Comparing battery backup options: whole-home backup, solar generators, and UPS’s (2023)

I have good news and bad news.

The bad news first. Blackouts are becoming more frequent, with major outages now 10 times more common than they were in the mid-1980s, according to one study. This worsening power situation is the result of aging transmission grids and increasing extreme weather events induced by climate change.

These power headaches come at a bad time; we now have more devices and are working from home more than ever before, meaning our need for a constant and reliable supply of electricity is only growing.

Now the good news: in recent years, there have been many technological advancements when it comes to battery backup solutions, so much so that many experts are calling this the ‘golden age of batteries’. There is now a whole range of battery products across different segments of the market, all cheaper and more powerful than their predecessors.

So what battery backup solutions should you be looking at? Should you get a UPS, a whole-home battery, or something in between? This blog will help you figure that out. We’ll look at the pros and cons of each option, their costs, and then recommend the best ones for you to buy.

    Which type of battery backup is right for you?

    Here are the most popular types of battery backup. Choose the right device based on your needs.

    1. UPS (Uninterrupted Power Supply)

    Used for: Short-term backup power

    We’ve all been there: you’re finishing up an important task on one of your devices when the power goes out. Whatever it was - a work project, an online form submission, or maybe even a video game - the power outage resulted in loss of unsaved data, and along with it all of your progress, your momentum, and the time it will take you to get back to where you were. Or even worse, there’s a surge of power that fries the power unit in your device, rendering it useless.

    Enter the UPS, which is short for Uninterruptible Power Supply. It offers surge protection to multiple devices, protecting them during storms and brownouts. In the event of a power outage, it will keep them on long enough for you to finish what you’re doing, save your work (or play), and safely shut down.

    UPS’s are especially useful in protecting servers, which can suffer hardware damage and data losses if there is voltage fluctuation or a blackout. They have been serving this purpose for many years now, and have been a common feature in homes and offices since the 1990s.

    With the passage of time, UPS’s have become smaller, more powerful and, best of all, cheaper. You can also find UPS’s designed for different sub-purposes, for instance a mini-UPS or router-UPS. These are smaller UPS’s designed specifically to backup your WiFi router. They have a small, unobtrusive form factor and generally provide up to four hours of backup for a stand router. This is an easy way to ensure uninterrupted internet access for your mobile devices and laptops during a longer blackout.

    A UPS is best if you:

    • Are on a budget
    • Run a server and you want to protect yourself from hardware failure or data loss caused by a brownout or sudden shutdown
    • Work on a PC and you want to be able to save your work and safely shut down if needed
    • Want several hours of backup power for a single small device, such as a Wi-Fi router

    2. Solar generators

    Used for: Powering multiple appliances for several hours

    Solar generators aren’t really generators at all - they’re actually portable battery storage systems. However, because they are used for the same purposes as traditional generators - that is, providing a steady source of backup power - the name ‘solar generator’ has stuck.

    Solar generators offer a great deal of flexibility. In addition to being portable, they can be charged in many different ways:

    • With the provided solar panels (which are small and easy to set up)
    • Via a wall charger that that can be plugged into a regular wall socket
    • In some cases, via a charger that can be connected to a car’s 12V socket

    There are other advantages that solar generators have over traditional diesel-powered generators. For one, they are completely silent. Furthermore, they usually come equipped with a large number of USB ports, 12V DC sockets, and 120V AC power outlets, making them a more versatile option.

    Once fully charged, solar generators offer between 0.5 kilowatt-hours (kWh) and 2 kWh, depending on the size and model. Battery backup of 0.5 kWh will allow you to run small emergency items like a modem, lights, and small fans for several hours. With 2 kWh of battery backup, you have a couple of options: power the aforementioned small emergency items for as long as a day, or you can opt for a few hours but with additional things like a fridge and TV on, as well.

    Just note that if you want to use your solar generators for home backup power - as opposed to their typical outdoor uses - you’ll need to connect it to your electrical panel via a generator transfer switch, same as you would with a traditional diesel-powered generator.

    Your other option is to simply carry the solar generator to where you want to use it.

    A solar generator is best if you:

    • Want to run and charge multiple appliances, as well as charge devices for several hours during a blackout
    • Need a portable solution than can be carried around the home, and even used for camping or other outdoor activities

    3. Whole-home batteries

    Used for: Powering your house for hours, or even days

    A whole-home battery is a battery system that’s capable of powering an entire home. They are designed to handle high instantaneous power loads, meaning they can run several large appliances simultaneously. They also have large storage capacities, which enables continuous operation for many hours at a time.

    Whole-home batteries are often called ‘solar batteries’, since it is most common to use them in conjunction with a solar panel setup. The reason for this is simple: when a solar battery is purchased with solar panels, it automatically qualifies not just for the 30% federal solar tax credit, but for a variety of state and other local incentives, too - most notably California’s SGIP rebate program.

    In 2022, most people considering whole-home batteries are looking at smart lithium battery solutions such as a Tesla Powerwall or LG Chem Resu. These battery products are small, efficient, and durable. This is especially true when you compare them to older battery technology like lead-acid batteries. (Lead-acid batteries do still have some use cases; we have an article comparing different battery types).

    I should point out here that it is actually possible to get a solar battery without actually installing solar panels. You could, for instance, set up a LG Chem Resu to charge using grid power, thus providing you a backup option for when there’s a power outage. Starting in 2023, you’ll even be able to claim the 30% tax credit on a standalone battery purchase. However, without solar panels, you’ll have to charge the battery with expensive grid power (instead of cheap solar power), and you won’t be able to charge your battery in the event of a prolonged power outage.

