Does the thought of a power outage leave you feeling powerless? It’s time to take control with a home generator. This comprehensive guide will help you understand home generators, their benefits, and how they can be a life-saver during power outages or emergencies.
Let’s start with the basics.
What is a Home Generator?
A home generator is a device that provides electrical power to your home during a power outage. From powering essential appliances like refrigerators, heaters, and lights, a home generator ensures your home continues to function even when the main power grid fails.
How Does a Home Generator Work?
Home generators work by converting mechanical energy into electrical energy. When there’s a power outage, the automatic transfer switch of the generator detects it and turns on the generator. Once the main power grid is back up, the transfer switch also automatically shuts off the generator.
The Transfer Switch
So, what exactly is a standby generator transfer switch? In simple terms, it’s the brains of your generator system. During a power outage, it senses the loss of power and automatically switches your home from the grid to your generator. Once the power returns, it switches you back, ensuring a seamless transition and uninterrupted power supply.
How Does The Transfer Switch Work?
Think of it as a traffic cop directing electricity. When the power goes out, it stops the flow of electricity from the grid and reroutes it from your generator instead. This happens within seconds, so you barely notice the power cut.
Automatic or Manual Transfer Switches
There are two main types of transfer switches: automatic and manual. Automatic ones, like our traffic cop, do everything without any human intervention. On the other hand, manual switches require you to physically flip the switch when the power goes out and then flip it back once the power is restored.
Here’s a hypothetical situation. Take Jane, who lives in an area prone to storms. She used to worry about food spoiling in her refrigerator during power outages, or her basement flooding because the sump pump would stop working. Ever since she installed a standby generator with an automatic transfer switch, she no longer has these worries. Even if she’s not home, the transfer switch ensures her generator kicks in immediately when the power goes out.
When shopping for a transfer switch, popular brands like Briggs and Stratton are a good starting point. They offer a range of reliable, high-quality switches suitable for different power capacities. Key features to look for include the type (automatic vs. manual), compatibility with your generator and electrical system, load capacity, and ease of installation.
Fuel Sources
When it comes to powering your home standby generator, there are three main fuel source options: natural gas, propane, and diesel. Each has its own set of advantages and disadvantages, so let’s dive in and explore them.
Natural Gas
Natural gas is a popular choice because it’s readily available in many urban areas through local utility lines. It’s also relatively clean-burning and cost-effective. However, during severe storms or natural disasters, these lines may be compromised, disrupting your fuel supply.
Propane
Propane, on the other hand, is stored onsite in a tank, ensuring you have a fuel supply even if local utilities are down. It burns cleanly and has a long shelf life. The downside is that you’ll need a large storage tank, which requires space and regular maintenance. Also, propane prices can fluctuate significantly.
Diesel
Diesel generators are known for their efficiency and power. They’re often more durable and have a longer lifespan. However, diesel fuel doesn’t store as well as propane – it can degrade over time. Diesel engines can also be noisier and emit more pollutants.
Fuel Storage and Safety Considerations
⚠️ Safety should always take center stage, no matter what type of fuel you use.
Types of Home Generators
Home generators come in two main types: standby and portable generators.
Type 1: Standby Generators
Standby generators are permanently installed outside your home and can automatically provide power during an outage. They are connected to the home’s electrical system and a fuel source, such as natural gas, propane, or diesel.
This type of generator is used in residential, commercial, farms, schools and even public infrastructure.
The key is that standby generators provide an automatic, immediate source of power when the main power supply fails, making them suitable for any situation where uninterrupted power is critical.
Benefits Of A Standby Generator
While portable generators do have their benefits, such as mobility and lower initial cost, standby generators are generally more convenient and powerful, making them a preferred choice for many homeowners.
- Automatic Operation: Standby generators automatically kick in when there's a power outage, providing uninterrupted power. You don't have to manually start them, which can be particularly beneficial during inclement weather.
- Higher Power Capacity: Standby generators typically have a higher power output than portable ones, enabling them to power more appliances simultaneously. This means your home can continue to function almost normally even during a power outage.
- Direct Fuel Source: Being directly connected to a home's natural gas or propane supply eliminates the need for frequent refueling which is required with portable generators.
- Safety: Standby generators are installed professionally and are safer to operate as they turn on and off automatically. They also emit less carbon monoxide compared to portable generators.
- Quiet Operation: Standby generators are usually quieter than portable ones, causing less noise pollution.
- Value Addition: A standby generator can increase the value of your property because it's a permanent addition to the house.
Type 2: Portable Generators
Portable generators are mobile units that need to be manually started and can provide temporary power. They run on gasoline or propane and must be used outdoors due to exhaust emissions.
These are typically used for camping, RV living, remote emergencies and other outdoor activity uses.
Benefits Of A Portable Generator
While standby generators offer automatic operation and higher power, portable generators provide flexibility, mobility, and cost-effectiveness, which can make them a preferred choice for some users.
- Mobility: Portable generators can be moved around easily, making them ideal for use in multiple locations like camping trips, outdoor events or worksites, not just at home during power outages.
- Lower Initial Cost: Portable generators are generally less expensive to purchase than standby generators. This makes them a more accessible option for those with budget constraints.
- Manual Control: While requiring a bit more effort, the manual start-up of portable generators could be seen as a benefit by those who want more control over their power usage.
What is the difference between standby (whole home) and portable generators?
Standby generators, also known as whole-house generators, are permanent installations that automatically kick in during a power outage. They connect directly to your home’s electrical system, offering a seamless transition during power cuts. Although pricier than their portable counterparts, they provide a higher power capacity, enough to run multiple heavy-duty appliances simultaneously. This makes them ideal for extended power outages. However, they require professional installation, dedicated space, and adherence to local regulations, which could add to the total cost.
On the other hand, portable generators are compact, movable units designed for temporary use. They are manually operated, requiring you to start and stop them as needed. While they are much more affordable than standby generators, their power capacity is limited. Despite this, they offer versatility, perfect for camping trips, outdoor events, or as a backup for small businesses. Their main drawbacks include the need for frequent refueling and potential noise pollution.
When Would You Need a standby Generator?
Remember, unlike portable generators, standby generators start automatically when there’s a power outage and stop once the power is restored, providing a seamless transition and peace of mind.
- During Power outages Caused By: storms, natural disasters, or grid failures.
- Frequent Power Outages: If you live in an area that experiences frequent power outages due to severe weather, equipment failures in the power grid, or other reasons, a standby generator can provide uninterrupted power, keeping your home functioning normally.
- Medical Equipment: If you or a family member relies on electrically powered medical equipment at home, having a standby generator is crucial to ensure the equipment continues to operate during a power outage.
- Preserving Food: Standby generators can keep refrigerators and freezers running during a power outage, preventing food spoilage. This is especially useful in commercial cases where tons of product can be lost.
Generators can save the day by ensuring you have a consistent power supply in these situations.
