Types of Generators

Portable Generators

Portable Generators are usually small, compact generators which you can take with you during travel. The usual wattage for these types of generators are 5000 watts which can power different small to medium sized appliances for about 8 hours. The most common way of using portable generators are through extension cords through a window. You can only plug 1 or 2 items in a small portable generator. Portable generators are used during power outages and also during camping out.

Home Generators

Home Generators are usually standby generators found at the basement. They function as emergency standby generators when there is power outage. Home generators should have the capacity to supply electricity to the majority of the house, not just a few circuits. Bigger home generators can be installed outside the house where there is automatic transfer switch if the main electricity goes out. It can run on natural gas, propane or diesel. State of the art home generators will automatically kick in when the power goes out. There will probably be a 15-20 second delay for the generator to respond.

Diesel Generators

Diesel Engine Generators are designed for a small to medium sized business establishments. It is designed for heavy usage. There are two types: two stroke and four stroke diesel generators. Most diesel generators patronized by business owners are 4-stroke generators. It also comes in either single or three phase power. The modern diesel generators are now generally quieter than the older versions.

These three types of generators are the most commonly purchased, used and highly rated by both the ordinary homeowner and the small-medium sized owner. Portable generators are for those that plan to move frequently (i.e. dispersed campers) or for those that want a backup power for limited home appliances. The home generator is intended to power partial or an entire home during power outages. It is suitable for homes since it can automatically provide electricity to your home the moment to power goes out. If you have a big house or a business that needs uninterrupted power supply, the diesel engine is best for you.

Which among them is the best for you to purchase? Here are more factors to consider before investing in a generator system:

Generator Purchasing Factors

  • Power Output = rated watts can be as low as 5kW which can provide power to multiple “survival appliances” to 30 kW which can power a mid-sized to large home or business. What will you use the power for? Decide according to what your needs are. The common emergency backup power should be able to provide 10kW.
  • Run Time = How long do you need the generator running? Is 8 hours enough or do you need the generator running at least 24 hours. Generator fuel consumption matters.
  • Price = Price is a very big factor in deciding which generator to purchase. Most homeowners who need a backup power purchase portable generators instead of a home generator because of the budget. Although this is a common practice, portable generator sets will only be able to provide a few basic appliances electricity. Investing in a generator system can go for as low as $500 and as high as $2500. Of course you can buy a cheap generator on sale, but is it worth it? Usually not, as these are Chinese made generators which haven’t been built as robust as say a Yamaha, Honda or Westinghouse.
  • Noise = you wouldn’t want a noisy generator set around the house when there is power outage. Diesel generators tend to be noisier than other types of generator but are more reliable when in terms of giving uninterrupted power. You should consider where you will place your generator system which will not make your neighbors hate you for noise pollution.
  • Portability = Will you use your generator outdoors or will you just need it as a standby power supply at home? If you want something that is portable, you should be contented with the basic generator that can supply electricity for “survival” appliances.
  • Reliability = Of course in investing a couple of hundreds of dollars, you have to be sure that the product you are buying is of quality. Some generators which may be cheaper because they are made in China can perform well in about 3 months to a year but can you rely on these cheaply manufactured generator systems for 5 years or more. You do not want your house burning up because of a generator set which is substandard. When it comes to which factor is most important to consider, it is the reliability of your gen set and not the price, not just because you want a quality product but because you want your home and business to be safe from hazards. So, do not purchase substandard generators which are unreliable in the long run.

Choosing the best generator set for your home or business totally depends on your preference, budget and need. Do not shorthand yourself when purchasing something which you think is essential for your home or business. Let Generator Power Source help you make the more intelligent investment!

Top Five Generators for the Money

When investing on an equipment that you are not familiar with, you have to ask around about what the product has in its features, which is the product best suited for, and of course the price.
