Generator size based on your needs
There are a number of important things to consider when buying a new or used generator so you get a cost effective solution for your needs. The most important thing to look at is the size of the generator based on your needs. After you have assessed your requirements, the size of the generator can be determined, the fuel source, warranty and the all important maintenance requirements and costs.
So, start your search for a new or used generator by assessing exactly what you want the generator to power. Do you want a standby generator that will automatically kick in when the power goes off, and switch off by itself when the power comes back on? If so you will be looking at a permanent generator. If you want a backup power supply for only a few electrical appliances, then a smaller, portable generator may be what you require.
The first step to determine the size of the generator you require is to calculate the wattage of all the items that will be powered at the same time. Then increase that total by 20 percent to cover the initial power surge. Calculating wattage requirements will require you either check the manual that came with the appliance, any indication on the appliance itself, or check the net. If you have any difficulty, you could get an electrician to test the item and give you an accurate wattage figure.
Generator fuel type
Based on the results, you now have a good idea of the size of the generator you need. The hardest work is over. Now determine what sort of fuel source you want. If you are looking for a large permanent generator, they normally use either propane gas or natural gas, as that fuel source can be stored for longer periods than petrol or diesel. You can leave it ready to be used when ever the power goes off, whereas petrol does go off after a while. Portable generators usually use petrol or diesel as that is a cheaper fuel source and in most cases, easier to use.
Generator Maintenance
Next consider maintenance costs. Check out any user reviews regarding reliability and problems they have had. Also, if you can talk to mechanics that service generators, get their opinion. This should give you a fair idea of generators to avoid. Remember that if the motor is from a reputable brand such as Yamaha or Honda, you have a good guarantee of reliability.
Generator Warranty
Finally check out any warranty that comes with the generator and compare. These are some of the important things to look for when you are buying a new or used generator.
