Over 2 million Texans lost power when Hurricane Beryl hit, and more than 400,000 people in Northern Ohio were left in the dark after a violent thunderstorm. As extreme weather events are on the rise, we are more vulnerable to power interruptions. The best defense? A reliable backup power source to keep your lights on and the internet running during power outages.

Previously, fuel-powered standby generators were the only option, but now quieter, fume-free, home battery backups offer a superior alternative. This guide will walk you through choosing the perfect battery backup system for your home.

What Is a Home Battery Backup?

A household battery backup system is essentially a powerful inverter paired with batteries that store energy from your home’s solar system or the electrical grid. When the grid goes down, the home storage battery kicks in, supplying power to your home. These systems range from large, whole-home solutions like the Tesla Powerwall or the BLUETTI EP900 ESS to more portable options that can handle essential loads or even provide power for your RV.

Key Factors in Choosing the Right Home Battery Backup

Output Power

Ensure the system can power your essential appliances and consider the startup power of large appliances such as air conditioners and clothes dryers. Look for pure sine wave output for stability, especially for sensitive electronics like computers.

Capacity

Choose a system with enough storage capacity, measured in watt-hours (Wh), to cover your needs. Some systems allow you to expand capacity as your energy needs grow.

Charging Speed

Faster charging means your backup is ready sooner. Pick systems supporting fast charging and multiple charging methods, like solar, wall outlets, and even generator charging.

Battery Type

Lithium-iron-phosphate (LiFePO₄) batteries are highly recommended for their safety, durability, and long life cycle. They offer more charge–discharge cycles compared to traditional lithium-ion batteries.

Solar Compatibility

If you have a solar panel system or plan to install one, ensure that your battery backup can integrate seamlessly with it. This allows you to harness renewable energy and reduce your reliance on the grid.

UPS Function

A built-in Uninterruptible Power Supply (UPS) ensures your system instantly switches over during an outage, protecting your PC, TV, router, and gaming device.
