Which Home Generator Do I Need?

Whether you’re looking to use a generator at your home, workplace, or for a recreational vehicle, there are a few factors to consider:

What are the Different Types of Home Generators?

There are plenty of home generator options to choose from, including whole-home standby generators; large, medium, and small inverters; portable generators, and more. Many standby home generators are powered by natural gas, and switch on automatically in a power outage without requiring refueling. Inverters cover a wide range of uses and can power anything from a few appliances to a whole small house. Portable generators usually offer the best value for your dollar, but are often limited in their output. Call the home generator experts at Mainstream for a comprehensive proposal to get help determining which home generator works best for you!

What Size Generator Should I Buy for My Home?

The size of the home generator that you choose to buy depends mostly on what you’ll be using it for. If you need a home generator with capacity to power your entire home for prolonged periods during an emergency, then you’ll probably need what’s called a standby generator. These are permanently installed outside your home, and are generally the most expensive option. Large and medium inverters are another good option if you’re only looking to power a few key appliances during a power outage.

How Much Power Does My House Need?

Your home generator should be able to power the combined wattage of all of the appliances you want running when the power goes out. Calculating exactly what wattage you need can be tricky, and is potentially dangerous if calculated incorrectly. The generator installation experts at Mainstream can help you decide exactly how much power your home needs with a personalized, home generator installation proposal.
