Understanding Your Options for Backup Power at Home
When the power goes out, how prepared is your home? For some homeowners, a power outage is little more than an inconvenience. For others, losing electricity can mean no heat, no running water, spoiled food, or the inability to operate essential equipment.
Fortunately, there are several ways to provide backup power to your home. The two most common options are automatic home standby generators and portable generator systems. Both can be excellent solutions, but they differ significantly in convenience, capability, and cost. Understanding those differences can help you decide which system makes the most sense for your home and your budget.
Automatic Home Standby Generators
What Are They?
An automatic home standby generator is designed to provide backup power with little or no involvement from the homeowner. These generators are permanently installed outside your home and connected to your electrical system through an automatic transfer switch.
How Do They Work?
When utility power is lost, the generator automatically starts, and the automatic transfer switch restores power to your home. When utility power returns, the system automatically transfers your home’s electrical load back to utility service. The generator then goes through a brief cool-down cycle before shutting itself off, ready for the next outage.
Who Benefits Most From a Home Standby Generator?
Automatic standby generators are particularly valuable for:
- Rural homes that experience frequent or extended power outages.
- Homes that rely on private wells for their water supply.
- Homeowners who need dependable heating or cooling during an outage.
- Households with medical or other essential electrical equipment.
- Anyone seeking the convenience and peace of mind of automatic backup power.
For some homeowners, an automatic standby generator is a convenience. For others, it can be an important investment in their home’s safety and comfort.
What Does a Home Standby Generator Cost?
A professionally installed home standby generator system can typically range from $12,000 to $25,000, depending on various factors, including the size of the generator and installation requirements. While this is a significant investment, the convenience and capability to power much or all of your home can make it worthwhile, particularly in areas prone to outages.
Portable Generator Systems
What Are They?
Portable generators offer a more economical approach to backup power. Unlike automatic standby generators, portable generators must be manually started and connected to the home’s electrical system through an approved transfer system.
Types of Portable Generator Systems
Small Portable Generator Systems
For homeowners who only need to keep a few essential items running, a small portable generator may be sufficient. A basic system can use an individual transfer switch to supply power to specific circuits, such as:
- A gas furnace for heating.
- A refrigerator or freezer to protect food.
- Other essential household circuits.
With this setup, a small portable generator can be connected using a properly rated cord and approved connection. This can be a practical and affordable way to keep essential equipment operating during an outage.
Larger Portable Generator Systems
For homeowners wanting to power more than one or two circuits, a larger portable generator is a better choice. Generators equipped with a 240-volt, 30-amp or 50-amp output can be connected to appropriately rated manual transfer switch systems, allowing homeowners to select and operate approximately 10 household circuits.
Examples of circuits that might be included are:
- Refrigerators/Freezers
- Gas furnace
- Kitchen outlets
- Lighting
- Garage door opener
It’s important to note that while you may have 10 circuits connected, you cannot operate all at full load simultaneously. The generator’s wattage limits how much equipment can operate at one time.
What Does a Portable Generator System Cost?
One of the biggest advantages of portable generator systems is affordability. Installation costs for a basic single-circuit transfer switch typically range from $400 to $600, making it an excellent option for maintaining essential systems during an outage.
For those wanting to power multiple circuits, a 10-circuit manual transfer switch installation generally ranges from $2,000 to $3,000. These prices do not include the portable generator itself, which is purchased separately.
Choosing a Portable Generator
Portable generators are available in various sizes and prices. Smaller generators capable of supporting one or two essential circuits can cost as little as $500, while larger, dependable portable generators equipped with a 240-volt, 50-amp output can cost as much as $3,000.
At High Current Electric, we can help customers select a generator that meets their needs based on experience and customer feedback.
We’ll Show You How to Use Your Generator System
Having a backup generator system is only helpful if you know how to operate it when the power goes out. At High Current Electric, our service doesn’t end with transfer switch installation. We provide guidance on:
- Connecting your generator
- Starting it
- Operating your manual transfer switch
- Safely restoring power when service is back
In addition, we discuss best practices for using your generator, understanding its limitations, and preparing for the next outage.
Which Generator System Is Right for Your Home?
The right choice will depend on your power needs, the frequency of outages, your desired convenience level, and your budget. An automatic standby generator offers the greatest convenience and can supply whole-home backup power when properly sized.
On the other hand, a portable generator system requires more homeowner involvement but can provide reliable power for essential circuits at a lower cost. At High Current Electric, we believe the best generator system isn’t necessarily the largest or most expensive; it’s the one that meets your needs, fits your budget, and provides peace of mind.
