How to Choose A Power Outage Backup Generator

Choosing the right backup generator for a power outage can feel overwhelming with so many options on the market. You want something that kicks in when you need it, keeps things running, and fits your budget.

The right choice depends on your home, your power needs, and what kind of outages you experience. Let’s break down the most important factors to help you make the best decision for your situation.

Choosing Between a Portable Generator or Standby Generator for Backup Power

There are two main types of generators that provide backup power in case of a power outage and these are portable generators and standby generators.

If you want to get a backup generator, it’s important to know how these types of generators differ from one another.

Portable Generators

A portable generator is a compact device designed to provide electrical power when access to a standard power grid is unavailable. These smaller generators typically run on gasoline, diesel, or propane and convert mechanical energy into electricity and allow users to power various devices and appliances.

When using a portable generator, it’s important to consider the fuel type, power output, and the appliances you plan to run to choose the right model for your needs.

You’ll want to choose a portable generator if you value:

  • Mobility: Portable generators are designed for easy transportation, making them ideal for situations where you need power in multiple locations.
  • Versatility: These generators can power a wide range of devices, from small electronics to large appliances, depending on their power output.
  • Independence: Portable generators provide an independent power source, which is important during emergencies or when working in remote areas.
  • Ease of use: Setting up and operating a portable generator is straightforward, allowing users to quickly get power when they need it.

Standby Generators

A standby generator is a backup power system that automatically turns on when the primary electricity source fails. When a power outage occurs, its automatic transfer switch detects the loss of utility power. This quickly supplies clean, stable power keep essential appliances like air conditioning, medical equipment, and heating systems running.

It operates on fuel sources like natural gas, propane, or diesel and remains connected to your home. Standby generators are a reliable solution for maintaining power during unexpected outages, providing peace of mind for homeowners and businesses alike.

Go with a standby generator if you value:

  • Automatic activation: Standby generators kick in immediately when the power goes out, eliminating the need for manual start-up. They also tend to have have automatic shutoff features to save on fuel when the mains electricity comes back on.
  • Continuous power supply: Standby generators keep critical systems like heating, cooling, and security systems running during outages.
  • Fuel options: Standby generators can use different fuels, such as natural gas, propane, or diesel, depending on availability.
  • Scalability: Standby generators be sized to power just the essentials or the entire home depending on your needs.

How to Choose The Right Backup Generator

Once you’ve decided between a portable generator and a standby generator, the next step is to choose one that fits your specific needs. Here are a couple of things to consider:

Capacity and Size

The first thing to consider is determining how much power you need in a home generator. Here’s how you can figure it out:

  • Identify your power needs: List the appliances and systems you want to keep running during an outage. Include refrigerators, heating systems, lights, and any other critical items. Check the wattage for each to figure out your total power requirements.
  • Know generator sizes: Generators vary in size and power, measured in watts. Portable generators might provide between 1,000 and 5,000 watts, suitable for a few key appliances. Standby generators, which are larger and more permanent, can offer between 5,000 and 20,000 watts or more, covering most of your home’s needs.
  • Understand capacity ratings: Look at both running watts (continuous power) and starting watts (initial surge needed). Choose a generator with running wattage that matches or exceeds your total power needs. Don’t forget to account for surge requirements for appliances like refrigerators and air conditioners.
  • Plan for installation and maintenance: Portable generators need manual setup and refueling. Standby generators install permanently and start automatically during outages. Decide which option suits your needs and ability to manage.

Fuel Options

Generators come with several fuel options, each offering different advantages based on specific needs. Let’s break them down one by one.

  • Gasoline: Gasoline is easy to find and works well for small, portable generators. It’s a good choice for short-term use, like during power outages that last a few hours or days. However, gasoline tends to be less stable over time and isn’t ideal for long-term storage.
  • Diesel: Diesel fuel powers larger, more powerful generators. It’s best for heavy-duty use, especially in commercial or industrial settings where the generator needs to run for long periods. Diesel engines are durable and can handle higher loads, but they can be noisy.
  • Natural Gas
    A natural gas-powered generator is convenient if you already have a home or business connected to a natural gas line. It provides an uninterrupted fuel supply, making it great for standby generators that need to kick in during extended power outages. It tends to be cleaner and more reliable than gasoline or diesel.
  • Propane: Propane works well for generators that need to stay ready over long periods. It doesn’t degrade like gasoline, making it a good option for backup systems that may sit idle for months. You can store propane in tanks, so it’s a good fit for rural areas or places without easy access to gas lines.
  • Solar: Solar-powered generators rely on solar panels which harness sunlight to power your home. They’re best for small appliances or electronics, but they struggle with heavy power demands.

Cost, Installation, and Maintenance

Before you splurge on a new backup generator, it’s worth understanding the cost, installation, and maintenance requirements that go along with owning one. Here’s what you need to know:

Cost of Power Outage Backup Generators

The price of a power outage backup generator varies based on size and type. Portable generators, often used for smaller homes, typically cost between $500 and $1,500.

Larger standby generators, which automatically activate during a power loss, usually range from $3,000 to $10,000. These prices often don’t include installation costs, which can add $500 to $5,000 depending on the complexity.

Some systems may also require additional accessories such as transfer switches, which further increase the total cost.

You should consider fuel type when selecting a generator. Diesel, natural gas, and propane each come with different price tags.

For instance, diesel generators tend to be cheaper upfront, while natural gas models may save you money in the long term due to lower fuel costs.

Your specific energy needs and local fuel availability will often determine the best option for you.

Installation of Backup Generators

Installing a backup generator requires both electrical and mechanical work. A certified electrician typically connects the system to your home’s electrical panel.

This process can take several hours to a couple of days depending on the size of your home and the complexity of the system.

You may also need a contractor to prepare the site, especially for larger standby units. These generators usually need a concrete pad or other stable surface to sit on.

Local building codes often affect installation time and cost. Some areas require permits, while others may have regulations around noise levels or fuel storage.

Getting a professional to handle the installation ensures everything is done correctly and safely, preventing potential problems later.

Maintenance and Long-Term Costs

Regular maintenance helps keep your backup generator ready for unexpected outages. Most manufacturers recommend servicing your generator annually, with some needing more frequent checkups if they run on diesel or natural gas.

Expect to spend around $200 to $500 annually on inspections, oil changes, and other routine upkeep. The generator’s lifespan also depends on how often it gets used and how well you maintain it.

A properly cared-for standby generator can last anywhere from 10 to 30 years. Keeping it in top shape saves money in the long run and ensures it performs when you need it most.
