  • Gas-powered – A gas-powered generator is an excellent choice for most homeowners. The fuel is easy to find at local gas stations and relatively inexpensive. However, you’ll need to ensure you have enough power to operate the generator for a sufficient amount of time.
  • Solar-powered – A solar-powered generator uses solar panels to generate power. A solar-powered generator can be a great option if you live in a sunny climate. However, these models can be more expensive than other models.

How to calculate the size of the generator you need

Before you start shopping for a generator, you should know how many watts of power your home needs. To calculate the size you need, consider the following:

  • Watts – The amount of energy your home uses (measured in watts) determines the size of the generator you need.
  • Amps – To determine the number of amps your home needs, add the total number of watts all your appliances use.
  • Volts – Your home’s voltage determines the generator you need. The correct generator size for your home will ensure that you have adequate power for all of your essential circuits.

If you purchase a too-small generator, it may not have enough power to provide adequate power to your home’s circuits. Likewise, if you buy a too large generator, it might not be able to manage the load properly and could trip the circuit breaker.

Where to buy a home generator

Before you make your purchase, you should decide where you want to buy your generator. There are two options you can choose from:

  • Retail stores – Home Depot and Lowe’s typically offer a variety of generators and are a great place to start your search. However, you may find yourself overwhelmed by the selection, and unsure which model suits your needs.
  • Online retailers – Online retailers like Amazon and eBay also have a wide selection of generators. As with the retailers listed above, you may be overwhelmed by the options and need guidance on which model is right for you.

When you purchase a generator, it’s essential to maintain it regularly to ensure it operates properly. When you don’t use your generator regularly, you should perform maintenance once a year.
