In the United States, residential energy storage is rapidly becoming a lucrative market. Generac and Briggs & Stratton are just two examples of manufacturers who have successfully transitioned their expertise in the sector of backup generators into new product lines for residential batteries. Now, one of the most well-known brands in the battery industry, Duracell, has entered the market. The Duracell Power Center is a new home battery system that can store and utilize solar energy in addition to providing backup power for essential home appliances in the event that your home experiences a loss of electrical power. Whether or not you have solar panels, you can add this system to your home. It can also be used in combination with a new solar installation.

How does the Power Center stack up when compared to similar products? Is it suitable for your home? In the following post, we answer those questions and many more!

How does the Duracell Power Center work?

The Duracell Power Center is an excellent complement to solar panel systems. This is especially true if the utility company serving your home has reduced or eliminated net metering. Or implemented time-of-use rates, or instituted demand charges for residential electricity customers. In fact, the Power Center can shift modes to maximize savings on complex utility rates. With a solar energy system and Power Center, you can keep a consistent supply of electricity. Both in the daytime and at night. This is achievable if you store enough solar power during the day.

The Duracell Power Center, much like many other home battery solutions, is sized for day-to-day use at your residence and is primarily designed to be linked with a solar panel system. This is the case with the Duracell Power Center as well. When your solar panels create more electricity than you require in your house, you have the option of storing the excess electricity in your battery system rather than feeding it back into the grid if you have one installed. When your solar panels aren’t generating enough electricity to meet your home’s needs in the future, you can rely on the stored energy in your battery to keep you from having to rely on the utility company.

Key things to know about the Duracell Power Center

When analyzing the Duracell Power Center solar battery, there are a great number of important metrics and technical features that need to be examined. The size of the battery is the first consideration (its power and capacity). The second factor is its chemistry. The third feature is the discharge’s depth. Finally, roundtrip efficiency is among the most important factors.


The Duracell Power Center comes in five different configurations, each of which can store a different amount of kWh. Power and usable capacity are two important things to think about when comparing the Duracell Power Center to other home storage options. Power (measured in kW) indicates the amount of electricity that can be sent out at once, whereas useable capacity (measured in kWh) indicates the amount of electricity that can be stored in a fully charged battery. The Duracell Power Center has a constant power rating of 5 kW, a peak output of 8 kW, and a useful capacity between 14 and 42 kWh, depending on its configuration.

When comparing modular battery systems to other products on the market, it’s essential to consider two primary factors. First, the size of each step up in capacity (i.e., the smallest building block) indicates the size flexibility of the battery. 14 kWh is the largest building block that may be utilized to assemble the Duracell Power Center. The second consideration is the variety of possibilities (e.g., how big of a backup system can you make with the battery). With the Duracell Power Center, you can select between a 14-kWh base model and a 42-kWh model that can be upgraded. This is a greater selection than most batteries provide. configurations ranging from a 14-kWh base model to a 42-kWh model, which is greater than what most batteries offer.

Basic functionality

Different solar power batteries can do different things. For example, some batteries work well off-grid, while others have software that helps with rate arbitrage. Any solar installation can benefit from the durability and flexibility of the Duracell Power Center battery. It has scalable system sizing, over-the-air software updates, and a “load shifting” mode that saves money on utility rates (i.e., AC coupled or DC coupled).

Backup power

The Duracell Power Center offers completely automated backup power. This option is available due to the bidirectional inverter and transfer switch integrated into the device. The Power Center will therefore immediately power your home’s appliances in the case of a grid failure.


You may believe that Duracell is the industry leader in alkaline battery production. And you might also expect them to employ the same technology for their residential energy storage applications. Lithium iron phosphate, though, is what they use. If not, they use LFP, which is one of the most common ways to make lithium-ion batteries for homes. High-power rating, long cycle life, and safety are all hallmarks of LFP batteries. Check out our comparison of lithium-ion battery chemistries to learn more about how they compare to each other.

Duracell Power Center warranty coverage

The Power Center comes with a 10-year warranty, and Duracell guarantees that the battery will keep at least 70% of its ability to hold a charge during that time. Notably, Duracell says that the battery in the Power Center will last for 6,000 cycles, which would be 16 years if you used it every day.

Duracell’s battery technology is like that of other rechargeable batteries, both big and small. As time goes on, the battery loses some of its ability to hold a charge. Think about how the battery life of a brand-new smartphone compares to one that is a few years old. As you charge and drain your phone’s battery, it starts to lose some of its ability to hold a charge.

Your Power Center will show the same pattern of decreasing battery life. It does not mean that the product is defective. This is because it is normal for batteries of any kind. These include batteries used in electric vehicles and residential energy storage systems. Even rechargeable AA batteries lose some of their capacity to hold a charge over time. As a result, Duracell offers a warranty that guarantees a specific capacity for battery storage.
