Batteries or Standby Generators

Batteries vs. Generators

Choosing the Right Home Backup for Your Needs

Everybody needs a backup plan. Because let’s face it: Despite your best efforts, becoming a pro quarterback might not be in the cards. Or a Hollywood movie star, for that matter. In life, it’s good to have a Plan B. The same goes for your home. Because like life, the weather can throw you curveballs, too. Maybe it's a summer storm knocking out the grid, or a winter ice storm snapping power lines. Whatever the reason, losing power during a storm can make things … uncomfortable.

That's where home backup power comes into play. Today, home batteries and standby generators vie as the two main contenders to back up your home during power outages. But how do you choose the right backup power system for your needs? Let’s explore the pros and cons of both systems.

Home batteries: Stored power at the ready

Power outage? What power outage? With a home backup battery, when the grid goes down, you can power back up with the flick of a switch. Instantly, your essential electronics and appliances will kick back to life. That's the beauty of home battery backup systems. These clever devices store energy when the grid is on, then take over when the power goes out, keeping your home running smoothly.

The Perks of Batteries

  • Easy Fixes: Battery systems are typically maintenance-free. No need to worry about messy fuel or complicated upkeep.
  • Quiet as a Whisper: Unlike generators, batteries operate silently, keeping your peace and quiet even during an outage.
  • Eco-Friendly: Batteries don't rely on fuel, so you can keep the power on and run a sustainable home.

The Cons of Batteries

  • Wait Times: While batteries kick in quickly, they may require a few seconds for your appliances to adjust.
  • Expensive: The upfront cost of battery systems can be higher than generators —an average-size home battery backup system runs between $10,000 and $20,000.
  • Limited Power Supply: Unlike generators that can run if you provide fuel, your battery backup can only store so much backup power – sometimes as little as a few hours. Unless hooked up to a solar system, you cannot get extra power during an outage.

Standby generator: Power on demand

Think of a standby generator as a dependable backup for those situations when you need spare power unconnected to the grid. Fueled by natural gas, propane or gasoline, standby generators ensure your essential appliances, lights and even comfort features like air conditioning stay operational, no matter what the weather throws your way.

The Perks of Generators

  • Start in a Flash: Generators typically start up quickly, getting your power back on in a jiffy.
  • Powerhouse for Electricity: Generators can provide a surge of power, enough power to run your entire home.
  • Ready for the Long Haul: As long as you have fuel, a generator can keep your home powered for extended periods. A typical generator’s life span lasts 25-40 years depending on usage.
  • Cheaper: On average, the price of purchasing and installing a standby generator can range from $7,000 to $15,000.

The Cons of Generators

  • More Maintenance: Generators require regular maintenance, including oil changes and filter replacements.
  • Noisy: Standby generators can be quite loud when running. Portable gas generators typically produce between 80 and 100 decibels (dB) of noise when operating ­̶ at least 10 dB above the recommended safety threshold.
  • Not Eco-Friendly: Generators burn fuel (gas, diesel or natural gas) and must be installed outside the home. Generator exhaust contains carbon monoxide and other toxic emissions.

Choosing Your Backup Power Champion

Now that you know the strengths and weaknesses of batteries and generators, it's time to pick your champion. Consider these factors:

  • Power Requirement: How much power do you need during an outage? Do you just need to keep essential appliances running, or do you want to power your entire home?
  • Budget Constraints: Battery systems have a higher upfront cost, while generators require ongoing maintenance expenses.
  • Ease of Maintenance: If you're not handy, a battery system might be a better fit.
  • Reliability: How important is it for you to have uninterrupted power during an outage?

The Final Word

Ultimately, the best backup power system for you depends on your individual needs and priorities. Don't be afraid to reach out to a qualified electrician to discuss your options and find the perfect fit for your home. And remember, Duke Energy is always here to help! Sign up for Outage Alerts to get notified of power outages in your area and receive restoration updates.
