Buyer’s Guide

What is a Standby Generator?

A standby generator is a generator that basically stands by you whenever you need a back-up power and operates automatically. They are permanently connected to your house with the help of a transfer system, hooked up to a fuel source. Just within seconds of a power outage, an automatic transfer switch senses that there is a power loss and begins to supply power to the circuits.

These generators unlike the portable ones which can be moved around are fixed in a specific static position and are much bulkier. They act as a back-up power source in case of emergencies and are generally used in hospitals, government buildings, industries, job sites, homes, etc.

Types of Standby Generators

  • Diesel Standby Generators
  • Gas Standby Generators
  • Bi-fuel Standby Generators

Diesel Standby Generators

Diesel standby generators are generally used in industries. They can operate completely independent of the grid and with their own fuel storage. But, they require refills more often than a gas-powered generator.

Diesel generators are firm and stable, with a long life span and less maintenance is required. Mostly, fuel maintenance is needed to be taken care of.

One of the disadvantages of a diesel engine is that the volume of its motor is louder than a gas-fueled generator.

Gas Standby Generators

Gas generators can usually run on either propane or natural gas. But in both cases, a gas generator needs an ongoing fuel source and is therefore connected to a gas line for continuous power.

Natural gas is considered to be more dangerous to store than diesel fuel. You must note that this factor can also make gaseous generators less stable than diesel in case of a disaster, as they are more likely to create fire hazards.

Things to Consider before buying Standby Generator

Power Requirements

The first thing that you need to ask yourself before purchasing a standby generator is what are your power needs. The smallest units are about 7.5 kilowatts, 12.5 kilowatts is a common size, and you’ll see 20-kilowatts units and even larger.

The easiest way to determine exactly what you need is online by using the champion generator selector tool. There are other ways to make the calculation but this tool allows you to click on all the household items you want to power and then to tally it up and come to a final kilowatt output that you need for the generator for your home.

Maintenance

Well, a home standby generator does not require too much maintenance. You will have to change the oil about every hundred hours of operation. The air cleaner is going to need to be kept clean and the spark plug will have to be replaced from time to time.

You might know that not all generators produce the kind of electricity that is suitable for sensitive electronics. Using a standby generator is a better and safer way to power computers, various home equipment and even appliances with sensitive electronic controls.

The risk of damage from a portable generator these days is pretty low but the risk is even lower with a standby or an inverter. So how do you know if a given generator can put out power that is clean enough for you? Look for a rating called Total Harmonic Distortion or THD. If this figure is not more than 4-5% then you know that the given generator can power everything in your home safely.

Finding an Advisor

Home standby generators aren’t the kind of that most people can install on their own so the next step would be to find some kind of an advisor. To help you choose the size of the unit, the electrical layout and the fuel source that makes sense for you an electrician or a home standby generator dealer is the best person to turn to.

To help you choose the size of the unit, the electrical layout and the fuel source that makes sense for you an electrician or a home standby generator dealer is the best person to turn to.

An advisor will also help you to decide on exactly where to install the unit what sort of support pad you need and whether or not a load controller makes sense for your installation, also sometimes called demand control.

The bottom line is that you’ll be able to power more of your home with a smaller generator and at a lower cost.

FAQ’s

How does a standby generator work?

When your quality power gets shut off a home standby generator senses it and kicks into action within seconds. An automatic transfer switch provides power to specific areas of your home. Once the utility power is back online, the standby generator shuts itself down until it’s needed the next time.

Basically, standbys work more or less automatically. Special circuitry in the system detects when grid power goes down and the instant that happens a switch automatically disconnects your home from the grid and then makes an electrical connection to the generator itself.

While the engine is firing up now when grid power comes back on again the engine of the generator is switched off and the connection is automatically re-established to the grid. You will experience a small pause or flicker and power as the generator kicks in, but, this is just a momentary thing.

How long can a standby generator run?

It might depend on which standby generator you are using. It has been recommended by various manufacturers to use your generator to have a limit of 500 hours of use at the most. With proper maintenance a standby generator can last around 30 years, also depending upon the quality or brand.

How much does a home standby generator cost?

You’ll have to pay anywhere from $2,100-4,500 for the unit itself plus an additional 40- 60% for the installation job.

What size generator do I need?

The key to selecting the right standby generator is to know what it is you want to run. Some people are interested in running the basics, heat a few lights, refrigerator, the microwave, a television, etc, If that’s the case then 3000-5000 watts would be quite enough to manage your needs.

On the other hand, some people want whole-house power and the peace of mind of knowing that their life will carry on unchanged even in the event of an extended power loss.

A few items that can really impact your power needs are central air-conditioning units, semi commercial-grade refrigerators, and freezers, hot tubs and large capacity water heaters. In that case, from 5000 to 6500 watts

How much does it cost to have a Generac standby generator installed?

Usually, you will see most of the Generac home standby generators starts from the range of around $1,949. Your installation costs may vary depending upon the system size, installation considerations, and also local building codes.
