Power outages can occur at any time. When they do, it is important to have a backup plan. The last thing you want is to stay in the cold because the HVAC system is not working. For businesses, power outages lasting for a couple of hours can translate to huge losses. This is why you should have a backup plan to mitigate such losses or inconveniences.

There are different types of generators in the market. The generators can be classified into two: standby generators and portable generators.

Standby generators are large generators that are powered by natural gas or propane. These generators automatically switch on to supply power in case of an outage.  You should expect to spend upwards of $5,000 for a standby generator producing 7,000 watts of power.

For homeowners, portable generators are ideal for purchasing. These generators are typically smaller and produce a lower wattage. The generators are powered by gasoline and cost from $500 to $1500. You can use the generators to power the essential appliances in the home such as refrigerator and microwave.

One of the things you have to decide before starting to shop for a generator is the size to go for. Here, you should consider your needs.  Make a list of all the items you would like to power in your home or business. After this, check the labels on the items for information of the amount of watts is needed to power them. The labels may also contain other information such as the year the appliance was made and its model number.  Depending on the appliance you have, the label may be at the back, inside the door or outside. To learn more about portable generator, follow the link.

Note the wattage requirements of all the items you will need to power. These may include freezers, refrigerators, a sump pump or other pumps you may have. The air conditioners and over use a lot of power and hence should not be on your list of essential items that have to be powered by a generator. For an oven, you can use a microwave as an alternative. For an air conditioner, you can go a few days without using it. If you would like to power such items, you may need a generator with a higher wattage capacity.

Add all the wattage requirements of the items you will be powering and then multiple the total by 1.5. This is because appliances typically require extra power to start up. From there, choose a refrigerator that can supply higher wattage than the total you will have gotten.
