Zellner Electric is an authorized Generac dealer for residential generators sales & installation. A home backup generator also called home standby generators automatically delivers power directly to your home’s electrical system, backing up your entire home or just the most essential items.  As a homeowner, buying a backup generator could spare you financial losses, like food spoilage, when power outages strike. Power outages can leave you and your family without everyday conveniences like refrigerators, ovens, washing machines, and heating and cooling systems.

The generator will run until utility power returns – whether that’s two hours or two weeks.

A main reason it is worth it to buy a home generator is to keep your refrigerator and freezer running smoothly to avoid food spoilage. Additionally, it is useful to power your office if you work from home and also to prevent the outage of any necessary medical devices.

Depending on the size of the generator you can run most critical household equipment like a well pump, refrigerator and freezer, and lighting circuits. A standby generator is an investment that pays for itself every time the power goes out while simultaneously increasing the resale value of your home.

Home generators can be sized to power your whole house or configured to power only what you need, when you need it. The size of the generator will be based on the amount of total watts needed.

For safety reasons and to ensure adherence to all local, state and national electrical codes, it is HIGHLY recommends you use only an experienced, licensed electrician. A transfer switch will need to be installed with manual or automatic functionality install at the house main service panel.

The American Red Cross recommends permanently installed backup generators as a safer way to provide backup power to a home than a portable generator.

A portable generator might be less expensive but can only handle the electrical demands of just a handful of appliances. A backup/standby generator is large enough to power all the appliances your family could need or have become accustom to using. Backup generators provide protection 24/7, whether you’re home or away, and they turn themselves off when utility power returns, so there is no need to monitor the unit during an outage. So while the rest of the block is in darkness, your house would continue operate and keep you and your family comfortable.

As long as there is a fuel supply of natural gas or propane, a well-maintained backup generator will keep running. If the Generac generator is running on propane, with a 500-gallon tank, it should run 24 hours a day for over a week.

Whole house backup generators work off fuels such as natural gas or liquefied petroleum gas (LPG) and sits outside just like a central air conditioning unit.
