, while a 5000–6500 watt generator can operate a bigger furnace or well pump. It's critical to assess your power requirements before purchasing a generator. You'll need enough electrical capacity to run all the appliances you expect to have on at once. If you plan to have several large appliances such as heaters, air conditioners, and dishwashers running at once, then you will need a generator capable of producing at least 7000 watts.
In addition, many generators require some degree of maintenance, which includes checking the oil level in the engine every few months. A full service replacement of the engine is necessary if it runs out of oil. Other common-sense maintenance tasks include cleaning out any fuel filters regularly and replacing worn out parts like belt and pulley systems.
Electricity from generators cannot be stored and used later when energy needs increase. It can only meet current demand. The amount of electricity available at any given time depends on many factors, such as wind speed and rainfall. As long as the generating source remains adequate to supply more than your immediate needs, there will be no problem. But if the source becomes exhausted, you will have to reduce your own use of electricity or wait for another day with similar conditions.
Many of the equipment need to keep your basic household appliances operating may be powered by a 12,000 watt generator. While it is not ideal for bigger homes or full-home electricity, it can readily power fans, lights, TVs, refrigerators, and other appliances. These generators are also able to run vehicles using her engine as a starter motor which provides motive power during start up.
The size of your generator will determine how much power it can supply. A small generator designed for specific appliance use can provide up to 1000 watts, while a large generator used for backup power needs can supply up to 10,000 watts. Most residential units range from 1500 to 5000 watts. It's important to choose a size generator that can handle the load you plan to put on it. Overloading a generator will cause it to fail sooner.
Generators come in two main types: single phase and three phase. The type of wiring needed for your home is usually indicated by what kind of plug goes into the wall outlet. If you have single-phase power available at the wall, then any generator should be single phase. Three-phase power is more difficult to generate with most generators because they only produce power on one side of the circuit, so both wires of a three-wire cable must be brought out of the house for connection to a generator. Special three-phase generators called splitters are available but they are very expensive.
