Home generators fall into two categories, the stationery built in type, which is more than likely a whole home generator and the portable type which can be set, to power selective appliances and lights as a matter of priority. It goes without saying that the higher the wattage on the generator, the higher the cost and the more complicated the installation. Basically it is a personal choice which will depend on finances, if you want to have your whole house powered during a power outage you would have to pay the price. Most people cannot afford this option as apart from the initial cost you would have to consider installation costs and also how much fuel you would need to power the generator on a daily basis.

A home generator is also an investment as it will add value to your home and probably reduce insurance costs. Bear in mind that there is also red tape that you might have to deal with, especially with the stationery home generators. Building permits and code requirements vary according to where you live, and it is a good idea to thoroughly investigate these issues before you purchase a home generator. Also find out what the noise level of the generator you want to buy is, this might also cause an issue with your neighbors. If you are determined to purchase a stationery unit to keep your whole house lit in an emergency, then it is a good idea to call in a trained electrician to assess your needs and give you an estimate. Installation costs can run into the thousands, depending on which unit you choose.

With a standby units, you would need at least 5,000W to power the basics of the average home. These units cost a lot less and they run on gas or propane. You can use them anywhere, even take them on camping trips. If you are using propane then these units must be kept away from the house and not in an enclosed area. With portable or standby generators you will have to calculate how much wattage you would need to power essential appliances like the refrigerator, and the lights. You can find models that are electric starting or with a battery that needs to be charged. Portable generators usually offer from 3,000 to 8,500 watts. There is also solar generators that can provide up to 2,000 watts of power. These are suitable for people living in rented homes or for those in small apartments. The battery charges with daylight panels which draw energy from direct sunlight.

How to Choose the Best Home Generator

What type of Generator do you want?

There are basically four types of generators, stationary or standby, portable and solar.

Stationary Generators

Also referred to as standby generators, these units are placed where the homes electrical grid is as it is linked directly to the electricity box. They automatically monitor the houses electricity and when there is an outage the standby generators will kick in and take over to supply electricity to selective lights and appliances, or the whole house. The unit will switch off automatically as soon as the electricity is restored. The stationery generators are installed permanently and are hooked up to an existing fuel source that is either propane, gas or diesel. The range of these generators is from 5,000 to 20.000.

Portable Generators

These generators usually come with a power range from 600 to 9,000 watts and run with gas, propane or natural gas. Once powered you will need to connect extension cords to your appliances from the receptacles on the generator. You can use them anywhere on or off your property and depending on the fuel source you would need to take the necessary precautions.

Solar generators

If you are living in a small apartment or flat, or are renting a home you will not want to go to the big expense of installing a generator. Solar generators are available for small premises and they can supply up to 2,000 watts of power. The solar generators get their energy direct from the sun through daylight panels.

Fuel Source

The options you have to power home generators are basically, gasoline, diesel, propane or the use of a natural gas line in your home.

Standard gasoline can be purchased easily and remain the most popular fuel used to power generators. Most portable models only run on gas.

Diesel is another option which you can purchase easily and also needs to be stored in tanks.

Propane is a popular source of fuel and it is easy to purchase tanks from any hardware or supermarket. Special safety measures are necessary with propane.

Natural gas-powered are usually used to fuel stationery or standby generators. This type of fuel runs naturally into your home as a fuel source.

How Generators Work

Automatic Start

Stationery generators are programed to start automatically when the power goes off. The installation of these generators would require a qualified electrician as a direct connection will have to be made to your electricity system.

Manual Start

With manual versions you would need to add a transfer switch as it would require you to fire up the generator and switch over to using it, to power your home.

Electric Start

Some portable home generators have a push button alternative which involves a charged battery that would fire up the generator.

Extra Accessories and Functions


Moving a portable generator without wheels is very difficult as they can weigh over 200 pounds. Wheels are essential. and in some cases you would have to order them separately.

Fuel Gauge

Being able to check the fuel levels so you can program refilling is essential with portable generators.

Low-Oil Shutoff

A generator should be able to shut off automatically when oil falls to minimum levels. This will prevent damage to the generators.

Inverter Technology

Most stationery generators and some high end portables, have inverter technology which provides cleaner power that won’t overheat.

Multiple Outlets

Stationery and portable generators that power up selected appliances and light will need multiple outlets to spread the load of power.

Transfer Switch

A transfer switch is essential in order to protect your appliances or damage to the generator. The transfer switch is linked to the circuit panel with one cable

Noise Factor

Some generators can be very noisy and running one continuously could cause problems with your neighbors. Consider the noise factor when purchasing a home generator. Whole house units and most stationery units that are placed indoors are insulated enough and will generally be quieter. Noise levels are measured in decibels and most manufacturers state this on their units. Basically the generator should be at least 25 feet away from your living area.

Installation Costs

All generators will require some installation, but it is the stationery whole house units that require the most complex installation. Starting with the cheaper installation, you might need to pay for are a fuel tank, installation and set-up fees. These would probably apply to all generators. Also consider that if you will be connecting the generator to the electrical supply of your home then you definitely need a qualified electrician to do the electrical work.

Connecting to your fuel source is another consideration and here you need to take safety into account. If you need to put the unit on a concrete slab, you will need to get another technician in to build it for you. Your local code authority will also need to inspect the premises to make sure that you are not contravening any regulations. It will cost you less in the long run if you hire a specialist in this field who knows what is required in advance and can ensure that all work will pass any inspection.

Safety Features

Standard safety issues should be strictly adhered to when you are working with gas and propane. Another consideration is a circuit interrupter which will prevent anyone from being electrocuted, if the current should take an alternative path. For electronic equipment like computers and phones, make sure the generator supplies a balanced electricity supply during outages as some generators could damage these sensitive items.
