Gain Independence from the Grid

Battery energy storage systems are rapidly gaining popularity among homeowners as power outages grow more frequent due to grid fragility and increasingly severe weather events. These systems feature large-capacity rechargeable batteries (usually lithium ion) and are scalable to keep pace with your energy needs. They’re often mounted on garage walls, but can also be installed outdoors in warmer climates.

What Is Battery Energy Storage?

A battery storage system features a large rechargeable battery (usually lithium ion) that can be mounted on a garage wall or installed outdoors in warmer climates. The battery can be recharged using power from the grid or—if available—solar panels or a bidirectional EV charger. That stored energy can then be used to run your home when it’s advantageous for you.

*Note: To power your house, solar energy must be converted from DC electricity to AC by a device known as an inverter. Some battery storage systems come with an inverter built in; for others, you’ll need to buy one separately.

Individual Components

The alternative to an all-in-one system is buying and connecting individual components. Besides the battery itself, these may include:

Inverter

Converts the battery’s DC power to AC, which most homes run on, and vice versa so that power can flow both to and from the battery.

Gateway

The “brains” of the system, coordinating between all components and ensuring an uninterrupted power supply in case of a blackout.

Today’s homeowners are increasingly opting for all-in-one systems which include everything they need to:

  • Store energy from the grid, solar panels or bidirectional EV chargers
  • Run their homes during peak hours when electricity is costliest
  • Provide backup power to critical circuits if the grid goes down

What Are the Benefits of Battery Storage?

With a battery energy storage system, your home becomes a “nanogrid” capable of running off of the public grid for hours at a time. Advantages include:

Saving on
Electricity Costs

Run your home more cost-efficiently by using power from your battery system at peak times when utility rates are highest. Then replenish your battery from the public grid during off-peak hours.

Improving Your
Home’s Resilience

To get the most out of your investment, Qmerit recommends using your battery system not only to run your home during peak hours, but also as a backup energy source in the event of a power outage.

Keeping Critical
Appliances Running

If you use your battery system for backup power, you can prioritize which appliances will keep running uninterrupted during a blackout. These may include your refrigerator, stove and hot water heater, for example.

Choosing How
You Charge

Have solar panels or a bidirectional EV charger? You can use them to replenish your battery storage system rather than relying on power from the grid, further increasing your energy independence.

What’s Next on Your Electrification Journey?

Solar & Smart Panels

With rooftop solar panels, you can charge your battery storage system at no cost. Adding a smart electrical panel allows you to control all your electrification technologies from your smartphone.

Solar Panels

Generate clean power that you can use yourself or sell back to the grid.

Smart Panel

Monitor and manage your energy use, including when your house runs on grid electricity vs. battery storage.