    A whole-home battery is best if you:

    • Are going to buy solar panels, or want to pair the battery with an existing solar setup
    • Live in an area prone to frequent blackouts and want a clean backup option that can power your entire home
    • You want to use the battery to avoid expensive peak electricity rates
    • You want to replace a loud and dirty gas generator

This means that the Titan is best suited to support critical loads in your house.

    When the sun is out, the 1,000-watts of solar panels can run your electronic devices without draining the battery, and it’s able to charge in as little as 4 hours thanks to its high-powered AC output charger.

    The Titan 1000 battery weighs in at 35 pounds and includes five foldable monocrystalline solar panels, so it can be used on the go but is also well suited as a home power backup system.

    Best whole-home batteries

    1. LG Chem RESU Prime battery system

    Comparing battery backup options: whole-home backup, solar generators, and UPS’s (6)

    The LG Chem Resu Prime is a DC-coupled battery, offering backup power with minimal efficiency losses. Image source: LG Energy Solution

    Best: DC-coupled battery

    Price: $11,000 to $15,000 installed

    Capacity: 10 & 16 kWh

    The LG Chem RESU battery is a lithium-ion battery that captures solar energy and stores it for later use in residential settings. In 2021, LG Chem introduced new higher-capacity RESU Prime batteries in order to serve the needs of the marketplace affected by power outages and to more directly compete with Tesla.

    The LG Chem RESU Prime can be used as either whole-home backup during outages or as a day-to-day battery pack, meaning it charges and discharges over a traditional 24-hour period.

    The RESU Prime comes in capacities of 10 and 16 kWh, and can be installed in pairs to create whole-home backup for even larger homes that use a lot of electricity.

    LG’s RESU Prime batteries come with a warranty that ensures they will retain at least 70% capacity after a 10-year period, which matches the warranty offered by both sonnen and Tesla.

    The average cost of the LG Chem system, including supporting equipment and installation, ranges from $11,000 to $15,000 - depending on your location, battery capacity, and installation charges.

    LG Chem batteries are DC-coupled and can only be used for backup with a central string inverter or by adding an additional battery inverter, which adds expense and complexity to the installation. That said, DC-coupled batteries are more efficient than their AC-coupled counterparts, such as the Tesla Powerwall.

    2. sonnenCore battery

    Comparing battery backup options: whole-home backup, solar generators, and UPS’s (7)

    The sonnenCore looks great indoors. Image source: sonnen

    Best: Tesla Powerwall alternative

    Price: ~$11,500 installed

    (Video) AUTOMATIC Battery Backup for your ENTIRE HOUSE! - Ecoflow Smart Home Panel

    Capacity: 10 kWh

    German energy company sonnen (yes, the s isn’t capitalized) has been making commercial batteries for a while. With the release of the sonnenCore, they are targeting the U.S. residential storage segment.

    The sonnenCore is an all-in-one battery storage system that offers 10 kWh storage. It’s an AC-coupled battery, which brings it into direct competition with the current market leader, the Tesla Powerwall.

    Its big selling point is that it uses lithium iron phosphate (LiFePO4) battery technology, which is safer and better for the environment. This puts it at an advantage over the Powerwall, which uses the more common lithium nickel manganese cobalt chemistry.

    The sonnenCore currently costs $9,500 before installation. This is substantially cheaper than their sonnenEco or EcoLinx models. However, this puts it behind the Powerwall, which boasts a large storage capacity and a lower overall price.

    sonnen offers a 10-year warranty that ensures the battery will maintain up to 70% of its storage capacity over a 10-year lifespan; this is pretty standard for solar batteries.

    3. Tesla Powerwall

    Comparing battery backup options: whole-home backup, solar generators, and UPS’s (8)

    Since its release, the Tesla Powerwall has been the market leader in the residential storage sector. It now faces stiff competition from LG Chem and sonnen. Image source: Tesla

    Best: Value

    Cost: $11,000 installed

    Capacity: 13.5 kWh

    At the time of its release in 2015, the Tesla Powerwall was a revolutionary step forward: it was the first lithium battery that was both powerful and affordable enough for mainstream residential use.

    Since then, other companies, including the aforementioned LG Chem and sonnen, have released competing products that are relatively similar in quality and price. The Powerwall, however, remains the most widely-installed battery backup for home use.

    The current variant Powerwall+ comes with a 13.5 kWh usable capacity. Its lifespan is pretty standard for lithium ion batteries - it will operate at 70% of its original capacity after 10 years.

    The Tesla Powerwall costs $8,500 for the battery; expect installation costs to add another $2,000-$3,000 to the price. The Powerwall offers excellent value, with the cheapest price per kWh of storage among major battery brands.

    But there’s a couple of downsides to be aware of.

    The first is that it’s an AC-coupled battery. While this has its advantages (it’s very easy to retrofit a Powerwall to an existing solar power system) it also has a disadvantage, namely lower efficiency. That’s because the Powerwall receives AC power as an input, converts it into DC power for storage, and then converts it back into AC power as an output. Each time there is an AC-DC or DC-AC power conversion there is a small energy loss (DC batteries, which receive and discharge DC power, avoid this problem).

    More importantly, the Tesla Powerwall is hard to purchase as a standalone unit. Nowadays the only way to get one is as part of complete solar installation from Tesla. Tesla has a poor track record with their past solar installations - as evidenced by their poor review scores - so it’s difficult to recommend them for this purpose.
