The Best Way To Get A Backup Generator

Getting a backup generator involves several steps and considerations. Here are some steps that can help you get the best backup generator:

1. Determine your power needs

Before you buy a generator, you need to determine your power needs. Consider the appliances and devices that you want to run during a power outage and their total wattage.

2. Choose a fuel type

Backup generators can be powered by different types of fuel such as diesel, propane, or natural gas. Each fuel type has its advantages and disadvantages, so you need to consider your specific needs before making a choice.

3. Select the generator size

Generator size is measured in watts and is determined by the total wattage of the devices you want to power during an outage. Make sure to choose a generator size that meets your power needs.

4. Consider the generator features

Generators come with different features such as automatic start, noise levels, and fuel efficiency. Consider the features that are important to you before making a purchase.

5. Choose a reputable brand: There are many brands of generators in the market, but not all are created equal. Choose a reputable brand that is known for producing high-quality, reliable generators.

6. Hire a professional installer

Once you have chosen a generator, hire a professional installer to ensure that it is installed properly and safely. A professional can also advise you on the best location for the generator and provide ongoing maintenance and repairs.

Overall, getting a backup generator requires careful consideration of your power needs, fuel type, generator size, features, brand, and professional installation.

What Size Generator Do I Need?

The size of generator you need depends on your power requirements. To determine the size of generator you need, you will need to calculate the total wattage of all the appliances you intend to power. This can be done by checking the wattage ratings on each appliance and adding them up.

Once you have the total wattage, add 20% to that number to account for power surge and start-up requirements. This will give you the minimum size generator you need.

It’s important to note that larger generators may be required for specific appliances or tools that have high starting requirements, such as air conditioners, refrigerators, and power tools.

Consulting with a qualified electrician or generator specialist can also help you determine the appropriate size of generator for your specific needs.

2. Inverter generators

Inverter generators are a type of portable generator that produce clean and stable power, making them ideal for sensitive electronics such as laptops and smartphones. They are also quieter than traditional generators.

3. Standby generators

Standby generators are larger and are designed to provide backup power for an entire home or building. They are usually powered by propane or natural gas and are installed permanently outside the building.

4. Industrial generators

Industrial generators are larger and more powerful than standby generators and are used in commercial and industrial settings. They can provide power to large factories or buildings, and are often powered by diesel fuel.

5. Solar generators

Solar generators use solar panels to generate electricity, making them a clean and renewable source of power. They are often used in off-grid locations or for camping and outdoor activities.

How Much do Generators Cost?

The cost of generators can vary widely depending on their size, type, and features. Portable generators can cost anywhere from $200 to $2,000 or more, while standby generators can cost from $2,000 to $20,000 or more. Other factors that can affect the cost include brand, fuel type, and installation costs. It’s important to do your research and determine your power needs before purchasing a generator, as well as factor in ongoing maintenance and fuel costs.

Where Should Generators Be Installed?

Generators should be installed in a location that is well-ventilated, easily accessible for maintenance, and protected from weather elements. Ideally, they should be installed outdoors, at a safe distance from the building to avoid carbon monoxide build-up. It’s recommended to have a professional electrician or generator installer determine the best location for your generator based on your specific needs and local building codes.
