How to select the best battery backups for home office and desktop applications

Battery backups are an essential component of the “new normal” work from home environment. 

Ensuring that critical home and small office applications are safeguarded by an uninterruptible power system (UPS) has never been more important. With a record number of telecommuters──coupled with widespread online learning for both lower- and higher-ed students──many utility companies are struggling to support the proliferation of power-hungry devices in homes. As a result, electronic equipment is more vulnerable than ever to harmful surges and power cuts.

A UPS with surge protection is one of the most simple, cost-effective investments to prevent data loss and equipment damage during a blackout or surge, seamlessly switching to battery and continuing to power connected equipment until the issue is resolved or you’re able to safely shut down devices.

To help you hone in on the optimal UPS solution for your home or small office, we’ve compiled the following 10 buying tips:

1) Determine the equipment you want to protect

Even the most brief surge or loss of electricity can be catastrophic to sensitive electronic equipment in home and small office environments, with sudden shutdowns capable of corrupting files and damaging or destroying home devices. But it’s not just your PCs, routers, modems, small servers, switches and storage devices that need protection. Desktop UPSs aren’t all work and no play; battery backup is also ideal to safeguard numerous other home devices including TVs, gaming consoles, home theater solutions, security systems and household medical equipment such as CPAP machines for sleep apnea. 

A small, inexpensive desktop UPS can keep home Wi-Fi and internet systems online during short outages or brownouts, while more advanced battery backup models can enable home office equipment and workstations to remain operational during business hours ─ or at least long enough to save work-in-progress and safely shut down. The same applies to video consoles, so gamers don’t surrender their hard-fought progress.

2) Consider the level of protection you need

Different UPS topologies provide varying degrees of protection against power problems. Determining the best UPS for home use model depends on your budget, the type of equipment being protected and the environment. Standby UPS such as the Eaton Ellipse ECO UPS and line-interactive models like the Eaton 5S will properly support the vast majority of desktop and small-office/home-office (SOHO) applications.

The most cost-effective topology available, a standby or offline UPS allows equipment to run off of utility power while providing continuous surge protection, then switches to battery mode during voltage sags or outages. Standby topology is best suited for equipment such as LCD monitors, docking stations, modems and routers.

With a highly reliable and efficient design, line-interactive UPSs actively regulate voltage by either boosting or decreasing utility voltage as needed before allowing it to pass to the protected equipment. Line-interactive is best suited for high-end PCs, gaming PCs and home network equipment.

3) Add up the watts

One of the most important factors when buying a battery backup for home is determining the size you need. While a UPS is rated in both volt-amperes (VA) and watts, the watts measurement is the key rating because it represents the amount of real power available. Verify the maximum wattage rating for each piece of equipment you want to connect to your UPS (which can be found on the equipments' labels) and add up the total wattage to determine the wattage size you need in a UPS. Eaton’s UPS selector is loaded with the wattage rating for hundreds of the most commonly connected pieces of equipment, so this tool can help you calculate the maximum capacity. To see how wattage impacts a UPS runtime, visit our battery runtimes page. Each UPS model has a graph that displays the runtime based on the total wattage load. 

4) Do you need sine wave protection?

The waveform of electrical power is a sine wave, which represents a smooth periodic oscillation. However, standby UPSs and some line-interactive models provide a simulated or square wave output while running on battery power. Because this simulated power output can stress and harm the power supply in sensitive electronics such as servers, a line-interactive UPS with sine wave output is a better choice for these types of equipment.

5) Make sure the UPS has enough outlet receptacles

It is very important that the battery backup solution you choose includes enough output receptacles so you can plug in all of your home equipment. The right battery backup doesn't just have the right number of receptacles, though. It will also have enough physical space around the receptacles to fit your plugs. Devices with big transformer block plugs take up more space than a standard plug and may cover up more than one outlet on the UPS.

6) What’s your noise toleration level?

UPS systems can be surprisingly loud and many are designed to be deployed in even noisier network closets, server rooms and industrial settings. If you need a quiet environment for concentration or conference calls, be sure to check a unit’s audible noise specifications (measured in dBA). Both of these desktop UPS models, The Eaton 5S, is known for providing very quiet operation.

7) Consider where and how you will install the UPS

A UPS system requires clearance space in order to properly vent heat, so it is important not to install the unit in a tight area or enclosed space. If space is a concern, consider the sleek design of this UPS with surge protection (3S), which fits neatly under a desk. In addition, the slim form factor of the 5S enables the UPS to easily fit into small spaces, with the convenient option of using it as a tower or as a desktop monitor stand.

8) Want UPS status at a glance?

If you are the type of person who appreciates immediate access to critical information, then you may want an at-home UPS unit that includes an LCD interface. These displays provide key data on UPS system operation, such as battery time and outage tracking. Some battery backups for home models also allow users to configure parameters including output voltage, audible alarm and power input sensitivity. Both the Eaton 5S provide user-friendly LCD interfaces.

9) All warranties are not created equal

When comparing desktops models for home use, be sure to check the warranty. How long does it last? Does it cover both the UPS and its batteries? Is shipping included? Are the batteries user-replaceable?​ Eaton products—including the Eaton Ellipse ECO UPS, 5S—come with an industry-leading, comprehensive 3-year warranty that covers both the UPS unit and its batteries. For more coverage, look at extended warranty plans that allow you to get an overnight replacement for your UPS if something goes wrong with it.

10) Add another layer of protection with software

While UPS battery backup are designed to protect your connected equipment from power anomalies and provide a backup source during a power failure, they can only do so much if electricity is not restored before your available battery expires. Yet by pairing the 5S or 5SC UPS with Eaton's Intelligent Power Protector (IPP), you can avoid data loss by the software facilitating automatic, graceful shutdown of computers, servers and network devices, saving all work-in-progress. IPP’s versatile user interface displays detailed information about connected equipment through USB and serial or network communication.
