As far as how long they can keep your home powered, standby generators easily outperform battery backups. As long as you have enough fuel, generators can run continuously for up to three weeks at a time (if necessary). Some home batteries are more like oversized portable power stations, and require little more than having an electrician install a transfer switch or smart electrical panel. But generators need fuel to run, which means that you'll spend more over time to maintain a steady fuel supply. If you have solar panels, you'll be able to store any excess electricity generated by your solar panels.
What will this cost—and do you really need it?

That's because, like other types of batteries, battery backups lose storage capacity over time. In addition, you'll be able to use your battery bank in the event that the grid goes down due to a failure, natural disaster or even a solar flare. A backup generator can also help keep the power on in an emergency (and charge your batteries), but it requires burning fossil fuels, usually either gas or propane. The simplest way to think of batteries is to imagine that the electricity in your house flows through wires in much the same way as water through plumbing. Batteries fill the role of a storage tank, making electricity readily available when it's needed, just as indoor pressure tanks and water heaters do with water. In 2020, according to US Energy Information Administration figures, the typical US home consumed 29.3 kilowatt-hours per day.

A single battery may not be able to power your whole home, so you’ll need to prioritize what’s essential, such as lights, outlets, air conditioning, the sump pump, and so on. But if you want to run everything in your house, some systems allow you to stack or piggyback more than one unit to achieve the level of backup you need. It’s currently the most powerful of any residential battery storage system on the market, and one battery can provide enough power for starting energy hogs such as large air conditioners or well pumps. Cost is also an important factor to consider when designing a battery system. If your power requirements exceed 15KWh of inverter power or 30KWh per day for your batteries, the cost of the system may become prohibitive. It's also important to take into account potential inefficiencies, voltage drops, and other losses to ensure that your system can handle any situation that may arise.

Even if you’re not prone to power outages, many UPS models also include surge protection features. An automatic voltage regulator smoothes over brownouts and spikes without needing to change your battery. It’s one of several capabilities you’ll want to look for in the best battery backups. Two EcoFlow DELTA Pros and additional smart batteries may be overkill if you have a tiny home or only want to power a few appliances. The EcoFlow DELTA 2, paired with solar panels, provides an affordable solar generator for relatively low-level backup needs.
Most battery systems provide partial-home backup, meaning you can continue running your most critical loads – like your phone, computer, Internet, refrigerator, and some lights – during an outage, but not your entire home. Check out this article to learn more about how much of your house you can power with a typical battery and for how long. The Powerwall is a good investment for home solar systems or homes with general backup energy storage needs.

For most of the UPS models in this guide, we focused on the home user, so we selected units that were less than $300. However, for one, “Best for businesses,” we selected a more expensive model since most small business owners are likely to pay more for a more robust UPS that can handle more machines. Adding batteries is a significant expense for any system, but the good news is that nearly a third will come back to you in the form of the 30% federal renewable energy tax credit.
Backup generators vs. energy storage: An overview
After being acquired by Lithion Battery in 2021, HomeGrid has solidified its place in the battery storage market. The HomeGrid Stack'd Series is flexible and easy to maintain and install. Due to its affordability, scalability, and high performance, HomeGrid's batteries are some of the best for those looking to go off-grid. It includes FranklinWH's load management system, the aGate, allowing you to easily monitor your storage system and take action based on those insights.
LFP batteries, being less energy-dense, need to be somewhat larger for a given capacity, but they are less sensitive to heat generation and may have higher charge-discharge cycles. Ultimately, you’ll wind up with whichever type of battery best fits into the design you settle on with your contractor. On the other hand, standby generators connect to your home's electrical panel and kick on automatically when the power goes out. Generators run on fuel to keep your electricity on during an outage -- typically natural gas, liquid propane or diesel. Other generators have a "dual fuel" feature, meaning that they can run on either natural gas or liquid propane. These products or services have not been evaluated by CNET's editorial staff.

With suitcase-style wheels and a handle, the 99 lb (45 kg) EcoFlow DELTA Pro is the ultimate in compact power solutions. The EcoFlow DELTA Pro Portable Power Station is a higher capacity option than the EcoFlow DELTA 2, starting at 3.6 kWh and expandable to 25 kWh. The EcoFlow DELTA Pro can run multiple high-wattage appliances and expand to a whole house backup power solution. It provides the plug-and-play options of the EcoFlow DELTA 2 but with a much higher capacity to power more of your appliances and systems for longer. A small off-grid solar system with enough battery capacity for the basics (no air conditioning or electric heaters allowed) using a pair of high-capacity flooded lead acid batteries can be had for $500 total. Upgrading to lithium-ion costs $1,300 for a system with comparable capacity.
The federal solar tax credit is one of the most valuable incentives that most homeowners qualify for. While one Tesla Powerwall costs $9,300, the more you buy, the more you can save per battery. Plus, there are ways to reduce your expense, such as solar incentives, which are covered in our guide.
Adding two Powerwalls in Texas increased our cost to $16,000 plus $1,200 for the additional equipment, totaling $17,200. A single Tesla Powerwall battery costs around $9,300 according to Tesla’s website. You can learn more about costs in your area by submitting your address on Tesla’s site. See what you should budget for and how to save money on your solar battery.
