Portable and permanent are the two basic types of generators. The names say it all. Portable generators can be carried with you, and permanent generators are just that – permanent.
Since portable generators can only generate a small amount of electricity, they will only allow certain small appliances to run. Obviously, you will not be able to use a portable generator to apply power to your entire house in the case of a power outage.
Portable generators usually operate on gas or propane. Fuel tanks are built into the generator. Some portable generators can be plugged into an outlet. These are great for activities that require electricity without having to run three or four extension cords.
There are a couple of disadvantages to using a portable generator. One is that you have to manually start it. The other disadvantage is that you have to be sure to have the fuel on-hand for immediate use of the generator, if the power goes out. Once the main power has returned, you must also manually turn off the portable generator.
Portable generators can range from delivering less than 1 kW to delivering 15 kW. Of course, larger generators are available that can be towed to wherever you need the generator that produce 200kW or more. There are some portable generators that will produce up to 6,000kW!
Permanent (or standby) generators can power your entire house or business in case of a power outage. This type of generator is direct-wired to the building’s electrical system, and it is fueled by the city (or other entity) using gas or propane lines.
The advantage of having a permanent generator is that you don’t have to manually start it, and it can produce up to 20,000 kW of electricity. It automatically comes on when the power goes out and goes off when the power is restored. The disadvantage is that you cannot remove the generator, once it’s installed without a large sum of money, time, and manpower.
Regardless of which type of generator you use, be sure to install it with a transfer switch. This will turn off the home or office’s electrical current connection from the utility company before the generator starts running. By doing so, the generator’s electrical current does not back feed into the utility lines, thereby creating a safer environment for the utility workers.
Different generators with different wattages are offered at different prices. This is to be expected. Before purchasing a generator, whether portable or permanent, be sure to examine your specific needs. You need to purchase a generator that will help you when it’s supposed to.
Check the manufacturer’s warranty and installation/use instructions. Be sure to use your generator safely at all times. Again, be sure to purchase a generator that will sustain you and your family in a time of crisis.
