What Can a Backup Battery Power During a Power Outage?

A backup battery storage system can power your home during a power outage, but exactly what it can run depends on the size of your battery, your home's energy usage, and which appliances you want to keep running.

For Oregon homeowners and businesses, battery backup can be especially valuable during wildfire season, when power outages can occur because of wildfire damage or when utilities shut off power as a safety precaution.

So, what can a home battery actually power?

What Can a Home Battery Power?

A properly sized battery can provide backup power to many of the appliances and systems you use every day, including:

• Refrigerators and freezers

• Lights

• Wi-Fi and internet equipment

• TVs and electronics

• Phone chargers

• Security systems

• Heating and cooling

• Well pumps

• Sump pumps

• Kitchen appliances

• Medical equipment

• Select 240-volt appliances

The exact appliances you can run depend on your battery system and your home's electrical setup. Some homeowners choose to back up only their essential appliances, while others want enough battery capacity to power most or all of their home.

Can a Battery Power My Whole House?

Yes, a battery can be sized to provide whole-home backup power. However, the larger your home's electrical loads, the more battery capacity you may need.

High-energy appliances such as electric water heaters, heat pumps, air conditioners, ovens, dryers, and EV chargers can use significantly more electricity than smaller appliances. That's why battery systems should be sized based on what you actually want to power during an outage.

Why Battery Backup Matters During Wildfire Season

Wildfire season can bring unexpected power outages to Oregon. In some situations, utilities may proactively shut off power in high-risk areas to reduce wildfire risk.

For homeowners, losing power can affect more than just the lights. An outage can impact refrigeration, heating and cooling, well pumps, internet, security systems, and other essential equipment. A battery backup system can help keep those systems running when the grid is unavailable. And because you may not know exactly how long a wildfire-related outage will last, having stored energy available can provide an added layer of preparedness.
